Long term isolation and restart procedure
If the system is to be shut down for an extended period of time due to
maintainance or system modifications being carried out to the system the
following steps must be taken .
1 . Isolate mains inlet water from the APU Midi .
2 . Isolate the APU Midi from the system and vent excess pressure to drain .
3 . Run the APU to pump excess water from the tank to drain .
4 . Isolate the electrical supply from the APU .
5 . Remove the vent screws on the front of the pumps and allow excess
water to drain . Replace vent screws . See section 6 .26 .
6 .
Ensure the pressurisation unit cannot freeze . Damage will occur to the pumps
if this is allowed to happen .
7 . Cover with plastic sheet or cardboard if work is to be conducted close to
the APU .
8 .15 Restart
To ensure the APU is in good working order after a prolonged period of
maintainance the following steps should be taken .
1 . Inspect the APU for signs of damage .
2 . Check APU tank for debris, remove debris and clean tank if needed . Debris
may cause damage to the pumps if it is allowed to be drawn in .
3 . Check pressure vessel pre charge pressures before the system pressure is
increased .
4 . Open the mains water isolating valve allowing the APU tank to fill, and
ensure the fill valve is operating correctly and maintaining the correct
water level .
5 . Check for signs of leakage .
6 . Open the drain valve on the outlet of the APU .
7 . Turn on the mains electrical power and ensure both (if fitted) pumps can
run (use test pump option if needed) and are pumping water to drain .
8 . Close the drain valve and allow the APU to build pressure; the pressurisation unit
should turn off as the isolation valve to the system is closed .
9 . Open the APU outlet isolation valve and monitor the APU to ensure there are
no leaks as the system pressure increases .
10 . Check all the pre set values on the APU to ensure they are still suitable for
the system (after maintainance/modification)
