<PRECAUTIONS FOR DRAIN RAISING PIPING>
•
Install the drain raising pipes at a height of less than 675 mm.
The drain pump of this unit has a high delivery flow rate. Therefore, the higher the drain raising height is,
the lower the sound of draining will be. For this reason, a minimum drain raising height of 300 mm is rec-
ommended.
•
Install the drain raising pipes at a right angle to the indoor unit and no more than 300 mm from the unit.
NOTE
•
To ensure no excessive pressure is applied to the included drain hose (1), do not bend or twist when install-
ing. (This may cause leakage.)
•
If converging multiple drain pipes, install according to the procedure shown below.
Select converging drain pipes whose gauge is suitable for the operating capacity of the unit.
(2)
After piping work is finished, check if drainage flows smoothly.
WHEN ELECTRIC WIRING WORK IS FINISHED
•
Add approximately 1 L of water slowly from the air outlet and check drainage flow.
Check drainage flow during COOL running, explained under ‘‘12. TEST OPERATION’’.
•
After checking the drainage of water, refer to Fig. 24 and attach the sealing pad (14) to perform the thermal
insulation of the drain socket.
