Step 2 — Locating and Mounting the Unit

LOCATING THE UNIT — Install the unit as centrally as

possible in the room. The air flow

direction can be controlled

by the remote control (where used) or automatically, according

to the unit operating mode (cooling or heating). Controlling

the airflow automatically will ensure optimum distribution of

the air in the room.

In Cooling mode, the louvers should be positioned so that

the air is directed towards the ceiling. Refer to Fig. 3. In Heat-

ing mode, the louvers should be positioned so that the air is di-

rected toward the floor to prevent layers of hot air forming

close to the ceiling. Refer to Fig. 3. The louvers will be auto-

matically positioned when the louvers are set to Automatic

mode. Alternatively, the louvers can be placed in intermediate

positions (with infrared remote accessory kit only) or allowed

to move continuously (Swing mode).

In order to allow easy and rapid installation and mainte-

nance, ensure that the unit is mounted in a location that is easily

accessible.

Restricting Air Outlets

— A maximum of two air outlets can

be restricted at one time. See Fig. 3. The air supply outlet ob-

struction accessory kit can be used to obstruct air outlets. Con-

tact your local dealer for more information.

MOUNTING THE UNIT — Use a stacker to lift the unit to

the installation location. Refer to Fig. 4. If the mounting loca-

tion is in a plaster board ceiling, the maximum dimensions of

the unit housing cutout must not exceed 2 ft, 2 in. square for

40KMC018 units and 2 ft, 11 in. square for 40KMC024,03036

and 40KMQ01824,03036 units.

NOTE: In rooms with high humidity, brackets should be

insulated using self adhesive insulation.

Mark the position of the hangers, refrigerant lines and

condensate drain pipe, power supply cables and remote control

cable (see Fig. 2 for dimensions). The cardboard template

(supplied with the unit) may be used as a guide. Depending on

the type of ceiling, the hangers can be fixed as shown in Fig. 5.

Once the threaded hangers have been positioned, do not

tighten the nuts. Insert the washers as shown in Fig. 5. First

position the refrigerant lines, as described in the Complete

Refrigerant Piping Connections section. Remove the “T” bar in

the ceiling to facilitate installation. See Fig. 6.

Carefully lift the unit (without the frame) using the four sus-

pension brackets (or the four corners), and insert it into the

false ceiling. If the “T” bar cannot be removed from the ceiling

the unit may need to be tilted. See Fig. 7.

NOTE: Tilting the unit may only be carried out with false ceil-

ings with a minimum height of 11 ft-

inches.

Align and level the unit by adjusting the nuts and locknuts on

the threaded hangers, maintaining a distance of 1 in. to 1

in.

between the sheet metal body and the underside of the false ceil-

ing. See Fig. 8. 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.

Drilling the Hole for Connection Pipes in the External

Wall — After positioning the units and determining the con-

nection position, drill a 2

in. hole in the wall. The same hole

can be used as a condensate drain pipe conduit. The hole

should have a

in. to

in. slope toward the outside. Refer

to Fig. 9. Insert the plastic conduit. Pass the power connection

cables through the conduit The power connection cables will

be connected in the Make Electrical Connections section.

Running the Condensate Drain Piping

— To ensure correct

condensate water flow, the drain pipe should have a gradient of

2% without obstructions. Additionally, a trap of at least 2 in.

depth should be made to prevent unpleasant odors from reach-

ing the room.

Max. 2 louvers closed

Heat pump: louver position for correct airflow.

Cooling: louver position for correct airflow.
