Method for demounting mixer:

1. Observe disassembling sequence, as detailed in section 14, steps 1 & 2.

2. Remove the overhead shower assembly, if tted (A7543AA only).

3. Slide back both escutcheons away from the wall towards the mixer body. Undo the two coupling nuts

located at the rear of the mixer (see g above). Take care not to lose the two sealing /strainer washers.

4. Lift the mixer body o󰀨 from the wall mount brackets, by gently pulling away as shown.

5. The mixer body can be further dismantled for cleaning protocols. Do not leave the wall mount

brackets uncovered for long periods, protect from environmental contamination.

6. To ret the mixer body; reverse this procedure. Tighten the nuts at the rear of the mixer securely.

Disinfection method

Disinfection by full immersion in an appropriate bactericidal solution is recommended for this assembly.

Prior to immersion, the mixer body should be clean and dismantled to a level that prevents air locking.

The level of dismantling should be established as a result of practice and will be largely dependent upon

the water quality and service life. As a minimum we recommend removal both handles, thermostatic

cartridge & ow-control (or diverter) cartridge. Cleaning the cartridge strainer screens is important. All

components can be immersed together unassembled.

Disinfected mixers should be promptly replaced or stored using an appropriate method until required.

Disinfection frequency

The frequency of such disinfection actions will be derived from regular sampling carried out under the

regime of the Responsible Person (Water). We would not expect to need greater than 6 monthly fre-

quencies, hopefully considerably less.

The need for excessive use of this procedure would be indicative of the need for some root cause analy-

sis as there could be some system or behavioural problems that need addressing.
