Unit supplied with a holding charge of Helium, the refrigerant charge is suitable for upto10 metres of interconnecting pipework, additional refrigerant must be added for longer
pipe runs.
Adding Refrigerant
Refrigerant should be added to the system via 1/4” schrader connection on the expansion
line as required.
UNLOADING PROTECTION
Head Pressure
The microprocessor has inbuilt protection against nuisance trips. If the head pressure
rises above 23 barg the system will unload 1 compressor and remain unloaded until the
head pressure drops below 21 barg.
Low Pressure
If low pressure drops below the microprocessor setting, the compressor will unload to 1
compressor, if low pressure persists for 1 minute, the circuit will be switched off and
sound an alarm.
