Installing The Unit - ESP Varimax I ASHP Installation And Operation Manual

The installation of all un-vented water heating systems above 15 litres
(this includes 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 by an engineer who
has successfully completed a recognised course in the installation of
un-vented heating systems such as CITB. 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.
