3.5.1 Incoming water pressure
The efficiency of the product depends on the in-
coming 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 reduction valve.
3.5.2 Fitting cold and hot water pipes (CW-HW),
safety valve and overflow pipe
A) Place product in the desired position. If the
product is fitted horizontally, the pipe connec-
tors must point straight up. It is recommended
that the product is secured to a wall or a suitable
surface regardless of the method chosen; use
the screw holes D, see page 7.
If the product is fitted vertically, the electric box
MUST face upwards. See pt. 3.5.7.

to the connections, tighten according to
table 3.5.3.
• For larger pipe sizes, a reducer can
be used.
C) The safety valve supplied (3) must
be fitted to the incoming CW supply pipe.
D) Any overflow pipe (5) > 1/2" inside should be
run to the overflow on the safety valve (4);
• Connect to 1/2" outside thread. Ring clamp
connector may be used (not included)
• Clear, undamaged and frost-free with
a fall to the drain.
The product is designed to be permanently con-
nected to the mains water supply. Approved pipes
