rain, be careful that heat radiation from the condenser is not
obstructed.

• There should not be any animal or plant which could be

affected by hot air discharged.

• Keep the spaces indicated by arrows from wall, ceiling,

fence or other obstacles.

• Do not place any obstacles which may cause a short circuit

of the discharged air.

• If piping length is over 10m, additional refrigerant should be

added as shown in the table.

If the unit is installed at a 12m distance, the quantity of
additional refrigerant should be 40g ...... (12 - 10) m x 20g/m =
