Installing the Remote Controller
● If the remote controller is to be installed onto a wall or
other surface for use, first place the remote controller in the
location where it will be installed and press
Confirm that the "signal-received" sound occurs at the indoor
unit and that the A/C begins operating.
Fasten the remote control
mount with screws.

● Installing the batteries
(1) Press on both sides of the remote controller cover and
slide it downward to remove it.
(2) Insert 2 AAA alkaline batteries. (Pay attention to the + and
– directions.)
(3) Gently insert one end of an unfolded paper clip (or a
similar object that can fit) into the Reset hole and press the
reset button inside the hole and then put the cover back
on.
To remove the remote controller, pull it toward you.
Precautions for remote controller installation
● Before mounting the remote controller on the wall, place the
unit at the mounting position, then turn on any fluorescent
lamps, press the ON/OFF button, and check that the air
conditioner operates correctly.
When using the remote controller to detect the room
temperature, observe the following precautions during
installation:
• Avoid locations where the remote controller will be exposed
to the direct path of air blown from the air conditioner.
• Avoid locations where the remote controller will be exposed
to direct sunlight.
• Avoid locations where the remote controller will be exposed
to direct heat sources.

10-27. Caution for Pump Down
Pump down means refrigerant gas in the system is returned
to the outdoor unit. Pump down is used when the unit is to be
moved, or before servicing the refrigerant circuit.
CAUTION
● This outdoor unit cannot collect more than the rated
refrigerant amount as shown by the nameplate on the
back.
● If the amount of refrigerant is more than that
recommended, do not conduct a pump down. In this
case use another refrigerant collecting system.
Caution on Pump Down (Refrigerant
Recovery)
Note: Pump down cannot be performed when the tubing length
exceeds 30m. (There is a possiblilty of generating the actuation
of the excessive load protection system.) In this case, collect
the refrigerant by the refrigeant collecting system.
1. Stop the unit operetion (cooling heating wind direction, etc.).
2. Connect the manifold gauge to the service port of the gas
tube service valve.
3. Short-circuit the PUMP pin on the outdoor unit control PCB
for over 1 second.
• Refrigerant recovery will start and the unit starts driving.
• During the refrigerant recovery. LED1 blinks and LED2
lights up on the outdoor unit control PCB.
• Remote control display shows
4. Fully close the liquid tube service valve after 2 or 3 minutes.
Pump down will start.
5. When the manifold gauge reduces to 0.2 - 0.1MPa. fully
close the gas tube service valve. Then again short-circuit the
PUMP pin (CN048). Refrigerant recovery is finished.
• If operation is continued for over 10 minutes, the unit stops
even if the refrigerant recovery is not completed. Check the
liquid tube service valve closed.
• When the PUMP pin (CN048) is shorted again during
refrigerant recovery the unit stops.
* For protection of the compressor do not drive until the unit
tubing side becomes negative pressure.

PUMP pin (CN048) is located
on the outdoor PCB as shown.
CAUTION
Pay much attention to
the fan of the outdoor
unit as there is danger
of injury during
operation.
