Danger
Danger of scald burn due to high media temperature
> Fill the solar system only when cold – if necessary cover the solar
collectors.
Danger of burn due to hot motor casing
> Do not block neither suction nor pressure hose more than 1 minute
to avoid overheating of the motor.
Warning
Danger of injury due to splashing liquid
> Connect the hoses tightly to the pump.
Caution
Material damage due to dry running
> Never allow the pump to run dry for more than 1 minute.
Material damage due to tilting of the cart on uneven ground
> Operate the filling unit only on even ground.
Danger of environmental damage due to hazardous pumped media
> Collect escaping pumped media and dispose of according to the
locally applicable regulations.
Material damage due to improper storage
> Prior to extended periods of pump down time clean pump to avoid
adhesions and damage to the impeller.

7. Open tank lid 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.
8. Flush the solar circuit with the fluid.
Check at the inspection window of the
filter 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.
5. 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 from the fill valve.
Caution: Collect escaping pumped media in a container.
> Unscrew the filter casing and flush remaining liquid.
> Unscrew the filling hose from the fill valve.
> Unscrew return hose from vent valve.
> Screw open hose ends together with the provided connecting piece in order to
avoid dripping or escaping of fluid during transport.

6. Maintenance
Danger
Danger of death due to electric shock
> Prior to work on the pump, always disconnect the drive from the
power supply.
Caution
Danger of environmental damage due to hazardous pumped media
> Collect escaping pumped media and dispose of according to the
locally applicable regulations.
6.1 Connections
> Check regularly if hose couplings are tight.
6.2 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, remove the strainer and clean both with rinsing water
or compressed air.
7. Troubleshooting

closed or tank empty Open the stop valve or fill the tank
Pump does not take in
liquid
Filter clogged Clean the filter (see
chapter 6, maintenance)
Pressure line blocked Clean pressure hose
Stop valve at the tank outlet
closed Open stop valve
Pump does not build up
pressure
Filter clogged Clean the filter (see
chapter 6, maintenance)
