CALEFFI 521312TM, Installation, Commissioning And Servicing Instructions

Page: 6 / 20

Installation
The Caleffi 5213TM series must be installed by a licensed plumber or, where applicable, a
licenced plumber who has undertaken T.A.F.E. training in Thermostatic Mixing Valves.
The installer has a duty of care to ensure that all aspects of the installation comply with AS/NZS
3500 current regulations and legislation.
The Caleffi 5213TM series should be installed using the appropriate Standard, Code of Practice
and legislation applicable to each state and following the details in this manual.
Prior to the installation of the Caleffi 5213TM series valve the system must be checked to ensure
that the
system operating conditions fall whithin the recommended operating range of the
valve, i.e. verify supply temperatures, supply pressures, risk assessments, etc.
The supply system into which the Caleffi 5213TM series is to be installed must be thoroughly
flushed and cleaned to remove any debris which may accumulate during the installation.
Failure to remove any debris will affect the performance and the manufacturer’s warranty on the
product.
In areas that are subject to high levels of aggressive water, provision must be made to treat the
water prior to it entering the valve.
The valve can be installed in any position, whether vertical or horizontal. It is essential that the
access to the valve is not obstructed for future maintenance that may be required to the valve
or associated fittings.
It is essential that when the installation is designed and/or installed, all current legislation is
noted, e.g. the maximum distance from the outlet of the valve to any terminal fitting. We
recommend that the Caleffi 5213TM series valve is installed as close as practically possible to
the outlet which it is serving.
The connecting hot and cold water supplies must be connected to the valve strictly in
accordance with the indications on the body of the valve.
The inlets of the valves are clearly marked with the letters H (hot) and C (cold).
The outlet is marked with the word MIX.
Where one or both the incoming supply pressures are excessive, a Caleffi pressure reducing
valve should be fitted to reduce the pressure(s) to within the limits as quoted previously.
Any thermostatic mixing valve must be installed with isolating valves, line strainers and check
valves at both the inlets. Isolating valves are required so that the water supply to the valve can
be isolated in the event that servicing is required. Strainers are required to prevent debris from
entering the valve. Check valves are required to both hot and cold inlets to prevent cross-
connection.
The Caleffi 5213TM series is supplied complete with the line strainers and the check valves at
the hot and cold inlets.
Isolating valves at the inlets must be fitted in conjunction with the Caleffi 5213TM series.
To ensure that the performance of the Caleffi 5213TM series valve is maintained (in the event
of cold water failure), the temperature of the hot water supply at the point of entry to the valve
must be a minimum of 10°C higher than the set mixed water discharge temperature.
The pipework to and from the valve must not be used to support the weight of the valve.
If the valve is not installed correctly then it will not function correctly and may put the user in
danger.
