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.

- Precautions in high humidity circumstance:
This air conditioner has been tested according to the "KS Standard Conditions with Mist"
and confirmed that there is not any default.
However, if it is operated for a long time in
high humid atmosphere (dew point temperature: more than 23 °C), water drops are liable
to fall. In this case, add heat insulation material according to the following procedure:
Fastening band
(accessory)
Indoor
unit
Refrigerant
piping
Thermal insulator
(accessory)
- Heat insulation material to be prepared...
Adiabatic EPDM or NBR with thickness 10 to
20 mm.
- Stick glass wool on all air conditioners that
are located in ceiling atmosphere.
- In addition to the normal heat insulation
(thickness: more than 8 mm) for refrigerant
piping (gas piping: thick piping) and drain
piping, add further 10 mm to 30 mm
thickness material.
Wiring Connection
- Open the control box cover and connect the
Remote controller cord and Indoor power wires.
- Remove the control box cover for electrical connection between the indoor and outdoor unit.
- Use the cord clamper to fix the cord.
Wired Remote
Controller Cord
(there is no need
in case of Wireless

HEAT INSULATION
- Use the heat insulation material for the
refrigerant piping which has an excellent
heat-resistance (over 120 °C).

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.

! CAUTION
The connecting cable connected to the
indoor and outdoor unit should be complied with the following specifications
(This equipment shall be provided with a
cord set complying with the national regulation).
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.

NORMAL
CROSS-SECTIONAL
AREA 0.75 mm2
Connect same thickness

If the supply cord is damaged, it must be
replaced by a special cord or assembly
available from the manufacturer of its
service agent.
! CAUTION
The Power cord connected to the unit
should be selected according to the following specifications.
It is forbidden to
connect two to one
side.
It is forbidden to
connect wiring of
different thicknesses.
- 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.

TEST RUNNING 13
ENGLISH
TEST RUNNING
PRECAUTIONS IN TEST RUN
- The initial power supply must provide at least
90 % of the rated voltage.
Otherwise, the air conditioner should not be
operated.
Connection of power supply
- Connect the power supply cord to the independent power supply.
Circuit breaker is required.
- Operate the unit for 15 minutes or more.
! CAUTION
• For test run, carry out the cooling operation firstly even during heating season.
If heating operation is carried out firstly,
it leads to the trouble of compressor.
Then attention must be paid.
• Carry out the test run more than 5 minutes without fail.
(Test run will be cancelled 18 minutes
later automatically)
Evaluation of the performance
- Measure the temperature of the intake and
discharge air.
- Ensure the difference between the intake
temperature and the discharge one is more
than 8 °C (Cooling) or reversely (Heating).
- To cancel the test run, press any button.
CHECK THE FOLLOWING ITEMS WHEN
INSTALLATION IS COMPLETED
- After completing work, be sure to measure
and record trial run properties, and store
measured data, etc.
- Measuring items are room temperature, outside temperature, suction temperature, blow
out temperature, wind velocity, wind volume, voltage, current, presence of abnormal
vibration and noise, operating pressure, piping temperature, compressive pressure.
- As to the structure and appearance, check
following items.
* Is the circulation of air adequate?
* Is the draining smooth?
* Is the heat insulation complete
(refrigerant and drain piping)?
* Is there any leakage of refrigerant?
* Is the remote controller switch operated?
* Is there any faulty wiring?
* Are not terminal screws loosened?
