Installation

Installation of grille/frame assembly

Carefully unpack the assembly and check for damage sustained in
transit.  Attach the assembly to the unit by using the two hooks.

Use the screws supplied to fix the frame in position.

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.

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.

 

Ensure that the frame is not distorted by excessive tightening,
that it is aligned with the false ceiling and above all that there is
a seal between the air inlet and outlet.
In the drawing gasket "A" prevents return air from mixing with
the supply air and gasket "B" prevents the supply air from
leaking into the ceiling void.
On completion, the gap between the unit frame and the false
ceiling must not be more than 5 mm.
