Troubleshooting - DAB VERTY NOVA 200 Installationsanweisung Und Wartung

•
It is absolutely essential to prevent any risk of the pump freezing. In the event of freezing temperatures, remove the pump from the
liquid, empty it and keep it in a place where it cannot freeze.
•
To avoid the obstruction of the suction side, periodically, it is advisable to make sure that no dirt (leaves, sand, etc.) has been
accumulated in the collection pit.
Overload protection
The pump has a thermal overload safety device. In the event of any overheating of the motor, this device automatically switches off the
pump. The cooling time is roughly 15 to 20 minutes, then the pump automatically comes on again. If the overload cutout is tripped, it is
essential to identify and deal with the cause of the overheating. See Troubleshooting.

TROUBLESHOOTING

Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove the plug from the
socket).
Fault
The motor does not start or makes no noise.
The pump delivers no water.
The pump does not stop.
The flow rate is too low.
The pump stops running (possible
intervention of the thermal overload switch).
ENGLISH
Possible causes
A) Make sure the motor is powered.
B) The pump is not enabled by the float
A) The suction grid or piping are clogged.
B) The impeller is worn or stuck.
C) The required head is too high for the
characteristics of the pump.
D) Water level under the suction
minimum.
A) The pump is not disabled by the float.
A) Make sure the suction grid is not partially
clogged.
B) Make sure the impeller or delivery pipe
are not partially clogged or fouled.
- Make sure the fluid being pumped is not
too dense, causing the motor to overheat.
- Make sure the temperature of the water
is not too high.
- Make sure there is no solid body
obstructing the impeller.
- Power supply doesn't comply with the
nameplate's data.
