TIPS FOR SAVING ENERGY
ENGLISH
TIPS FOR SAVING ENERGY
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.

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.
Always comply with the following precautions to avoid dangerous situations and ensure peak
performance of your product
! WARNING
It can result in serious injury or death when the directions are ignored
! CAUTION
It can result in minor injury or product damage when the directions are ignored
! WARNING
• Installation or repairs made by unqualified persons can result in hazards to you and others.
• Installation of all field wiring and components MUST conform with local building codes or, in
the absence of local codes, with the National Electrical Code 70 and the National Building
Construction and Safety Code or Canadian Electrical code and National Building Code of
Canada.
• The information contained in the manual is intended for use by a qualified service technician
familiar with safety procedures and equipped with the proper tools and test instruments.
• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, property damage, personal injury and/or death.
Installation
• Always perform grounding. - Otherwise, it may cause electrical shock.
• For installation of the product, always contact the service center or a professional installation
agency. - Otherwise, it may cause a fire, electrical shock, explosion or injury.
• Securely attach the electrical part cover to the indoor unit and the service panel to the outdoor unit.
- If the electrical part cover of the indoor unit and the service panel of the outdoor unit are not
attached securely, it could result in a fire or electric shock due to dust, water, etc.
• Always install an air leakage breaker and a dedicated switching board. - No installation may cause a
fire and electrical shock.
• Do not keep or use flammable gases or combustibles near the air conditioner. - Otherwise, it may
cause a fire or the failure of product.
• Ensure that an installation frame of the outdoor unit is not damaged due to use for a long time.
- It may cause injury or an accident.
• Do not disassemble or repair the product randomly. - It will cause a fire or electrical shock.
• Do not install the product at a place that there is concern of falling down. - Otherwise, it may result
in personal injury.
• Use caution when unpacking and installing. - Sharp edges may cause injury.
• 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.
• Consult your lacal dealer regarding what to do in case of refrigerant leakage.
When the air conditioner is to be installed in a small room, it is necessary to take proper measures
so that the amount of any leaked refrigerant does not exceed the concentration limit in the event of
a leakage. Otherwise, this may lead to an accident due to oxygen depletion.
• Carry out the specified installation work after taking into account earthquakes.
Failure to do so during installation work may result in the unit falling and causing accidents.

injury.
• Do not step on the indoor/outdoor unit and do not put anything on it. - It may cause an injury through
dropping of the unit or falling down.
• When the product is submerged into water, always contact the service center. - Otherwise, it may
cause a fire or electrical shock.
• Take care so that children may not step on the outdoor unit. - Otherwise, children may be seriously
injured due to falling down.
! CAUTION
Installation
• Install the drain hose to ensure that drain can be securely done. - Otherwise, it may cause water
leakage.
• Install the product so that the noise or hot wind from the outdoor unit may not cause any damage to
the neighbors. - Otherwise, it may cause dispute with the neighbors.
• Always inspect gas leakage after the installation and repair of product. - Otherwise, it may cause the
failure of product.
• Keep level parallel in installing the product. - Otherwise, it may cause vibration or water leakage.
Operation
• Avoid excessive cooling and perform ventilation sometimes. - Otherwise, it may do harm to your
health.
• Use a soft cloth to clean. Do not use wax, thinner, or a strong detergent. - The appearance of the air
conditioner may deteriorate, change color, or develop surface flaws.
• Do not use an appliance for special purposes such as preserving animals vegetables, precision
machine, or art articles. - Otherwise, it may damage your properties.
• Do not place obstacles around the flow inlet or outlet. - Otherwise, it may cause the failure of appliance or an accident.

Drain test
The air conditioner uses a drain pump to drain
water.
Use the following procedure to test the drain
pump operation:
- Connect the main drain pipe to the exterior
and leave it provisionally until the test comes
to an end.
- Feed water to the flexible drain hose and
check the piping for leakage.
- Be sure to check the drain pump for normal
operating and noise when electrical wiring is
complete.
- When the test is complete, connect the flexible drain hose to the drain port on the indoor
unit.

Indoor Unit Drain Piping
- Drain piping must have down-slope (1/50 to

slope to prevent reversal flow.
- During drain piping connection, be careful
not to exert extra force on the drain port on
the indoor unit.
- The outside diameter of the drain connection
on the indoor unit is 32mm(1-1/4 inch).
Piping material: Polyvinyl chloride pipe

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.

Wired remote controller installation
Since the room temperature sensor is in the remote controller, the remote controller box should
be installed in a place away from direct sunlight, high humidity and direct supply of cold air to
maintain proper space temperature. Install the remote controller about 5ft(1.5m) above the floor
in an area with good air circulation at an average temperature.
Do not install the remote controller where it can be affected by:
- Drafts, or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall behind the remote controller.
- This remote controller is equipped with LCD. display. For proper display of the remote controller
LCD's, the remote controller should be installed properly as shown in Fig.1.
(The standard height is 4~5 ft (1.2~1.5 m) from floor level.)
