6. Refrigerant pipe and drain pipe specifications
To avoid dew drops, provide ����� antisweating and insulating work to the
refrigerant and drain pipes.
When using commercially available refrigerant pipes, be sure to wind commer-
cially available insulating material (with a heat-resisting temperature of more
than 100°C [212°F] and thickness given below) onto both liquid and gas pipes.
Be also sure to wind commercially available insulating material (with a form
polyethylene's ���� gravity of 0.03 and thickness given below) onto all pipes
which pass through rooms.
1 Select the thickness of insulating material by pipe size.
Pipe size
6.4 mm to 25.4 mm [1/4 in to 1 in]
28.6 mm to 38.1 mm [1-1/8 in to 1-1/2 in]
2 If the unit is used on the highest story of a building and under conditions of
high temperature and humidity, it is necessary to use pipe size and insulating
material's thickness more than those given in the table above.

u To ensure that drain is discharged, be sure to hang the unit at level us-
ing a level.
Caution:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
