performance from the valve it is recommended that the inlet
pressures are balanced to within 10% of each other. The water
quality conditions should be checked to ensure they do not
exceed the limits as listed in Section 1.6 of AS3500.4. If they do
exceed these limits then it will be necessary to install a water
softener or water treatment device.
NOTE: In some installations where certain types of
tapware, such as flick mixers and solenoid valves, are
used; the water pressure may be seen to spike outside that
recommended for the valve during rapid shut off conditions
with these types of devices. Even if the spike only lasts a
split second it is still considered to be outside the operating
conditions and may cause the valve to operate incorrectly.
In the event that this does occur measures must be taken
to control the spike, such as inline pressure reducing valves
directly before the valve inlets.
To ensure that the mixing valve operates correctly it is
necessary that the pipework is thoroughly flushed with
clean water before the valve is installed. This will remove
any physical contaminants from the pipework, ensuring
trouble-free operation. During the flushing procedure care
should be taken to prevent water damage occurring to the
surrounding area.
It is required by AS3500.4 Sec 3 that “Each Thermostatic
Mixing Valve shall have an isolating stop tap/valve, line
strainer and non-return valve fitted to the hot and cold water
supply lines” . The inlet fittings supplied with each TMV will
ensure this requirement is met. If the ENWARE AQUABLEND
2000 Thermostatic Mixing Valve is to be installed without the
supplied inlet control valves then it will be necessary to install
a separate isolating valve, non-return valve and strainer to
both inlets to the valve. Strainers must be fitted to prevent
any particulate contamination from entering the valve. These
strainers should be 60 Mesh stainless steel. Isolating valves
are required so that the water supply to the valve can be
