The condensate may be discharged at a maximum height of

and aligned with the drainage flange.
If it is necessary to discharge the condensate from a level
above 7

in., install an auxiliary water discharge pump and
float valve. A float valve is recommended to stop the compres-
sor if there is a fault at the auxiliary pump.
The condensate pipe must be insulated with condensation
proof material such as polyurethane, propylene or neoprene of

NOTE: If more than one unit is installed in the room, the drain
system can be designed as shown in Fig. 10.
Installing the Grille and Frame Assembly
— Carefully un-
pack the assembly and check for damage sustained in transport.
Attach the assembly to the unit by using the two hooks. See
Fig.11. 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 to position. See Fig. 12.
Ensure that the frame is not distorted by excessive tighten-
ing, that it is aligned with the false ceiling and that there is a
seal between the air inlet and outlet. See Fig. 13. Gasket “A”
prevents return air from mixing with the supply air and gasket
“B” prevents the supply air from leaking into the ceiling void.
Once the unit is mounted in the ceiling, the gap between the
unit frame and the false ceiling must not be more than

wide.
The drain tube extension must be securely fastened to the
condensate drain. Failure to do so could result in conden-
sate water dripping on to the floor, which could cause per-
sonal injury.
