INSTALLATION MANUAL---Installation of the outdoor unit
The air and humidity left inside the refrigerant circulat-
ion can cause compressor malfunction. After having co-
nnected the indoor and outdoor units, bleed the air and
humidity from the refrigerant circulation using a va-
cuum pump.

(3) Connect the vacuum pump hose to the service port.
(4) Operate the vacuum pump for 10 - 15 minutes until
an absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation , close the
low - pressure knob on the vacuum pump coupling.
Stop the vacuum pump.

1. Wind insulating covering around the joints of the ind-
oor 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 pla-
stic slots.
4. Seal the hole in the wall through which the piping is
passed so that no air or water can fill.
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?
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?
