QUICK GUIDE TO POWER FLUSHING WITH A JETFLUSH RAPID PUMP
1 If system is vented, cap off the cold feed and
expansion pipe.
2 Couple JetFlush Rapid pump into system.
Connect dump, water inlet, and overflow hoses to
JetFlush Rapid pump.
3 Open all radiator and lock-shield valves, and set
zone valves to manual position, for full flow
throughout system.
4 Switch on JetFlush Rapid pump, and circulate for
10 minutes, reversing flow regularly.
5 Start dumping. Adjust inlet water to ensure tank
water level remains constant. Allow to run until
dump water is clear.
6 Set JetFlush Rapid into circulation mode, with
full flow through whole system (all radiator
valves open).
7 Pour Sentinel X800 Fast Acting Cleaner flushing
chemical into JetFlush Rapid tank.
8 If possible, switch on boiler to heat water to 50°C.
Don’t leave boiler firing continuously.
9 Continue circulation through wide open system
for 15 minutes, reversing flow regularly.
10 Shut off all radiator valves except for one radiator.
Allow full flow through this one radiator for 5
minutes, reversing flow regularly.
11 Shut off first radiator, and move to second. Work
around system, putting full flow through each
radiator in turn.
12 After circulating through last radiator, switch to
dumping on that one radiator, until water runs
clear.
13 Operate flow reverser and appropriate valves to
dump with water flow in opposite direction, until
water runs clear.
14 Open up previous radiator, and dump on that until
water runs clear. Work around system in reverse,
dumping through each individual radiator in turn.
15 Restore circulation through JetFlush Rapid
pump and complete heating system (all radiator
valves open).
16 Commence final dump procedure, with all
radiators wide open. Allow to run until dump
water is clear.
17 Test that dump water is neutral, with pH paper,
and add Sentinel X100 Inhibitor to JetFlush
Rapid tank.
18 Circulate for 10 minutes before disconnecting
JetFlush Rapid, restoring system to normal
operation, and bleeding radiators.
