Maintenance
We advise that the below is carried out annually as failure to do so may result in
invalidation of warranty.
Isolating the thermostatic valve
IMPORTANT:
Please see the below procedure for isolating the thermostatic valve.
1. Isolate the incoming hot and cold water to the valve.
2. Turn shower valve on (left handle) to check isolation, please ensure that your body/
hands are not under the flow of water as there is a potential for delivery of hot water.
3. Remove temperature control handle and temperature stop ring (essential).
4. With shower in the on position, replace temperature handle on thermostatic Valve
(ensure temp stop has been removed).
5. Turn temp handle fully anti clockwise until stop point is reached and can be turned no
further , please ensure that your body/hands are not under the flow of water as there is
potential for delivery of hot water if isolation has been unsuccessful.
6. Turn temperature handle fully clockwise until resistance is felt.
7. If there is no flow of water coming from the outlet during both points 5 and 6 isolation
has been successful, you may now remove and maintain the cartridge.
8. If at any of the above point’s water continues to flow please isolate at an alternative
point within the system for both hot and cold and repeat points 2-8.
Filters
This thermostatic valve is fitted with a double filtering facility.
Filters are fitted on the water inlets and on the thermostatic cartridge.
Depending on the water quality, filters may become dirty,
causing reduced flow and inefficient working of the valve.
Inlet filters
Check water has been isolated. Undo both locking nuts at the back of the valve and
remove from the wall. Pull out the filter/washer, rinse in water to remove the dirt, and
then soak them in vinegar or descaling agent.
Thermostatic cartridge
To clean the filters, you must first remove the cartridge from the housing.
Removing the Cartridge:
1. Check water has been isolated.
2. Remove the stop ring
3. Using a suitable spanner remove the thermostatic cartridge.
4. Clean filters by rinsing them under running water to remove any debris.
5. If there is limescale deposits then it is recommended to immerse the cartridge for a
few minutes in 50% white v 50% hot water, brush the filters gently and then rinse
under running water to clean all particles. If this is not effective, a replacement cartridge
should be fitted.

7. Reassemble the cartridge into the body, then place the plastic stop ring onto the
cartridge with the step at the 12 o’clock position.
8. Turn on the water supply.
9. Check the water temperature to ensure correct commissioning.
See page 13 of this guide for commissioning.
