Bath (46°C fill)
* For preset outlet temperature adjustment – See page 63.
NB. If a water supply is fed by gravity then the supply
pressure should be verified to ensure the conditions of use
are appropriate for the valve. Valves operating outside of
these supply conditions cannot be guaranteed to operate
as a TMV2 or TMV3 valve.
Recommended outlet temperatures
The BuildCert TMV scheme recommends the following
set maximum mixed water outlet temperatures for use in
all premises:
44°C for bath fill but see notes below;
41°C for showers;
41°C for washbasins.
The mixed water temperatures must never exceed 46°C.
The maximum mixed water temperature can be 2°C above
the recommended maximum set outlet temperatures.
Note: 46°C is the maximum mixed water temperature
from the bath tap. The maximum temperature takes account
of the allowable temperature tolerances inherent in thermo-
static mixing valves and temperature losses in metal baths.
It is not a safe bathing temperature for adults or children.
The British Burns Association recommends 37 to 37.5°C as
a comfortable bathing temperature for children. In premises
covered by the Care Standards Act 2000, the maximum
mixed water outlet temperature is 43°C

Installation Requirements
This thermostatic mixer valve must be installed in comp-
liance 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 valve is suitable for use with the following water
supply systems:
Gas Combination Boiler (multi-point) 1.0 - 10 bar*
Unvented System (pressure balanced) 1.0 - 10 bar
Pumped System 1.0 - 10 bar
IMPORTANT: If you install this mixer with a gravity fed
system, there must be a minimum head (vertical distance)
from the underside of tlie cold water storage tank to the
showerhead position of at least 5 metre.
Before connecting the mixer, water should be flushed
through the system to remove all debris that might otherwise
damage the valve.
* If pressure is in excess of 3.5 bar, a pressure-reducing
valve should be fitted.
