Fit the replacement body in reverse order
ensuring that the pump washers are sound and
fitted correctly and the polarity of the electrical
connections are correct.
Open the isolating valves on the low and return
connections, refill, vent and re-pressurise the
system ensuring all joints are sound.
19.11 Low water pressure sensor
Drain the boiler’s hydraulic circuit as detailed in
(19.2).
Remove the pressure sensor by turning it in an
anticlockwise direction.
Fit the replacement sensor in reverse order of
removal ensuring all washers are fitted. Replace
damaged washers as necessary.
Open the isolating valves on the flow and return
connections, refill, vent and re-pressurise the

Drain the boiler’s hydraulic circuit as detailed in
(19.2)
Remove the two screws which connect the heat
exchanger to hydraulic circuit.
(Figure 44)
