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.
Pre-Installation
 the user preference must be considered
when commissioning
particular when adjusting the temperature
and timer settings.
4.2 Siting Considerations
When choosing a suitable location for the
cylinder the following
considered:
 structural integrity
 access for
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 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
replacement/maintenance
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
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.
