Outdoor Unit
Fix the unit to concrete or block with bolts( 10mm) and nuts firmly and horizontally.
When fitting the unit to wall surface, roof or rooftop, fix a supporter surely with nails
or wires in consideration of earthquake and strong wind.
If vibration may affect the house, fix the unit by attaching a vibration-proof mat.
Place, robust not causing vibration, where the body can be supported
sufficiently.
Place, not affected by heat or steam generated in the vicinity, where
inlet and outlet of the unit are not disturbed.
Place, possible to drain easily, where piping can be connected with the
outdoor unit.
Place, where cold air can be spread in a room entirely.
Place, nearby a power receptacle, with enough space around. (Refer
to drawings).
Place where the distance of more than lm from televisions, radios,
wireless apparatuses and fluorescent lamps can be left.
In the case of fixing the remote controller on a wall, place where the
indoor unit can receive signals when the fluorescent lamps in the room
are lightened.

sufficiently ventilated.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
Place, where a distance marked is available as illustrated
in the above figure.
Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it.
To this unit, both liquid and gas pipes shall be insulated
as they become Iow temperature in operation.
Use optional parts for piping set or pipes covered with
equivalent insulation material.

Draw pipes and the drain hose, then fasten them with the adhesive tape
In case of left side piping, cut away, with a nipper, the lid for left piping.
In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear
piping which is marked on heat insulation materials.
1. Insert the drain hose into the dent of heat insulation materials of indoor unit.
2. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then
connect them.
3. Coat the flaring seal face with refrigerant oil and connect pipes.
Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape
Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.
Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according
to the position of wall hole. When bending, be careful not to crash pipes.
Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation
of connecting part specially.
Hang surely the unit body onto the upper notches of the
mounting plate. Move the body from side to side to verify
its secure fixing.
In order to fix the body onto the mounting plate,hold up
the body aslant from the underside and then put it down
perpendicularly.
Remove terminal cover at right bottom corner of indoor unit, then
take off wiring cover by removing its screws.

When connecting the cable after installing the indoor unit
When connecting the cable before installing the indoor unit
1. Insert from outside the room cable into left side of the wall hole, in which
the pipe has already existed.
2. Pull out the cable on the front side, and connect the cable making a loop.
Insert the cable from the back side of the unit, then pull it out on the front side.
Loosen the screws and insert the cable ends fully into terminal block, then tighten the screws.
Pull the cable slightly to make sure the cables have been properly inserted and tightened.
After the cable connection, never fail to fasten the connected cable with the wiring cover.
Note:When connecting the cable, confirm the terminal number of indoor and outdoor units carefully. If wiring
is not correct, proper operation can not be carried out and will cause defect.
1. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar
qualified person.The type of connecting wire is H05RN-F or H07RN-F.
2. If the fuse on PC board is broken please change it with the type ofT.3.15A/250V.
3.The wiring method should be in line with the local wiring standard.
4.After installation, the power plug should be easily reached.
5. A breaker should be incorporated into fixed wiring. The breaker should be all-pole switch and the
distance between its two contacts should be not less than 3mm.

2.Connection of pipes
Install according to
To bend a pipe, give the roundness as large as possible not to crush the pipe ,and the bending radius
should be 30 to 40 mm or longer.
Connecting the pipe of gas side first makes working easier.
The connection pipe is specialized for R410A.
The max vertical distance between the indoor unit and the outdoor unit is 5 m.
Be careful that matters, such as wastes of sands, etc. shall not enter the pipe.
The standard pipe length is 5m. If it is over 5m, the function of the unit will be affected. If the pipe has
to be lengthened, the refrigerant should be charged, according to 20 g/m. But the charge of refrigerant
must be conducted by professional air conditioner engineer. Before adding additional refrigerant,
perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then charge
additional refrigerant.
Half union
Use the same method on indoor unit. Loosen
the screws on terminal block and insert the
plugs fully into terminal block, then tighten the
screws.
Insert the cable according to terminal number
in the same manner as the indoor unit.
If wiring is not correct, proper operation can
not be carried out and controller may be
damaged.
Fix the cable with a clamp.
Drain hose
If the drain-elbow is used, please attach it as
figure.
Flare nut Forced fastening without careful
centering may damage the
threads and cause a leakage of gas.

5.Purging Method:To use vacuum pump
Detach the service port's cap of 3-way valve, the
valve rod's cap for 2-way valve and 3-way's, connect
the service port into the projection of charge hose
(Iow) for gaugemanifold.Then connect the projection
of charge hose (center) for gaugemanifold into
vacuum pump.

Open the handle at Iow in gaugemanifold, operate
vacuum pump. If the scale-moves of gause (Iow)
reach vacuum condition in a moment, check again.
Vacuumize for over 15min.And check the level gauge
which should read -0.1 MPa (-76 cm Hg) at Iow
pressure side.After the completion of vacuumizing,
close the handle 'Lo' in gaugemanifold and stop the
operation of the vacuum pump.
Check the condition of the scale and hold it for 1-2min.
If the scale-moves back in spite of tightening, make
flaring work again, the return to the beginning of .
Open the valve rod for the 2-way valve to an angle of
anticlockwise 90 degrees.
After 6 seconds, close the 2-way valve and make
the inspection of gas leakage.
No gas leakage? In case of gas leakage, tighten
parts of pipe connection. If
leakage stops, then proceed
steps.
Detach the charge hose from the service port, open
2-way valve and 3-way.Turn the valve rod anticlockwise
until hitting lightly.
To prevent the gas leakage, turn the service port's
cap, the valve rod's cap for 2-way valve and 3-way's
a little more than the point where the torque increases
suddenly.
After attaching the each caps, check the gas leakage
around the caps.
CAUTION:
1.If the refrigerant of the air conditioner leaks, it is necessary to
discharge all the refrigerant.Vacuumize first, then charge the liquid
refrigerant into air conditioner according to the amount marked on
the name plate.
2.Please do not let other cooling medium, except specified one (R410A),
or air enter into the cooling circulation system.Otherwise, there will be
abnormal high pressure in the system to make it crack and lead to
personal injuries.
If it does not stop gas leakage, discharge
whole refrigerants from the service port.
After flaring work again and vacuumize,
fill up prescribed refrigerant from the gas
cylinder
