Floor fixing dimensions
of the outdoor unit
(Unit:mm)
Fix the unit to concrete or block with bolts( 10mm) and nuts firmly and horizontally.
Fixing of outdoor unit
Indoor Unit
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.
Outdoor Unit
Selection of Installation Place
Place, robust not causing vibration, where the body can be supported
sufficiently.
Place, which is less affected by rain or direct sunlight and is
sufficiently ventilated.
Place, not affected by heat or steam generated in the vicinity, where
inlet and outlet of the unit are not disturbed.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, possible to drain easily, where piping can be connected with the
outdoor unit.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
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 a distance marked
in the above figure.
is available as illustrated
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.
Power Source
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.
Selection of pipe
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
Liquid pipe
Gas pipe
6.35mm(1/4")
9.52mm(3/8")
equivalent insulation material.
The thickness of the pipe must be 0.8mm at least.

3.Installation of the Indoor Unit
Drawing of pipe
Rear piping
Draw pipes and the drain hose, then fasten them with the adhesive tape
Left Left-rear piping
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

Fix with adhesive tape
Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.
Other direction piping
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.
Fixing the indoor unit body
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.
4.Connecting the indoor/outdoor Electric Cable
Removing the wiring cover
Remove terminal cover at right bottom corner of indoor unit, then
take off wiring cover by removing its screws.

Indoor unit
When connecting the cable after 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.
When connecting the cable before installing the indoor unit
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 H05/07RN-F or 245IEC57(YZW).
2. If the fuse on PC board is broken please change it with the type of T. 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.

1.Installation of Outdoor Unit
Drawing for the installation of indoor and outdoor units
Install according to
2.Connection of pipes
To bend a pipe, give the roundness as large as possible not to crush the pipe.
Connecting the pipe of gas side first makes working easier.
The max vertical distance between the indoor unit and the outdoor unit is 5 m.

3.Connection
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.
If wiring is not correct, proper operation can
not be carried out and controller may be
damaged.
Fix the cable with a clamp.
Insert the cable according to terminal number
in the same manner as the indoor unit.
4.Attaching Drain-Elbow

5.Purging Method:
Push the air out of the indoor unit
and piping as followes:
(1) Remove the valve cap on 2-way
valve in outdoor unit.
(2) Loosen by 1/2 turn the flare nut of
gas pipe, which is conneted to
3-way valve.
3-way valve
9.52mm(3/8")
12.7mm(1/2")
2-way valve

(3) Loosen 2-way valve by 90o using
hexagon wrench, and after approx.
10 sec tighten it up. Gas comes out
through flare nut on wide pipe. If no
gas is discharged, tighten flare nut
with specified torque.
(4) Open 2-way and 3-way valves
using specified torque.
(5) Tighten the caps on the valves
with specified torque.

Note: When extending piping, air inside piping shall be removed by using external
refrigerant gas, charge according to the following list.
Brand new outdoor unit is charged 50g more refrigerant than regulated weight.
Only for first installation, this extra 50g can be used to purge air in pipes.
During this procedure, 50g refrigerant will be discharged in piping.
(This must be strictly controlled within 90o and 10 sec.)

1.Power Source Installation
The power source must be exclusively used for air conditioner. (Over I0A)
In the case of installing an air conditioner in a moist place, please install an
earth leakage breaker.
For installation in other places, use a circuit breaker as far as possible.
2.Cutting and Flaring Work of Piping
Pipe cutting is carried out with a pipe cutter and burs must be removed.
After inserting the flare nut, flaring work is carried out.
