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.

* Apply enclosed noncombustible conduit(metal raceway) totally or use FT-6
rated cable or above level in case of
local electric & building code that requires plenum (CMP) cable usage.
2) When connecting Terminal Blocks of the indoor C/BOX and the wired remote controller with the extension cable, refer to the
steps below.
① Remove the screw on the cable which is
fastened to the wired remote controller’s
Terminal Block by loosening with a screw
driver.
② Remove the housing of the provided 32ft
extension cable with a cutting nipper and
peel it as shown in the figure below. (when

④ Please connect the Terminal blocks of indoor unit’s C/BOX and wired remote controller by referring to the images and
contents shown below.
Connect the yellow(signal) part of the wired
remote controller’s terminal block and the
‘YL’ part of the indoor unit’s terminal block.
Connect the red(12V) part of the wired remote controller’s terminal block and the

* In case of loosened screws or insufficient
contact between the terminal and the wire,
remote controller may not function properly.
* When the power is off on the remote controller, check the connection between the
remote controller and Terminal Block.
* Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with
a small head will strip the head and make
proper tightening impossible.
* Over-tightening the terminal screws may
break wires and terminal block structure.
INSTALLATION INSTRUCTION
• Installation work must be performed in
accordance with the national wiring standards and local by
authorized personnel only.
• Installations must comply with the applicable local/national or international standards.
• AWG#22, 3 core shielded is recommended when using the large hole in the
center of the back plate.
• AWG#24, 3 core shielded is recommended when using the side or top
knock-out of the back plate.
5 Please use an extension cable if the distance between the wired remote controller
and the indoor unit is longer than
32ft(10m).
! 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 164ft(50m) or
longer. (It can cause communication error.)
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 LCD.
