pushing the black outlet boss back into the heat
exchanger and refitting a new bracket.
If the fault occurs again without the hose being damaged
or the handset blocked, contact our Service Department.

whilst showering,
cyoling hot/ cold.
A. Thermal cut-out is operating,
normally making a 'click' as it
does so.
A. Increase the flow by turning the water control knob
anti-clockwise. Clean the handset and spray plate.
B. Input pressure is below the
minimum required (see
section
2.1
).
Flow is unstable.
B. Ensure that your stop cock and servicing valve are
fully open. If they are, ask your installer or the local water
company to check that the running pressure is above the
minimum required (See
para. 2.1
)
6. Cold Flow. 'Power
On' indicator not lit.
Isolating switch 'On'
but its neon not lit.
A. Cartridge fuse or miniature
circuit breaker (mcb) has
operated in your fusebox (or
consumer unit) or switch fuse.
A. Switch off power and isolating switch. Renew fuse or
reset mcb. If they operate a second time, contact a
qualified electrician.
B. Residual current device (rcd)
(earth leakage circuit breaker)
has operated.
B. 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 shower
feed cable is connected to the 'protected' neutral bar of
the unit.

Where the fault cannot be corrected by either yourself or your installer, contact our service department (address and
phone number on front cover), who will try to help over the phone. If necessary, they can arrange a visit by one of our
service engineers. We find that the vast majority of problems can be solved by reference to these fitting instructions or
by discussion over the phone. In the event that our engineer is called and finds that the fault is caused by faulty
installation or usage, or lack of reasonable maintenance, a call-out charge will be made.
