b. There is a condensate outlet on both left and right sides of the unit. Once one is
confirmed to be used, the other should be clogged by a rubber plug, bundled by the
binding wire and insulated by the insulation material to avoid water leakage.
c. The right outlet is defaulted to be clogged with a plug.
CUATION!
No water leakage is allowed on the joint of the condensate pipe.

9 Design of the Drain Pipe

a. The drain pipe should always keep an inclination angle(1/50~1/100) to avoid
the water gathering in some certain place.
b. During the connection of the drain pipe and device, do not impose too much
force on the pipe on one side of the device and the pipe should be fixed as close as to
the device.
c. The drain pipe can be the ordinary hard PVC pipe which can be purchased
locally. During the connection, inset the end of the PVC pipe to the drain outlet, then
tighten it with the drain hose and binding wire but never connect the drain outlet and the
drain hose by adhesive.
d. When the drain pipe is used for multiple devices, the public section of the pipe
should be 100mm lower than the drain hole of each device and it is better to use the
much thicker pipe for such a purpose.

10 Installation of the Drain Pipe

a. The diameter of the drain pipe should be larger or equal to that of the refrigerant
pipe (PVC pipe, outer dimater:25mm, wall thickness≥1.5mm.
b. The drain pipe should be as short as possible and with at least a 1/100 degree of
slope to avoid forming air pockets.
c. If the proper degree of slope of the drain pipe is not allowed, a lift pipe should be
installed.
d. A distance 1-1.5m should be kept between the hangers to avoid the drain hose
making a turn.
