3.5 Pipe installation
3.5.1 Incoming water pressure
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.
3.5.2 Fitting cold and hot water pipes (CW-
HW) and overflow pipes
A) Turn the mixer valve to the desired position.
• Tighten ring clamp to the cylinder (see
3.5.3)
B) CW and HW pipes of a suitable size should
be run to the mixer valve and tightened (see
3.5.3)
• For larger pipes, a connector with a 1/2”
internal thread can be used.
C) Overflow pipe (1) > 18 mm inside run to the
safety valve;
• Connected to waste 3/4” internal thread.
• Clear, undamaged and frost-free with a
fall to the drain.
3.5.3 Connection to solar heating/hot water/
HW circulation
The product can be heated with water from so-
lar collectors in accordance with the guidelines
in the ErP Directive, using a 1/2” connection (3).
OSO can supply an equipment pack designed
for alternative energy sources.
1/2” connector (3) can also be used to draw off
hot water or for HW circulation.
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 regulations must be followed.
