"click" as it does so
below 1.0 bar
(14.5psi); flow is
not stable

off
REMEDY
Increase the flow by turning the stop valve
Ensure that the electrical supply to the Multipoint
Instantaneous is switched on and the neon is lit
Reduce the flow by adjusting the water control
isolating valve
Check for open circuit
Check water pressure/flow
Ensure that your stop cock and servicing
valve are opened fully
Switch off Multipoint Instantaneous and isolating switch.
Renew fuse, reset the mcb. If they operate
a second time, contact a qualified electrician
Follow the same procedure as above. If this
has happened with a "split load" consumer
unit on initial installation, check that the
neutral core of the Multipoint Instantaneous feed cable
is connected to the "protected" neutral bar of the unit
1. Switch off immediately at isolating switch
2. Turn water off at the servicing valve (if fitted)
or stop valve
3. Contact Heatrae Sadia Service Department
