Low pressure safety (Auto reset)
The low pressure safety switch is recommended to avoid
compressor operat i on at too lower suction pressure and
vacuum conditi on. The low pressure safety cut should never
be set below value as shown in the following table.
* M: Medium temperature; L: Low temperature
The low pressure cut off pressure is the setting of cut in
minus the differential .
3.9 Fan speed controller setting
The fan speed control l er regulates the speed of the
condenser’s f an.
It keeps the condensing pressure at a steady level by
changing the speed of the fan according to the required
condensing press ure.

Important No te
There must be no more than 10 compressor starts per
hour. A higher number reduces the
service life of the
compressor. If necessary, use an anti-short-cycle timer in
the control circuit. Minimum a 2 minute runtime after each
start of compressor and a 3
minute idle time after each
stop & start are
recommended. Only during the pump
down cycle may the compressor
run for much shorter
intervals.
