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)
High pressure 2.0~3.5MPa
Indoor 18~32°C
Outdoor 25~35°C
Low pressure 0.6~1.0MPa
Heating
(at max. frequency)
High pressure 2.2~2.8MPa
Indoor 15~25°C
Outdoor 5~10°C
Low pressure 0.3~0.8MPa
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
6. Refrigerant automatic recall operating instructions
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.
