INTRODUCTION
This guide provides instruction for the installation operation and
maintenance of concealed dual and triple control shower valves. It is beyond
the scope of this guide to provide detailed instructions for the installation
for auxiliary products which may be attached to these valves.
These shower valves must be installed in accordance with the Water Supply (Water Fittings) Regulations 1999 and in accordance with the BuidCert TMV2 scheme.
OPERATING CONDITIONS OF USE
Before installation the operating conditions of use must be checked. The
table below contains details of the necessary conditions of operation. If your
water supply cannot meet these conditions then the valve cannot be guaranteed
to operate as a Type 2 TMV2 certified shower valve. This valve is suitable for
use in both low pressure (BS 1287) and high pressure (BS 1111) operating
conditions.
Unbalanced Water Supply
Valves must always be operated within either the range for BS 1287 OR BS
1111 as described in the table below. Valves cannot operate effectively where
a hot or cold pressure system crosses the boundaries of the two ranges. In
addition the maximum ratio of unbalanced hot and cold water pressures for the
valves to operate effectively is 5:1. Hot or cold pressure must be reduced or
boosted so as to work within the required range.
Water Pressure requirements
Minimum running water pressure : 0. 5 bar
Maximum running water pressure: 5.0 bar
Maximum static water pressure : 10 bar
Water Minimum Flow Rate
For your shower to perform well you should ensure that the pressure is as
specified and a minimum flow of 5 litres per minute is available at both hot
and cold inlets.
| Low Pressure BS1287| High Pressure BS1111

Installation
Prepare pipes in wall to connect to shower, with cold on the right.
Ensure these pipes are flushed before connecting the mixer.
A G1/2″ & two G3/4″ male fittings will be required (not supplied) to connect
the outlet pipes to the mixer.
Two 3/4″ male fittings will be required (not supplied) to connect the supply
pipes to the mixer.
Offer the mixer into the recess and mark fixing locations.
Remove the mixer, depending on the wall type, drill the holes and insert
plugs, if a solid wall.
Screw to a wooden batten if fitting into a stud wall.
Connect pipes to mixer and secure mixer into position.
Ensure the mixer is level.
Once the mixer has been fitted and secured, push the concealing plate over the
mixer body, sealant should be applied between the plate and the wall.
Next push on the flow control handle on to the top valve in the mixer, tighten
the grub screw using an allen key and insert screw cover.
Fit temperature control handle to thermostat, ensuring the stop pin inside the
handle, is located against the top of the stop ring.
To test this, once fitted ,turn the handle to cold, then back to the stop
position, press the button and continue to turn.
If the handle does not function correctly remove and re-assembel.
Maintenance
Flow control valve removal
****In the event that you should need to remove the flow control valve, first
turn off water supply.
Remove the handle, unscrew the chrome shroud.
Using a spanner remove the flow control valve.
Filter Cleaning
Over a period of time, Lime scale or debris build up may occur and could
affect the performance of the mixer.
Turn off water supply.
Cleaning of the filters could assist in returning the thermostat to its
original performance.
Remove the handle from the mixer, remove the concealing plate.
Remove the filter covers, remove the filters and non-return valves.
Run these under warm water and rub or wipe to remove build up.
Re-calibration
Your product is factory set under balanced pressures, with specific inlet
temperatures, as your site conditions may differ, the temperature stop
position may require re-setting, to achieve the 38 °C.
Turn the handle to the stop position, remove screw cover and loosen grub
screw, inside handle.
Pull the handle from the mixer. DO NOT remove the plastic stop ring.
Turn the spindle until the 38 °C is achieved, once this has been reached
,replace the handle, so that the stop pin inside sits against the stop ring.
Thermostat removal (Turn off water supply)
Over a period of time, lime scale or debris build up may occur and could
affect the performance of the thermostat.
Cleaning of the thermostat could assist in returning the thermostat to its
original performance.
Remove the handle from the mixer, remove the stop ring and unscrew the chrome
shroud.
Using a spanner remove the thermostatic cartridge.
Run this under warm water and rub or wipe to remove build up.
