maintenance and servicing - eTMV
The eTMV is a compact Thermostatic Mixing Valve that uses modern self-controlling
multiprocessor technology to monitor and control the temperature and flow, by means of
ceramic discs and electromechanical drives.
eTMV does not have a thermostatic wax element or dynamic O-rings that are typically
used in traditional thermostatic mixing valves. Instead, ceramic discs are controlled by
electromechanical drives, and eTMV has no parts to service or replace during regular
servicing.
The eTMV is constantly monitored for real-time performance by the Enware Smartflow TMV
monitoring system.
The eTMV will only require minimal preventative maintenance work to ensure it operates at
its optimum level of performance. The valve should be commissioned, and serviced annually,
unless the installed conditions dictate more frequent servicing is necessary.
Every 12 months eTMV should be inspected and tested. The valve and surrounding area
should be inspected for leaks or water damage and action taken if required. Ensure a clean
dry work area is available.
Servicing of eTMV is in line with AS4032.3.
Cleaning the Strainers
Firstly isolate the hot and cold supplies
to the mixing valve by closing the inlet
isolation valves. With a suitable spanner
remove strainer cap on the inlet fitting then
remove mesh strainer.
Clean strainers with a suitable descaling
solvent (such as CLR) diluted with water.
Check for physical damage and thoroughly
rinse with clean water. Strainers can then
be re-installed into the ball valve and
strainer cap replaced and tightened to a
maximum torque of 15Nm into the inlet ball
valve bodies.
Non-Return Valve Operation
To check Non-Return Valve on the HOT
inlet side, carry out the following steps:
