. The check valves are housed inside the retaining inserts within the inlet bores. Look closely at
the rear of the mixer body.

Note: circlips hold the check valves in position. Using circlip pliers, squeeze the circlip & lift it away
from the bore.
5.
Gently pull out the check valves: inspect & clean or replace if necessary. Observe the flow direction
arrow on the body of the check valve as shown above. Refit the circlips.
6.
To refit the mixer to the wall reverse this procedure (remember to fit the sealing washers).
NOTE: Procedure is the same for the deck mount products.
1.
Demount the mixer body from the wall, as detailed in
section 15,
follow steps 1 to 4.
2.
Locate the sealing washers (with integral strainers) from inside the
mixer’s inlet bores & keep them in a safe location.
On a regular basis the anti-splash nozzle on the bath mixer
should be inspected and cleaned if necessary
In areas where lime scale build-up is prevalent this will have to
be re- moved. An inhibited proprietary scale solvent can be used
such a kettle descaling solvent but it is important to follow the
manufacturer’s guidelines. After descaling it is important to rinse
the parts thoroughly in clean water. Clean carefully and do not
use abrasive materials or scrapers.
To remove the outlet, use a 22mm spanner to unscrew it. Locate
the spanner onto the two flats on the outlet diameter and unscrew
(anti-clockwise). Remove the outlet complete with flat seal.
IMPORTANT:
Although the check valves can be replaced, they
must not be removed
completely. Do not operate the mixer without BOTH the check valves correctly fitted.
