CHANGE OF AIR AND RECIRCULATION SYSTEM
- Side knockouts allow connection of a duct for fresh air intake and for conditio-
ning an adjacent room.
- Remove the external prepunched anti-condensate insulator and remove the
knockout panels using a punch.
FRESH AIR RENEWAL
Remove the knockout holes and the insulation. The ducts may be in exible polyester (with steel spiral core) or in corrugated aluminium lagged with anti-condensate material (breglass 12±25 mm thick). Upon completion of installation,
surfaces that have not been insulated may be covered with anti-condensate
insulating material (e.g.: 6 mm thick expanded neoprene).
Failure to comply with these instructions could cause dripping due to
the condensate; the manufacturer cannot be held responsible for any
damage.

WATER CONNECTIONS
The following reasons explain why it is necessary to install the 3-way valve:
- Cassettes with a control board onboard
1) If the water ow is not closed via the valve when the room temperature is
reached, the air sensor installed in intake mode is conditioned by the heat ex-
changer that cools it or heats it via natural convection. The result is that the unit
will not adjust the temperature correctly or it will not go on.
2) The unit has a protection system that intervenes by closing the water ow via
the valve in cases such as:
a) Where there is a condensate discharge problem (if the valve does not close
the water ow, the battery will continue to condense, causing the condensation
basin to overow).
b) The user inserts the incorrect function on the remote control: hot as opposed to cold.
c) The water temperature rises to 80 °C (which damages the main conden-
sation basin)
3) The unit has been designed to have continuous ventilation and warm or cool
the room by closing or opening the water ow: this allows for optimal adjustment
inside the room where it is installed.
- Cassettes with and without a control board onboard
4) If the unit remains turned off for a long time in cooling mode and the water
ow is not closed, droplets of condensation may form at the air outlets, which
will subsequently lead to a dripping unit.
ATTENTION!
- Always use suitably sized wrenches to x or slacken the water pipes.
- It is essential to insulate pipes, valves and connections correctly in order
toavoid the formation of condensation, which could drip into suspended
ceilings causing considerable problems.
The water connections are xed to the unit body to avoid damage when pipes are connected. It is advisable to tighten the connection with a wrench. The
upper coil connection is tted with an air valve and the lower connection with
a drain valve, suitable for a 10 mm wrench or screwdriver. (The coil is only
partially drainable; it is advisable to blow air into the coil for complete drainage)
STANDARD WATER CONNECTION TO HEATING/ COOLING SYSTEM
ATTENTION! IT IS COMPULSORY TO INSTALL THE VALVE!
For air supply to an adjacent room and fresh air intake remove sheet knockout
holes anr the insulation.
ATTENTION!
Ducting air to an adjacent room requires the closure of at least the corresponding duct end.
