Installation
The ENWARE AQUABLEND 2500 Thermostatic Mixing Valve
should be installed to conform with AS3500, Code of Practice
and legislation applicable to each state and following the details
outlined in this section.
The ENWARE AQUABLEND 2500 must be installed by a
licensed plumber, or where applicable, a licensed plumber who
has undertaken T.A.F.E. training in Thermostatic Mixing Valves.
Note:
To effectively control microbial hazards during system
design, installation, commissioning and maintenance the
requirements outlined in AS/NZS3666-2003 and local legislation
shall be adhered to.
The inlets on the valve are clearly marked. The
Hot Inlet is
indicated by a red identification ring on the inlet and the
Cold Inlet by a blue identification ring.
If the valve is not installed correctly then it will not function
correctly and may put the user in danger. It may also void the
warranty of the valve.
Prior to the installation of the valve the system must be checked
to ensure that the system operating conditions fall within the
recommended operating range of the ENWARE AQUABLEND
2500 as detailed in Reccomended Pressures & Temperastures
Pg 7. If the hot water supply temperature is greater than 85°C
the valve may be damaged. A suitable temperature limiting
valve must be fitted to the hot water supply, prior to the inlet
fittings, if the temperature of the hot water will rise above 85°C.
This temperature limiting valve must be installed as per the
manufacturers instructions. It is also important that both of the
inlet dynamic supply pressures are 500kPa or less. If either
supply pressure exceeds 500kPa then a suitable pressure
reducing valve must be fitted prior to the inlet control valve to
reduce the pressure to an acceptable limit. These pressure
reducing valves must be installed as per the manufacturer’s
instructions. In order to achieve optimum 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 AS3500, Section 1.6 If they
do exceed these limits then it will be necessary to install a water
softener or water treatment device.
