It is important that the mixer valve is tested
regularly to prevent the risk of scalding and
guarantee user safety. This can be carried out as
follows: with the mixer blend temperature set
at 38°C isolate the cold water supply. The outlet
flow rate will reduce to a safe level.
Fitting the coverplate (built in only)
Fit the coverplate over the valve body and slide
tight to the wall.
Make sure the seal in the opening stays in place
as it slides over the valve body. A smear of liquid
soap on the seal will ease this procedure
(fig.)
.
The coverplate incorporates a silicon sponge
backing that seals against a smooth wall.
Once the plate has been fitted, the levers will
need to be fitted into the body of the mixer and
tightened

Start the water flow by rotating the flow control
Make sure that both the hot and cold water
supplies are fully open and at (or near to) their
design temperature and pressures, and are within
the requirements as stated.
Make sure the temperature control is at the
maximum temperature setting.
Allow the shower to run at the maximum
temperature setting until the water temperature
has stabilised. Rotate the temperature control
until your desired maximum showering
temperature is reached.
The mixer has a temperature stop to prevent
accidental rotation to higher temperatures. This
is adjustable to provide a maximum temperature
of 35°C – 40°C and should be checked on site to
guarantee user safety.
Temperature adjustment range
The mixed water temperature can be adjusted
from cold through to a top limit (which can
be pre-set during installation – factory set
at approximately 38°C) with full anti-scald
protection throughout the range -
