Unit Hanging

• Confirm the pitch of the hanging rod is 790.0mm x 620.5mm(M5CKWS-AR) and 505.0mm x 538.0mm

(M5CKWS-CR).

• Hold the unit and hang it on the hanging rod with the nut and washer.

• Adjust the unit height to 35.0 mm between the indoor unit bottom surface and the ceiling surface.

• Confirm with a level gauge that the unit is installed horizontally and tighten the nut and bolt to

prevent unit falling and vibration.

• Open the ceiling board along the outer edge of the paper installation template.

Drain Piping Work

• Drain pipe must be downward gradient for smooth

drainage.

• Avoid the drain pipe from up and down slope to prevent

reversal flow.

• During the drain piping connection, be careful not to exert

extra force on the drain connector at indoor unit.

• The outside diameter of the drain connection at the

flexible drain hose is 20 mm.

• Be sure to provide heat insulation (polyethylene foam

with thickness more than 8.0 mm) on the drain piping to

avoid the condensed water dripping inside the room.

Drain Test

• Connect the main drain pipe to the flexible drain hose.

• Feed water from flexible drain hose and check the piping

for leakage.

• When the test is completed, connect the flexible drain

hose to the drain connector on the indoor unit.

Note: This indoor unit use drain pump for condensed water drainage. Installed

the unit horizontally to prevent water leakage or condensation around

the air outlet.
