Refrigerant Piping

• Piping kit used for the conventional refrigerant cannot be used.

• Use copper pipe with 0.8 mm or more thickness for Ø 9,52

mm.

• Use copper pipe with 1.0 mm or more thickness for Ø 15,87 mm.

• Flare nut and flare works are also different from those of the

conventional refrigerant.
Take out the flare nut attached to the main unit of the air
conditioner, and use it.

Notes:

1. Data referred to the outdoor unit only.
2. According to prEN14511.

d.b. - dry bulb;

w.b. - wet bulb

WARNING:
During heat pump operation unit will undergo several defrost cycles to
eliminate ice that might possibly collect on the outdoor unit in very low
ambient temperatures.
In these cycles, fan speed will automatically reduce and cannot be
varied until defrost cycle is completed.

NOTES: Caution at addition of refrigerant

(1)

When the total length of refrigerant pipe exceeds 20m, add 40g/m. The pipe total maximum length is  50 m. (Max. amount of additional refrigerant is
1200g.). Charge the refrigerant accurately. Overcharge may cause a serious trouble of compressor..

to indoor/outdoor units.

Refrigerant addition

.

20 m o shorter: for all units

Do not add refrigerant at installation site

(1)

 from 20 m to 50 m

Add 40 g of refrigerant for every meter of pipe beyond 20 m

Air purge

• For air purge, use a vacuum pump.

• Do not use refrigerant charged in the outdoor unit for air purge.

(The refrigerant for air purge is not contained in the outdoor unit.)

Selection of installation

Electrical cabling

• Be sure to fix the power cables and indoor/outdoor connecting

cables with clamps so that they do not contact with the cabinet,
etc.
