5. Connect the Drain Pipe

A. Install the drainpipe
(1) Adopting the hard PVC pipe(Outer diameter 37-39mm, Inner diameter 32mm),the proper drainpipe can
be purchased from the distributor or market;
(2) Connect the drainpipe to the bottom of the water suction pipe of the main unit and fasten it together with
the water outlet insulating pipe with the clip of the water outlet pipe.
Note: Be gentle to prevent the water suction pipe from cracking.
(3) The water suction pipe and drainpipe (especially the indoor section) should be bound with the water
outlet insulation sleeve and then fasten it with the band to avoid the entrance of air that will cause
condensation.
(4) In order to avoid of the backward flow into the air condition when stopping running, incline the drain pipe
toward the outdoor side (drain side ) with the gradient of more than 1/50. Avoid of any protrusion or water
trap (Refer to Fig a)
(5) Not pull the drainpipe when connecting and set a supporting point every1-1.5m to avoid of bending of
the drainpipe( Refer Fig b);Besides, you can wrap the drainpipe and connection pipe together first and then
fix the fronter with the later ( Refer Fig C)
(6) To connect the drainpipe lengthened, wrap the indoor part with protective pipe to keep it from loosing;
(7) If the outlet of the drainpipe is above the water suction pipe of the main unit, keep the drainpipe vertically
upward as much as possible. The bending part of the pipe adopts the rigid pipe with reliable support and
the rise height of the pipe is less than 20mm to avoid of overflowing for the flow back when stopping.
(8) Keep distance of the end of drainpipe and the ground or the bottom of the waterspout more than 50mm
and not extend into water. When draining directly the condense water to waterspout, bend the drainpipe
upward into the " U" shape to prevent bad smell from entering room.
