4.4 Drainage pipe installation
The drainage pipe should be properly insulated to prevent the generation of condensation.
Heat insulation material: the thickness of rubber insulation pipe should be more than 8mm
◇ Drainage pipe must have a downward gradient (1 / 50 1 / 100) to avoid water backflow or
leakage etc.
◇ The unit has a drain pump which will lift up to 700 mm. However after the pump stops the
water left in the pipe will drain back and may overflow the drain tray causing water leakage. For
this reason please install the drain pipe as shown
