How to drain hoses and heater
It is possible to drain the heater and the hoses (not the hoses from pump to separator and from
separator to tank) by switching them in following way:
1. Stop the unit.
2. Set the unit in Manual mode, P6.
3. Switch the hoses fitted at the pump outlet (1)
and inlet (2).
4. Start the unit.
5. When the pump is started press the bleeding
valve (3) to allow air to enter the heater.
The heater and the hoses will be drained. If
possible check the oil flow.
If there is still oil in the system when the pump is
stopped after one minute start the system again.
Stop the system when the heater is drained.
NOTE
Switch back the hoses after draining.
