• 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 condition-
er 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.

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:
TIPS FOR SAVING ENERGY
• Use caution when unpacking and installing.
- Sharp edges may cause injury.
• Thickness of copper pipes used are as shown “Flaring work” Table.
- Never use copper pipes thinner than that in the table even when it is available on the market
• Do not use copper pipes having a collapsed.
- Otherwise, the expansion valve or capillary tube may become blocked with contaminants.
• For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant.
- Using of (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant
cycle (piping), and possibly result in explosion and injury.
• It is desirable that the amount of residual oil less than 40 mg/10m.
• If air enters the refrigerant system, an excessively high pressure results, causing equipment dam-
age or injury.
• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant lev-
els may cause failure of product.
• Ensure that you grab the chassis when you lift the unit.
- If you lift the unit with the panel held, it may result in serious injury or product failure.
• Do not turn on the breaker or power under condition that front panel, cabinet, top cover, control box
cover are removed or opened.
- Otherwise, it may cause fire, electric shock, explosion or death.
• Make the connections securely so that the outside force of the cable may not be applied to the ter-
minals.
- Inadequate connection and fastening may generate heat and cause a fire.
• After pump down, power must be turned off before removing the pipe.
- When operating this product without connecting the pipe, there will be high pressure inside the
compressor due to the entry of air, possibly causing explosion or injury.
• If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant
concentration from exceeding the safety limit when the refrigerant leaks.
- Consult the dealer regarding the appropriate measures to prevent the safety limit from being
exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to
lack of oxygen in the room could result.
• Use a vacuum pump or inert (nitrogen) gas when doing leakage test or air purge. Do not compress
air or oxygen and do not use flammable gases.
- Otherwise, it may cause fire or explosion. There is the risk of death, injury, fire or explosion.
Operation
• Do not share the outlet with other appliances.
- It will cause an electric shock or a fire due to heat generation.
• Do not use the damaged power cord.
- Otherwise, it may cause a fire or electrical shock.
• Do not modify or extend the power cable.
- Scratches or peeling insulation on the power cables may result in fire or electric shock, and should
be replaced.

- Make sure that condensation drainage can
be conveniently routed away.
- Do not install near a doorway.
- Ensure that the interval between a wall and
the left (or right) of the unit is more than 4 in.
The unit should be installed as high as possi-
ble on the wall, allowing a minimum of 8 in.

and discharge sides (discharge side
obstacle is lower than the outdoor unit).
2 Where there are obstacles above, and on
both suction and discharge sides
(discharge side obstacle is lower than the

- Select a place where the warm air and noise
from the air conditioner do not disturb
neighbors.
- Sunroof is recommended for installations that
are exposed to direct sunlight and for
installations in cold climates with heavy snow
which can accumulate on top of outdoor unit.

- If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
- Ensure that the space around the back and
sides is more than 12 in. The space in front of
the unit should be more than 28 in. of space.
- Do not place animals and plants in the path of
the warm air.

Fixing Installation Plate
The wall you select should be strong and solid
enough to prevent vibration
1 Mount the installation plate on the wall
with type "A" screws. If mounting the unit
on a concrete wall, use anchor bolts.
- Mount the installation plate horizontally
by aligning the centerline using Horizontal
meter.
2 Measure the wall and mark the centerline.
It is also important to use caution concern-
ing the location of the installation plate.
Routing of the wiring to power outlets is
through the walls typically. Drilling the hole
through the wall for piping connections
must be done safely.
Drill a Hole in the Wall
- Drill the piping hole with a Ø2-9/16” hole
core drill. Drill the piping hole at either the
right or the left with the hole slightly slanted
to the outdoor side.
Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
Cut the pipes and the cable
1 Use the piping kit accessory or the pipes
purchased locally.
2 Measure the distance between the indoor
and the outdoor unit.
3 Cut the pipes a little longer than measured
distance.
4 Cut the cable 4.9 ft longer than the pipe
length.

into the tubing.
Putting nut on
- Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after finishing
flare work)
Flaring work
1 Firmly hold copper pipe in a bar with the
dimension shown in below table.
2 Carry out flaring work with the flaring tool.
Check
1 Compare the flared work with the figure
