Making the hole for connection pipes in the external wall
• After positioning the units and determining the connection position,
make a 70 mm Ø hole in the wall. The same hole can be used as a
condensate drain pipe conduit.
• The hole should have a 5 - 10 mm slope toward the outside.
Insert the plastic conduit provided.
• Pass the power connection cables through the conduit (see
electrical connections).
Condensate drain pipe
• To ensure correct condensate water flow, the drain pipe should
have a gradient of 2% without obstructions.
Furthermore an odour trap of at least 50 mm depth should be
made to prevent unpleasant odours from reaching the room.
• Condensate may be discharged at a maximum height of 200 mm
above the unit, as long as the ascending tube is vertical and
aligned with the drainage flange.
• If it is necessary to discharge the condensate from a level
above 200 mm, install an auxiliary water discharge pump and
float valve.
A float valve is recommended to stop the compressor if there
is a fault at the auxiliary pump.
• The condensate pipe must be insulated with a condensation-
proof material such as polyurethane, propylene or neoprene of
5 to 10 mm thickness.
• If more than one unit is installed in the room, the drain system can
be made as shown in the drawing.

Installation of grille/frame assembly
Carefully unpack the assembly and check for damage sustained in
transport. Attach the assembly to the unit by using the two hooks.
Tighten the four screws, link the electrical connectors and insert the
wires in the cable clamp.
Use the screws supplied to fix the frame in position.
A AIR B
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.
