Installing the connection set and collector...
6. Insert the strain relief fitting into the
sensor well.
7. Insert the collector temperature sen-
sor as far as possible into the sensor
well and secure with strain relief fit-
ting.
Installation
!
Please note
Incorrect installation can lead to
collector damage.
Use only gunmetal or brass fit-
tings and copper pipes for the
installation.
Use hemp only in conjunction
with pressure and temperature-
resistant sealants (e.g. Viscotex
Solarpaste from Locher,
CH-9450 Altstätten, Switzer-
land).
Never step on the collectors.
Never solder near or on the col-
lector.
1. Position pipes so that complete ven-
tilation is guaranteed. Install an air
separator at an accessible point in
the pipework (see the following dia-
gram).
2. Equip systems to EN 12975 with an
expansion vessel, safety valve and
circulation pump.

8. Insert the support sleeves into the
connecting pipes of the solar circuit.
Make the connection between the
collector array and pipework of the
solar heating circuit.
9. Fit the thermal insulation and join its
cut faces with adhesive.
3. The expansion vessel must be
approved to DIN 4807 [or local regu-
lations] and must be installed with a
thermal insulating loop. The dia-
phragms and seals of the expansion
vessel and safety valve must be suit-
able for the heat transfer medium.
To calculate the pre-charge
pressure, see the "Vitosol"
service instructions.
4. When operating without a Solar-Div-
icon, only use safety valves designed
for 120 °C, a maximum pressure of 6
bar, and which carry the "S" (Solar)
designation.
5. Make all connections pressure and
temperature-resistant (observe the
maximum idle temperature of the col-
lector).
