Thermostatic Shower Panels
I & M Instructions
Description
The Reliance range of shower panels with a thermostatic sequential control
are designed for use in high risk environments such as hospitals or nursing
homes to protect vulnerable people from the danger of scalding.
All of the thermostatic shower panels use the same one piece sequential
thermostatic cartridge which has been tested to the NHS D08 specification,
and approved by Buildcert under the TMV3 scheme. It is available in various
versions which encompass either top or back entry connections, and a
fixed head or a hand shower. Before installation ensure that the designation
of the valve matches the application. Flow rates, dynamic pressures, and
temperature must be within the limits stated, as valves operating outside of
these conditions of use, cannot be guaranteed to operate correctly, as a type
3 shower. The shower must be installed in accordance with the Water Supply
(Water fittings) Regulations 1999 and any relevant building regulations,
specific to the application. Isolation valves & check valves must be fitted
to the hot and cold water inlet supplies feeding the shower, it must also
be installed in an easily accessible position for commissioning and future
maintenance.
Thermostatic Shower Panels
I & M Instructions
Routine Maintenance
To comply with the current NHS guidelines the Thermostatic Shower Panels
should be tested against the original performance results 6-8 weeks after
installation. If the temperatures have remained to within +/- 2°C and the
hot and cold water supply isolation tests are operating correctly, then a six
monthly cycle of performance testing can be implemented. cr
Performance Checks
Performance checks that should be carried out at routine maintenance times
are:
1. Check the set temperature using a hand-held digital thermometer.
2. Carry out the cold and hot water supply isolation tests.
3. If there is no significant change to the set outlet temperature (2°C or less
change from the original settings) and the fail-safe shut off is functioning,
then the valve is working correctly and no further service work is required.

Maintenance
Please ensure that the pipe work is flushed

Accessing the Flow Regulator (fixed head only)
I & M Instructions
The flow regulator is located behind the locking
screw on the grid shower head.
Use a 4mm allen key to remove the locking screw
which in turn will remove the flow regulator.
Remove the screws from the head and base of
the shower panel.
Replacing the Thermostatic Cartridge
With the shower in the off position, use a suitable jewellers type screwdriver
or similar, carefully remove the indices from the centre of the shower control
to gain access to the allen screw that holds the handle onto the thermostatic
cartridge.
Using an allen key, remove the
retaining screw
Once loose, lift away the facia from the head
and base of the shower panel.

Test 2. – Repeat the test for the hot supply
Record the testing done during the commissioning and also record the
temperature of the hot and cold water supplies and the temperature of the
mixed water at the full hot setting.
Remove the screws from underneath the
soap dish, twist the soap dish anti clockwise
and remove.
In-Service Testing
The purpose of in-service tests is to regularly monitor and record the
performance of the thermostatic shower panels. Deterioration in
performance can indicate the need for service work on the valve and/or the
water supplies.
If the soap dish is required then keep it safe
until re-assembly.
Procedure
Using the same measuring equipment, or equipment to the same
specification as used in the commissioning of the valve, carry out the
following sequence:
•
Record the temperature of the hot and cold water supplies
•
Record the temperature of the mixed water outlet
•
Isolate the cold water supply to the shower panel, the flow should slow to a slight drip at most
•
Isolate the hot water supply to the shower panel, the flow should slow to a slight drip at most
•
Record the equipment, thermometer etc. used for the
measurements
Alternatively to blank the connection; take the circular cover provided and
secure it to the base of the shower panel using 3 screws.

If the mixed water temperature has changed +/- 2°C from the previous test
results then this could indicate that the tap requires servicing.

Use a level to ensure the shower panel is
straight.
Thermostatic Shower Panels
I & M Instructions
Since the installed supply conditions are likely to be different from those
applied in the laboratory tests it is appropriate, at commissioning, to carry out
some simple checks and tests on each shower panel to provide a performance
reference point for future in-service tests.
In all cases the following must be checked to ensure the correct performance
of the thermostatic shower panel:
It is recommended that the shower head is
2100mm from the floor.

Drill the holes and insert the rawl plugs.
Secure the shower panel to the wall using the
four screws provided.
Once secure to the wall replace the head facia
and tighten the screws.
Then replace the bottom facia and tighten the
screws to secure.

The designation of the thermostatic shower panel matches the intended
application
The supply pressures and temperatures are within the range of operating
pressures and temperatures for the designation of the valve
It is important to record the testing done during the commissioning and
also to record the temperature of the hot and cold water supplies and the
temperature of the mixed water at the full hot setting.
Once the correct outlet temperature has been achieved, the valves internal
mechanism should be exercised at least 3 times by alternately shutting off
the hot and cold supplies while the tap is set in the full hot position. This will
cause the piston inside the cartridge to travel its full stroke and ensure that it
is moving freely so the valve can operate correctly.
Test 1. – With the shower panel in the full hot position and both hot and cold
supplies turned fully on and at system temperatures, isolate the
cold supply to the thermostatic shower panel. The flow should reduce to a drip within a few seconds. Restore the cold supply and check that the set temperature has not altered.

Note: Changing the
maximum set temperature
will change the amount
of rotation on the handle.
Increasing the temperature
will mean extra rotation
whilst decreasing will result
in less rotation.

Commissioning
The thermostatic shower panels are supplied factory set at a maximum of
38°C +/- 2°C, to alter this temperature please adopt the following procedure:
You should now be able
to see two stainless steel
cams.
With the shower in the off
position, use a suitable
jewellers type screwdriver
or similar, carefully
remove the indices from
the centre of the shower
control to gain access
to the allen screw that
holds the handle onto the
thermostatic cartridge.
One cam (lower) will be up against the brass stop while the other, the
maximum temperature cam (upper), will be approximately in mid position.
Using an allen key,
remove the retaining
screw followed by
the handle, this will
expose the top of the
thermostatic cartridge.
