Cleaning
It is recommended 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.
• To gain access to the filters remove the unit
from the inlet fittings.
• Remove the filter housing and disassemble.
• Wash the filters thoroughly under running
water, use a suitable brush to remove all debris.
• Reassemble and fit in reverse order.
WARNING!
DO NOT use powerful abrasive or
solvent cleaning fluids when cleaning the
shower as they may damage the fittings.
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 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.
NOTE:
The NRV’s will only operate in one
direction - water should be able to flow into the
unit from the inlets, but
NOT
back out through
the inlets.
If these checks do not highlight the reason
for the temperature variation, then internal
components will require replacement - please
contact Customer Experience.
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.
