2. Product introduction
2.1 Pumped liquids
Grundfos APG pumps are designed for pumping:
• wastewater
• sludge-containing water
• groundwater
• sewage from restaurants, hotels, campsites and
other facilities.
The compact design makes the pumps suitable for
both temporary and permanent installation. They are
also suitable for free-standing installation as well as
installation on an auto-coupling system.
APG pumps are equipped with a cutter system which
cuts all destructible solids into small pieces so that
they can flow through relatively small diameter pipes.
The pumps must not be used for
pumping combustible, flammable or
corrosive liquids.

8. Maintenance and service
4.1 Installation requirements
Pump installation in pits must be carried
out by specially trained persons.
DANGER
Electric shock
Death or serious personal injury
‐It must be possible to lock the main
switch in position 0. Type and
requirements are specified in EN
60204-1.
DANGER
Electric shock
Death or serious personal injury
‐Make sure that there is at least 3 m
free cable above the maximum liquid
level.
Maintenance and service work must be
carried out when the pump is outside the
pit. For safety reasons, all work inside pits
must be supervised by a person outside
the pit.
WARNING
Crushing hazard
Death or serious personal injury
‐Make sure that the lifting bracket is
tightened before lifting the pump.
4.2 Installation on auto coupling
Pumps for permanent installation can be installed on
a stationary auto-coupling base and operated
completely or partially submerged in the pumped
liquid.
Make sure that the pipes are installed
without the use of undue force. No loads
from the weight of the pipes must be
carried by the pump. Use loose flanges to
ease the installation and to avoid pipe
tension at the flanges.
7
English (GB)
Do not use elastic elements or bellows to
connect the pipes.
In some installations, a plinth is required
beneath the auto coupling to ensure the
correct installation of the pump.
The free end of the cable must not be
submerged as water may penetrate into
the motor.
1. Drill mounting holes for the guide-rail bracket on
the inside of the pit, and fasten it provisionally with
two screws.
2. Place the auto-coupling base unit on the bottom
of the pit. Use a plumb line to establish the correct
position. Fasten the auto-coupling base unit with
heavy-duty expansion bolts. If the bottom of the
pit is uneven, the auto-coupling base unit must be
supported so that it is level when fastened.
3. Assemble the discharge line according to the
procedures and without exposing it to distortion or
tension.
4. Insert the guide-rails in the rings of the auto-
coupling base unit, and adjust their length to the
guide rail bracket accurately.
5. Unscrew the provisionally fastened guide rail
bracket, fit it on top of the guide-rails, and fasten it
to the pit wall firmly.
6. Clean any debris from the pit before lowering the
pump into it.
7. Fit the auto coupling to the discharge port of the
pump. Slide the guide bar of the auto coupling
between the guide rails, and lower the pump into
the pit by using a chain. When the pump reaches
the auto-coupling base unit, it automatically
connects tightly.
8. Hang the end of the chain on a suitable hook at
the top of the pit.
9. Adjust the length of the motor cable by coiling it
up on a relief fitting so the cable is not damaged
during operation. Fasten the relief fitting to a
suitable bracket at the top of the pit. Make sure
that the cables are not sharply bent or pinched.

4.3 Free-standing installation
The free end of the cable must not be
submerged as water may penetrate into
the motor.
If several pumps are installed in the same
pit, the pumps must be installed at the
same level to allow optimal pump
alternation.
APG pumps are provided with a separate base stand.
For free-standing installation of the pumps, fit a 90°
elbow on the discharge port. The pumps can be
installed either with a hose or a rigid pipe and valves.
Pumps for submerged ring-stand installation can
stand freely at the bottom of the pit or at any similar
location.
If a hose is used, make sure that it does not buckle
and that its inside diameter matches the outlet.
If a rigid pipe is used, fit the parts in the following
order:
1. union or coupling
2. non-return valve
3. isolating valve.
If it is installed in muddy conditions or on uneven
ground, place the pump on bricks.
1. Fit a 90° elbow to the pump outlet and connect
the outlet pipe or hose.
2. Lower the pump into the liquid using a chain
secured to the lifting bracket. Place the pump on a
plain, solid foundation.
3. Hang the end of the chain on a suitable hook at
the top of the pit. Make sure that the chain cannot
come into contact with the pump housing.
4. Adjust the length of the power cable by coiling it
up on a relief fitting to ensure that the cable is not
damaged during operation. Fasten the relief fitting
to a suitable hook at the top of the pit. Make sure
that the cables are not sharply bent or pinched.
5. Connect the power cable and the control cable, if
any.

the nameplate. Voltage tolerance: ± 10 % of the
voltage stated on the nameplate. Make sure that the
motor is suitable for the power supply available at the
installation site.
DANGER
Electric shock
Death or serious personal injury
‐Connect the pump to an external main
switch, which ensures all-pole
disconnection with a contact
separation according to EN 60204-1.
‐It must be possible to lock the main
switch in position 0. Type and
requirements as specified in EN
60204-1.
The permanent installation must be fitted
with an earth-leakage circuit breaker.

of free cable above the maximum liquid
level.
DANGER
Electric shock
Death or serious personal injury
‐If the power cable is damaged, it must
be replaced by the manufacturer, a
service agent or a similarly qualified
person.
Set the motor-protective circuit breaker to
the rated current of the pump. The rated
current is stated on the nameplate.
The supply voltage and frequency are marked on the
nameplate. Make sure that the power supply at the
installation site is suitable for the pump motor.
All pumps are supplied with a 10-metre cable and a
free cable end.
DANGER
Electric shock
Death or serious personal injury
‐Before the first startup, check the cable
for visible defects to avoid short
circuits.
The pumps must be connected to one of the
following:
• a control unit with motor-protective circuit breaker,
such as Grundfos CU 100
• Grundfos LC 231 or 241 pump controller.
Pumps cannot be operated with frequency
converter.
5.1 Level controllers
The liquid level can be controlled by the Grundfos LC
level controllers.
Suitable level controllers:
• LC 231: compact solution with certified motor
protection for single- and dual-pump versions.
• LC 241: cabinet solution offering modularity and
customisation for single- and dual-pump versions.
In the following description, "level switches" can be air
bells, float switches or electrodes depending on the
selected pump controller.
Depending on the security levels and the number of
pumps, level switches can be used in the following
setups:
• Dry run (optional)
• Stop
• Start pump 1 (single-pump version)
• Start pump 2 (dual-pump version)
• High level (optional)
Analogue level transmitters can be used, and all
levels can be customised. Level switches can be
used with level transmitters, for dry-run protection and
high level alarm.
The pump must not run dry. Install an
additional level switch to ensure that the
pump is stopped in case the stop level
switch is not operating.
