1. Safety instructions

1.1 Regulations/ Guidelines

Read through these instructions carefully before installation. The complete station must be installed and initially started up by an approved,
qualified firm. Familiarise yourself with all the parts and their handling before starting the work. Please follow these safety instructions
precisely to prevent risks and harm to people and material property. Note and observe the accident prevention regulations/health & safety
regulations, the environmental regulations and the statutory regulations for assembly, installation and operation. Furthermore, the relevant
safety provisions of the DIN, EN, DVGW, VDI and VDE (incl. lightning protection) as well as all relevant country-specific standards, laws and
guidelines.
Electrical connection:
Electrical connection work may only be carried out by qualified electricians. The VDE guidelines and regulations of the electrical utility
company responsible must all be complied with.

1.2 Intended use

The stations described are to be operated for primary side operation of the solar substation with suitable or approved solar liquid. Ensure the
liquid has an adequate antifreeze content.
Media temperature > 60 °C (Risk of scalding)
Setpoint and fi lling pressure < pickup pressure of the safety fi tting
The shut-off fi ttings may not be connected as otherwise the safety fi ttings lose their eff ect.
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 start-up

Before starting the system for the fi rst time, check for leaks, correct hydraulic connection and fl ush carefully. The initial start-up must be
carried out by a trained, qualifi ed person and must be recorded in writing. In addition, the set values must also be recorded in writing. The
technical documentation must be kept with the equipment.
