•
Drain socket
•
Wrap the attached sealing pad (10) over the clamp and drain hose to insulate.
<PRECAUTIONS FOR DRAIN RAISING PIPING>
•
Install the drain raising pipes at a height of less than 545mm.
•
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 installing. (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.
•
Add approximately 1000 cc of water slowly from the air outlet and check drainage flow.
WHEN ELECTRIC WIRING WORK IS FINISHED
•
Check drainage flow during cooling operation
.
WHEN ELECTRIC WIRING WORK IS NOT FINISHED
•
Remove the control box lid. Connect the single phase power supply (SINGLE PHASE 50Hz
220-240V) to connections No.1 and No.2 on the power supply terminal block. Do not
connect to No.3 of the power supply terminal block. (The drain pump will not operate.) When
carrying out wiring work around the control box, make sure none of the connectors come
undone. Be sure to attach the control box lid before turning on the power.
•
After confirming drainage (Fig.23, Fig.24), turn off the power and remove the power supply.
•
Attach the control box lid as before.
