3.5.5 Torque settings
3.5 Pipe installation
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 to the cylinder (see
3.5.3)
B) CW/HW pipes of suitable size run to mixer
valve and tightened (see 3.5.3)
• With larger pipes, a reducer with 1/2"
internal thread may be used.
C) Overflow pipe (1) in a suitable dimension
can be run to safety valve
• Connects to the 1/2” / ø15 mm outlet (2)
on the safety valve
• Must be fitted uninterruptable, undamaged
and frost-free with a fall to the drain.
3.5.3 Connection to coil
The product is equipped with pipe elbow con-
nectors to the coil (4). The elbows has a 3/4”
ring clamp connection for flow/return pipes.
Fit pipes of suitable material/quality and tight-
en the ring clamps.
3.5.4 Connection to solar heating/hot water/
HW circulation/sensor tube
SC comes with a sensor tube (ø10 mm internal)
factory-fitted (3). This is intended for a tem-
perature sensor to control any external heat
source connected to the coil. The sensor slot
can be removed if the connector is to be used
for a different function.
The product is designed to be permanently con-
nected to the mains water supply. Approved pipes
of the correct size should be used for installation.
The relevant standards and regulations must be
followed.
The product can be heated with water from
solar collectors. OSO can supply a kit to utilise
alternative energy sources, which prioritises
solar heat over the electric heating element.
The product is equipped with a factory fitted
P&T 10 bar/90-95°C pressure and temperature
valve (5).
