9-23. 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 blinks.
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.

■ Troubleshooting
If your air conditioner does not work properly, first check the
following points before requesting service. If it still does not
work properly, contact your dealer or a service center.

not work.)
■ Tips for Energy Saving
Avoid
●
Do not block the air intake and outlet of the unit. If either
is obstructed, the unit will not work well, and may be
damaged.
●
Do not let direct sunlight into the room. Use sunshades,
blinds or curtains. If the walls and ceiling of the room are
warmed by the sun, it will take longer to cool the room.
Do
● Always try to keep the air filter clean. (Refer to "Care and
Cleaning".) A clogged filter will impair the performance of the
unit.
● To prevent conditioned air from escaping, keep windows,
doors and any other openings closed.
NOTE
Should the power fail while the unit is running
If the power supply for this unit is temporarily cut off, the unit will
automatically resume operation once power is restored using
the same settings before the power was interrupted.
