Before beginning installation procedures,
these installation and operating instruc-
tions should be studied carefully. The in-
stallation and operation should also be in
accordance with local regulations and ac-
cepted codes of good practice.
1. General description
1.1 Applications
GRUNDFOS APG pumps are designed for pumping:
• wastewater,
• sludge-containing water,
• groundwater,
• sewage from restaurants, hotels, camping sites,
etc.
The compact design makes the pumps suitable for
both temporary and permanent installation. Further-
more, the pumps are suitable for free-standing instal-
lation as well as installation by means of an auto-
coupling guide rail system.
The APG pumps are equipped with a cutter system
which cuts all destructible solids into small pieces so
that they can be led away through pipes of a rela-
tively small diameter.
1.1.1 Potentially explosive environments
Use the explosion-proof APG pump versions for ap-
plications involving the risk of explosion.
Note: The explosion classification of the pump is
EEx de IIB T4 and must in each individual case be
approved by the local authorities for use at the de-
sired installation site.

1.3 Sound pressure level
10
The sound pressure level of the pump is lower than
10
the limiting values stated in the EC Council Directive
98/37/EEC relating to machinery.
2. Safety
Pump installation in wells must be carried
out by specially trained persons.
3. Transportation and storage
The pump may be transported and stored in a verti-
cal or horizontal position. Make sure that it cannot
roll or fall over.
Always lift the pump by its carrying handle, never by
the motor cable or the hose/pipe.
For long periods of storage, the pump must be pro-
tected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay special atten-
tion to the shaft seals and the cable entry.
4. Installation
The loose nameplate supplied with the pump should
be fixed at the installation site.
Prior to installation, check the oil level in the oil
chamber, see section 7. Maintenance and service.
4.1 Installation on auto-coupling
See figs. A and B, pages 83 and 84, for pumps up to
and including 3.3 kW and
fig. D, page 86, for pumps from 4.8 kW up to and in-
cluding 9.2 kW.
