e. Oil heater
A UL approved 150W oil heater has been installed in every compressor as a standard accessory.
Before restart of compressor after shutdown for a long time, please turn on oil heater at least 8 hours to make the
temperature inside compressor higher than system temperature and ambient temperature and then it can prevent
condensation of refrigerant inside oil sump of compressors which may result in liquid compression in next start and
poor lubrication due to too low viscosity of lubrication oil. In addition, Hanbell also offers 300W oil heater to keep
adequate lubricant oil temperature for large external oil separator and applications in areas with low ambient
temperature.

Specification
：
150W, 300W; 110V or 220V; IP 54; UL approval
Note: If the compressor is installed in low ambient temperature, it is recommended to insulate oil separator against cold
ambience.
f. Oil level switch
There are 2 wires for the interlock to main control circuit or any micro controller’s independent circuit. To prevent from
oil level switch trip caused by oil foaming or surging in the sump, a time delay around 15 seconds is recommended
before shut down the compressor.
Max. contact capacity = 50W/SPST
Surge current = 0.5A
Max. voltage = 200V DC/ 240V AC
Max. current = 1A
