3.5 Pipe installation
The product is designed to be permanently
connected to the mains water supply. Ap-
proved pipes of the correct size should be used
for installation. The relevant standards and reg-
ulations must be followed.
The efficiency of the product depends on
the incoming cold water pressure. The water
pressure should be min. 2 bar and max. 6 bar
throughout the day. Excessive water pressure
can be adjusted by installing a pressure reduc-
tion valve.
Pipes of suitable size and quality should be run
to the connections on the product and fixed
with a suitable sealant.
A safety valve (see pt. 2.3) suitable for the in-
stalled effect in accordance with current local
regulations shall be fitted in the heating circuit
(not supplied).
