NOTE:
The appliance shall be installed in accordance with national wiring regulations.
The appliance must not be installed in the laundry.
The appliance must be installed 2.5m above the floor.
The appliance must be positioned so that the plug is accessible.
For some models whose cooling capacity are above 4600W (17000BTU/h),
an all-pole disconnection device which has at least 3mm separation distance in
all pole and a residual current device(RCD)with the rating of above 10mA shall
be incorporated in the fixed wiring according to the national rule.

NOTE:
The drain hose must be arranged beneath the connecting pipe. Drain hose
The drain hose must not be hunched or twisted.
While wrapping up the drain hose, do not pull it.
The drain hose through the room must be wrapped up by the
thermal insulation materials.

ROUTE OF PIPE
If pipe comes out of the right side of the indoor unit, cut part
1 of the unit;
If pipe comes out of the lower-right side of the indoor unit, cut
part 2 of the unit;
If pipe comes out of the left side of the indoor unit, cut part 3

READJUSTMENT OF DRAIN HOSE
If pipe comes out of the left side of the indoor unit, the drain hose
must be refitted, otherwise water leakage may occur.
Readjustment methods: Interchange the position of drain hose
and drain rubber plug.
Clearance is not allowed after refit, it would lead to water leakage.

5 Pipe Connection
The number of bent position of the pipe in the indoor unit should not exceed 10.
The number of bent position of the pipe in the indoor unit and the outdoor unit should not exceed 15.
The radius of bent position should be more than 10cm.
Please break the evaporator craft tube with pincers before connecting. After exhausting the inside air,
use the wrench to twist down the nut of connecting tube of the evaporator.(Fig. 1)
Put some seal oil to cover the joint and the flare.
Align the centre of joint in line with that of flare and tighten the nut of connecting pipe with wrench.(Fig. 2)
Attention:
Do not exhaust the inside air just by loosing the nut since there is the air of certain pressure
inside the tube of indoor unit.
Please do not make extra effort for fear of damaging the expansion orifice.

Notice:
If not include the connect diagram you need, please see the wiring diagram.
If you find the color of connecting cable not comply with the top diagram, please take
real objects as major reference. But the terminal of the same sign must be joint with
the connecting cable of the same color.
The plug housing 1 is connected to the matched receptacle housing of the indoor unit.
The plug housing 2 is connected to the matched receptacle housing of the outdoor unit.
If the signal wire has to be bought separately, choose electric wire above 0.75mm.
If not include the connect diagram you need, please see the wiring diagram.
If the interconnection cord for power supply has to be replaced, please see the
following table for reference.

WARNING:
Please take the electric circuit diagram attached to the indoor/outdoor units as major
reference while installing.
The power wire and signal wire between the indoor/outdoor units must be connected
one by one as per corresponding number on the wiring terminal board.
The connecting cables must be clipped together.
Special cable must be used to connect indoor unit and outdoor unit. It should be ensured
that the terminals are not influenced by external force. Poor connection may cause fire.
The electric box cover must be mounted and secured in position, otherwise fire or electrical
shock may occur because of dust or moisture.
The temperature of refrigerant circuit will be high, please keep the interconnection cable away
from the connecting tube.
All the models shall be connected with the mains which has system impedance limitations.
While installing the unit, please see the following table for impedance information or consult
with the supply authority.(The following information and specifications are subject to change
without prior notice due to continuing research.)

2 Installation of the drain joint (only for heat pump type)
Insert the outdoor double-channel drain joint in one of the
bottom holes of the suitable size then connect drain hose
and joint together.

Align the centre of joint in line with that of flare and tighten the nut of connecting pipe
with wrench. ( Adjust the torque by the same method of connecting pipe for indoor unit.)
4 Air exhausting
Screw down the cap of both gas shut-off valve and
liquid shut-off valve as well as the nut of service port.
Use Allen wrench to turn the valve cork of liquid side
at 90 counter-clockwise, and close it after 10 seconds.
Use soapy water to check the gas leakage especially
at all joint. If there is no gas leakage, please turn the
valve cork of liquid side at 90 counter-clockwise again.

Notice:
Do not vent refrigerant into atmosphere: refrigerant is a fluorinated greenhouse gas, covered by
Kyoto protocol, with a Global Warming Potential (GWP) =1900(R410A)/1600(R407C)/1700(R22).
5 Process of flared tube
Use the pipe cutter to cut off the broken part of flare.
Remove burrs at the cut of the flare.
Insert a nut into the connecting pipe and do flaring
with specified flaring tools, reamers for example.

7 Operation test
Before test operation, wiring safety inspection must be carried out carefully again.
1. Emergency switch operation: Every press of emergency switch, the
air conditioner runs as in the following order:
Cool only type: Cool
Shut off
Heat pump type: Cool
Heat
Shut off
2. Remote controller operation: If the indoor unit sounds like Di, Di when pressing I/O button,
that indicates the air conditioner is under the operation of remote controller. After that, press
every button to test their functions.
3.Check switch operation: Open the front grille and press the check button. Switch on the power
source and then the operation test is activated. If the indicator lamps light up at first and then
go out in succession or the LED window of the indoor unit illuminates at first and then goes out,
the system is under normal operation. If one of the indicator lamps is flashing at all times, or
failure codes are displayed on the LED window of the indoor unit, the system has something
wrong and please check malfunction immediately.
