Fault Diagnosis – Installer Maintenance
The Thermostatic Power Shower is one part of an entire plumbing
system. The fitting of a pump places additional requirements on the
plumbing system. Some systems may require plumbing modifications
to allow them to cope with higher flow rates.
Providing the Thermostatic Power Shower has been correctly installed
and is operated as advised, difficulties should not arise. Fault diagnosis
and maintenance must be carried out by a competent person for whom
the fault diagnosis table is provided.
In the event of any of the following tests failing, re-check as appropriate before
contacting the Customer Service Department (Refer to
Back Cover
).
Shower runs for a
short time (30-60
seconds) then flow
reduces, splutters or
stops. Aggravated
when other hot taps
are in use. Less
evident on full cold.
Air is being sucked down
the vent pipe, as the hot
take off to the shower is
too high up the pipe.
