8.2.1.6.Low Pressure Prevention Control (Gas Leakage Detection)

a. Control start conditions

Control will perform when (1) - (3) condition continues operation for 5 minute and (4) is fulfill.

1.During cooling and dry operation: Frequency more than normal Fcmax 78 Hz (E15D), 86 Hz (E18D), 102 Hz (E21D).

During heating operation: Frequency more than normal Fh 71 Hz (E15D), 86 Hz (E18D), 92 Hz (E21D).

2.Outdoor total current I cooling: IbIIa

Heating: IbIIc Ic = Ia = 1.65 A Ib = 0.65 A

3.It is not during deice operation.

4.During cooling and dry operation: indoor suction-indoor piping temperature is below 4°C.

During of heating operation: Indoor piping temperature-indoor suction is under 5°C. Control contents:

compressor stops (restart after 3 minutes)

if happen 2 times within (20 minutes), perform the following operation

1)Unit stop operation

2)Timer LED blink and “F91” indicated

8.2.1.7.Low Frequency Protection Control 1

When the compressor operate at frequency lower than 25 Hz continued for 20 minutes, the operation frequency will be increased to 24 Hz for two minutes.

8.2.1.8.Low Frequency Protection Control 2

When all the below conditions occur, minimum value (Freq. MIN) for the frequency instructed to compressor will change to 30 Hz for cooling mode operation and 20 Hz for heating mode operation.
