Cleaning and Re-assembly of the Thermostatic Cartridge
1.
The interior surface of the Bath and Shower Mixer body must be clean before
refitting the cartridge. If scale or deposits are present, clean using a mild proprietary
inhibited scale solvent, e.g. domestic kettle descalent. After descaling, rinse
valve interior thoroughly in clean water before refitting the cartridge.
Note! The body interior must be cleaned carefully and not damaged in any way.
Do not use any abrasive material.
2.
Cartridges may only be cleaned by flushing thoroughly under a jet of water to
remove lodged particles.
Do not descale. Cartridges are not serviceable, and must not be dismantled.
If the cartridge is faulty or damaged a new one should be fitted (refer to
section: 'Spare Parts').
3.
Examine all accessible seals for signs of deformation or damage, and renew as
necessary, taking care not to damage seal grooves.
4.
Make sure that the insulation channel cap is aligned with the hot inlet, and the
face is below the surface of the cartridge sealing bore.
Note! Make sure that the orientation is correct, as illustrated below.
5.
Lightly coat all seals with a silicone-only based lubricant to assist reassembling.
6.
Identify which is the hot inlet to the body (left hand side when viewed from the
front) and align the cartridge accordingly (stamped 'H' on the cartridge lug). Carefully
push the cartridge back into the body, checking that the 2 cartridge inlet seals
and the hot insulation channel cap remain in place and locate the cartridge lugs
into the appropriate body slots.
Note! The cartridge is not reversible.
7.
Refit the cartridge spacer and temperature stop sleeve with the upstand to the
back of the product.
8.
Refit the clamp plate and idler gear bush and tighten the 4 clamp plate screws.
