Maintenance and Servicing
The ENWARE AQUABLEND 2500 Thermostatic Mixing Valve 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.
Annual Maintenance Procedure
Every 12 months the ENWARE AQUABLEND 2500 should be
serviced and cleaned. The external surface of the valve should be
given a light wipedown. The valve & surrounding area should be
inspected for leaks or water damage and action taken if required.
The valve is to be disassembled as detailed in Figure 4.1 ,4.2
and 4.3 below. In order to service the valve, an O-ring Kit, Part
No. ATMS301 will be required, prior to disassembling the valve.
Ensure a clean dry work area is available. Open the replacement
service kit and lay all parts out neatly. Firstly isolate the hot and
cold supplies to the mixing valve by closing the inlet ball valves.
Remove the inlet fitting top cover with a suitable spanner and
then remove the mesh strainer. The strainers should be cleaned
with a dilute water solution of suitable descaling solvent (such as
CLR), checked 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 inlet valve bodies.
The non-return cartridges can be cleaned by flushing the inlet
service fittings with clean water. This can best be done by
removing the valve from the inlet service fittings and flushing
water up the pipework through
the inlet fittings and into a
bucket or similar, ensuring
that the surrounding areas are
protected from water damage.
Remove the chrome locking
nut from the top of the mixing
valve with a large flat bladed
screwdriver. Removal of the
