6. Drain piping
6.1 Installation of drain pipe for Indoor Unit
Caution:
1) Condensate drain piping must be properly insulated by close cells’ insulating material of suitable thickness,
near connection point on Indoor Unit and on the first portion (at least 1m). This precaution is for avoiding
condensation forming on drain piping‘s outside.
2) For drain piping, please use a PVC of commercial type (VP25).
3) When installing piping on drain connection on Indoor Unit, take care not to force excessively in order not to
damage the connection itself.
4) Keep a slope of 1/50~1/100 along whole piping path. Pipe must not be wavy or higher than specified.
5) It is advised to reduce drain piping lenght up to max. 20m, and to arrange, if needed, special supporting
structures which prevent piping from bending under its own weight.
6) For proper installation, please refer to the Figures below.
