Section 7 Maintenance
To obtain maximum service life from the valve, periodic inspection and
cleaning should be incorporated into a normal preventative maintenance
program.
Before starting any maintenance understand the intended use of the
valve as described in Section 3.
If appropriate read and understand the legal requirements associated
with the valve within the European Union as described in Section 3.
WARNING
Ensure that all pressure is relieved from within the valve and
ancillary equipment and drain system (or isolate valve) before
commencing any maintenance work.
7.1 Dismantling the valve
Properly applied and installed AMOT thermostatic valves require minimal
maintenance. Inspection at 2 or 3 year intervals is adequate to detect
normal wear. In the 8B valve the element assembly may be removed
without removing the valve from the connecting piping. All other sizes
must be removed from the piping. Some sizes have two or more
independent temperature elements.
