Introduction

The AQUACIAT 2 water chillers, whether cooling only series

LD, LDC, LDH or reversible series ILD, ILDC, ILDH , make it

possible to meet the air conditioning and heating requirements

of public and office buildings while also catering for the needs

of industrial processes.

The AQUACIAT 2 LD, ILD units are air condensation liquid

chillers which guarantee reliable, secure operation in the area

for which they have been designed.

All equipment is tested and checked in the factory. All the

equipment is delivered with the full refrigerant load.

The units comply with the standards EN 60-204 - EN 378-2 as

well as with the following directives:

- machines 98/37 EC

- EMC 2004/108/CE

- PED 97/23 EC

-> category 2 (LD-LDC-LDH-ILD-ILDC-ILDH)

All persons responsible for installing units, commissioning

them, operating or maintaining them must be familiar with the

instructions contained in this manual as well as with the

technical characteristics specific to the installation site.

Reception of the unit

Each unit has a type plate indicating the unit’s identification

number. Please check the unit’s type plate to make sure you

have received the correct model. The identification number

must be specified in any correspondence.

When you receive the unit, please check it for any damage. If

you detect any damage or if the delivery is incomplete, please

enter the usual reservations on the delivery note and confirm

these to the transporter by recorded delivery letter within three

days of reception.

The maximum storage temperature is 50°C.

Guarantee

The guarantee period is twelve months as of the date of first

use provided that this date is within three months of the invoice

date.

It is 15 months starting from the invoice date in all other cases.

NOTE: for more information, please see our general sales

conditions.

Safety instructions

In order to avoid any risk of accident during installation, start-

up or adjustment, it is essential to pay attention to the specific

characteristics of the equipment, such as:

- Pressurised refrigerant lines

- Presence of refrigerant fluid

- Presence of electrical voltage

Only experienced, qualified personnel are authorised to handle

such equipment.

It is essential to respect the recommendations and instructions

present in this manual and the various diagrams supplied with

the unit.

Since the units contain pressurised equipment and

components, we recommend that you consult your

professional association for details of the regulations

applicable to you as operator or owner of the said pressurised

equipment or components. The characteristics of this

equipment can be found on the type plates or in the regulatory

documentation supplied with the product.

The units are equipped with a fire protection device as

standard.

IMPORTANT: before performing any operation at the unit,

make sure that the power supply has been disconnected at the

general isolator located on the unit’s electrical panel.

Location of the unit

The standard use of these units is for refrigeration and there is

therefore no requirement for resistance to seismic activity.

Resistance to seismic activity has not therefore been tested.

Before installing the unit, the installer should verify the following

points:

- The unit must be installed outdoors

- The surface of the structure must be strong enough to support

the weight of the unit.

- The unit must be perfectly level.

- Sufficient space must be left around and above the unit to

permit service and maintenance operations (see the

dimensional diagram supplied with the unit).

- The location must comply with the regulation EN 378-3 and

any other specifications applicable to the installation site.

- The selected location must not be liable to flooding.

- Position the unit above the average snow height in the region

in which the unit is to be installed.

In the case of the reversible units, i.e. ILD, ILDC, ILDH, provide

drainage for defrosting water and provide for the possibility of it

freezing on the ground.

- It is highly recommended to install anti-vibration mounts

between the unit’s support and frame as well as flexible

couplings on the hydraulic piping in order to reduce structure-

borne vibrations (see section on Vibration isolation).

- Sound level: our units have been designed to ensure

operation at low sound levels with this type of equipment.

However, it is important when designing the installation to take

account of the external environment with regard to noise

emissions as well the type of building with regard to airborne

and structure-borne sound (vibrations).

Conduct a study with an acoustic engineer.

Important: The ambient temperature must not exceed 50°C

during the unit stoppage cycles.

Handling and positioning

To lift the unit, fix the slings to the handling holes provided for

this purpose.

The dimensional diagram supplied with the unit indicates the

coordinates of the centre of gravity and the position of the

anchor points.

However, the unit can be handled using a fork-lift truck

provided that the necessary precautions are taken to prevent it

from slipping on the forks of the truck.

Attention:

If a fork-lift truck is used, follow the instructions listed on the

labels on the units. Failure to do so may create a tipping hazard

and result in physical injury.

- Fix the slings only to the anchor points provided and indicated

on the unit.

- Use slings of a suitable capacity and follow the lifting

instructions on the diagrams supplied with the unit.

- Attention, the centre of gravity is not always located in the

middle of the unit and the strains applied to the slings are not

always identical.

- Lift and position the unit carefully and take care not to tilt it

(max. angle of tilt: 15°) since this could impair its functioning.

- Use textile slings with shackles to avoid damaging the

housing.

- Use a frame designed to adjust the centre of gravity when

removing the slings from the top of the unit.

- Never subject the unit’s metal parts (panels, stanchions, front

access doors) to handling strains. Only the frame is designed

for this.

- Safety of handling is ensured only if all these instructions are

respected. Failure to observe these instructions may result in

damage to the equipment and accidents to personnel.

This diagram is provided only as a general

guide. In all cases, it is necessary to refer to

the diagrams affixed to the unit as well as

the documentation supplied with the unit.

Hydraulic connection

The hydraulic connection must be established in accordance

with the diagram supplied with the unit which indicates the

positions and dimensions of the water inlets and outlets at the

exchangers.

The following points must be observed during connection:

- Respect the water inlet and outlet connection directions

indicated on the unit.

- A dimensioning study must be performed in order to respect

the operating conditions (flows and pressure drops). The

diameter of the piping may therefore be different from that

envisaged at the exchanger.

- The piping must not transmit any axial or radial stress or any

vibration to the exchangers.

- The water must be analysed and treated if necessary (you are

recommended to consult a specialist qualified in water

treatment). This analysis will reveal whether the water is

compatible with the various materials with which it comes into

contact in the unit and make it possible to avoid any electrolytic

couple phenomena.

- Pipes 99.9% copper with copper and silver brazing

- Threaded bronze couplings or flat steel flanges depending on

the model of the unit.

- Plate heat exchangers and connections in AISI 316 - 1.4401

stainless steel with copper and silver brazing

- The water circuit should have as few bends and horizontal

sections at different levels as possible.

- Install the stop valves close to the water inlets and outlets in

order to isolate the exchangers.

- Install the manual or automatic air bleeds at the high points of

the circuit(s).

- The manual or automatic air vents mounted on the machine

are not intended to bleed the rest of the hydraulic circuit.

(I)LDC - (I)LDH - Whether or not the machine and pump are

stopped or operating, make sure that a pressure of one bar is

always available at the suction side of the pump.

- Install the drainage connectors at all the low points of the

circuit(s).

- Insulate the cold pipes (after testing to ensure they are

watertight) in order to reduce heat loss, to prevent condensates

and to avoid damage due to frost.

- Install heating resistors on all channels liable to be exposed

to frost.

- The mechanisms necessary for filling and draining the heat

transfer fluid must be provided by the installer.

- To ensure that the pressure of the heat transfer circuit

remains lower than the intended working pressure, do not

introduce any static or dynamic pressure into the circuit.

IMPORTANT: To prevent any risk of fouling or damage to the

plate exchangers, it is essential to install a screen filter at the

water inlet. This should be as close as possible to the

exchanger and in a location which can be easily accessed for

disassembly and cleaning. The meshing of this filter will be no

greater than 600 µm (see option in price list)

IMPORTANT: It is essential to use flexible connectors on

hydraulic pipes.

IMPORTANT: The use of untreated or inadequately treated

water may result in scaling or deposits of algae or mud or may

lead to corrosion or erosion. CIAT cannot be held responsible

for any damage resulting from the use of untreated or

inadequately treated water or saline or brackish water.

NOTE: the maximum working pressure on the water side is 10

bars for LD-ILD and 4 bars for LDC-LDH-ILDC-ILDH.

- The water flow detector is supplied mounted in the unit.

If the hydraulic circuit has to be drained for a period longer

than a month then it is necessary to fill the entire circuit

with nitrogen in order to avoid any risk of corrosion.

IMPORTANT: If the circuit is not protected by an antifreeze

solution and the unit does not run during periods of frost then

it is obligatory to drain the evaporator and the external piping.

● The units have been designed to comply with European

standard EN 60204-1.

● They comply with the machinery and EMC directives.

● All cabling must be undertaken in compliance with the

regulations applicable at the installation site (in France,

NF C 15100).

● In all cases, you should refer to the wiring diagram supplied

with the unit.

● Respect the power supply characteristics indicated on the

type plate.

Principal components of the

refrigerant circuit

Compressors

The units LD-LDC-LDH-ILD-ILDC-ILDH use hermetic SCROLL

compressors.

Oil

The compressors contain a polyester oil (POE) Copeland

3MAF (32 cSt) in the case of R410A units. If necessary, oil can

be topped up using ICI Emkarate RL 32 CF or Mobil EAL Arctic

22 CC if the 3MAF product is not available in the case of

R410A units.

Refrigerant fluid

Units of size 80 to 1100 run with R410A.

Exchangers

The evaporators are single circuit, brazed plate exchangers.

The evaporators are equipped with polyurethane foam heat

insulation of thickness 10 mm.

The heat transfer fluid must be filtered and internal inspections

must be conducted.

All repairs or modifications to the plate exchangers are

prohibited. Exchangers may only be replaced by an original

part fitted by a qualified engineer. The replacement of the

exchanger must be recorded in the maintenance log.

Thermostatic expansion valve

All units are equipped with a thermostatic expansion valve with

a hermetic monoblock design and factory set to maintain an

excess temperature of 5 to 7°C under all operating conditions.

Dryer

All the units are equipped as standard with a filter dryer which

has the task of keeping the refrigerant circuit clean and free of

humidity. The dryers consist of a molecular filter which allows

them to neutralise any acids which may be located in the

refrigerant circuit.

Liquid sight glass

The liquid sight glass, which is located after the dryer in the

liquid line, makes it possible to monitor both the charge at the

unit and the presence of humidity in the circuit. The presence

of bubbles in the sight glass indicates that the refrigerant fluid

charge is inadequate or that non-condensing products are

present in the refrigerant circuit.

Safety regulation and equipment

Electronic regulation and signalling module

All the units in the AQUACIAT range are equipped with a

CONNECT electronic regulation and signalling module based

on a microprocessor.

This electronic module controls the operation of the

compressors.Thus, depending on the cold (or hot) water return

temperature compared to the setpoint, the electronic module

may initiate the stepped start-up or shut-down of the

compressors.

Main functions

● Regulation of the water temperature:

- chilled water (series LD-LDC-LDH)

- chilled water and hot water (series ILD-ILDC-ILDH)

● Three types of regulation are possible:

- Difference on water return.

- PIDT at water outlet.

- Regulation as a function of the external temperature

● In the standard configuration, the units are designed for

regulation on the chilled water return. To obtain PIDT regulation

on the water outlet temperature, refer to the Connect regulation

instructions.

● Control of the operating parameters.

● Fault diagnosis.

● Storage of faults in memory in the event of power failure.

● Management and automatic equalisation of compressor

operating times (multi-compressor systems).

● Remote control possibility (start/stop, modification of

setpoint temperature, operating states, general fault) using a

remote control unit (OPTION).

● Possibility of remote reporting of operating states and faults

via an interface module (OPTION).

FOR A DETAILED DESCRIPTION OF ALL THESE

FUNCTIONS PLEASE REFER TO THE CONNECT

PRACTICAL GUIDE (NO2 27).

Handling of safety devices

All the unit’s safety devices are managed by the regulator’s

electronics card. If a safety device triggers and shuts down the

unit, it is necessary to locate the fault, reset the safety device if

required and then acknowledge the defect by pressing the

“RESET” button on the display card.

The unit then restarts when the minimum time imposed by the

anti-short circuit mechanism has elapsed.

For information on the adjustment values of the various safety

devices and the procedure for the acknowledgement of the

various faults, consult the instructions for the CONNECT

regulator.

Low pressure control

Every unit is equipped as standard with a LP sensor for each

hydraulic circuit. This sensor allows users to view the LP value

and also enables the electronics module to perform its safety

function by not permitting the LP value to fall below the fault

threshold parameterized in the regulator.

High pressure control

● Manual high-pressure pressostat.

Each refrigerant circuit is equipped with a HP pressostat which

fulfils a safety function. Thus, when the HP value rises above

the value that has been preset in the pressostat, the power

supply to the relevant compressor(s) in the refrigerant circuit is

cut and the fault is indicated by an LED on the regulator’s

control panel.

The HP pressostats have to be reset manually. The fault is

therefore acknowledged when you reset the pressostat by

pressing the RESET button on the control panel.

Note: some units possess two pressostats per circuit

(electrically connected in series).

● High-pressure sensor

Every unit is equipped as standard with a HP sensor for each

refrigerant circuit. This sensor allows the user to view the HP

value and enables the electronics module to perform both a

unit regulation function by acting on the fans, and a safety

function.

Evaporator antifreeze protection

The evaporator is protected against freezing by two sensors:

● Evaporator chilled water outlet sensor

Each evaporator is equipped with an antifreeze sensor (located

at the chilled water outlet) which monitors the temperature of

the fluid that is to be cooled. If this falls below the value that has

been set in the regulator, the power supply to the relevant

compressor(s) in the refrigerant circuit is cut and the fault is

indicated by an LED on the regulator’s control panel.

This sensor performs a safety function and must not therefore

be replaced by the customer.

● Freon sensor at evaporator inlet

This sensor monitors the temperature of the refrigerant at the

evaporator inlet. If this falls below the value that has been set

in the regulator, the power supply to the relevant compressor(s)

in the refrigerant circuit is cut and the fault is indicated by an

LED on the regulator’s control panel.

● LP sensor

The LP sensor and the exchanger water outlet sensor perform

permanent monitoring to avoid the breakage of the

exchangers. If the values of these two sensors become too

divergent, the circuit in question shuts down and the fault is

indicated by a message and the illumination of a red LED at the

control panel.

Evaporator water circulation controller

Every unit possesses a water circulation control mechanism

fitted as standard. Thus, if the water flow is insufficient, the

power supply to the compressor(s) is cut and an LED indicates

the dault at the regulator’s control panel.

Internal compressor protection

All the models in the AQUACIAT 2 range are protected against

overheating of the electric motor and excessive outlet

temperatures.

A phase controller may be added at the customer’s request

(OPTION)

Outlet sensor

Every unit is equipped as standard with an outlet sensor for

each refrigerant circuit. This sensor, which is located on the

discharge pipe allows the user to view the value of the outlet

temperature and enables the electronics module to fulfil its

safety function.

Thus, when the outlet temperature value rises above the

maximum temperature threshold that has been parameterized

in the regulator, the power supply to the relevant compressor(s)

in the relevant refrigerant circuit is cut and the fault is indicated

by an LED on the regulator’s control panel.

Fire protection

Every refrigerant circuit in the units contains a mechanism to

protect against the risk of overpressure due to a fire (fusible

plug or valve blockage).

Phase controller kit (OPTION)

The phase controller kit makes it possible to perform the

following functions:

- monitor the direction of rotation of the phases

- detect the total absence of one or more phases

- monitor overvoltages or undervoltages

This kit consists of:

- the network controller relay + rail and fixing screws

- connecting cables

- assembly instructions

Commissioning

Pre-commissioning checks

Never commission a machine without first having read the

manual in full.

National regulations must be respected during the testing of

the installation.

Before starting the unit, perform the following checks:

- Compare the entire installation with the refrigerant and

electrical diagrams.

- Check that all the components comply with the specifications

in the diagrams.

- Check that all the documentation and safety equipment

required by applicable European standards is present.

- Check that the access and emergency routes are

unobstructed.

- Check the assembly of the connectors.

- Check the quality of the welding and seals and make sure

there is no leakage of refrigerant fluid.

- Check the direction of rotation of the fans

- Check the protection against mechanical damage.

- Examine any noise emission problems specific to the

installation.

- After opening the water circuit valves, make sure that the

water circulates in the chiller when the pump is operating.

- Bleed the air from the hydraulic circuit.

- Check the operation of the circulation controller

- Check that the fixing collars have been tightened correctly on

all the piping

- Check that all the electrical connections are tightened

correctly

- Leave the crankcase heaters of the compressors powered for

6 hours before operating the compressor (Except LD - LDC -

LDH 80 90)

Touch the crankcases to make sure that the heaters have been

functioning correctly (they should be warm).

- Check that current is arriving at the general connection and

make sure that the supply voltage is within the permitted limits

(-10% to +6% compared to the rated voltage).

Start up

- The unit must be switched on and started up by a qualified

engineer.

- Start-up and operating tests must be performed with a

thermal load and water circulation in the exchangers.

- Apply power to the main board.

- Make sure that the machine is configured for local control

(selected at regulator)

- Use the button to select the operating mode (operation

as chilled water or hot water unit).

- Adjust the chilled water and hot water setpoints.

- Press the on/off button to start the unit .

- The internal safety devices are active. If a safety device

triggers, locate the fault, reset the safety device if necessary

and press the RESET button at the control panel to

acknowledge the fault.

- The unit cannot be started up for a period of 2 minutes (time

required for all the safety devices to be identified and

registered). The control stages are activated in series as a

function of demand.

To shut down the unit other than in emergency situations,

it is necessary to use:

– either the On/Off switch at the control panel

– or a potential-free contact at the automaticity control.

Do not use the master switch because the electrical panel

must continue to be powered (antifreeze protection,

crankcase heater).

NOTE:

AQUACIAT models are machines which operate with R410A; it

is essential for engineers to use equipment which is compatible

with R410A which has a working pressure approximately 1.5

times greater than machines operating with R22 or R407C.

Essential points to be checked

- Make sure that each compressor is rotating in the right

direction by checking that the outlet temperature rises quickly,

that the HP increases and that the LP falls. If the direction of

rotation is incorrect, this is due to the incorrect cabling of the

electrical power supply (phase reversal). To obtain the correct

direction of rotation, reverse the two power supply phases.

- Check the outlet temperature of the compressor(s) using a

contact sensor

- Make sure that the absorbed current is normal

- Check the functioning of all the safety devices

Adjustment of the water flow

Since the overall pressure loss of the installation is not known

precisely at the time of commissioning, it is necessary to adjust

the water flow with the adjusting valve in order to obtain the

desired nominal flow.

In effect, because of the pressure loss it generates in the

hydraulic network, this adjusting valve makes it possible to lock

the pressure/network flow curve to the pressure/pump output

curve and thus obtain the nominal flow corresponding to the

desired operating level.

The value read for the pressure loss in the plate exchanger

(obtained using the pressure gauge connected to the

exchanger’s input and output) is then used to monitor and

regulate the installation’s nominal flow.

Respect the procedure described below:

- Fully open the adjusting valve

- Allow the pump to run for 2 hours in order to eliminate any

solid particles which may be present in the circuit

- Record the pressure loss at the plate exchanger on pump

start-up and 2 hours afterwards

- If the pressure loss drops, this means that the screen filter is

clogged. It is necessary to dismount and clean it.

- Continue the process until the filter is no longer clogged

- Once the circuit has been cleared of contaminants, measure

the pressure loss at the plate exchanger and compare it to the

theoretical pressure loss of the selection.

If the pressure loss is greater than the theoretical loss then the

flow is too great. The pump output is therefore too high given

the pressure loss in the installation. In this case, close the

adjusting valve one turn and read the new pressure loss.

Repeat the operation and close the valve each time until the

nominal flow is obtained at the desired operating point.

In contrast, if the pressure loss in the network is too high

compared to the available static pressure supplied by the

pump, the resulting water flow will be reduced and the

temperature difference between the exchanger’s inlet and

outlet will increase, thus making it necessary to minimise the

pressure losses.

Checking the refrigerant fluid load

The units are shipped with a precise refrigerant fluid load.

To make sure that the refrigerant fluid load is correct, perform

the following checks with the unit operating at full capacity:

- check that no gas bubbles appear in the liquid sight glass

- check the real sub-cooling value at the condenser outlet. This

should be between 5 and 8°C depending on the type of unit.

Measurement in air conditioning operation for ILD units

If there is a significant volume of fluid missing, large bubbles

can be seen in the sight glass liquid, the suction pressure falls

and there is a high level of overheating at the compressor

intakes. After the leak has been detected and the machine’s

refrigerant load has been completely drained using a recovery

unit, the machine must be refilled. Perform the necessary

repairs, test for watertightness while making sure that the

maximum working pressure at the low pressure side is not

exceeded and refill the unit.

Refilling must be performed in liquid phase at the liquid valve.

The quantity of refrigerant fluid introduced into each circuit in

the unit must correspond to the values indicated on the type

plate.

The same operations should be performed if the sub-cooling

value is less than the specified values.

NOTE: When the unit is started, an excessively low suction

pressure or excessively high condensing pressure may be

observed. There are various possible causes for these

problems - see the section Analysis of operating anomalies.

If the operating mode is inverted

To optimise the operation of the unit, it is essential to:

- adjust the refrigerant load.

- optimise the adjustment of the expansion valve.

- adjust the safety parameters of the regulator to correspond to

the operating mode.
