Maintenance Procedure - Checkvalve Cartridges
Removal and Re-assembly (Refer to Figure 3 )
Hot water entering the cold supply, or vice versa, indicates that immediate
attention is necessary. This is carried out by removing and cleaning, or renewing
as necessary, the two Checkvalve cartridges.
1.
Isolate the supplies to the shower control, and open the flow control to release
pressure and to assist the draining of residual water.
2.
The Checkvalve cartridges are located behind the backplate, to remove undo
the Checkvalve cartridge head hexagon using a 24 mm A/F wrench and pull
free.
Caution!
Some water may be released at this point.
3.
The Checkvalve cartridge assembly may be cleaned by removal of the rubber
retainers and inlet strainers, and flushing through under a jet of water to remove
lodged particles. Do not descale.
4.
Lightly wipe external seals and thread with a
silicone-only based lubricant
to
assist refitting.
5.
Re-assembly into the shower control is a reversal of the above procedures.
Do
not overtighten
when re-inserting cartridges.
6.
Restore the water supplies and check for leaks.
3.
Examine accessible 'O' seals for signs of deformation or damage, and renew
cartridge if necessary.
4.

silicone-only based lubricant
to assist reassembling.
