Here are some tips that will help you minimize the power consumption
when you use the air conditioner. You can use your air conditioner
more efficiently by referring to the instructions below:
• Do not cool excessively indoors. This may be harmful for your health
and may consume more electricity.
• Block sunlight with blinds or curtains while you are operating the air
conditioner.
• Keep doors or windows closed tightly while you are operating the air
conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate
indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period
of time.
• Open windows regularly for ventilation as the indoor air quality may
deteriorate if the air conditioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected
in the air filter may block the air flow or weaken the cooling / dehumidifying functions.

OUTDOOR UNITS INFORMATIONINSTALLATION PROCESS
CAUTION
!
• Ratio of the connectable Indoor Units to the Outdoor: 50 ~ 160%
• Ratio of running Indoor Units to the Outdoor: 10 ~ 100%
• A combination operation over 100% cause to reduce each indoor
unit capacity.
ALTERNATIVE REFRIGERANT R410A
The refrigerant R410A has the property of higher operating pressure in
comparison with R22.
Therefore, all materials have the characteristics of higher resisting
pressure than R22 ones and this characteristic should be also considered during the installation.
R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone
depletion potential (ODP) of R410A is 0.
CAUTION
!
• The wall thickness of the piping should comply with the relevant
local and national regulations for the designed pressure
3.8MPa(551.1psi).
• Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state.
If the refrigerant is charged in its gaseous state, its composition
changes and the system will not work properly.
• Do not place the refrigerant container under the direct rays of the
sun to prevent it from exploding.
• For high-pressure refrigerant, any unapproved pipe must not be
used.
• Do not heat pipes more than necessary to prevent them from
softening.
• Be careful not to install wrongly to minimize economic loss
because it is expensive in comparison with R22.
CAUTION
!
• The above list indicates the order in which the individual work operations are normally carried out but this order may be varied where
local conditions warrants such change.
• The thickness of the piping should comply with the relevant local
and national regulations for the designed pressure 3.8MPa(551.1psi).
• Since R410A is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state.(If the refrigerant is
charged in its gaseous state, its composition changes and the system will not work properly.)

Seasonal wind and cautions in winter
• Install correctly with the prospect of snow or cold temperatures in
mind.
• Install the outdoor unit ideally not to come into contact with snow directly. If snow piles up it will freeze to the heat exchanger, and the
system will malfunction. Attach a snow hood to prevent any issues.
• The raised support platform must be high enough to allow the unit to
remain above possible snow drifts, and must be higher than the maximum anticipated snowfall for the location.
• Remove any snow that piles higher than 100mm on the top of the
unit.
- In areas of high wind, do not install the units heat exchanger or discharge fan perpendicular to the wind direction.
Air guide work
In cases where the outdoor unit is installed in an enclosed space, care
should be taken to ensure adequate airflow around the product, otherwise failure could occur.
• The operating ratio should be at least 80%
• Louver angle should be 0~20 degree

If the support strength is not enough, the outdoor unit may drop
and hurt people.
• Install where the outdoor unit may not fall in strong wind or
earthquake.
If there is a fault in the supporting conditions, the outdoor unit
may fall and hurt people.
• Please take extra cautions on the supporting strength of the
ground, water outlet treatment(treatment of the water flowing
out of the outdoor unit in operation), and the passages of the
pipe and wiring, when making the ground support.
• Do not use tube or pipe for water outlet in the Base pan. Use
drainage instead for water outlet. The tube or pipe may freeze
and the water may not be drained.
CAUTION
!
• Be sure to remove the Pallet(Wood Support) of the bottom
side of the outdoor unit Base Pan before fixing the bolt. It
may cause the unstable state of the outdoor settlement,
and may cause freezing of the heat exchanger resulting in
abnormal operations.
• Be sure to remove the Pallet(Wood Support) of the bottom
side of the outdoor unit before welding. Not removing Pallet(Wood Support) causes hazard of fire during welding.
Preparation of Piping
Main cause of gas leakage is defect in flaring work. Carry out correct
flaring work in the following procedure.
Cut the pipes and the cable
- Use the accessory piping kit or the pipes purchased locally.
- Measure the distance between the indoor and the outdoor unit.
- Cut the pipes a little longer than measured distance.
- Cut the cable 1500mm(59-1/16inch) longer than the pipe length.
Burrs removal
- Completely remove all burrs from the cut cross section of pipe/tube.
- Put the end of the copper tube/pipe to downward direction as you remove burrs in order to avoid to let burrs drop in the tubing.
Flaring work
- Carry out flaring work using flaring tool as shown below.

Precautions when connecting pipes
- See the following table for flare part machining dimensions.
- When connecting the flare nuts, apply refrigerant oil to the inside and
outside of the flares and turn them three or four times at first. (Use
ester oil or ether oil.)
See the following table for tightening torque.(Applying too much torque may
cause the flares to crack.)
- After all the piping has been connected, use nitrogen to perform a
gas leak check.

• When loosening a flare nut, always use two wrenches in
combination, When connecting the piping,
always use a spanner and torque wrench
in combination to tighten the flare nut.
• When connecting a flare nut, coat the
flare(inner and outer faces) with oil for
R410A(PVE) and hand tighten the nut
3 to 4 turns as the initial tightening.
Opening shutoff valve
1 Remove the cap and turn the valve counter clockwise with the
hexagon wrench.
2 Turn it until the shaft stops.
Do not apply excessive force to the shutoff valve. Doing so may
break the valve body, as the valve is not a backseat type. Always
use the special tool.
3 Make sure to tighten the cap securely.
Closing shutoff valve
1
Remove the cap and turn the valve clockwise with the hexagon wrench.

Use the heat insulation material for the refrigerant piping which has
an excellent heat-resistance (over 120°C).
2 Precautions in high humidity circumstance:
This air conditioner has been tested according to the "ISO Conditions with Mist" and confirmed that there is not any default. However, if it is operated for a long time in high humid atmosphere
(dew point temperature: more than 23°C), water drops are liable to
fall. In this case, add heat insulation material according to the following procedure:
- Heat insulation material to be prepared... EPDM (Ethylene Propylene Diene Methylene)-over 120°C the heat-resistance temperature.
- Add the insulation over 10mm thickness at high humidity environment.

Nitrogen substitution method
Welding, as when heating without nitrogen substitution a large
amount of the oxide film is formed on the internal piping.
The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor.
It prevents normal operation of the compressor.
In order to avoid this problem, Welding should be done after replacing
air by nitrogen gas.
When welding plumbing pipe, the work is required.
