2.8 Water connections
The system should be designed and installed
following best practice by a qualified installer. The
choice and sizing of the pipework should take into
account the number and size of the units installed,
and the performance characteristics of each unit.
Undersized pipes can cause malfunction of the units.
The water connection pipes and joints must be
thermally insulated.
Partially insulating the pipes should be avoided and
the insulation should not be over-tightened.
A suitable thread sealant should be used. The use of
Teflon thread sealant is advised when there is anti-
freeze in the hydraulic circuit.
After making the water connections check for leaks
and cover the connections with insulating material.

US 2.9 Condensate discharge
The condensate discharge pipes must be suitably
sized (minimum inside pipe diameter 16 mm / 1/2")
and the pipeline positioned so that it keeps a constant
inclination, never less than 1%. In a vertical installation,
the discharge pipe is connected directly to the
discharge tray, positioned underneath the water
connections. In a horizontal installation the discharge
tube is connected to the one already present in the unit.
For installation of the VS versions in a horizontal
position, horizontal condensation collection tray
accessory kits are available.
• If possible, the condensate pipework should be
directed into a rainwater discharge.
• When discharging directly into the main drains, it is
essential to make a siphon to prevent bad odours coming
up the pipe into the room.The curve of the siphon must be
lower than the condensation collection bowl.
• If the condensate needs to be discharged into
a container, the container must be open to the
atmosphere and the tube must not be immersed in
water so that the normal outflow is not restricted.
• If there is a height difference that could interfere with
the outflow of condensate, a pump must be fitted:
• In a vertical installation mount the pump under the
lateral drainage tray.
• In a horizontal installation the pump position must be
decided according to the specific requirements.
Such pumps are readily available.
On completion of the installation, it is advisable to
check the correct outflow of the condensate by slowly
pouring about 0.5 l (0.5 quarts) of water into the
collection tray in about 5-10 minutes.

Condensate discharge pipe connection – horizontally mounted units
To mount the horizontal condensate tray on the VS
units refer to the instructions supplied with accessory kits.
• Check that the "L" pipe (A) and the flexible rubber
hose are correctly connected to the condensate tray.
• Slide in the side of the unit keeping the pipe in position
up against the front grille.
• Fully close the side checking that the pipe remains
tight in the special groove on the side.
N.B. for a horizontal installation carefully note the
following precautions:
• Make sure that the unit is installed perfectly level
or with a slight inclination towards the condensate
discharge point.
• Carefully insulate the flow and return pipes to the unit
to prevent any drops of condensate falling outside the
drip tray.
• Insulate the condensate discharge pipe (B) along its
complete length.

2.10 Filling and venting the system
When starting up the system, make sure that the return
valve is open. Refer to section 4.3 for correct setting.
If there is no electric power and the valve actuator has
not already been powered up, use the special tool, press
the valve actuator and use the tool to keep it open.
• Open all the shut off valves (manual or automatic).
• Start to slowly fill the system.
• For units installed in a vertical position, open the
highest vent of the heat exchanger; for appliances
installed in a horizontal position, open the highest
positioned vent; for the 4-pipe versions open the
highest vents on both heat exchangers. Vents can be
opened using a screwdriver.
• When water starts coming out of the air vents, close
them and continue filling the system until reaching
the nominal system pressure.
• Check for leaks.
It is advisable to repeat these operations after the
appliance has been running for a few hours and to
periodically check the system pressure.

• the fan does not activate even if there is hot or cold
water in the hydraulic circuit.
• the appliance leaks water during the heating function.
• the appliance leaks water only during the cooling
function.
• the appliance makes an excessive noise.
• condensate forms on the front panel.
Should one of the following faults occur,
contact a qualified installer. DO NOT intervene
personally.
Faults and Troubleshooting
3.2 Fault-finding guide
These operations must be carried out by a qualified installer or by a specialised service centre.
EFFECT CAUSE SOLUTION
A delayed fan start up following set
temperature change or change of function.
The unit valves need time to open and as
a result the hot or cold water takes time to
circulate in the appliance.
Wait for 2 or 3 minutes for the unit valves
to open.
The fan does not function No hot or cold water in the system. Check that the boiler or chiller are
functioning correctly.
The fan does not activate even if there is
hot or cold water in the hydraulic circuit.
The hydraulic valve remains closed
Remove the valve actuator
and check if water circulation is restored.
Check the valve actuator by powering
it from a separate 230V (120V Canada/
US) source. If it activates then check the
electronic control.
The fan motor is blocked or burnt out. Replace motor.
The micro-switch that stops the fan when
the filter grille is opened does not close
correctly.
Check correct fitting of grille and that the
micro-switch contact is activated.
The electrical connections are not correct. Check the electrical connections.
The appliance leaks water during the
heating function.
Leaks in the hydraulic connections of the
system.
Check the leak and fully tighten the
connections.
Leaks in the valve unit. Check the condition of the gaskets.
Condensation forms on the front panel. Front panel insulation damaged or
detached.
Check the correct positioning of the
thermo-acoustic insulation, paying attention
to insulation in the front above the heat
exchanger.
There are drops of water on the air outlet
grille.
In situations of high humidity (>60%)
condensation could form, especially at the
minimum fan speeds
As soon as the humidity starts falling the
phenomenon disappears. In any case the
presence of a few drops of water in the
appliance does not indicate a malfunction.
The appliance leaks water only during the
cooling function.
The condensate tray is blocked. Slowly pour a bottle of water into the low
part of the heat exchanger to check the
drainage; if necessary, clean the tray and/
or increase the inclination of the drainage
pipe.
The condensation discharge does not need
an inclination for correct drainage.
The connection pipes and the valve unit are
not insulated well. Check the insulation of the pipes.
The appliance makes a strange noise.
The fan fouling adjacent parts. Check if the filters are clogged and clean if
necessary
The fan is unbalanced. An unbalanced fan can cause excessive
vibrations in the unit; replace the fan.
Check if the filters are clogged and clean
them if necessary.
Clean the filters.
