8.15 Restart
To ensure the SPU Mini is in good working order after a prolonged period of
maintainance the following steps should be taken.
1. Inspect the SPU Mini for signs of damage.
2. Check SPU Mini 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 SPU Mini 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 SPU Mini.
7. Turn on the mains electrical power and ensure both (if fitted) pumps can
run (use test pump option P6 if needed) and are pumping water to drain.
8. Close the drain valve and allow the SPU Mini to build pressure; the SPU
should turn off as the isolation valve to the system is closed.
9. Open the SPU outlet isolation valve and monitor the SPU Mini to ensure
there is no leaks as the system pressure increases.
10. Check all the pre set values on the SPU, to ensure they are still suitable for
the system (after maintainance/modification)
