Test operation

1. Preparation of test operation

● The client approves the air conditioner.

● Specify the important notes for air conditioner to the client.

2. Method of test operation

● Put through the power, press ON/OFF button on the remote controller to start
operation.

● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check
whether the operation is normal or not.

● If the ambient temperature is lower than 16℃, the air conditioner can’t
start cooling.

Configuration of connection pipe

1. Standard length of connection pipe

● 5m, 7.5m, 8m.

2.Min. length of connection pipe is 3m.

3.Max. length of connection pipe and max. high difference.

4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe

● After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml of refrigerant oil for each additional 5m

of connection pipe.

● The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):

Additional refrigerant charging amount = prolonged length of liquid pipe ×
additional refrigerant charging amount per meter

● Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See the

following sheet.
