1. Route pipes so that they can be
completely vented. Install at least
one air vent valve with shut-off
facility at the highest point of the
system. Install an air separator at
an accessible point in the pipework
(see illustration on page 52).
2. Equip the system to EN 12975 with
expansion vessel, safety valve and
circulation pump.

Commissioning and adjustment

For commissioning of the solar heating system, see "Vitosol" service
instructions.
3. The expansion vessel must be
approved to DIN 4807 and must be
arranged with a heat insulating
loop. The diaphragms and seals of
the expansion vessel and the
safety valve must be suitable for
the process medium.
For the calculation of the
inlet pressure, see the
"Vitosol" service instruc-
tions.
4. When operating without Solar-Divi-
con, only use safety valves
designed for 120 °C and a maxi-
mum of 6 bar which carry the "S"
(Solar) designation.
5. Make connections pressure and
temperature-resistant (observe the
max. idle temperature of the collec-
tor).
