• Remove all packaging and check the contents for damage before starting installation.

• Before starting any installation please consider the following: before drilling into walls, check

that there are no hidden electrical wires, cables or water supply pipes.This can be checked

with the aid of an electronic detector.

• If power tools are used do not forget to: - Wear eye protection

- Unplug equipment after use

• Fitting isolating valves to the inlet feeds is required for ease of maintenance.

General Information

Operating pressure range: Minimum 0.2 bar, Maximum 5.0 bar.

Maximum static pressure: 10.0 bar.

This product has been tested to the TMV3 scheme for use in Healthcare and Commercial

situations and performs to the requirements of NHS Specication D08. It also satises the

requirements of the water supply (water ttings) regulations 1999 and current bylaws.

BS 8558 recommends hot water should be stored and distributed at a temperature of not less

that 60°C which will help minimise the build-up of lime scale in hard water areas.

If the tting is installed at low pressure (tank fed), then the minimum distance from the outlet

to the underside of the cold tank should be at least 2 metres to ensure adequate performance.

Note: Nominally equal (balanced) inlet supply pressures are recommended for optimum

performance with mixer taps.

This mixer tap should be installed in compliance with the Water Regulations.

If in doubt, contact a registered plumber or your Local Water Authority or the Secretary of The

Institute of Plumbing, address as follows;-

Product Benets

On / Off and Temperature Control

Turn the lever anti - clockwise to turn on the

ow of water.

The water temperature will increase the

further the lever is turned.

To decrease the temperature of water turn

the lever back clockwise.

Thermal Disinfection Flushing

In order to control the build up of bacteria

and to assist against legionella, this TMV has

a built in cleansing feature that allows the

mixed water passages to be ushed with

hot water without the need to disassemble

the mixer valve or reset the mixed water

temperature.

Easy Clean Filters

This TMV has easy clean lters which once

removed isolate the water supply to the

mixer body.

TMV3 Approved

This TMV has been tested to the TMV3

scheme for use in Healthcare and

Commercial situations and performs to the

requirements of NHS Specication D08.

Removable Spout

The mixer tap has a removable spout to

assist with your infection control regime.

Cool Touch Body

The mixer body and hot inlet will only ever

reach the mixer water outlet temperature to

prevent scalding.

Installation Requirements

This mixer tap must be installed in

compliance with current water regulations.

If you have any doubts about the water

regulation requirements contact your local

water services provider or use the services

of a professional plumber.

This mixer tap is suitable for use with the

following water supply systems:

• Gravity Fed Hot and Cold

(pressure balanced)

• Gravity Fed Hot and Mains Cold (differential

pressure - see Specication section on page

• Instantaneous water heater

(combination boiler)

• Unvented System

• Pumped System

Gravity Fed Hot and Cold Gravity Fed Hot and Mains Cold

cold mains supply cold mains supply

Important: If you install this mixer tap

with a gravity fed system, there must be

a minimum head (vertical distance) from the

underside of the cold water storage tank to

the outlet of at least 2 metres .

Note: Pumped system (with Essex ange)

If you install this mixer valve to a pumped

gravity fed system where the minimum head

(vertical distance) from the underside of the

cold water storage tank to the top of the

hot water cylinder is less than 1 metre we

recommend an Essex ange is used as shown.

Flushing Pipe-work

Important: Before connecting the mixer

tap (see ‘Installation’ on pages 13-14),

the supply pipe-work must be ushed to

clear debris before connecting the mixer tap.

Debris will reduce the performance and life

of the mixer.

For backow protection in premises or

installations up to, and including Fluid

Category 5.

The vertical distance of the outlet above the

spill-over level shall be not less than 20mm
