CONDENSATE PIPE INSTALLATION
1. The condensate pipe should keep a inclination angle of 5 ~
10”, to facilitate the drainage of the condensate water. And
the joints of the condensate pipe should be insulated by the
insulation material to prevent condensing (see Fig. 59).

2. There is a conde nsa t e outl et on both the le ft a nd r i ght si des of
the unit . Once one is conf irm ed for use, the othe r shoul d be
clogged by a rubber plug, bundled by t he bindi ng wir e and
insulated by the insulation material to avoid water leakage.
3. The right outlet is defaulted to be clogged with a plug.
IMPORTANT: No water leakage is allowed on the joint of the
condensate pipe.
DESIGN OF THE DRAIN PIPE
1. The drain pipe should always be kept an inclination angle
(>1/100) to avoid water from gathering.
2. During the conne ction of the drain pipe and devi ce, do not
im pos e e xce ssive force on the pi pe on one si de of t he devi ce.
Additionally the pipe should be se cured cl osely to the device.
3. 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. Never connect the drain
outlet and the drain hose with adhesive.
4. When the drain pipe is used for multiple devices, the public
section of the pipe should be 4 in. (100 mm) lower than the
drain hole of each device and it is better to use the much
thicker pipe for such a purpose.
DRAIN PIPE INSTALLATION
1. The diameter of the drain pipe should be larger than or
equal to that of the refrigerant pipe (PVC pipe, outer
diameter: 1 in. (25 mm), wall thickness
0.06 in. (1.5 mm).
2. The drain pipe should be a short as possible and with at
least a 1/100 degree of slope to avoid forming air pockets.
3. If the proper degree of slope of the drain pipe is not
allowed, a lift pipe should be installed.
4. A dis ta nce of .9 ft . ~ 6.6 ft. (1. 5 m~2 m) should be kept
betwe en the hange rs to avoid the drain hose from maki ng a
turn.

5. Insert the drain hose into the drain hole and tighten it with
clamps.
6. Wrap the clamps with large amount of sponge for thermal
insulation.
7. The drain hose inside the room also should be insulated.
