8.14 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 unit.
2. Isolate the unit from the system and vent excess pressure to drain.
3. Run the unit to pump excess water from the tank to drain.
4. Isolate the electrical supply from the unit.
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 unit cannot freeze . Damage will occure 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 unit.
8.15 Restart
To ensure the unit is in good working order after a prolonged period of
maintainance the following steps should be taken.
1. Inspect the unit for signs of damage.
2. Check unit 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 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 unit.
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 unit to build pressure; the unit should
turn off as the isolation valve to the system is closed.
9. Open the unit outlet isolation valve and monitor the unit to ensure there is
no leaks as the system pressure increases.
10. Check all the pre set values on the unit to ensure they are still suitable for
the system (after maintainance/modification)
