Maintenance Procedure - Inlet Strainers
Blockage of the inlet strainer screens can lead to poor flow performance and reduced
temperature control. It is essential that the inlet strainer screens are cleaned or, if
necessary, renewed as part of the six-monthly maintenance operations.
A Strainer pack is available for all Exact-3 and 215 series models, containing 2
strainer screens and all the seals (plus lubricant) and nylon washers that may need
to be renewed during Strainer inspection (see
component matrix
).
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 strainer screens are located at the inlet of each Checkvalve cartridge.
To access the inlet strainer screens:
Exact-3:
remove the
Checkvalve cartridges
.
Exact-3 z:
remove the shower control body from its pipework connections.
3.
The strainer screens are dished outwards and are a push-fit into the housing.
Remove carefully.
4.
The strainer screens may be cleaned under a jet of water, or renewed.
5.
Re-assembly into the shower control is a reversal of the previous procedures.
Do not overtighten
when re-inserting cartridges.
6.
Restore the water supplies, and check for leaks.
Maintenance Procedure - Elbow/Body Seals
Both models have inlet and/or elbow adaptor seals and elbow seals, which are
static and should rarely require renewal. These seals are included in the service
pack and may be accessed if necessary:
1.
Isolate the supplies to the shower control, and open an outlet fitting to release
pressure and to assist the draining of residual water.
2.
Release inlet and outlet connections.
3.
Remove elbows by loosening each elbow grub screw using 2.5 mm A/F
hexagonal wrench.
4.
Remove the adaptors using a 12 mm hexagonal wrench.
5.
Lightly coat seals with a
silicone-only based lubricant
to assist re-assembly.
6.
When re-inserting adaptors,
do not overtighten
.
7.
Refit and remake pipework connections, restore hot and cold supplies and check
for any leaks.
