(2}Check if the drainage is proper after completing installation.
After completing wiring installation
• To prevent water from gathering in the electrical
components such as the drain pump, add about
1 000CC water slowly from the air outlet. Check the
drainage condition in accordance with the "12. Field
settings and test run" while performing cooling
operation.

Caution---------------
• All electrical work (including grounding engineering)
must be carried out by the electricians with professional
qualifications.
• If the electricians are absent from the site, check the
drainage using steps 3 to 6 after the system test run is
stopped.
1. Remove the electrical component box cover and
concect the single-phase 50Hz, 220-240V power
circuit to the L and N of the power terminal block.
2. Check if the electrical component box cover has
been fastened completely before turning on the
power supply.
3. To prevent water from gathering in the electrical
components such as the drain pump, add about
1 000CC water slowly from the air outlet.
4. Turn on the power supply to start the drain pump. It is
possible to check the drainage condition through the
transparent part of the drain socket. {The drain pump
will stop automatically after 10 minutes.)

• Be careful that the fan is also rotating now.
• Do not touch the drain pump to prevent electric shocks.
5. After completing drainage inspection (Figures 18 and
19), shut off the power supply and remove the power
wiring.
6. Attach the electrical component box cover as original.

1. It is possible to have the overcurrent circuit breaker
instead of the fuse.
2. If the electric wires are located in the places where they
are easy to be touched by personnel, mount the earth
leakage circuit breaker to prevent electric shocks.
3. Use the earth leakage circuit breaker compatible with
the appliances for grounding over-current protection
and short circuit protection. If the ground protection
special appliance is mounted to the earth leakage circuit
breaker, be sure to mount a line breaker together.
