Condensate Pipe Installation
1 The condensate pipe should maintain a inclination angle of
5” ~ 10”, to facilitate the drainage of the condensate water.
And the condensate pipe joints should be insulated by the
insulation material to prevent condensing (see Fig. 56).

2 There is a condensate outlet on both the left and right sides of
the unit. Once one is confirmed for use, the other should be
clogged by a rubber plug, bundled by the binding wire 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.
Drain Pipe Design
1 The drain pipe should always be kept an inclination angle
(1/50~1/100) to avoid water from gathering.
2 During the connection of the drain pipe and device, do not
impose excessive force on the pipe on one side of the device.
Additionally the pipe should be secured closely 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 drain pipe diameter 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 as short as possible and with at
least a 1/100 degree of slope to avoid forming air pockets.
3 If the proper slope degree of the drain pipe is not provided,
a lift pipe should be installed.
4 Keep a distance of 3.28 ft ~ 4.92 ft (1m ~ 1.5m) between the
hangers to avoid the drain hose from turning.

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

Lift Pipe Precautions
The lift pipe install height should be less than 33 1/2 in. (850 mm).
We recommend setting an inclination angle 1~2
_
for the lift pipe
toward the drainage direction. If the lift pipe and the unit form a right
angle, the lift pipe height must be less than 31 1/2 in. (800 mm).

NOTE:
1 The drain hose inclination height should be within 3 in.
(75 mm) so that the drain hose outlet does not suffer any
external force.
2 If multiple drain pipes converge, follow the floor console
installation steps in section 42.
The specification of the joint of the drain pipe should be suitable to the running capacity of the unit

Wireless Remote Controller Installation
Mounting Bracket (if installed on the wall)
1 Use the two screws supplied with the controller to attach the
Mounting Bracket to the wall in a location selected by the
customer and within operating range.
2 Install the batteries in the Remote Controller.
3 Place the Remote Controller in the Mounting Bracket.
NOTE: For remote control operation, refer to the unit owner’s
manual. The wireless remote controller should be pointed to
the wired controller to receive the signal.
Wired Remote Controller (shipped with the unit)
For setup instructions, refer to the wired controller installation
manual. Connect the 4−core wire shipped with the unit to CN9 on
the indoor board and CN1 on the wired controller board.
