Mounting And Commissioning (Fig. B); End Of Operation; Care And Maintenance - Rothenberger ROSOLAR PUMP Instructions D'utilisation

3.3 Mounting and commissioning
 Connect filling hose (1) to pump outlet (4) (fig-B1).
 Connect return hose (2) to tank (fig-B2).
 Connect filling hose (1) and return hose (2) to the fill/vent valves and open valves (fig-B3).
 Fill tank (3) and open ball valve (6) (fig-B4).
 Insert cable of pump motor into socket (fig-B5).
 Switch on pump (fig-B6).
 Open tank lid (7) to ensure the circulation of the air.
Caution: Monitor fluid level in the tank and, if necessary, refill heat transfer fluid to
prevent air entering the solar circuit.
 Flush the solar circuit with the fluid.
Check at the inspection window of the filter (8) or through the tank opening if there are still
air bubbles in the heat transfer fluid. Continue flushing until there is no air remaining in the
fluid.

End of operation

After filling and flushing the solar system:
 Switch off pump.
 Close fill and vent valve at the solar station.
 Open stop valve between fill and vent valve.
The pressure that is generated between pump outlet and fill valve when flushing the pipe
can be released by opening the filter at the pump inlet. It will be easier then to unscrew the
filling hose (1) from the fill valve.
Caution: Collect escaping pumped media in a container.
 ROSOLAR PUMP: Unscrew the filter casing (8) and flush remaining liquid.
ROSOLAR PUMP PLUS: Turn the green handwheel of the drain valve at the pump outlet
and let the remaining liquid run out.
 Unscrew the filling hose (1) from the fill valve.
 Unscrew return hose (2) from vent valve en.
 Screw open hose ends together with the provided connecting piece in order to avoid
dripping or escaping of fluid during transport.

Care and maintenance

Danger of death due to electric shock!
Prior to work on the pump, always disconnect the drive from the power supply.
Danger of environmental damage due to hazardous pumped media!
Collect escaping pumped media and dispose of according to the locally applicable
regulations.
Connections: Check regularly if hose couplings are tight.
Cleaning the filter: There is a built-in fine filter on the suction side of the pump to filter out sold
and welder residues. Check the inspection window at the filter regulraly and clean the filter
when you see dirt deposits on the strainer:
 Screw off the filter casing (8), remove the strainer and clean both with rinsing water or
compressed air.
