Hydraulic and chilling circuit components (Fig.2):

1. One-way valves (only IP units), make the

refrigerant obligatorily pass through the appro-

priate heat exchangers, depending on the

operating cycle.

2. Low pressure switch, with fixed setting. It is

installed on the suction pipe and blocks the

compressor if the operating pressures drop

below the tolerated values. It automatically

resets as the pressure increases. If it activates

frequently, the unit will block and can only be

restarted by resetting via the user interface

terminal.

3. High pressure switch, with fixed setting. It is

installed on the delivery pipe and blocks the

compressor if the operating pressures exceed

the tolerated values. If it activates, the unit will

block and can only be restarted by resetting

via the user interface terminal.

4. Thermostatic valve, of the type with external

equalizer.

Used as both a heat pump and chiller, it’s task

is to supply the evaporator correctly, keeping

the selected degree of superheat at a steady

level.

5. Dehydrator filter of the mechanical type. Retains impurities and traces of moisture in the circuit.

6. Differential water pressure switch. This is standard supply and is installed on the connections between the exchanger’s

water inlet and outlet. If it activates frequently, the unit will block and can only be restarted by resetting via the user interface

terminal.

7. 4-way cycle reversing valve (IP units only). Reverses the direction in which the refrigerant flows when the summer/winter

operating modes change.

8. Fluid receiver (IP units only). This is a plenum tank that accounts for the refrigerant charge variations required by the machi-

ne as the summer/winter operating modes change.

Pumping and Storage module

The purpose of the storage and pumping module is to lower the number of compressor surges, increasing the amount of water

in the system and, thus, its thermal inertia. It can be coupled to the side of the chiller and has the same depth and height dimen-

sions. Available in the Standard versions for all models and in the High Head version for models 16-19-24-30. In nominal ope-

rating conditions in the cooling mode, the Standard Version is able to provide the circulating water with 40 to 102 kPa residual

head, while the High Head Version has 123 to 142 kPa residual head.

With reference to the figure alongside and depending on the model, the Storage and

Pumping Module is equipped with:

1A. Multiple stage pump. With a high head, able to suit the majority of installation requi-

rements. All pump components that come into contact with the pumped fluid are made

of stainless steel.

1B. Circulation pump. Three-speed circulation pump that provides the chiller with the

right water flow rate. The 3rd speed is set during the production phase: it is inadvisa-

ble to modify this speed as the operation of the Module would be impaired.

2A. Pump suction sleeve (1” GAS female) used for returning from the system.

2B. Returning stub pipe from the system (1” GAS male) used for returning from the

system.

3. Pressure gauge. Indicates the pressure level in the storage tank (only for mod. 30-

33 in the High head version and mod. 50 in the Standard version).

4. Delivery stub pipe of the system (1” GAS male).

5. Safety valve. With fixed setting. Activates when the pressure in the tank exceeds the

preset values.

6. Drain cock. Drains the water from the storage module to prevent it from freezing during

winter periods, if not used for hot water storage.

7. Electric antifreeze heating element connection (Accessory). Allows the storage

tank’s electric antifreeze heating element to be installed.

8. Storage tank.Reduces the number of compressor start-ups and fluctuations in the

temperature of the water conveyed to the users. It is insulated with polyurethane foam

to prevent the formation of condensation and heat exchanges towards the outside.

9A. Automatic air venting. Vents the tank when the system is filled.

9B. Air venting. Positioned on the highest part of the module’s wet pipes, it bleeds the

air from the module itself when the system is filled.

10. Metal gauze water filter. Can be inspected. Installed on the pump/circulator intake.

Preventing machining residues (dust, swarf) in the water pipes from entering the

pump or plate-type heat exchanger.

11. Surge chamber. This is a closed, diaphragm type chamber. It absorbs the variations

in the volumes of water in the system caused by temperature variations.

12. Metal structure. Made of galvanized sheet metal panels coated with polyurethane

powder paint to ensure good protection against adverse weather conditions.

GP - Protective Grilles

The kit comprises two electrowelded, painted grilles to protect the coils with extended sur-

faces.

ST - Bracketing kit for the Unit + Pumping and Storage module

The bracket kit comprises four bent sheet metal elements assembled together by self-

threading screws. The distance between the holes allows the pre-fixed chiller and storage

module to be recriprocally fastened together. Equipped with 8 rubber supports that redu-

ce the extent to which the units transmit vibrations to the bearing points. The brackets

have holes so that they can be fixed to the floor or to shelving. They are supplied painted

the same colour as the unit and storage module.

AVG - Rubber vibration dampers.

Kit comprising 4 cylindrical vibration dampers made of vulcanized rubber on metal washers.

They reduce the mechanical vibrations transmitted by the compressor and fan/s to the bearing

surface of the machine during normal operation. They can be used/installed under the unit (4

pcs), under the Storage Module (4 pcs) or under the Bracketing Kit (8 pcs).

KT - Flexible wet connections.

Allow the components to be quickly installed, even when the connections are slightly misa-

ligned, also limiting the extent to which vibrations are transmitted from the chiller to the sto-

rage tank and, consequently, to the system.

AV - Hydraulic quick couplings

Used for the wet connections between the Unit and Storage module, making the unit + module assembly as compact and small

in size as possible. The kit consists of two couplings complete with seal and two threaded stub pipes with relative groove.

NOTE: If the hydraulic quick couplings are not used, refer to the coupling measurements given in the tables.

The kit consists of two couplings complete with seal and two threaded stub pipes with relative groove.

This device allows all the control and monitoring functions of the control unit on the machine to be controlled up to 100 meters

away from the actual machine itself. Use a three-pole or three-wired section cable in PVC type N07-VK with a 1 mm2wire sec-

tion for the connections. The transmission line must be routed in a dedicated duct, separate from any electric powering lines

(230/400 V).

The remote control has the following keys:

1 - MODE key : selects the operating mode

2 - ON/OFF key : turns the unit ON/OFF and resets the alarms

3 - Mode + ON/OFF keys : used to access and quit the various menu levels

4 - UP key : scrolls forwards through the menu items or increases the value of a parameter

5 - DOWN key : scrolls backwards through the menu items or decreases the value of a para-

meter

RAG: Antifreeze heater Storage Tank (accessory used in conjunction with the Storage

and Pumping Module)

Glow plug type; maintains the water in the storage tank at a temperature able to prevent ice from forming during winter stand-

stills. (250W/230V-1/50Hz).

OP - Programmer Clock

This is a device (housed in a modular casing 45 mm in width) that allows the unit to be turned on and off (without needing to be

regulated) by means of the remote controlled digital on-off input on the control board of the unit. Up to 14 settings can be ente-

red, divided as required throughout the 7 days of the week. The clock is connected to the machine with 4 wires of the PVC N07-

VK type with a 1.5 mm2 section. Take care to route the cable since the wires are live (230V mains voltage).

Minimum space required for operation

To correctly install the unit, comply with the measurements for the free area that must

be left around the machine, as shown in the figure.

This will ensure good air circulation, allow the unit to operate correctly and facilitate

future maintenance work.

Allow a distance of at least 3/4 of the height of the actual machine when installing shel-

ters over this latter.

NOTE: The unit must not be surrounded by more than three walls as this would

impede the ventilation required for it to operate properly.

The distances must be doubled if the unit is to be installed in a pit.

as an accessory

-Remote On/Off CONNECTION

Remove the jumper of terminals 3-4 for the REMOTE ON/OFF command and connect the required electrical contact.

-REMOTE SUMMER/WINTER connection

Remove the jumper of terminals 1-2 for the REMOTE SUMMER/WINTER command and connect the required electrical con-

tact.

The parameter for enabling the instrument on the machine and/or the remote control is (par. H27), while for the ON/OFF and

S/W remote controls it is (par. H27=1)

Proceed in the following way to access parameter H27 and make the required configuration:

1. Press the ON/OFF key and keep it depressed until the instrument comes on.

2. Press the MODE and ON/OFF keys at the same time for one second. The word Set will appear.

3. Repeatedly press the MODE key until Par appears.

4. Press the MODE and ON/OFF keys at the same time and keep them depressed for at least one second until Cnf appears.

5. Press the MODE and ON/OFF keys at the same time and keep them depressed for at least one second until H01 appears.

6. Using the MODE key, select parameter H27 and configure it as needed.

7. After having modified the parameter, repeatedly press MODE and ON/OFF until the initial mask returns.

Turn the unit off and on again with the main switch so as to reset the controller.

The machine is now ready to operate.

Wiring diagrams

The general wiring diaframs of the units are given on the following pages. These diagrams show the connections required for

powering the machine, activation of any supplementary loads (pump, electric heating element and the alarm indicator), con-

nection with the available digital inputs (ON/OFF, change of season summer/winter and connection with the remote control

panel).

All the connections must be made in compliance with the GENERAL REGULATIONS listed above.

ELECTRICAL CONNECTIONS

Electrical connections

ALL THE ELECTRICAL CONNECTIONS MUST BE MADE BY QUALIFIED PERSONNEL IN THE ABSENCE OF ELECTRIC

POWER. CONSULT THE “GENERAL SPECIFICATIONS” SECTION FOR THE ELECTRICAL SPECIFICATIONS OF THE

UNITS.

A- UNIT

- Electric power line

The machine’s power line should be routed in compliance with the current standards governing the classification of the places

in which they are installed. The machine’s power line should follow a precise route so that it is as short as possible and unbro-

ken. Proceed in the following way in order to carry out this operation:

-open the front panel of the unit.

-Route the powering line inside the unit (Fig. 1-A) through one of the holes in its structure (Fig. 1-B).

-Allow the line to pass into the compressor housing until it reaches the switch

(Fig.1-C). Remove the protective cover (Fig. 1-D) to access the switch.

Additional connections to make in the installation site

The electric panel is fitted with additional terminal boards for use if accessories controlled directly by the controller must be

installed.

The following table lists the codes and meanings of the various terminals, along with their respective functions and characteri-

stics:

-Connect the conductors straight to the switch.

-Fix the power cable in place with a clamp (Fig. 1-E).

-Fix the protection conductor (ground wire) to the

grounding block (Fig. 1-F).

- Powering system

Single-phase units must be powered with 3 conduc-

tors (phase-neutral-ground).

Threephase units must be powered with 5 conduc-

tors (phase 1-phase 2-phase 3-neutral-ground).

The power cables of the machine’s power supply line

must therefore be off-taken from a threephase symme-

tric system equipped with neutral conductor and sepa-

rate protection conductor.

- Protection on the supply side

An automatic switch must be installed on the supply

side of the above mentioned line in order to protect

against any overcurrents and indirect contacts which

could occur as the machine operates..

It is advisable to install an automatic limiter switch (IL) with the minimum specifications given in tables 1 and 2.

Connections between the line and switch must be made in compliance with the current laws governing electrical safety mat-

ters, regarding the type of installation and environmental conditions in which the machine is installed.

- Protection conductor (ground wire)

The protection conductor from the electricity main must be connected straight to the ground screw, able to guarantee the equi-

potential connection of all metal grounding points and structural parts of the machine (Fig. 1-F).

- Neutral conductor

The neutral conductor that forms the line must be connected to the neutral terminal marked “N”, corresponding to the fourth

pin of the panel’s main disconnector.

B-STORAGE AND PUMPING MODULE

Depending on the model, the Storage and Pumping Module can be equipped with either a circulator or multiple-stage pump,

both complete with power cable.

All the electrical components in the Module (circulator/pump and electric antifreeze heating element if installed) must be con-

nected straight to the terminal board in the relative unit.

Proceed in the following way to make the connections:

-Route the pump cable through the partition on the connection side of the chiller using the core hitches that pass through this latter.

-Access the chiller through one of the core hitches in the connection side, connect the pump cable to the terminal board and fix

it in place with the cable clamp on the electric panel.

-Make the connections as shown in the following diagrams.
