control shall be carried out with the device turned off and output valve open.
Frost protection
In danger of freezing (the temperature drops below 0°C in areas the device is
being operated), it is strictly recommended to fully empty the whole system,
including the pump and pipes. Water freezing inside the system may result in
serious waterworks damage or hot water injury (see General safety
instructions).
1) Disconnect the plug from a power supply
2) Open the pressure branch valves and wait until the water pressure
drops to the level when water stops running out from the device
3) Open the output bolt and let water escape the system. Place a
container under the output bolt to prevent escaping water from causing
any damage
4) Place the output bolt back after finishing the process
5) Store the pump in a dry area and keep away from children, when not
installed permanently
6. Troubleshooting
Defect
Cause
Repair
The engine is not working
The el. current
The thermal fuse switched on
The rotor is blocked
Check the supply
Wait for the cool
Detect the fault and unlock the pump
The engine works, but the
pump does not pump liquid The suction line is not submerged in
water
The pump is not flooded
The suction line is clogged
Suction height is too large Air in
suction line
Dip the pipeline to a depth of min. 30
cm
Apply the pump with water as
instructed
Remove dirt
Check the water level
Check air suction of the suction line
The thermal fuse switches
off
The engine is overloaded with
dirt
Liquid contains too much dirt
The liquid has a temperature
higher than 35 ° C
Clean the pump
Use a suction filter
Only use cooler water
Low drawdown
Aspiration barrier
Suction height too large Pipe
diameter insufficient The
discharge height is too high
Clean suction
Reduce the suction height Use
a larger discharge pipe Reduce
the discharge height
