Fixing of 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.

Indoor Unit Selection of Installation Place Outdoor Unit
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 and warm 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.
Place, which is less affected by rain or direct sunlight and is
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 with enough space for smooth air flow.
The air conditioner should not be installed on the
unprofessional metal frame (f.g. guard against theft net)
The outdoor unit should be installed above the ground
2.5m beside the street.
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
equivalent insulation material.
The thickness of the pipe must be 0.8 mm at least.

For preventing overturn, fasten the upside of the indoor unit onto the wall
with the anti-fall components and downside part on the floor with L shape
component. Please install the whole unit horizontally and keep the unit
pitch within 1 degree.
( 3 ) Fasten the indoor unit
( 2 ) Making a wall hole
Make a hole , with a little slope towards outside.Install
piping hole cover and seal it off with putty after installation.
(1 ) Position of the wall hole
Wall hole should be decided according to installlation
place and piping direction.(refer to installation drawings).

L component installation
Fasten the component onto the wall (fig. 1)
Keep the unit vertically and adjust the hole of the component,
and keep it unite with the unit tightly; then fasten the bolt (fig. 2)
Do not make gap between the component and the unit, fasten the L-shape component with the unit with the bolts (fig. 3).
After making sure the unit keeps vertical, fasten the L-shape onto the floor with the bolts (fig. 4).

(1) Remove the valve cap on 2-way valve in outdoor unit.
(2) Loosen by 1~2 circle the flare nut of gas pipe,
which is conneted to 3-way valve.
(3) Loosen 2-way valve by 90ousing hexagon wrench,
and after approx. After approx 15 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 additional refrigerant is necessary, first purge air out of connecting pipe by external gas,
then drive out the excessive refrigerant by purging method.
Brand new unit is charged 80g more refrigerant than regulated werght. This is only for first installation
to purge air in the indoor unit and connecting pipe.
and piping as followes:
Purging method
Push the air out of the indoor unit
