INSTALLATION I
CHOICE OF INSTALLATION SITE
Before installing the unit, agree with the customer the site
where it will be installed, taking the following points into con-
sideration:
- check that the fixing points are adequate to support the
weight of the unit;
- pay scrupulous respect to safety distances between the
unit and other equipment or structures to ensure that air
entering the unit and discharged by the fans is free to cir-
culate.
- Follow the instructions shown in the chapter on DIMEN-
SIONAL DRAWINGS to allow room for maintenance oper-
ations. If installing multiple units the clearances must be
doubled.
POSITIONING
Before handling the unit, check the capacity of the lift equip-
ment used, respecting the instructions on the packaging.
To move the unit horizontally, make appropriate use of a lift
truck or similar, bearing in mind the weight distribution of the
unit.
To lift the unit, insert tubes long enough to allow positioning
of the lifting slings and safety pins in the special holes in the
base of the unit.
To avoid the slings damaging the unit, place protection
between the slings and the unit.
The unit should be installed on special vibration dampers.
See the chapter on DIMENSIONAL DRAWINGS for the sup-
port positions identified by W1, W2 etc. and the correspond-
ing weights for the correct sizing of the vibration dampers.
Fix the unit, making sure it is level and that there is easy
access to water and electrical components.
If the site is exposed to strong winds, fix the unit adequately
using tie rods if necessary.
In heating mode the unit produces a significant quantity of
condensate, which must be suitably drained.
Condensate drainage must not cause problems to objects or
people.
If the outside air temperature is less than 0°C, the conden-
sate may freeze; in these case fit a frost protection heater
on the drain line.
For correct operation of the unit, avoid the following: obsta-
cles to air flow, leaves that may block the heat exchange
coil, strong winds that stop or reinforce air flow, sources of
heat too close to the unit, recirculation or stratification of air.

WATER CONNECTIONS I A
The choice and installation of components is the responsibil-
ity of the installer who should follow good working practice
and current legislation.
Before connecting the pipes, make sure they do not contain
stones, sand, rust, dross or other foreign bodies which might
damage the system.
Construction of a bypass is recommended to enable the
pipes to be washed through without having to disconnect
the unit (see drain valves).
The connection piping should be supported in such a way
as to avoid it weighing on the unit.
The following components should be installed in the water
circuit:
1. Two pressure gauges with a suitable scale (intake and
outlet);
2. Two vibration damper joints (intake and outlet);
3. Two gate valves (normal in intake and calibrating in out-
let);
4. A flow switch (inlet). The flow switch must be cali-
brated by the installer to a value equal to 70% of rat-
ed flow.
5. Two thermometers (intake and outlet);
6. An intake filter must be installed as close as possi-
ble to the unit and positioned to allow easy access
for routine maintenance.
7. All the pipes must be insulated with suitable material to
prevent the formation of condensate and heat loss.
The insulating material must be a vapour barrier.
Make sure that the control and shut off devices protrude
from the insulation.
8. At the lowest points in the system, install drain valves for
easy emptying.
9. At the highest points in the system, install automatic or
manual air vent valves.
10. The unit is fitted as standard with an expansion vessel;
make sure this is correctly sized for the water content of
the system and the expected operating temperature, oth-
erwise install an additional expansion vessel.
La mancata installazione dei flussostati non assicura una
Failure to install the flow switches will mean the heat
exchangers are not protected in the event of no flow of liq-
uid.
Climaveneta cannot be held liable for any damage to the
unit and/or the system following the failure to install these
devices or the filter.
The correct operation of the components that help ensure
the safety of the appliance and the system should be
checked regularly. Specifically, this involves cleaning the fil-
ters and checking the operation of the flow switches
installed.
Make sure that the frost protection heaters on the heat
exchanger are powered when the unit is off (unit in standby
“StbY”)
Water flow to the chiller unit must conform to the values
shown in the section on “General Technical Data”.
The flow of water must be maintained constant during oper-
ation.
The water content of the unit must be such as to avoid dis-
turbing operation of the refrigerant circuits.
The unit must be prevented from freezing at outside air tem-
peratures around 0°C. It is recommended to use suitable
percentages of antifreeze (see “Water circuit data”), protect
the piping with heating sheaths, and empty the system,
making sure there no water remains at the lowest points in
the circuit.
It is recommended to use non-toxic food grade antifreeze,
compliant with the standards in force in the countries where
the unit is used, if domestic hot water production is also fea-
tured.

The heat pumps must be fitted with a filling/top-up sys-
tem connected to the return line and a drain valve in the
lowest part of the system.
Systems containing antifreeze or covered by specific
legislation must be fitted with low-loss headers.
The manufacturer is not liable for obstruction, breakage
or noise resulting from the failure to install filters or
vibration dampers.
Particular types of water used for filling or topping up
must be treated with appropriate treatment systems.
For reference values, see the table.
CONDENSATE DRAIN
The unit is fitted with condensate pan; this must be connect-
ed to a drain system to take away the water that forms, see
the drawing.
If the outside air temperature is less than 0°C, the conden-
sate may gradually freeze.
The unit must be supported on a suitable structure or brack-
ets to keep it off the ground, with a frost protection heater fit-
ted on the drain line.

FILLING THE SYSTEM
- Before starting to fill, place the unit mains
switch QF1 in the OFF position.
- Before filling, check that the system drain
valve is closed.
- Open all system and terminal air vents.
- Open system shut off valves.
- Start filling by slowly opening the system water fill valve out-
side the unit.
- When water begins to leak out of the terminal air vent valves,
close them and continue filling until the pressure gauge indi-
cates a pressure of 1.5 bars.
The system must be filled to a pressure of between 1
and 2 bars.
It is recommended that this operation be repeated after
the unit has been operating for a number of hours. The
pressure should be checked regularly and if it drops
below 1 bar, the water content should be topped-up.
Check the tightness of the joints.
EMPTYING THE SYSTEM
- Before starting to empty, place switch QF1
in the OFF position
- Make sure the system fill/top-up water
valve is closed.
- Open the drain cock outside the unit and
all the installation and terminal air vent
valves..
If the fluid in the circuit contains antifreeze, it should
not be allowed to drain freely, as it is pollutant.
It should be collected for possible reuse.
When draining after heat pump operation, take care as
the water may be hot (up to 50°).

All the terminals referred to in the following explanations are to be found on the terminal board located inside the elec-
trical panel and called “installer terminal block” or “electronic controller A1 terminals” (see wiring diagram).
FIXED SET POINT OPERATION CONTACT (SA6)
Contact SA6 allows operation of the heat pump with a fixed
outlet set point defined by parameter 5952 (default = 50°C).
Closing the contact disables the outside temperature probe
and the room unit, the outlet temperature depends exclu-
sively on the set point set for parameter 5952.
ROOM UNIT (A3)
Installation instructions
The room unit must be located in a reference room to con-
trol the room temperature, keeping in the following factors
consideration:
INSTALLER CONNECTIONS I A
REMOTE ALARM (RD1)
For remote display of unit shut-down due to an operating
fault, an audible or visual alarm warning device can be con-
nected between terminals 6 and 7.
Connect the phase to terminal 7 and the alarm signal device
between terminal 6 and the neutral N.
ELECTRIC HEATER CONTACT (SA1)
To use an electric heater as an auxiliary heating element for
the production of domestic hot water.
Follow the instructions shown on the instruction sheet
enclosed with the electric heater kit if supplied by Cli-
maveneta, otherwise see the wiring diagram in this manual.
For further details see the chapter “Control”.
BOILER CONTACT (SA2)
To use a boiler as an auxiliary heating element or to replace
the heat pump, connect the phase to terminal 11 and the
control device, auxiliary relay, between terminal 10 and the
neutral N.
For further details see the chapter “Control”.
DEACTIVATION CONTACT FOR EXCESS POWER CON-
SUMPTION (SA3)
The heat pump accepts a external deactivation signal from
contact SA3, if using a system for managing power con-
sumption that disconnects active devices based on set prior-
ity, so as to avoid the overload switch on the power meter
from being triggered.
Connect the external contact to terminals 16 and 17.
Contact SA3 closed, heat pump operation disabled.
Contact SA3 open, heat pump operation enabled.
REDUCED ELECTRICITY RATE CONTACT (SA4)
The heat pump accepts an external signal from contact SA4
to activate the forced refilling of the reserve storage tanks
based on different electricity rates during the day.
During reduced rate periods, the heat pump can be forced
on so as to heat the domestic hot water or system storage
tank, where fitted.
Connect the external contact to terminals 18 and 19.
Contact SA4 closed, heat pump operation enabled (forced
operation during the reduced rate period).
Contact SA3 open, heat pump operation disabled.
CONTACT (SA5)
Not used
COMPRESSOR ON SIGNAL (GN1)
For remote display of the compressor operating status, an
audible or visual alarm warning device can be connected
between terminals 12 and 13.
Connect the phase to terminal 13 and the signal device
between terminal 12 and the neutral.
CONNECTING A FLOW SWITCH (F3)
If a flow switch is used, connect it to terminals 14 and 15 on
the installer terminal board, after having removed the
jumper.
DOMESTIC HOT WATER 3-WAY VALVE (YV3)
To configure a 3-way for the production of domestic hot
water (supplied by Climaveneta), make the following con-
nections as shown on the instruction sheet enclosed with
the accessory.
The 3-way valve for the domestic hot water production, if not
supplied by Climaveneta, should have the following charac-
teristics:
- Voltage 230V AC, 50/60 Hz
- Opening and closing time 10s.
- P delta 500 kPa
- Fluid temperature 0°C to 90°C
Use three-way valves with a pressure drop below 20 kPa.
For further details, see the chapter on “Operating character-
istics”.

• The room unit must be located around 1.5 metres from the floor, in a part of the room where the sensor can measure the room
temperature as precisely as possible; it must be sheltered from streams of cold air, sunlight or other sources of heat.
• If mounted on the wall, at the top of the room unit there must be enough space for assembly and removal when necessary.
The room unit, once removed from its base, is no longer powered and consequently is not working.
Installation procedure:
1. Press the plastic hooks, right and left, on the
support.
2. Remove the top part of the support
3. Fasten the support to the wall
4. Make the electrical connections, see the
wiring diagram, and attach the top part of the
support
5. Attach the room unit to the support.
