• 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 flow switch 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.
Align and level the unit by adjusting the nuts and locknuts on
the threaded hangers, maintaining a distance of 25 -30 mm
between the sheet metal body and the underside of the false
ceiling.
Reposition the "T" bar and align the unit in relation to the bar by
tightening the nuts and locknuts.
After connection of the condensate drain line and the refrigerant
lines, carry out a final check to make sure that the unit is level.
Carefully lift the unit (without the frame) using the four
suspension brackets (or the four corners), inserting it into the
false ceiling.
If the "T" bar cannot be removed the unit may need to be tilted
(this operation may only be carried out with false ceilings with a
minimum height of 300 mm).
First position the connection lines , as described in the chapter
"Water connections".
Remove the "T" bar in order to facilitate installation operations.
