Maintenance
Doc No: OMMB00301 Revision: 1 – Nov 2019
Section 7
Maintenance
To obtain maximum service life from the valve, periodic inspection
and cleaning should be incorporated into a normal preventative
maintenance program. Properly applied and installed AMOT
thermostatic valves require minimal maintenance. Inspection at 2
year intervals is adequate to detect normal wear.
CAUTION
Before starting any maintenance, understand the intended
use of the valve as described in Section 3.
If appropriate, read and understand the requirements
associated with use of the valve within the European Union
as described in Section 4.
Most valves must be removed from the system pipework before
commencement of maintenance. Elements in the 8” B Valve may
however be removed with the valve still in the pipework.
Ensure replacement seal kits are available (Table 7) before
maintenance begins.
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.
