Installation instructions
Piping Joints Thermal Insulation:
Wrap the piping joints with thermal
insulation materials and then wrap
with a vinyl tape.
Piping Thermal Insulation:
a. Place the drain hose under the piping.
b. Insulation material uses polythene foam over 6mm in thickness.
Note: Drain hose is prepared by user.
Drain pipe should point downward for easy drain flow.
Do not arrange the drain pipe twisted, sticking out or wave
around, do not immerse the end of it in water.
If an extension drain hose is connected to the drain pipe, make
