Field piping must be connected to the piping
connecting part all the time. If poor thermal
insulation for piping, there will be dew outside
and scald if any touch.

Drainage Pipe Layout
In order to make drainage pipe easy to discharge
condensed water, make the drainage pipe form
declination state, see Figure 10.
If the length of drainage hose which is installed
on the indoor unit is not enough, the drainage
hose in the accessory case may be adopted for
connection, see Figure 11.
When the drainage hose needs to pass through a
room, wrap the commercially available thermal
insulation material.

Electric Installation
Use designated wire to supply power for
controller; do not share the same power supply
with other electric device in order to avoid
overload hazard. Use the fuse or breaker with
suitable working voltage with controller; do not
use wire or fuse exceeding the designated class.
Only use the accessories designated by the
company, and require the manufacturer or
authorized dealer to provide installation and
technical service. If accessories are controlled
improperly, controller failure or electric shock
consequence may be caused.
Control mainboard and transformer shielding
layer must be installed with earthing wire. Do
not connect earth wire with gas fuel pipeline,
water pipe, lightning conductor or telephone
earthing wire. Improper earthing may cause
electric shock accident. Please frequently check
whether the connection of controller earthing
wire and unit earthing terminal and earthing
electrode is firm.
For indoor and outdoor unit connection,
separately wire strong and weak electric wires.

Wiring requirements
All the work related to electric device shall be
completed by professional electrician.
The power supplies of indoor unit and outdoor
unit come from the same distribution box; power
