4.3.2 Drainage Pipe Installation
(1) Drainage pipe should have the same diameter or larger diameter than the connecting pipes
(PVC pipe, outside diameter 25mm, thickness≥1.5mm)
.
(2) Keep drainage pipe short and sloping downwards at a gradient of at least 1% for preventing
forming air bubbles.
(3) If the gradient of drainage pipe could not meet the installation requirements, raising pipe should
be applied.
(4) Insert the drainage hose into drain socket, tighten the metal clamp securely.
(5) Warp the sealing pad over drain hose and metal clamp for heat insulation.
(6) Make sure to perform insulation work for all drainage piping in order to prevent any possible
water drop due to dew condensation.
(7) Apply the suitable diameter for converging drainage pipe according to the operating capacity of
the unit.

(8) The installation height of raising pipe for drainage should be lower than B. The gradient from
raising pipe towards drainage direction should be at least 1%~2%. If the raising pipe is vertical
with the unit, the raising height should be less than C.
