INSTALLATION
9.1.3 safety devices
The cylinder is delivered with all safety and control devices for the
operation of the unvented domestic hot water supply:
- Temperature/pressure relief valve (90 °C, 7 bar)
- Pressure limiting valve (3.5 bar) with line strainer
- Expansion relief valve (one-way valve, 6.0 bar)
- Solar circuit safety thermostat, set to 80 °C, to be connected
with the solar pump in order to isolate this heat source if there
is a malfunction in the solar control.
- Safety thermostat for electric immersion heater (set to 85 °C).
- Reheating circuit safety thermostat, set to 80 °C, to be
connected to the 2-way motorised valve in order to isolate
the primary heat source if a cylinder thermostat malfunction
occurs.
- Do not bypass the thermal cut-outs or other saftey devices in
any circumstances

8 1 Instructions for use, Installation and Servicing
manual
Make sure the cylinder is stored in an upright position in a dry
environment prior to its installation.
9.2 Installation site
Place the cylinder in a suitable location in the building, paying
attention to the following:
- The tundish discharge pipe must be installed with a minimum
slope of 1:200 and must end in a safe and visible place.
- The installation surface must be flat and capable of bearing
the weight of the entire cylinder and associated controls when
full of water.
- The installation site must not be at risk of frost. If necessary,
install a frost protection thermostat.
- The control system for the installed cylinder thermostat must
be easily accessible to the operator.
- There must be sufficient space for the assembly, check and
pressure build-up of the expansion vessel.
- There must be sufficient space for the assembly, check and
maintenance of the immersion heater.
- The floor must be even.
a Where cylinders are fitted high up in the building
there are some situations where a vacuum could be
created in the cylinder. The installer must consider
in these circumstances the necessity of fitting an
anti vacuum valve to prevent cylinder damage.
This valve allows air to enter the cylinder if the
pressure becomes too low due to draining or thermal
contraction.
9.3 Installation of discharge pipe
9.3.1 Design of discharge pipe
a Risk of burns and scalds resulting from escaping hot
water.
If there is a malfunction, hot water will discharge from
the TPRV via the tundish.
- Lay the discharge pipe so that it ends at an easily
visible point inside or outside the building where
escaping hot water does not pose a risk to persons.
