6. Refrigerant pipe and drain pipe specifications
To avoid dew drops, provide sufficient antisweating and insulating work to the
refrigerant and drain pipes.
When using commercially available refrigerant pipes, be sure to wind commercially
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.
Insulate all indoor pipes with form polyethylene insulation with a minimum density of
0.03 and a thickness as specified in the table below.

5.2. Confirming the unit's position and fixing
► Ensure that the hanging bolt nuts are tightened to fix the hanging bolts.
► To ensure that drain is discharged, be sure to hang the unit at level using
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
1 Select the thickness of insulating material by pipe size.
