INSTALLATION MANUAL--- operation test

1. Wind insulating covering around the joints of the indoor unit and fix it with insulating tape.
2. Fix the exceeding part of the signal cable to the piping or to the outdoor unit.
3. Fix the piping to the wall (after having coated it with insulating tape) using clamps or insert them into plastic slots.
4. Seal the hole in the wall through which the piping is passed so that no air or water can enter.

Indoor unit test

• Do the ON/OFF and FAN operate normally?
• Does the MODE operate normally?
• Do the set point and TIMER function properly?
• Does each lamp light normally?
• Do the flap for air flow direction operate normally?
  • Is the condensed water drained regularly?

Outdoor unit test

• Is there any abnormal noise or vibration during operation?
  • Could the noise, the air flow or the condensed water drainage disturb the neighbours?
  • Is there any coolant leakage?

Note: the electronic controller allows the compressor to start only three minutes after voltage has reached the system.
