Checking
Before unit operation pour a quantity of water into the external
auxiliary drain pan. Verify that the water flows into the internal
condensate drain pan and that the pump regularly drains the
liquid.
Otherwise check the pipe slope and look for possible
obstructions. Water connections are fixed to the unit body to
avoid damage when pipes are connected; it is advisable to
tighten the connection with a spanner.

The upper coil connection is supplied with an air purge valve,
the lower connection with a water purge valve, suitable for a
10 mm wrench or screw-driver.
(The coil is only partially drainable; it it is advisable to
blow air into the coil for complete drainage).
It is necessary, when the installation is made, to insulate the
valve and the connection pipes with anti-condensate material
of polyethylene type or expanded neoprene.

that it is aligned with the false ceiling and above all that there is
a seal between the air inlet and outlet.

leaking into the ceiling void.
On completion, the gap between the unit frame and the false
ceiling must not be more than 5 mm.
