- The appliance must be installed in accordance with the laws in force in the country in which the unit is installed.
- Unauthorized tampering with the electrical and mechanical equipment will VOID THE WARRANTY.
- Check the electrical specifications on the identification plate before making the electrical connections. Read the
instructions in the specific section where the electrical connections are described.
- If the unit must be repaired for any reason, this must only be done by a specialized assistance center recognized
by the manufacturer and using genuine spare parts.
- The manufacturer also declines all liability for any damage to persons or property deriving from failure of the information in this manual to correspond.
- Proper uses: this series of chillers is designed to produce cold or hot water to use in systems for conditioning/heating purposes. The units are not suitable for the production of domestic hot water. Any use differing from this proper use or beyond the operating limits indicated in this manual is forbidden unless previously agreed with the manufacturer.
Safety prescriptions
The units have been designed to comply with the European standards governing safety matters. They thus comply
with the provisions established by Directive 89/392/EEC, 91/368/EEC, 93/44/EEC and the successive modifications
included in 93/68/EEC.

MAIN FEATURES
Description of the components
The complete series for use in systems includes seven sizes ranging from 4.3 to 13.5 kW in cooling mode and
from 4.8 to 14.8 kW in heating mode.
Main components
The technical features of the main components that form the units are:
1. Fans. These are the helical type with scythe-shaped blades to increase the efficiency and reduce the noise level.
2. Compressors. These are the SCROLL type with revolving spiral or SPIRAL, built-in thermal protection and oil
heater for the heat pump units.
3. Bearing structure formed by galvanized sheet metal panels coated with polyurethane powder paints to give good
protection against adverse weather conditions.
4. Evaporator of the braze-welded plate type in stainless steel (AISI 316). It is installed inside a sheel made of heat-
insulating material to prevent the formation of condensation and heat exchanges towards the outside. Standard
supply also includes an anti-freezing resistance and a differential pressure switch on the wet circuit to prevent
freezing in the absence of water.
5. Condensing banks, of the finned pack type in aluminium with a serrated profile to increase the thermal exchan-
ge coefficient and with copper tubes arranged in staggered rows.

MAIN FEATURES
Description of the components
Hydraulic and chilling circuit components:
1. One-way valves (heat pump unit), allow the coolant to pass into the appropriate exchangers, depending on the
operating cycle.
2. Low pressure switch, with fixed setting. This is installed on the intake pipe and blocks the compressor if the ope-
rating pressure drops below the preset values. It automatically resets when the pressure increases. If the pressure switch activates too frequently, the unit blocks and may only be restarted following a reset via the user terminal.
3. High pressure switch, with fixed setting. This is installed on the delivery pipe and blocks the compressor if the
operating pressure rises above the preset value. If it activates, the unit blocks and may only be restarted following a reset via the user terminal.
4. Thermostatic valve, of the external equalizer type. Used in the heat pump mode. it feeds the evaporator cor-
rectly, keeping the set degree of overheating at a constant level.
5. Capillary. Used in the cold mode. Carries out the same function as the thermostatic valve, the only difference
being that the capacity to monitor overheating is less accurate than with the thermostatic valve.
6. Water differential pressure switch. This is part of the standard supply and is installed on the connections bet-
ween the water inlet and outlet of the exchanger. If it activates frequently, the unit blocks and may only be restarted following a reset via the user terminal.
7. 4-way cycle reversal valve (heat pump units), reverses the direction in which the coolant flows as the sum-
mer/winter operating mode is changed.
8. Fluid receiver (heat pump unit), this is a plenum tank that accounts for variations in the coolant charge the machi-
ne must supply as the summer/winter operating mode varies.

INSTALLATION
Handling
Check the weight of the appliance before proceeding with the moving and handling operations. The weight is indicated on the data plate of the appliance and in the “Main Features” section of this manual. Make sure that the
appliance is handled with care and without jolting as rough treatment could damage the functional parts of the
machine.
Comply with the following instructions when lifting and positioning the appliance:
• Carry the packed appliance as near as possible to the installation site using the handles on the pack or the pallet
to which the appliance is fixed.
• Remember that the heavier part of the appliance is the one where the compressor is installed (indicated by a
symbol on the pack).
• All the appliances are supplied in a cardboard box fixed to a pallet in both the longitudinal and crosswise direc-
tions. If a lift truck is used for handling purposes, remember to place suitable material between the truck itself and
the appliance in order to prevent the bank surfaces from being damaged.
Choice of the installation site
Bear the following points in mind before installing the appliance:
• Position the appliance where it is sheltered from the rain and direct sunlight and in a sufficiently ventilated place.
• The appliance must be positioned in a place that is able to bear its weight and where vibrations and noise cannot
be amplified.
• Position the appliance where noise and the air flow are unable to annoy the neighbours.
• The appliance must be installed a certain distance away from walls and furniture, as indicated in Fig.1.
• If the appliance is installed on the floor , avoid places where water is liable to accumulate or drop from gutters, etc.
• In zones where a great deal of snow is likely to fall or where the temperature remains below 0°C for long periods
of time, the appliance must be mounted on a 20-30 cm thick concrete base to prevent snow from building up
around the machine.
• During winter, heat pumps produce condensation that drips on to the bearing surface, forming puddles that are
often annoying and/or unpleasant. To prevent condensation from infiltrating into the machine, it is advisable to
create an accumulation trough under the machine with a channel to convey the condensation towards a drain.
Comply with the minimum distances required as indicated in the drawing on the right.
A=40 cm
B = 15 cm
C = 60 cm
D = 15 cm
If a roofing is installed, it must be higher than the
machine by at least ¾ of the height of the machine
itself.
NOTE: To ensure the ventilation required for correct
operation, the appliance must not be surrounded by
more than three walls.

INSTALLATION
Installation
Use a fork lift truck to lift the appliance during the installation phase (Fig.1).
Keep the appliance in a horizontal position without tilting it. Once it has
been positioned, remove the packing materials (Fig.2). Good protection
against the transmission of vibrations is obtained by placing blocks of resilient material (neoprene, etc.) between the bearing feet of the machine and
the floor.
How to drain off the condensation
Condensation is produced when heat pump units operate in the heating
mode. In this case, it may be necessary to convey the condensation
towards a drain outlet.
Proceed in the following way:
1. Fit the supplied union (1-Fig.3) into the relative hole (2-Fig.3) on the
base of the exterior unit. Fix by inserting the shaped part of the union
into the hole and turning through 90° towards the right or left as required.
2. Connect a sufficiently strong rubber tube (2-Fig.4) (it must not be able
to deform and create throttles) to the union (1-Fig.4).
3. Fix it in place with a pipe clamp (3-Fig.4) and route it into a drain outlet.
4. Make sure that the tube slopes sufficiently to allow the condensation to
flow out naturally.
5. Make sure that the draining action functions correctly by pouring water
into the tray of the exterior unit (only a small amount).
