INSTALLATION MANUAL---Installation of the outdoor unit
BLEEDING
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.
(1) Unscrew and remove the caps from the 2 - way and
3-way valves.
(2) Unscrew and remove the cap from the service port.
(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.
(6) Open the 2 - way valve by 1/4 turn and then close it
after10 seconds. Check all the joints for leaks using
liquid soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves.
Disconnect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.
INSTALLATION MANUAL--- operation test
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.
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.
