• 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
• 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.
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 cord randomly.
- Otherwise, it may cause a fire or electrical shock.
• Take care so that the power cord may not be pulled during operation.
- Otherwise, it may cause a fire or electrical shock.
• Unplug the unit if strange sounds, smell, or smoke comes from it.
- Otherwise, it may cause electrical shock or a fire.
• Keep the flames away.
- Otherwise, it may cause a fire.
• Take the power plug out if necessary, holding the head of the plug and do not touch it with wet
hands.
- Otherwise, it may cause a fire or electrical shock.
• Do not use the power cord near the heating tools.
- Otherwise, it may cause a fire and electrical shock.
• Do not open the suction inlet of the indoor/outdoor unit during operation.
- Otherwise, it may electrical shock and failure.

1
Completely remove all burrs from the cut
cross section of pipe/tube.
2
While removing burrs put the end of the
copper tube/pipe in a downward direction
while removing burrs location is also
changed in order to avoid dropping burrs
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 table
below.
2
Carry out flaring work with the flaring tool.
Check
1
Compare the flared work with the figure
by.
2
If a flared section is defective, cut it off
and do flaring work again.

1
Insert the connecting cable through the
bottom side of indoor unit and connect the
cable (You can see detail contents in
'Connecting the cables' section)
2
Secure the cable onto the control board
with the cable retainer.
3
Tape the tubing pipe, drain hose and the
connection cable. Be sure that the drain
hose is located at the lowest side of the
bundle. Locating at the upper side can
cause overflow from the drain pan through
the inside of the unit.

CAUTION
If the drain hose is routed inside the
room, insulate the hose with an insulation
material* so that dripping from "sweat-
ing"(condensation) will not damage furni-
ture or floors.
* Foamed polyethylene or equivalent is
recommended.
!
CAUTION
Ensure that you put the boss of the chas-
sis on the prop of the installation plate
and mate the hole of the chassis with the
hole of the installation plate.

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 Ø55mm 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.
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 1.5m longer than the pipe
length.
Cut the pipes and the cable
