DANGER
Danger to life
During operation the ball valves of the solar station
must be in open position.
The collector must be protected from excess pres-
sure by a safety valve and a diaphragm expansion
tank. (see also operating instructions "Con-
struction, initial operation and maintenance of
thermal solar plants" at www.oventrop.com).
Initial operation solar station
WARNING
– Never fill up installation with solar liquid when
temperatures are high Cover collectors during
sunshine and let them cool down
– Risk of scalding with high temperatures in the
solar circuit (collectors > 60°C) Steam may
form in the collectors during intense solar ra-
diation.
– Check correct pressure at the inlet of the ex-
pansion tank.
Flushing of the solar circuit
– Flush solar circuit with heat transfer liquid.
– Dry running of the filling pump is inadmissible.
– Use filter (integrated in most mobile filling stations)
Mobile filling station
A mobile filling station (item no. 136 42 40) allows a
quick and clean flushing and filling of thermal solar
plants – a safe deaeration is thus guaranteed.
The compact unit consisting of pump, tank for solar
liquid, filter and hose bracket is mounted on a rugged
chart for an easy transport.
