The following steps are required: -

1) Ensure the fitting is turned off

2) The cold water isolator should be closed, this is accessed by unscrewing

the shroud (13) and pulling it back along the elbow taking care not to

scratch the chrome, the 2.5mm hexagon wrench is inserted in the

isolating plug (6) and rotate it clockwise until it locks.

3) The back cover (3) is unscrewed using a 2.5mm hexagon wrench and put

to one side.

4) The flushing screw (19) is unscrewed downwards till it is level with the

bottom of the body (do

not

5) Turn the fitting on, hot water at the inlet temperature will pass through

the unit pasteurising the waterways and flow straightener.

6) Turn the fitting off.

7) The flushing screw (19) is screwed upwards till it locks.

8) Replace the back cover (3) , reinstate the cold water and replace the

shroud (13).

The unit is now ready for use.

Commissioning

If the authority concerned already has a suitable commissioning and

maintenance program in operation then this section can be disregarded. If not

this section can be used as a guideline to introduce such a system.

The purpose of any commissioning and in service testing procedure is to set the

valve correctly and monitor any deterioration in the valves thermal performance.

remove completely) see Fig4.

Cleaning integral filters

The integral filters are fitted into the inlet elbows to the fitting. The fitting

should be removed from the bases as described in the previous section the filters

are then accessible for servicing as shown in Fig3. They are a friction fit into the

adaptors and should be care fully prizes out washed and refitted. Failure to refit

the filters may invalidate the guarantee.

Flow limiters

As supplied the fitting has flow limiters fitted to both inlets so it is suitable for

high-pressure use. For use on low pressure they may need to be removed see

table below. The procedure described above for cleaning the filters should be

followed. After removal of the filter the flow limiters are visible and should be

removed using a small pointed instrument.

Pasteurising system

In order to kill off any bio film growth this range of fittings has a built in

cleansing feature that allows the mixed water passages to be flushed with hot

water without the need to disassemble the mixer or reset the mixed water

temperature.

Owing to the high water temperatures passing through the fitting this operation

should only be performed by a competent person using the necessary safety

equipment.
