3.3 Installing pressure station
• Remove outside cover (1).
• Install the RDS1 pressure station close to the hot water storage tank.
• Connect feed and return line from the solar panels to connections (4) and (5) on the RDS1 pressure station in accordance
with the system plan (see chapter 3.1).
• Connect diaphragm expansion vessel (MAG) to the connection (7) on the RDS1 pressure station.
CAUTION!
If the circulation in the solar panels comes to a standstill, steam may be formed and may damage the
diaphragm expansion vessel (MAG).
• Always install the RDS1 pressure station and the diaphragm expansion vessel (MAG) lower than the solar
panels.
CAUTION!
Danger of scalding if incorrect connection pipes are used.
• Use only connection pipes made of pressure-resistant metal (Cu Ø 22 mm recommended) between the
solar panels and the hot water storage tank. Plastic pipes must not be used.
