controller, see the installation and operating
instructions of the controller.
For faults related to the pumps, see the installation
and operating instructions of the pumps.
13. Disposing of the product
This product or parts of it must be disposed of in an
environmentally sound way:
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.

a product means that it must be
disposed of separately from household
waste. When a product marked with this
symbol reaches its end of life, take it to a
collection point designated by the local
waste disposal authorities. The separate collection
and recycling of such products will help protect the
environment and human health.
WARNING
Biological hazard
Death or serious personal injury
- Wear protective gloves, close the
isolating valves and drain the tank
before you start any work on the tank.
Fault
Cause
Remedy
1.
The pump does
not start.
a)
The float switch is blocked in low
position.
1. Make sure that the float switch can
move freely.
2. It may be necessary to adjust the
cable length. See section
.
b)
The pump cable is defective.
Repair or replace the cable.
2.
The pump does
not stop.
a)
The float switch is blocked in high
position.
1. Make sure that the float switch can
move freely.
2. It may be necessary to adjust the
cable length. See section
.
3.
The pump starts
and stops
randomly.
a)
The float switch is not set properly.
Adjust the cable length of the float
switch. See section
.
b)
The level sensor tube is not fixed
properly in the tank and is moving up
as the liquid rises. The sensor receives
wrong signals.
Fix the tube to the tank. See fig.
.
c)
The float switch cannot move freely
because the pump has moved.
Position the pump according to fig.
or
4.
The tank is not
emptying although
the pump is
running.
a)
There is an airlock in the pump
impeller. The pump cannot build up
pressure.
Drill a hole of maximum 6 mm in the
connecting pipes in the tank. The air is
pushed out when the pump starts, and
the pump builds up pressure. The
pressure loss due to the hole is
negligible.
Do not drill a hole in the outlet pipe
outside the tank.
5.
The pump makes
an unusual sound.
a)
The pump is blocked.
Take the pump out of the tank and
remove the blockage. You may need
to dismantle the pump. See the
installation and operating instructions
of the pump.
