PUMP-DOWN
The unit is integrated with “PUMP-DOWN”
funcon. PUMP-DOWN funcon keeps compressor
running for
certain me to protect compressor and other crucial
parts before the unit or compressor is turned o.
PUMP-DOWN funcon acvates,
- When the unit reaches target temperature
- In between cooling mode to heang mode
- In between cooling mode to Fan only operaon
The unit operates in this parcular way to protect the
internal parts.
During PUMP-DOWN cycle, the compressor and fans
will be keep operang even though user turns o the
unit or turns o the compressor.
Please do not forcefully switch o the unit or
compressor during PUMP-DOWN cycle. The unit or

SELF-DIAGNOSTIC CODES (See Table 1)
The alarm light is acvated if abnormal operaon occurs, and a code is displayed on the control
panel. The compressor and condenser fan motor will stop operang. The evaporator fan will con-
nue to run for 3 minutes. If the fault is reced within 3 minutes, the unit will resume opera-
on. If the fault persists for more than 3 minutes, the evaporator fan also stops. The fault must
be reced before the unit can resume normal operaon.
