INSTALLATION, OPERATION
AND MAINTENANCE MANUAL

CHANGE OF AIR AND RECIRCULATION SYSTEM EXTERNAL AIR INLET WIRING DIAGRAM

WATER CONNECTIONS

- Side knockouts allow connection of a duct for fresh air intake and for conditio­ning an adjacent room.

- Remove the external prepunched anti-condensate insulator and remove the
knockout panels using a punch.

FRESH AIR RENEWAL

Remove the polystyrene partition and insert the baffl e plate.
Use material purchased locally that is suitable for continuous operation with
temperatures of 60°C. The ducts may be in fl exible polyester (with steel spiral
core) or in corrugated aluminium lagged with anti-condensate material (fi bre-
glass 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.

Any additional fan for external air intake (installer’s responsibility) must be con­nected to the terminal block as per the enclosed diagrams. Fan operation is in
parallel to the damper (electrothermal control valve), so that it stops when the
valve closes. Install an air inlet grille on the outside, with an inspectable fi lter
holding frame to prevent the entry of dust and leaves, which could irreparably
obstruct the unit heat exchanger coil.

The following reasons explain why it is necessary to install the 3-way valve:

- Cassettes with a control board that is managed onboard

1) If the water fl 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 ex­changer 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 fl ow via
the valve in cases such as:
a) Where there is a condensate discharge problem (if the valve does not close
the water fl ow, the battery will continue to condense, causing the condensation
basin to overfl ow).
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 conden­sation basin)

3) The unit has been designed to have continuous ventilation and warm or cool
the room by closing or opening the water fl ow: this allows for optimal adjustment
inside the room where it is installed.

- Cassettes with and without a control board that is managed onboard

4) If the unit remains turned off for a long time in cooling mode and the water
fl ow is not closed, droplets of condensation may form at the air outlets, which
will subsequently lead to a dripping unit.

FOR CASSETTES WITH A CONTROL BOARD THAT IS MANAGED ONBOARD

STANDARD WATER CONNECTION TO HEATING/ COOLING SYSTEM

ATTENTION! IT IS COMPULSORY TO INSTALL THE VALVE!

AIR SUPPLY TO AN ADJACENT ROOM

Remove the polystyrene, taking care not to damage the behind heat exchanger
coil to the rear.
Do not use the two knockout side openings for air ducting to an adjacent room
simultaneously.

ATTENTION!

1) Ducting air to an adjacent room requires the closure of at least the
corresponding duct end.

2) When valves are installed, the air ducts to the “D” adiacent room are
unusable (pict. 11).
