Table 2:
The “Brawa-Mix 97” is certificated for use as a “Type 3” valve on the following outlet designations only when fitted with the appropriate sized tailpipe set.

15 mm or 22 mm	22 mm only
HP-S (41 max)	HP-T44 (44 max)
HP-W (41 max)	HP-T46 (46 max) *
LP-W (41 max)	LP-S (41 max)

(41, 44 or 46 max) relates to the maximum set mixed water temperatures as defined
within HGN “SAFE” Hot Water & Surface Temperatures.
* Refer to the above HGN for guidance when using designation HP-T46.

Example of Installation
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.
