direction of the pipes to be drawn out. Especially in case there is a ceiling, position
the refrigerant pipes, drain pipes, indoor & outdoor lines to the connection places
before hanging up the machine.

1. Install indoor unit drain pipe
The outlet has PTI screw thread, Please use sealing materials and pipe sheath
( tting) when connecting PVC pipes.
Cautions
• The drain pipe of indoor unit must be heat insulated, or it will condense dew,
as well as the connections of the indoor unit.
• Hard PVC binder must be used for pipe connection, and make sure there is no
leakage.
• With the connection part to the indoor unit, please be noted not to impose
pressure on the side of indoor unit pipes.
• When the declivity of the drain pipe downwards is over 1/100, there should not
be any winding.
• The total length of the drain pipe when pulled out traversely shall not exceed
20m, when the pipe is over long, a prop stand must be installed to prevent
winding.
• Refer to the gures on the right for the installation of the pipes.

2. Drainage test
• Check whether the drainpipe is unhindered
• New built house should have this test done before paving the ceiling.
3. Drain Elbow Installation
Fit the seal into the drain elbow, then insert the drain elbow into the base pan hole
of outdoor unit, rotate 90 ° to securely assemble them. Connect the drain elbow
with an extension drain hose (Locally purchased), in case of the condensate
draining o the outdoor unit during the heating mode. (Refer to Chart 17)

Attaching wiring
1. The air conditioner should use separate power supply with rated voltage
2. The external power supply to the air conditioner should have ground wiring,
which is linked to the ground wiring of the indoor and outdoor unit.

(Slide insertion)
3. The wiring work should be done by quali ed persons according to circuit

drawing.
4. A leakage protector should be installed according to the National Standard
concerning electrical appliance.
5. Be sure to locate the power wiring and the signal wring well to avoid cross-
disturbance and their contact with connecting pipe or stop valve body
6. The wiring attached to this air conditioner is 10m long. Be sure to prolong it
with wiring of the same type and proper length if necessary. Generally, do not
