4 Pre-Installation Advice
Please read the following section carefully
before commencing installation. If in any doubt,
please call the appropriate help desk.
Disregarding the instructions given in this
manual in its entirety and any relevant
regulations, standards and codes of practice will
void the guarantee of this product.
Handling – depending on the size of the
unit and access to its installation location,
consideration must be given to the handling
of the unit. Please note that handling,
installation and use of this product is
subject to the Health and Safety at Work
Act. If the unit is not installed immediately,
it should remain in its protective packaging
with all pipe protectors/end caps applied to
prevent damage and dirt deposit inside the
cylinder and the coils.
Pipe Work – the pipe runs should be
executed as short as possible, unused pipe
work should be removed and all remaining
pipe work should be lagged in accordance
with regulatory requirements to prevent
heat loss and the formation of condensation.
Taps and Fittings – all taps and fittings
incorporated in the unvented system should
have a rated operating pressure of 0.6 MPa
(6 bar) or above.
4.1 Risk Assessment
The compilation of a risk assessment is strongly
recommended before installing the product. The
following areas require particular consideration
in addition to the information required by the
Health and Safety at Work Act.
scalding: where appropriate or required by
law a thermostatic mixing valve is to be
fitted to the hot water outlet of the cylinder
(see also water borne organisms).
explosion: the unit is fully equipped with all
relevant safety equipment to comply with
current regulations. The correct design and
function has been verified by independent
third party testing. The correct application
thereof is the responsibility of the
competent installer.
water borne organisms (i.e. Legionella): if
applicable a risk assessment should be
carried out following the recommendations
outlined in the Approved Code of Practice
L8.
the user preference must be considered
when commissioning the system, in
particular when adjusting the temperature
and timer settings.
4.2 Siting Considerations
When choosing a suitable location for the
cylinder the following aspects should be
considered:
structural integrity
access for installation, operation,
maintenance and replacement
routing of discharge pipe work
access to water mains supply, hot and cold
water distribution pipe work
access to suitable electricity supply
location in relation to remaining system
components such as auxiliary and solar
heating system
frost protection
The heat pump cylinder range is designed to be
floor standing, vertically mounted, indoors and
in a frost free environment. The cylinder may
be located on any flat and level surface,
provided it is sufficiently robust to support the
weight of the cylinder when full of water (please
see technical data) and suitably accessible for
replacement/maintenance without specialist
tools or lifting equipment as this will void the
warranty conditions.
The position and orientation of the cylinder
should be such that easy access is provided for
servicing the controls. A minimum distance of
400mm in front of the immersion is
recommended, to allow the replacement of the
immersion heater should the need arise. When
installing the cylinder all labels should be clearly
visible and ensure that no pipework hinders any
work to be carried out on the various cylinder
components.
Particular care must be taken when placing the
cylinder in a garage or outbuilding. All exposed
pipe work must be correctly insulated to avoid
frost damage.
