Solar working station operation manual SR881

during installation and commissioning:
The relevant regional and national regulations.
The technical and safety instructions of these instructions.
Warning: risk of scalding
There is danger of steam emission with safety valves. Therefore a discharge pipe must be
connected to the safety assembly.
Attention: damage of solar pump station
The group of fittings must be installed with sufficient spacing to the collectors because
temperatures in the vicinity of the collectors can be very high. An intermediate vessel
may be necessary for installation in the attic.
It is imperative that you make sure the PTFE sealing elements of the solar pump station
do not come into contact with substances containing mineral oil. Mineral oil products
cause lasting damage to the material, whereby its sealant properties are lost.
If necessary, ask the manufacturer whether the solar fluid, fats or installation aids
contain mineral oils.
We don’t assume liability nor provide warranty for damage to solar station resulting
from sealants damaged in this way.
