Refrigerant Automatic Recall Operating Instructions; Temp. Difference Between Air Inlet And Air Outlet Standard; Running Current Standard; Running Pressure Standard - Haier AV08NMSETA Service Manual

Note 1:

Temp. difference between air inlet and air outlet Standard

• A. In cooling mode, after running for at least 30 minutes, it is normal that the temp. difference between air inlet
and air outlet is over 10°C, (at max. frequency)
• B. In heating mode, after running for at least 30 minutes, it is normal that the temp. difference between air inlet
and air outlet is over 14°C, (at max. frequency).
Note 2:

Running current standard

• It is normal that the running current is in the range of rated current 15±% (at max. frequency) . The current will be
different for the below condition:
• If more than the rated current: high indoor/outdoor temp. ; outdoor bad ventilation (cooling mode), indoor bad
ventilation (heating mode).
• If lower than rated current: low indoor/outdoor temp. ; refrigerant leakage (lack of refrigerant).
Note 3:

Running pressure standard

Cooling
(at max. frequency)
Heating
(at max. frequency)
The above value is measured after running for 15 minutes (ambient temp. is DB(°C))
High/low pressure changing trend due to the running condition:
Cooling/heating:
Indoor temp. goes up---high/low pressure goes up
Indoor temp. goes down---high/low pressure goes down
Outdoor temp. goes up---high/low pressure goes up
Outdoor temp. goes down---high/low pressure goes down

Please according to as follows the operation
1. Press"start+stop" at the same time on the PCB 5 ses,
2. When the digital tube shows C1 alternately gleam with
low-pressure pressure, please close liquid valve; When
the digital tube shows C2, please close gas valve; The
system automatically shuts down after the 5 ses, the digital tube
shows C3, please cut the power.
