PUMP STATION

The following instructions describe the installation, start-
up, function and operation of the solar pump station. The
solar pump station may only be used in the collector circuit
of a solar thermal installation. The technical data specifi ed
in these instructions must be observed. Improper usage
excludes any liability claims.
The wrapping materials that form the outer shell of the
pump station are made of recyclable materials and can be
disposed of with recyclable materials.
The solar station is a premounted valves and fi ttings group
checked for leakage used to circulate the solar fl uid in the
solar circuit.

SAFETY INSTRUCTIONS

The installation and start-up of the solar station as well as
the connection of electrical components require technical
knowledge commensurate with a recognized vocational
qualifi cation such as a fi tter for plumbing, heating and air
conditioning technology, or a profession requiring a com-
parable level of knowledge [specialist]. The following must
be observed during installation and start-up:
• Relevant local and national codes
• Accident prevention regulations of the professional
association
• Instructions and safety instructions mentioned in this
manual
The solar ball valves (a and
b) are equipped with spring-
charged check valves to prevent
gravity circulation.
