• 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 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.

• 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

Do not connect the screws on Front and Rear side, it may cause the filter can not be mounted.
- Position unit on plenum or other suitable foundation.
- If the unit on plenum, make holes in plenum. Return air duct should be connected through
holes. Plenum should be connected in the unit using each 3 screws on the left and right side.
- After the duct is secured, seal around the supply duct to prevent air leakage. The filter access
must remain unobstructed.
- If plenum is not used, a frame strong enough to support the total weight must be provided.
- Provide a minimum height of 14 inches (350 mm) for proper unrestricted airflow.
- Vibration isolators (purchased locally) must be placed between the unit and pedestal.

Duct work
- Over 10 screws should be used for joining supply duct with the unit.
- To prevent vibration transmission, exploit flexible connectors between duct and the unit. It is
mandatory that the flexible connector between unit and duct at discharge connection should be
made off heat resistive material when electric heater is installed.
- Duct work must be insulated and covered with vapor barrier when routed through
unconditioned space.
- Internal acoustical insulation lining may necessary for the metal duct system if it do not have
90° elbow and 10 ft. of main duct to first branch takeoff.
- It is advised that a fibrous duct work could be used as a substitute if built and installed in
accordance with the most recent edition of SMACNA construction standard on fibrous glass
ducts.
- Collectively fibrous duct work and acoustical lining shall obey National Fire Protection
Association standards 90A or B as tested by UL standard 181 for class 1 air ducts.
- Seal around the delivery duct subsequent to when the duct is secured so that to facilitate
prevention of air leakage.

* Note 1) General location: When the pipe passes through indoors in which the indoor unit is
operated
- Apartment, classroom, office, mall, hospital, office-tel etc.
Note 2) Special location
1. When the location is air conditioned but has severe temperature/humidity difference
due to high ceiling
- Church, auditorium, theater, lobby etc.
2. When the location is air conditioned but the internal temperature/humidity of the
ceiling finishing is high
- Bathroom/swimming pool locker room etc. (Building with roof ceiling of sandwich
assembly type)
Note 3) General location: When the pipe passes indoors where the indoor unit is not operated
- Hall way etc. (Dormitory, school, office-tel)
Note 4) Negative condition: When below conditions 1 and 2 are met.
1. When the pipe passes indoors where the indoor unit is not operated
2. When the humidity is high, regionally, and there is no air flow in the pipe passing
area
- When installing the outside unit within the outside pipe tray or at a location where it
is ok to have freezes, apply 13 t.
- If you are not sure with the selection of heat insulation material, coordinate with the
supervision or HQ.
- The thickness of the above heat insulation material is based on the heat conductivity
of 0.088 W/m°C.
Condensate Drain
- The drainage performance has to be optimized by installing both primary and secondary drain
lines along with properly sized condensate traps in order to prevent property damage.
- Care should be taken to avoid the blocking of filter access panel while connecting condensate
drain lines. The primary and secondary condensate traps has to be primed after connecting to
the drain pan.
- A field supplied external condensate pan has to be installed underneath the entire unit if the
unit is above the living space . Other wise damage may result due to condensate over flow.
Also a additional external condensate line should run from unit in to the pan.
- The entire condensate should be drained from the external condensate pan to some noticeable
area. It is advised to install traps in condensate lines as near to the coil as possible. The outlet
of each trap should be below its connection to the condensate pan avert condensate from
overflowing drain pan.
- If located above the living area then all traps should be prime and insulated and also tested for
leakage.
- PVC 3/4 inch(19.05 mm) male pipe thread fitting is advised to use at condensate pan with
gentle tight.
- For easy drain flow the drain hose has to be pointed downward.
- Care should be taken to not use pipe joint connection or PVC/CPVC for units drain line
connection. Use only Teflon tape.
- For preventing winter freeze up on condensate line special means should be provided for
drainage.

NOTE
!
• Separately wire power supply cord and connecting cable.
• Use heat-proof electrical wiring capable of withstanding temperature up to 75 °C(167 °F).
• Use outdoor and waterproof connection cable NRTL(UL, ETL, CSA...) listed and rated more
than 300 V for the connection between indoor and outdoor unit. and this cable should be
enclosed in conduit.
After the confirmation of the above conditions, prepare the wiring as follows:
1Never fail to have an individual power specialized for the air conditioner. As for the
method of wiring, be guided by the circuit diagram pasted on the inside of control box
cover.
2Provide a circuit breaker switch between power source and the unit.
3The screw which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of transportation.
Check them and make sure that they are all tightly fastened. (If they are loose, it could
give rise to burn-out of the wires.)
4Specification of power source
5Confirm that electrical capacity is sufficient.
6Be sure that the starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
7Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8Never fail to equip a leakage breaker where it is wet or moist.
9The following troubles would be caused by voltage drop-down.
- Vibration of a magnetic switch, damage on the contact point there of fuse breaking,
disturbance to the normal function of a overload protection device.
- Proper starting power is not given to the compressor.

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 LCD. display. For proper display of the remote controller
LCD's, the remote controller should be installed properly as shown in Fig.1.
