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.

Limiting concentration is the limit of Freon gas

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.

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.

HEAT INSULATION
- Use the heat insulation material for the

heat-resistance (over 120°C).
- 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

Flaring Work
Putting nut on
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
Cut the pipes and the cable
- 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)
Flare nut
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.

Burrs removal
1. Completely remove all burrs from the cut

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.

- 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.
- Install the product so as not to make a gap with the wall side and to prevent shaking after the
installation.
Can set up Wired remote controller cable into three directions.
- Setup direction: the surface of wall reclamation, upper, right
- If setting up remote controller cable into upper and right side, please set up after removing

! CAUTION
When installing the wired remote controller, do not bury it in the wall. (It can cause damage in

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.
REMOTE CONTROLLER INSTALLATION 21
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 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.

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.
! CAUTION
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?

M6......245N.cm{25kgf.cm}
M8......588N.cm{60kgf.cm}
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.
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).
• 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)
- To cancel the test run, press any button.
