supply plug or turn off the breaker.
- There is risk of product damage or failure, or unintended operation.
• Take care to ensure that nobody could step on or fall onto the outdoor
unit.
- This could result in personal injury and product damage.
CAUTION
!
Installation
• Always check for gas (refrigerant) leakage after installation or repair of
product.
- Low refrigerant levels may cause failure of product.
• Install the drain hose to ensure that water is drained away properly.
- A bad connection may cause water leakage.
• Keep level even when installing the product.
- To avoid vibration or water leakage.
• Do not install the product where the noise or hot air from the outdoor
unit could damage the neighborhoods.
- It may cause a problem for your neighbors.
• Use two or more people to lift and transport the product.
- Avoid personal injury.
• Do not install the product where it will be exposed to sea wind (salt
spray) directly.
- It may cause corrosion on the product. Corrosion, particularly on the
condenser and evaporator fins, could cause product malfunction or
inefficient operation.
Operation
• Do not expose the skin directly to cool air for long periods of time.
(Don't sit in the draft.)
- This could harm to your health.
• Do not use the product for special purposes, such as preserving foods,
works of art, etc. It is a consumer air conditioner, not a precision
refrigeration system.
- There is risk of damage or loss of property.
• Do not block the inlet or outlet of air flow.

ENGLISH
• Do not touch the metal parts of the product when removing the air
filter. They are very sharp!
- There is risk of personal injury.
• Do not step on or put anyting on the product. (outdoor units)
- There is risk of personal injury and failure of product.
• Always insert the filter securely. Clean the filter every two weeks or
more often if necessary.
- A dirty filter reduces the efficiency of the air conditioner and could
cause product malfunction or damage.
• Do not insert hands or other objects through the air inlet or outlet while
the product is operated.
- There are sharp and moving parts that could cause personal injury.
• Do not drink the water drained from the product.
- It is not sanitary and could cause serious health issues.
• Use a firm stool or ladder when cleaning or maintaining the product.
- Be careful and avoid personal injury.
• Replace the all batteries in the remote control with new ones of the
same type. Do not mix old and new batteries or different types of
batteries.
- There is risk of fire or explosion.
• Do not recharge or disassemble the batteries.
Do not dispose of batteries in a fire.
- They may burn or explode.
• If the liquid from the batteries gets onto your skin or clothes, wash it
well with clean water. Do not use the remote if the batteries have
leaked.
- The chemicals in batteries could cause burns or other health
hazards.
• If you eat the liquid from the batteries, brush your teeth and see doctor.

Limiting concentration is the limit of Freon gas concentration where immediate measures
can be taken without hurting human body when refrigerant leaks in the air. The limiting

Limiting concentration
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level and are not necessarily safe working levels.
Whilst there is a correlation between the emission and exposure levels, this cannot be
used reliably to determine whether or not further precautions are required.
Factor that influence the actual level of exposure of the workforce include the
characteristics of the work room and the other sources of noise, i.e. the number of
equipment and other adjacent processes and the length of time for which an operator
exposed to the noise. Also, the permissible exposure level can vary from country to
country.
This information, however, will enable the user of the equipment to make a better
evaluation of the hazard and risk.

Be sure to give insulation work to refrigerant piping by covering liquid pipe and gas pipe separately
with enough thickness heat-resistant polyethylene, so that no gap is observed in the joint between
indoor unit and insulating material, and insulating materials themselves. When insulation work is
insufficient, there is a possibility of condensation drip, etc. Pay special attention to insulation work to

u Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal block.
When none are available, follow the instructions below.
• Do not connect wiring of different thicknesses to the power terminal block. (Slack in the
power wiring may cause abnormal heat.)
• When connecting wiring which is the same thickness, do as shown in the figure below.
• For wiring, use the designated power wire and connect firmly, then secure to prevent
outside pressure being exerted on the terminal block.
• Use an appropriate screwdriver for tightening the terinal screws. A screwdriver with a
small head will strip the head and make proper tighterning impossible.
• Over-tightening the terminal screws may break them.
HAND OVER
Teach the customer the operation and maintenance procedures, using the operation manual.

like to setup.
- Please set it up not to bend because poor setup could take
place if setup board bends.
Please set up remote controller board fit to the reclamation
box if there is a reclamation box.

Wired remote controller installation
Fig.1 Typical locations for remote controller
•
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 5 ft(1.5 m) 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 a seven segment LED. display. For proper display of the remote
controller LED's, the remote controller should be installed properly as shown in Fig.1.
(The standard height is 1.2~1.5 m from floor level.)
4. Please connect indoor unit and remote controller using connection cable.
5. Please use extension cable if the distance between wired remote controller and indoor unit is more
than 10 m.
Please check if connector is normally connected.
Connecting cable
Indoor
Unit side
CAUTION
When installing the wired remote controller, do not bury it in the wall. (It can cause damage in the
temperature sensor.)
Do not install the cable to be 50m or above. (It can cause communication error.)
• When installing the extension cable, check the connecting direction of the connector of the remote
controller side and the product side for correct installation.
• If you install the extension cable in the opposite direction, the connector will not be connected.
• Specification of extension cable: 2547 1007 22# 2 core 3 shield 5 or above.
