The condensate may be discharged at a maximum height of

77/8 in. above the unit, as long as the ascending tube is verti-

cal and aligned with the drainage flange.

If it is necessary to discharge the condensate from a level

above 77/8 in., install an auxiliary water discharge pump and

float valve. A float valve is recommended to stop the com-

pressor 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 3/16 in. to 3/8 in. thickness. See Fig. 10.

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 unpack the assembly and check for damage sus-

tained 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 ceil-

ing void. Once the unit is mounted in the ceiling, the gap

between the unit frame and the false ceiling must not be

more than 3/16 in. wide.

CAUTION: The drain tube extension must be

securely fastened to the condensate drain. Failure to

do so could result in condensate water dripping on to

the floor, which could cause personal injury.
