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
