Junior BCP

1. INTRODUCTION

The Junior BCP Series are dehumidiﬁ cation units, using a cooling

circuit with total condensation heat recovery, specially designed for

conventional covered swimming pools and other dehumidiﬁ cation

applications.

These units have been designed for assembly inside the premises.

After manufacturing, all units are charged with refrigerant and are tested

at the factory, verifying the correct operation of all their components.

In this brochure are described the actions and safety norms for a

correct unit handling.

3. OPERATING MODE

In these units, the circuit condenses over an air coil positioned at the

outlet for the air originating from the evaporator, heating its cold and

dry outlet air before discharging it to the optional auxiliary coil.

In models 70 to 90, and optionally in models 40 to 60, in parallel to the

coil, a plate exchanger made of stainless steel SMO 254 alloyed with

chrome and molybdenum is ﬁ tted. It has high resistance to corrosion in

the presence of chlorides, which recovers part of the energy consumed

during the evaporation process.

6. SAFETY ADVICE

To avoid any risk of accident during installation, commissioning or

maintenance, it is obligatory to take into consideration the following

specifications for the units: refrigerated circuits under pressure,

refrigerant presence, voltage presence and implantation. Because

of all of this, only qualiﬁ ed and experienced personnel can perform

maintenance tasks or unit repairs.

These units work with refrigerant gas

Refrigerant leaks:

A periodical check must be performed for refrigerant gas leaks as per

Regulation (CE) Nº842/2006 over certain greenhouse effect ﬂ uoride

gases.

Refrigerant leaks can cause:

- Displacement of available oxygen, its inhalation can cause

arrhythmias (work must be undertaken in well-ventilated areas).

- Eye irritations can result from contact as well as burns (suitable

safety goggles must be worn).

It is required to follow the recommendations and instructions

in the maintenance brochures, the labels, and the speciﬁ c

instructions. It is necessary to comply with the norms and

regulations in effect.

The compressor and line surfaces can reach temperatures

above 100ºC causing burns to the body. In the same fashion,

under certain conditions these surfaces can reach very cold

temperatures that can cause freezing risks.

Use safety gloves and gloves whilst working. Be careful with

sharp parts or elements in the unit.

7. TRANSPORT

The unit must be handled with care to avoid transport damage. Thus

we recommend:

- For large dimension units, appropriate transports should be used for

this purpose.

- For transport in a container, one must be selected that is easy to

load and unload.

- Do not dispose of the pallet nor the packaging materials until the

machine is in its ﬁ nal location.

- Transport the units using the forklift truck or slings however only by

the hoisting points on the unit.

The slings must be separated using a strut to avoid deteriorating the

bodywork.

Location designation

Before moving the unit, ensure that all panels are fastened in place.

Lift and lower with care.

When choosing the location, in any way the selected fashion, the

following precautions have to be taken into consideration:

- It is mandatory to comply with norm EN 378-3 on Safety and

Environmental Requirements. Part 3: "In situ" installation and

protection to people.

- It is necessary to check that the structure supports the unit weight

(please see weights in the characteristics sheet).

- The area where the unit will be located must be perfectly accessible

for cleaning and maintenance operations (check minimum free space

for maintenance).

- Foresee appropriate bumping devices in all the installation so that

noise and vibration transmission is avoided.

- All models can be installed on the ﬂ oor or on a brick frame or steel

proﬁ le. In any case, check that the unit is perfectly level.

- Avoid placing obstacles in the air outlet or return.

- Ensure that the location of the outlet and return grilles does not

generate air recirculation.

- The return fan module with free-cooling 3 dampers (optional) is a

box separate from the unit. The engineer must plan a duct for joining

the unit with this module.

- These units have been studied for silent operation. Nevertheless,

the installation location must be taken into account and if the noise

emitted by the unit is greater than that estimated for the installation

plan the following:

• a possible acoustic study,

• suitable acoustic treatment if required,

• the necessary implementation precautions.

Note: consult the acoustic information provided in the technical

brochure.

9. CHECKING BEFORE COMMISSIONING

Installation norms

To have electrical power to the unit: wire intake, conductor section and

their calculations, protections, etc..., ask the information provided in this

document (refer to technical characteristic table), the electrical scheme

included with the unit and norms in effect that regulate the installation

of air conditioning units and electrical receivers. Verify that electrical

power corresponds to the one on the data plate and that the voltage

remains constant.

Check that the electrical connections are correct and tight

(an electrical diagram is included with each unit, along with

its legend).

Note: All connections on the site are the responsibility

of the engineer.

To prevent electrical shocks, make all electrical connections

before energizing the unit. Check that the automatic switch

is closed. Omitting this can cause personal damage. Make

the ground connection before any other electrical connection.

V-220004

V-220005

It is necessary that the installation wiring complies with the

effective legislation. The installer must ﬁ x line protection

elements according to the effective legislation.

Electrical Connections

Control

The Junior BCP units include an electromechanical control module for

relative humidity: humidity probe and digital controller for one stage

which acts on the compressor operation.

Electrical heater (optional)

The electrical heaters acquired with the unit will be incorporated to it

modifying the electric panel in the factory to ensure that it is compatible

with the control in the unit.

The electrical heaters requested for units already shipped will be sent

in a kit, and the installer will need to assemble the necessary elements

for the operation of the unit to assemble and for the compliance with the

legal regulations that are applied to the modiﬁ ed unit in terms of safety.

Air ducts connections

The air outlet and return ducts must be calculated in accordance with

the nominal ﬂ ow and the unit's available pressure (refer to the technical

characteristics table). The duct calculation and design must be made

by qualiﬁ ed technical personnel.

It is advisable to take into consideration the following recommendations:

- Curves in the fan discharge outlet must be avoided. It is

recommendable to have a straight section of duct measuring

approximately 1 metre. If it is not possible, they must be as smooth

as possible, using indoor deﬂ ectors when the duct is of large

dimensions.

- When making the ducts, direction sharp changes must be avoided

since they can generate occasional pressure drops, which affect

the available pressure and the ﬂ ow. The location of discharge

and aspiration grilles must be studied carefully to avoid the air

recirculation and the transmission and generation of noises to the

interior.

- Flexible connections must be made between the ducts and the unit

that avoid the noise and vibration transmission.

- No matter the type of ducts type to use, they must not be composed

of materials that propagate ﬁ re nor expel toxic gases in the event of a

ﬁ re. The internal surfaces must be smooth and should not pollute the

air that circulates within them. In any case, the effective legislation

about this issue must be respected.

GESCLIMA PRO electronic control (optional)

CIATpool control is basically composed of a μPC MEDIUM control

board, a pGD1 graphical terminal, a TCO user terminal (optional)

and sensors.

The electronic control GESCLIMA PRO is supplied separte from the

BCP unit in a watertight box (remote control panel).

CIATpool electronic control is required for the free-cooling control

(optional) because electromechanical control cannot manage the

dampers.

Please refer to the brochure of the CAITpool control to obtain more

detailed information about its operation.

When the unit is ﬁ tted with the hot water or electric auxiliary coil, both

optional, they include an electromechanical module for temperature

control: temperature probe and digital controller which acts on the

support element.

Thermostat

Humidistat

Note: in models BCP 70 to 90 with assemblies M00, M01 and M02,

the electric panel is supplied in a watertight box for remote installation

(remote control panel).

Please refer to the brochure of the JuniorBCP E electromechanical

control to obtain more detailed information about its operation.

Condensate drain connection

All models have a condensates drain pan in stainless steel tilted towards

the drain to ensure that no water is trapped

inside it thus preventing health problems. Pan

drain joint, M3/4" in bronze.

Siphon installation norms

- Check that the condensates outlet is not clogged.

- All water drain tubes must be provided with a siphon to avoid bad

smell and water spills.

Perform the assembly as per the scheme of the attached starting

diagram:

Pan in overpressure: It is installed to avoid the access through the

drain tubing of bad smells.

Pan in underpressure:

• Besides the previous application, water must be sucked from the

pan.

• For the correct siphon design, the "A" height must be at least twice

that of the underpressure (mm.a.c) where the condensates pan

is placed.

• The drain tubing must be slightly sloped to ease circulation towards

the drain.

• To control the drain it is advised to insert a funnel in the tubing to

the drain.

Note: The original diameter of the tube must be respected. No

reduction can be made.

Note: Check the connection air tightness.

Checks at fans

- Before commissioning, check the blade rotation direction and that

the axis turns without strokes nor vibrations

- Once running, check the operation conditions: pressures, ﬂ ows and

consumptions.

- The coupling of characteristic curves of the fan and the room is

very important, so that the ﬂ ows and pressures provided to the duct

network are as required.

In order to control the fan rotation

speed the Junior BCP units

(models 20 to 60) have a manual

potentiometer for adjusting the

voltage. This potentiometer enables

adjusting the available pressure

of the unit in accordance with the

installation losses.

Installation hydraulic diagram:

When setting up the hydraulic circuit it is advisable to follow the

recommendations below:

- The direction of water circulation must be observed as indicated on

the unit.

Corrosion behaviour

- The diameters of hidraulic connections can be consulted in the

technical characteristics table (page 4).

- Pipes must be measured with the smaller number of curves to

diminish pressure drops and must be adequately ﬁ tted to avoid force

excessively the exchanger connections.

- Carry out a preliminar control to check that there are not pressure

drops in the installation, before insulating pipes and load the system.

- Avoid the possible transmission of vibrations or efforts of the pipes

to the water exchanger.

- Flexible couplings are recommended for connecting pipework to the

unit , in order to avoid possible transmission of vibrations, breakages

and efforts in the unit or in the pipes. These couplings are compulsory

when the unit is mounted on a frame or on antivibratory supports.

- Provide the accessories necessary on each hydraulic circuit

(expansion vessel, air vents, safety valves, shut-off valves next to

components which need maintenance, etc.).

- Install, or at least anticipate the temporary introduction,

thermomanometers at the inlet and outlet of the unit, to carry out

the installation supervision.

- A water mesh ﬁ lter is compulsory to be placed at the inlet of pool

pump (for particles of Ø > 1 mm), in order to avoid the soiling

of the unit hydraulic circuit. A good maintenance of this ﬁ lter will

avoid corrosion problems in the exchanger, and it will improve the

heat efﬁ ciency of the unit. Not fulﬁ ll this recommendation could make

useless the plates exchanger of the unit.

Important recommendations:

- If the pool water is introduced directly into the unit water condenser,

the addition of chlorine should never be carried out before the inlet

to this condenser.

- These exchangers should never be used in swimming pools with

electrolysis efﬁ ciency treatment. In these cases it is necessary to

install intermediate titanium exchanger, otherwise serious corrosion

problems may occur.

- In the case of a longer standstill, leave the exchanger full of water

pool without ﬂ owing or empty may cause corrosion problems. During

periods of inactivity it is mandatory to ﬁ ll up the hydraulic circuit of

the exchanger completely with demineralised water. To isolate the

hydraulic circuit of the rest of the installation, the installer must have

shut-off valves at the input and output, and a drain for emptying.

 Sulfates and nitrates works as inhibitors for piping corrosion caused by

chlorides in pH neutral environments.

 In general, low pH (below 6) increases corrosion risk and high pH (above

7.5) decreases the corrosion risk.

 Fe3+ and Mn4+ are strong oxidants and may increase the risk for localised

corrosion on stalinless steels.

SiO2 above 150 ppm increase the rink of scaling.

Legend:

+ Good resistance under normal conditions.

0 Corrosion problems may ocurr specially when more factors are value 0.

- Use is not recommended.

The plates exchangers of Junior BCP units (standard in models 70 to

90 and optional in models 40 to 60) are made up of SMO-254 stainless

steel, and the material used for the plates welding is pure copper.

The attached table indicates the behaviour to corrosion for stainless

steel SMO-254 with respect to different compositions of water. Values

outside these ranges may suppose corrosion problems.

10. SAFETY ELEMENTS

High pressure pressostat

Connected to the compressor discharge, it will

stop its operation when the pressure at that point

reaches the setpoint. It disconnects at 29 bar and

it is automatically reactivated.

Low pressure pressostat

When connected to the compressor aspiration, it

will stop its operation when the pressure at that

point goes down below the tare value (caused

by obstructions in the circuit, excessive dirt in the ﬁ lters, fan stop or

ice formation in the evaporator). It disconnects at 0.5 bar and it is

automatically reactivated.

Differential pressostat for clogged ﬁ lters

(optional)

This differential air pressostat connected to the electronic control emits

an alarm signal. This signal indicates that the ﬁ lters have to undergo a

service. Automatic reactivation.

Anti-short-cycle compressor timer

The compressor does not receive the start command until the

established delay elapses as anti-short-cycle from its last shutdown.

Automatic switch in the control circuit

Magnetothermal switch that protects the operation circuit against

continuous surges as well as against high currents of short duration

(short circuits).

Magnetothermals for line protection

They are located at the beginning of the power lines of the compressor

and motorised fans to protect them.

Fan and compressor safeties

Both the fans and the compressor have a thermal protection for the

motor. Its mission is to protect the motor against an excessive heating

caused by a surge.

Main door switch

By using a mechanical device, it impedes access to the electric panel

when the unit is with voltage.

Safety thermostat

This thermostat prevents

the operation of the unit if

the return air temperature

is lower than the set

temperature. Factory value:

24ºC.

Water temperature limit thermostat

In models with water condenser the temperature of the water which

circulates around the exchanger must be checked to ensure that the

water does not circulate at a high temperature which does not guarantee

correct condensation.

This thermostat must be supplied, installed and controlled by the client

which must act on the solenoid valve which closes the ﬂ ow of refrigerant

to the exchanger.

Hot water auxiliary coil

- Characteristics:

• Hot water coils with three-way valves managed by the electronic

control of the unit.

• Assembly inside the unit.

• Polyurethane or copper-copper coating.

• The main technical characteristics of the coils and the diameters of

the hydraulic connections can be referred to in the table on page 4.

- Operation:

• With electromechanical control (standard): The operation of the

temperature thermostat is separate from the humidistat operation.

This will act when there is heat demand.

• CIATpool electronic control (optional): It’s used as support in

heating mode to raise the ambient temperature.

Note: Please refer to the CIATpool control brochure to obtain more

detailed information about the hor water coil operation.

- Coil ﬁ lling:

• The coil ﬁ lling must be made with the purger open until water runs

through it, which is when it is time to close it.

• Cut off the water supply and let the bubbles generated go up to the

highest coil point, which is the same as the purger, and eliminate

by opening the purger.

• Pour more water into the circuit and repeat the previous steps.

• Activate the water pump (to be foreseen by the installer) and

repeat the previous steps until no air noises are heard in the ducts,

which is when the ﬁ lling of the installation will have been ﬁ nished

successfully.

- Possible water freezing must be avoided: glycolling water or by using

anti-freeze thermostat that triggers the 3-way valve.

Note: this thermostat is mandatory in cases in which it uses free-

cooling and works outside at negative temperatures.

11. OPTIONS

Electrical heater

- Characteristics:

• Assembly in a frame in the fan discharge.

• Auxiliary electrical heaters in 1 or 2 stages with built-in control.

• The electrical heater is not compatible with the water coil.

- Operation:

• With electromechanical control (standard): the operation of the

temperature thermostat is separate from the humidistat operation.

The stage(s) will act when there is a demand for heat.

• CIATpool electronic control (optional): the operating mode is

identical to the water auxiliary coil.

Mixing boxes for enthalpic free-cooling

- Characteristics:

• Mixing boxes for free-cooling, with 3 motorised dampers, top intakes

and centrifugal return fan.

• Supplied as an independent module it is connected using a duct

to the Junior BCP unit.

• CIATpool electronic control is required for the free-cooling control

because electromechanical control cannot manage the dampers.

Note: Please refer to the CIATpool control brochure to obtain more

detailed information about the free-cooling operation.

- The direction of the water ﬂ ow must be correct and so the following

indications must be observed:

The change of condenser is done using a manual switching device.

With CIATpool electronic control (optional) this change is automatic

according to the ambient temperature.

The air-cooled unit, essentially comprised of a fan(s) and coil can be

selected with a centrifugal fan as from series ASN and ASM or with an

axial fan as from series ASJ and ASW.

Note: These air-cooled units must include the option of condensation

pressure control.

12. REMOTE CONDENSATION

Air-cooled unit transport

The unit must be handled with care to avoid transport damage. Thus

we recommend:

- For large dimension units, appropriate transports should be used to

reach the installation location.

- For transport in a container, one must be selected that has an easy

load and unload to the installation location.

- Do not dispose of the pallet nor the packaging materials until the

machine is in its ﬁ nal location.

- Transport the units using a forklift truck (all series).

Moreover, in the case of the ASJ and ASW series the units can also

be transported using slings however only by the hoisting points on the

unit. The slings must be separated using a strut to avoid deteriorating

the bodywork.

IMPORTANT: The serial number must be used in all

communication regarding the unit.

Unit identiﬁ cation

All unit bear, legibly and indelibly, a data plate located in a prime space,

with the following data:

Positioning and assembly of the

air-cooled unit

Location designation

Before moving the unit, make sure that all panels are fastened in place.

Lift and lower with care.

When choosing the location, in any way the selected fashion, the

following precautions have to be taken into consideration:

- It is mandatory to comply with norm EN 378-3 on Safety and

Environmental Requirements. Part 3: "In situ" installation and

protection to people.

- It is necessary to check that the structure supports the unit's weigh

(please see weighs in technical characteristics sheet).

- The area where the unit will be located must be perfectly accessible

for cleaning and maintenance operations. Leave enough space so

that air can circulate around the unit (please check minimum free

space for maintenance).

- Foresee appropriate bumping devices in all the installation so that

noise and vibration transmission is avoided.

- For each one of the units, certain installation norms must be followed

as well:

Air-cooled units designed for installation indoors

(ASM and ASN)

All models can be installed on the ﬂ oor or on a brick frame or steel

proﬁ le. To prevent the transmission of vibrations it is recommended

to mount antivibration supports.

• They can also be ﬁ xed to the ceiling using a threaded rod:

- Insert 4 threaded M8 rods in the

framework.

- Insert the rods through the

holes the unit has in its base.

- Place the antivibration mounts,

insert a washer and turn the nuts

until the unit is well secured.

- If there is enough space

between the framework and

the unit, a rubber or neoprene

plate can be squeezed in.

In any case, check that the unit is perfectly level.

Also, in case the installation has an air return which is not ducted,

appropriately-sized grilles must be foreseen in the space formed by

the ceiling, the framework and the walls so that the unit aspires the

return air from the air conditioned spaces.

If it is foreseen that the unit works more on heating than on cooling,

it is preferable to direct it towards the sun.

If little work on heating is foreseen, choose North direction.

- All models can be installed on the ﬂ oor or on a brick frame or steel

proﬁ le.

To prevent the transmission of vibrations it is recommended to

mount antivibration supports.

- Another aspect to be taken into account in the location of the unit will

be the average height of snow in the region.

- Avoid placing obstacles in the air outlet or return. No obstacle may

impede the air aspiration into the coil.

Do not place the coil side in the predominant wind direction.

Anchorage for antivibrators

Air ducts connections (ASN and ASM)

The air aspiration and outlet ducts must be calculated in accordance with

the nominal ﬂ ow and the unit's available pressure (refer to the technical

characteristics table). The duct calculation and design must be made

by qualiﬁ ed technical personnel.

It is advisable to take into consideration the following recommendations:

- Curves in the fan discharge outlet(s) must be avoided. It is

recommendable to have a straight section of duct measuring

approximately 1 metre. If this is not possible, they must be as

smooth as possible, using indoor deﬂ ectors when the duct has large

dimensions.

- When making the ducts, direction sharp changes must be avoided

since they can generate occasional pressure drops, which affect

the available pressure and the ﬂ ow. The location of discharge

and aspiration grilles must be studied carefully to avoid the air

recirculation and the transmission and generation of noises to the

interior.

- Flexible connections must be made between the ducts and the unit

that avoid the noise and vibration transmission.

- No matter the type of ducts type to use, they must not be composed

of materials that propagate ﬁ re nor expel toxic gases in the event of

a ﬁ re. The internal surfaces must be smooth and should not pollute

the air that circulates within them. In any case, the effective legislation

about this issue must be respected.

Fan checks (ASN and ASM)

- Before commissioning, check the blade rotation direction and that

the axis turns without strokes nor vibrations

- Once running, check the operation conditions: pressures, ﬂ ows and

consumptions.

- The coupling of characteristic curves of the fan and the room is

very important, so that the ﬂ ows and pressures provided to the duct

network are as required.

Pulley and belt adjustment (ASM)

The motorised fans on the air-cooled unit ASM are coupled using

pulleys and belts.

In this type of fans, the following must be taken into considerations:

- The pulleys must be on the same plane, so it is important to check

them with the help of a ruler or a laser aligner.

- In case they are not aligned, remove the pulley screws, remove the

pulley and, after removing the hub pin, it can be slided over the axle

(this action can be performed both in the motor as well as in the fan).

- After ﬁ xing the pulleys on the same plane, the belt tension is made

by tightening the tensor screw.

- The belt tension must be checked after 24 hours of motor operation.

Pulleys must stay on the same plane

Cooling connections

Once the Junior BCP units and the air-cooled unit are positioned, the

cooling links must be laid between them.

In the case of the air-cooled units ASM and ASW

it is recommended to place a siphon in the gas line

every 3 metres of shoulder to ease the oil return

to the compressor.

For determining the equivalent length, the pressure drops

in accessories must be taken into account.

Tube installation norms must be

respected and inspect carefully the

tube lay out, looking for the shortest

distance and the lowest possible

number of curves. Also, chokes must

be avoided, using large curve radii

(the curve radius must be  3.5 x  ).

- Align precisely both parts of the connection (unit and tubes). There

is no error risk when both tubes have different diameters.

- Run a pressure test in the cooling tubes and a search for leaks to

verify the cooling installation.

- Create a vacuum in the installation to eliminate humidity inside the

circuit.

- Charge the unit with gas as per the data stated in the technical

characteristic table. If the equivalent length

of the cooling lines is over 6 m, an additional

charge will be needed per meter as per the

following table.

Connection of the unit to the cooling lines

For the refrigerant lines, use only cooling type seamless tubes. Under

no circumstance use sanitary type cooper pipe.

Following these steps is recommended:

- Revise and clean the tube ends to eliminate the burs from cutting

them and any other impurity that could have deposited inside or on

the outer surface. How clean the tubes are will dictate the degree or

airtightness. Also, we will avoid the dirt formation that may collapse

some spots in the cooling circuit.

- Apply isolator to the tubes, covering them and afﬁ x it with tape. The

material used must guarantee air tightness at operating pressure

and temperature.

- Remove the plugs that protect the cooling connections of the unit

precisely at the moment of connecting the tubes.

Note: Check the undercooling of the ﬂ uid when ﬁ lling out the "operation

veriﬁ cation sheets" to make sure the charge is correct.

- Check that all the electric, hydraulic and air duct connections are in

good condition and perfectly connected.

- In the case of remote condensation also check the cooling

connections.

- Once the above veriﬁ cations have been carried out, the control circuit

is supplied with voltage by the automatic control switch. It is necessary

to leave the compressor crankcase heater with voltage for 24 hours

before starting the compressor.

- Check the safety elements. If any safety device is active the fault

must be located and the device reset.

- Check the values selected for the humidity and temperature setpoints

(optional) on the control command panel. Factory values: 80% RH

and 20ºC.

- With the CIATpool electronic control (optional) the differential

established between the air and water temperatures must also be

checked . The air temperature must be 2 or 3ºC higher than the water

temperature in order to avoid condensation on the walls and windows

inside the premises.

- Check the position of the manually adjusted bypass damper adjusting

the opening percentage according to the installation requirements.

- Check the response of the motorised free-cooling dampers (optional).

- The doors and windows must be closed in order to facilitate the air

and water temperature rise. The free-cooling dampers (optional)

must be ﬁ tted in the minimum opening position..

- Check the operation of the unit and verify that the current absorbed

by each motor of the unit is as intended.

- All the models have a scroll compressor ﬁ tted. Verify that they turn

in the correct direction and, if not, reverse the power wires.

CHECK SENSE OF ROTATION

- When starting the compressor, if the

refrigerant charge has not been completed

and is lower than that required, the aspiration

pressure will be considerably lower than

normal. The low pressure pressostat connected to the compressor

aspiration will stop operating when the pressure at this point

drops below the tare value (disconnecting at 0.5 bar and resetting

automatically). Ensure the absence of any refrigerant leaks or the

presence of air in the circuit

- Take temperature measurements of the liquid line and aspiration

line as well as the outlet and aspiration pressure. Check that the

undercooling and overheating values are within the permitted limits.

To adjust the refrigerant charge, a schrader valve is available on the

liquid line.

- Check that the electrical power supply matches the unit voltage and

that its value lies within acceptable limits.

- Proceed to ﬁ ll the hydraulic circuit (in models with water condenser):

• Open the water circuit valves and ensure that the water circulates

around the exchanger with the pump in service.

• Bleed the air in the hydraulic circuit.

• Check the operation of the water ﬂ ow switch and of the water

circulation pump.
