DANGER!
Leaking gas in the immediate proximity of electrical components can cause an explosion.
•
The Control and pump unit for solar systems EKSR3PA + EKSRDS1A and electrical components should
not be installed in locations where there is a danger of flammable gas escaping.
•
Pay attention to minimum distances from walls and in shafts.
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 EKSRDS1A pump unit and the diaphragm expansion vessel (MAG) lower than the solar
panels.

CAUTION!
Danger of scalding if incorrect connection pipes are used.
• The connection pipe between the solar panel array and the hot water storage tank must be made of
pressure-resistant metal piping (recommended Cu Ø 22 mm). Using plastic piping is not allowed.
