• 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 545 mm.
• 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.

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 sup-
ply 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.
