Have the piping and electrical wiring been installed
correctly?
Risk of malfunction or damage to components.
Has the unit been properly earthed? Risk of electric leakage.
Does the power cable meet requirements? Risk of malfunction or damage to components.
Are there any obstructions at the air inlet or outlet? The cooling (heating) capacity may be insufficient.
Have the dust and other particles produced during
installation been removed?
Risk of malfunction or damage to components.
Are the gas valve and liquid valve of the connecting tube
fully open?
The cooling (heating) capacity may be insufficient.
Have the length of the refrigerating tube and the amount
of the refrigerant charge been registered?
It is not easy to decide the amount of the
refrigerant charge to add.
TESTING AND OPERATION
Functional testing
Connect the power and press the ON/OFF button on the remote control to start operation.
Press the MODE button to select AUTO, COOL, DRY, FAN and HEAT mode and check the air
conditioner operates normally.
If the ambient temperature is below 16°C, the air conditioner will be unable to start cooling.
APPENDICES
Piping configuration
1. Standard connecting tube length:5, 7.5, 8 m.
2. Minimum connecting tube length: 3 m.
3. Maximum connecting tube length and maximum height difference:

Warning! Note the additional charge on the data plate affixed to the outdoor unit.
Additional oil and refrigerant charging
If the length of the connecting pipe is increased by 10 m compared to the standard length, add
5 ml of refrigeration oil for every 5 m of pipe added.
Method for calculating the amount of additional refrigerant charge (liquid pipe): amount of
additional refrigerant charge = additional length of liquid pipe x additional amount of refrigerant
charge per metre.
