Table 3: Mixed Water Temperature

Application

Shower

Purpose

Since the installed supply conditions may be different from those applied in the factory, it is

appropriate at commissioning to carry out some simple checks and tests of the product.

Procedure

Check that:

a. the designation of the mixing valve matches the intended application.

b. the supply pressures are balanced and within the range of operating pressures for the

designation of the valve.

c. the supply temperatures are within the range of 55 - 65 °C for the valve for the prevention

of legionella etc.

Note: the final stabilised mixed water temperature during installation should not exceed the

values in table 3. if there is residual flow during the commissioning or the annual verification

(cold water supply isolation test), it is acceptable providing the temperature of the water

seeping from the valve is no more than 2 °C above the designated maximum mixed water

outlet temperature setting of the valve. temperature readings should be taken at the normal

flow rate after allowing for the system to stabilise.

Maximum Temperature Setting

the maximum blend temperature obtainable by the user should be limited to prevent

accidental selection of a temperature that is too hot.

make sure that an adequate supply of hot water is available at the hot inlet of the mixer.

the minimum temperature of the hot water must be at least 10 °C above the desired blend.

However, during resetting, this should be close to the typical storage maximum to offset

the possibility of any blend shift due to fluctuating supply temperatures. make sure that

both inlet isolating valves are fully open. temperatures should always be measured using a

thermometer with proven accuracy.
