1. Slowly open the steam motive supply and exhaust isolating valves (item 7) to provide
pressure to the MFP14-PPU. Check that the motive trap (item 9 where fitted) is operational.
2. Open any isolation valves between the process being drained and the MFP14-PPU at
points (Z).
3. Open the inlet isolation valve (item 5) and the condensate outlet isolation valve (item 5)
in the condensate return line (point V).
4. Condensate should now start to flow into the main receiver (item 1) and into the pump (item 3)
when the plant is operational.
5. Check all flanged/screwed connections for any leakage.
6. Observe operation for any abnormalities. The pump (item 3) should cycle periodically
(minimum cycle time is 8 seconds) with an audible exhaust at the end of the pumping cycle.
This can be used to monitor the operation of the unit and meter the volume of condensate
pumped. If any irregularities are observed, recheck Sections 4.1 and 4.2 for proper
arrangement. Consult Spirax Sarco if necessary.
7. The system is now operational.
