INSTALLATION
The Enware Aquablend 1500 Thermostatic Mixing Valve should
be installed using the appropriate Standard, Code and legislation
applicable to each state and following the details outlined in this
section.
The Enware Aquablend 1500 must be installed by a licensed
plumber, or where applicable, a licensed plumber who has
undertaken TAFE training in Thermostatic Mixing Valves.
NOTE: To effectively control microbial hazards
during system design, installation, commissioning and
maintenance, the requirements outlined in AS/NZS3666 and
local legislation shall be adhered to.
Inlets and outlet connections of the valve are clearly marked. The
letters H and C cast into the valve body indicates the Hot and
Cold Inlet respectively. An arrow cast into the body of the valve
identifies the valve outlet direction.
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 Aquablend 1500
Thermostatic Mixing Valve as detailed on page 7 - recommended
temperatures and pressures.
If the hot water supply temperature is greater than 90°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 90°C.
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. For optimum performance from the valve it is
recommended that the inlet pressures are balanced to within
10% of each other.
