1. Safety notes

1.2 Intended use

The described station is intended for primary operation of the solar substation with propylene glycol - water mix-
tures. Use of other media is not allowed.
Media temperature > 60 °C(Risk of scalding)
Setpoint and filling pressure < pickup pressure of the safety fitting
All shut-off fittings may be closed in the service case only and only if the collectors are covered as otherwise the
safety fittings lose their effect.
Caution:
Do not make any changes to electrical components, the design or the hydraulic components! Otherwise you will
impair the safe function of the system.

1.3 Initial commissioning

Before the initial commissioning, the system must be checked for any leakage as well as to make sure the hydrau-
lic linkage is correct and that the electrical connection work has been carried out with care and correctly. The sys-
tem must also be carefully flushed in accordance with DIN 4753. The initial commissioning must be carried out by
a trained specialist and a written record of it must be drawn up. In addition to this, the settings must also recorded
in writing. The technical documentation must remain with equipment..

1.4 Working on the system

The system must be disconnected from the power supply and checked to ensure it is safely isolated from the
power supply (e.g. at the separate fuse or a master switch).
Secure the system against being switched back on again.
IMPORTANT: Risk of scalding:
Media temperature > 60°C

1.5 Liability

We reserve all copyrights to this document. These installation and operating instructions must be handed over
to the customer. The skilled trades carrying out the work (e.g. fitter) must explain to the customer how the equip-
ment works and how to operate it in a way they can understand.
