WARNING!
READTHIS BEFORE
INSTALLING
THE UNIT.
The installation of all un-vented water heating systems above 15
litres (this includes the ESP Hot Water ASHP’s) MUST
comply with local area Building Regulations. It is a legal
requirement that the local Building Control Officer be notified
of any proposed installation.
UK regulations require an appropriately sized expansion vessel
(internal or external) to be incorporated, safety devices to prevent
the stored water exceeding 100°C, and pipe work to convey
discharged hot water safely away from the safety devices.
Furthermore, the installation must be carried out in
accordance with this manual and by an engineer who has
successfully completed a recognised course in the
installation of un-vented heating systems such as CITB. The
guidance contained in the Good Practice Guide should be
followed. Failure to fit the unit correctly and in accordance
with regulations may affect its safety, efficiency and WILL
invalidate any guarantee.
THE UNIT MUST BE INSTALLED, COMMISSIONED AND
MAINTAINED BY A COMPETENT INSTALLER IN ACCORDANCE
WITH BUILDING REGULATION G3 (ENGLAND AND WALES),
TECHNICAL STANDARD P3 (SCOTLAND) OR BUILDING
REGULATION P5 (NORTHERN IRELAND) AND THE WATER FITTING
REGULATIONS (ENGLAND AND WALES) OR WATER BYELAWS
(SCOTLAND). FOLLOWING INSTALLATION AND COMMISSIONING,
THE OPERATION OF THE UNIT SHOULD BE EXPLAINED TO THE
USER AND THESE INSTRUCTIONS LEFT WITH THEM FOR FUTURE
REFERENCE.
