rubber, H07RNF type, according to DIN 57282 or DIN
57245 standards.
Never touch, lift or carry with a cable a pump
connected to network (pic. E)
It is necessary to make sure the connecting socket was not
near water and humidity and the plug was protected against
humidity.
Before putting the pump into operation, check whether the
electric cable and/or socket are not damaged.
Before any work on the pump, pull the plug out of the
socket.
Instructions step by step
•
Connect the water hose to appropriate pump outlet (see
the Assembly and first putting into operation).
•
Fix the rope, chain, etc. to the pump handle and place it
to the right place.
•
Put the pump "sideways" (pic. D) to the pumped
medium. Make sure the floating switch is in the operating
position.
•
Plug in the pump.
•
Rinse the pump with clean water after work finishing.
Floating switch positions (pic. B + C)
The operating or shutdown point of the pump can be set
with various floating switch positions. In pic. B you can see
the float cable without any fixation change with full switch
radius. The figure 1 is the working position and figure 0 the
shutdown position.
Due to appropriate fixation of the float cable, possible on the
pump handle, the switch radius can be reduced when there
is no sufficient space or at a corresponding level control.
The figure 1 in pic. C is the working position and figure 0
the shutdown position.
Failures – causes - removal
(problem):
Engine does not start
(cause):
1.
No system voltage
2.
Blocked pump wheel
3.
Floating switch in shutdown position
(measures):
1.
Check the voltage
2.
Inspect the pump wheel for foreign
objects
3.
Check the water level (pic. B/C)
(problem):
Pump does not suck
(cause):
1.
Pump without water
2.
Water level too low
3.
Blocked pump wheel
(measures):
1.
Let the air bubbles release (pic. D)
2.
Switch the pump off, water level
must go up.
3.
Remove the obstruction
(problem):
Insufficient amount of water pumped
(cause):
1.
Dirty tube filter
2.
Water level quickly going down
3.
Maximum head of delivery exceeded
4.
Transport guide broken
(measures):
1.
Clean the tube filter
2.
Ensure sufficient inflow
(problem):
(cause):
(measures):
Inspections and maintenance
Except for the below-described cases, the pump must be
delivered to the customer service department for any repairs.
Sand and other abrasive solids cause premature wear and
pump power reduction. Works on the pump electric
equipment can explicitly be executed by the customer service
department only (that also applies for the electric cable and
float). The drowned sludge pumps are virtually maintenance-
free. Oilless bearings. Occasional filter support cleaning is
enough, no other maintenance is necessary. Original spare
parts must only be used in any case.
To ensure long service life of the pump seal, we
recommend rinsing the pump with clean water in regular
intervals.
Safety instructions for inspections and maintenance
It is always necessary to interrupt feeding (plug pulled out of
socket) and make sure the pump is not going to start before
any pump maintenance. Only a regularly maintained and
treated appliance can serve as a satisfactory aid. Insufficient
maintenance and care can lead to unforeseen accidents and
injuries.
