5.3. Powering The Crankcase Heater
In order to ensure optimal oil temperature on startup, the compressor is equipped with a
crankcase heater and oil temperature sensor. To power this heater:
•
Check direction of fan to make sure the phase sequence is correct (fans should be
drawing air into the unit and exhausting colder air out through the top of the unit.). If the
coils have air coming out instead of in then the phases are wrong and two legs should
be swapped.
•
Close the main switch by turning it from OFF to ON
•
Check that “OFF” appears on the display
•
Make sure the unit domestic hot water demand
is “OFF” and that the external
enable/disable contact is open
•
Leave the machine in these conditions for at least 12 hours to power the crankcase
heater.
5.4. Potential Free Contacts
The following potential free contacts are available:
•
1 contact for the alarm relay
•
1 dry contact for compressor status
•
1 dry contact for enabling the domestic hot water pump
