THE INDOOR UNIT INSTALLATION
Test and check
* After all workings are finished, check the
working and operation.
- Air distribution : Is the air circulation good?
- Drain : Is the drainage smoothly and no
sweating?
- Gas leakage : Is the piping connection cor-
rectly?
- Wiring : Is the wiring connection correctly?
- Lock-bolt : Is the lock-bolt of compressor
loosened?

Checking the Drainage

Checking the Drainage
* Check the drainage.
- Spray one or two glasses of water upon the
evaporator.
- Ensure that water flows drain hose of indoor
unit without any leakage.
