Maintenance - Triton DENE CONCENTRIC Mini Mixer Installation And Operating Instructions Manual

MAINTENANCE

The following maintenance procedure must
be carried out for commercial and health care
premises, but is not necessarily required for
domestic installations.
Maintenance of the mixer shower is required to
give continued performance after installation and
that it continues to provide scald prevention.
NOTE: A thermostatic mixer shower in need of
maintenance can be undetectable in normal
use and only becomes apparent when a dis-
ruption occurs in the hot or cold water supply
temperatures or pressures.
The frequency of routine maintenance of the
internal of the shower will depend mainly on
the water supply condition. Experience of local
conditions will dictate the intervals for inspection
and in-service testing. Guidance has been
given below which can be adjusted for local
requirements.
a) Initially check the filters for debris once every
three months and clean if necessary.
b) Perform a thermal shut off test
every three months, and check the
maximum temperature setting. See the
'Commissioning' section for the details of
this test and readjustment of the maximum
temperature setting if required.
c) If the maximum water temperature varies
by more than 2°C from the commissioned
setting then carry out the following checks
• Check the isolating valves are fully open.
• Check the internal surface for scaling.
If the body requires descaling then it should be
removed from the pipework to carry out this
work. All rubber parts must be removed before
descaling.
• Check the function of the non-return valves
The non-return valves (NRVs) prevent
cross-flow between hot and cold supplies
under unequal pressure conditions. They are
designed for long life with no maintenance.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement; please
contact Triton's Customer Expericence team.
