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)
and overflow pipes
A) Turn the mixer valve to the desired position.
• Tighten ring clamp onto the cylinder (see 3.5.4)
B) CW and HW pipes of a suitable size should be
run to the mixer valve and tightened (see 3.5.4)
• For larger pipes, a connector with a 1/2" inter-
nal thread can be used.
C) Overflow pipe (1) > 18 mm inside run to the
safety valve;
• Connected to waste 3/4" internal thread.
• Permanently open, visually accessible 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 solar
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.
3/4" connection (4) is used for the anode.
