ANNUAL MAINTENANCE PROCEDURE
The Galvin Engineering CliniMix
®
TMV should be inspected and tested annually. The valve should be given a light
wipe down of the external surface. The TMV and surrounding areas should be inspected for leaks or water
damage and appropriate action taken if required.
Ensure the cabinet is clean before starting. Firstly, isolate the hot and cold supplies to the TMV by closing the inlet
ball isolators. Remove the inlet fitting top cover with a suitable spanner and then remove the mesh strainer. Clean
with a de-scaling solvent (such as CLR), check for physical damage and then thoroughly rinsed with clean water.
The strainers can then be re-installed into the valve, and the top cover replaced and tightened to a maximum
torque of 15Nm into the hot and cold inlet service fitting.
If the TMV fails to shut down or fails to maintain its set temperature, then refer to the fault finding solutions outlined
in Section 11.0.
The valve piston o-ring and thermostatic element / piston assembly must be replaced at intervals not exceeding
5 years.
Check that the test plugs in the top of the inlet fittings are tight and that there is no evidence of water leakage. The
TMV must then be recommissioned as per Section 7.0, including temperature adjustment and the shutdown test.
INSTALLATION INSTRUCTIONS FOR THERMOSTATIC ELEMENT/PISTON ASSEMBLY
1.
Ensure the cabinet is clean before starting.
2.
Isolate the hot and cold supplies to the mixing valve by closing the inlet ball valves.
3.
Pry off the plastic cap using a small screwdriver or similar.
4.
Remove brass Top Assembly with a suitable spanner. Care must be taken to ensure that the underside of
the Top Assembly does not receive even the slightest damage.
5.
Gently remove the element/piston assembly.
6.
Lightly grease O-rings if required. (use only potable water approved silicon-based lubricating grease such
as Molykote111)
7.
Insert new element/piston assembly taking extreme caution not to damage any surface of the piston.
8.
Refit the TMV Top assembly back to the body and tighten to a maximum torque of 10Nm.
9.
The valve must then be recommissioned as per section 7.0 including temperature adjustments and shut
down test.
INSTALLATION INSTRUCTIONS FOR O-RING REPLACEMENT
1.
Ensure the cabinet is clean before starting.
Isolate the hot and cold supplies to the TMV by
closing the inlet isolator valves.
2.
Remove the plastic cap.
