Application:
Fitted in accordance with NHS and/or Local
Authority requirements, typically under
handbasins or baths, and in accordance
with our Installation & Operation Instructions,
the “Brawa-Mix 97” can be used to mix
primary hot water with cold water from the
mains or a storage tank provided that both
hot and cold water conditions are within
the limits detailed in Table 1. The mixed
water entirely engulfs the sensing element,
thereby maintaining an accurate
temperature control.
The stepless adjustment between 35 and
46° C for the mixed water is by a handwheel
which is lockable, thus preventing
unauthorised tampering. High quality
calcification, dezincification and corrosion
resistant materials are used in the
manufacture of all working components.
The hot water port closes in case of failure
of the cold water supply.
In order to protect the precision machined
internal surfaces of the “Brawa-Mix 97” we
strongly recommend the use of “Y” type line
strainers (Fig Nos. 112 00 or 112 10) in the
hot and cold water supply pipes.
