4. Evacuate air from the heater. Press the valve
until oil is leaking.
G09787s1
5. When the oil starts to flow through the
separator the counter pressure will increase and
regulation starts.
The counter pressure is increased to the latest
set value ±10%.
If the counter pressure does not reach 55 kPa
within one minute the pump will stop. See
8.3
Pump stops on page 49
6. To restart the feed pump, acknowledge alarm
and tap start button.
NOTE
Make sure that oil is available when starting the pump.
Running dry for a longer period can damage the pump.

7. When oil starts to flow through the pump the
counter pressure will increase.
NOTE
If the counter pressure is higher, this could indicate that
the return hose is connected to a pressurized system
with excessively high counter pressure. This is not
permitted. The safety function of the pressure switch
will be overridden allowing the pump (and heater if
mounted) to operate without flow.
NOTE
If the separator stops during this sequence (normally
because power consumption too high), see
8.5
Separator stops on page 50
