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 unit is required to give
continued performance after installation and that
it continues to provide scald prevention.
Note: a thermostatic mixing valve in need of
maintenance can be undetectable in normal use
and only becomes apparent when a disruption
occurs in the hot or cold water
supply temperatures or pressures.
It is a requirement that all TMV2 approved
valves shall be verified against the original set
temperature results
once every 12 months .
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 this work out
(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 see
the spare parts list.
WARNING!
DO NOT use ‘powerful’ abrasive or
solvent cleaning fluids when cleaning the
shower as they may damage the fittings.
Cleaning
Triton recommends that all products are cleaned
using warm, soapy water.
Do not use abrasive or aggressive chemical
cleaning products as this may affect the product
surface finish and invalidate your guarantee.
Cleaning the filters
(fig.A)
It is advised that this should be carried out by a
qualified person.
• Turn off the water supplies before starting.
• Remove the mixer from the mixer bracket.
• Remoce the retaining clips in the hot and
cold inlets.
• Remove the none return valve and filter.
• Wash the filter thoroughly under running water,
use a suitable brush to remove all debris.
• Reassemble in reverse order.
Disinfection
Where chlorine is used for the disinfection
of water systems all relevant guidelines and
approved codes of practice must be strictly
followed. Failure to comply with the relevant
guidelines and approved codes of practice may
invalidate your guarantee.
