INSTALLATION INSTRUCTIONS
Grand Wall Valve - 20007013230
Important
• We recommend that this product is installed by a qualified professional plumber who is certified
by NVQ (National Vocational Qualification) or SNVQ (Scottish National Vocational Qualification) Level 3.
• Please check this product upon delivery to ensure that it has not been damaged and is complete.
• Before installation, please make sure this product is the correct model and you have all the parts required for installation and use.
• If possible the valve should be supplied with hot and cold water at balanced pressure.
• It is important to flush the water system to ensure that no swarf, solder, or any other impurity or foreign body can enter the valve.
• Turn off the water supply before commencing work, this should be done at the isolating valves or inlet feeds if fitted, or otherwise
at the main stopcock.
• Please read these instructions carefully and keep them for future reference.
Conditions for the use of thermostatic mixing valve
The thermostatic valve has been designed to be compliant with the relevant UK standards applicable to this type of product governed
by TMV2 standards and WRAS. The valve is tested against BS EN 2
187 & BS EN 1111.
The valve will operate under low pressure but it is recommended that the cold water supply is at least 2 meters
above the outlet of the shower valve.
• This thermostatic valve is suitable for use with all water systems up to a maximum operating pressure of 5.0 bar, (beyond which we
recommend pressure reducing valves to be fitted.)
• The valve is provided with one outlet (on the top), which is controlled by a flow control cartridge. Commonly used for a main shower
head or a flexible shower kit.
• If installing a shower pump always install the pump before the shower valve.
The list below shows the recommended limits for correct operation;

The valve should be installed in accordance with the water bye-laws. For further details refer to the latest copy of Water Bye-laws guide
or your local water authority.
Note: Please check for any hidden pipes and cables before drilling holes in the wall.
The fitting of isolation valves is required as close as is practicable to both hot and cold water supply inlets.
1. a: Determine the final installation position and installation height.
b: Prepare the water supply pipes (hot on the left and cold on the right) at the identified height with a width of 150mm centers.
Make the ends of pipes 20-25mm out from the face of wall.
c: Make an outlet at 165mm distance above the center of two inlets.
d: Put the shower valve against the wall, mark the position of the 4 fixing holes following the plate.
e: Drill 4X8mm holes on the wall to a depth of 45mm and insert wall plugs.
f: Push the shower valve over each pipe. Slide the cover plates against the wall, join inlet elbows to hot/cold pipe from the wall.
For the outlet, follow the same method as the inlet pipes.
g: Finally mount the shower valve onto the wall by using the 4 screws.
2. Install the shower arm (see Fig 2).
3. Finally put the shower head onto the shower arm (see Fig 3).

Trouble Shooting
1. Output water temperature does not correspond with temperature set
Cause:
Thermostat has not been adjusted to the existing home water system
Remedy: Adjust the thermostat , refer to “Temperature Setting” procedure.
Cause:
Hot Water temperature too low.
Remedy: Adjuster the water heater , increase hot water temperature to 65°C
2. Crossflow, cold water being forced into hot water pipe, or vice versa, when valve is closed
Cause:
Non-return valves dirty or leaking
Remedy: Clean the non-return valves or remove if necessary
3. Very low flow or no flow
Cause:
Supply pressure inadequate
Remedy: Check hot and cold feeds . If a pump has been installed, please check to see if the pump is working.
(the valve will shut down if either the cold or hot water supply fails)
4. Water will not run hot enough when first installed
Cause:
Wrong maximum temperature setting
Remedy: Adjust the maximum temperature , refer to “Temperature Setting” procedure.
