** 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.

TIPS FOR SAVING ENERGY
3
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.

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
refrigerant piping which has an excellent
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 insulation material according to the following procedure:

- Heat insulation material to be prepared...
Adiabatic EPDM or NBR with thickness 10 to

- Stick glass wool on all air conditioners that
are located in ceiling atmosphere.
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. (Remove screws ¿)
- Use the cord clamper to fix the cord.
! CAUTION
The supplied flexible drain hose should not
be curved, neither screwed. The curved or

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.
Connect same thickness
wiring to both sides.
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.

ENGLISH
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 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.

NOTE
1. The above table shows the correlation between the air rates and E.S.P.
2. Be sure to set the value refering table 1. Unexpected set value will cause mal-function.
3. Table 1 is based at 230V. According to the fluctuation of voltage, air flow rate varies.

* Because remote controller turn off when occur ERROR in simultaneous operation system, it
should check LED blinks of outdoor in order to confirm error code.
* Repeatedly after LED1 is turned on and off as the Error code number of tens digit, LED2 is
turned on and off as the Error code number of single-digit.
