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 AP pumps are designed for pumping:
• wastewater,
• sludge-containing water, and
• groundwater.
If permitted by local laws and regulations, the
GRUNDFOS AP65 pumps may be used for the
pumping of sewage from single and multifamily
houses.
GRUNDFOS AP65 pumps can also be used for the
pumping of sewage from restaurants, hotels, camp-
ing 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.
1.2 Operating conditions
1.2.1 PH-value
AP pumps in permanent installations can cope with
pH-values ranging from 4 to 10.
1.2.2 Liquid temperature
Liquid temperature: 0°C to +40°C.
For short periods up to +60°C.

1.2.3 Density of pumped liquid
Maximum density of pumped liquid: 1100 kg/m

2. Safety
7
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 longr 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 50 and 51.
Pumps for permanent installation can be installed on
a stationary auto-coupling and operated completely
or partially submerged in the pumped liquid.
1. Drill mounting holes for guide rail bracket on the
inside of the pit and fasten the guide rail bracket
provisionally with two screws.
2. Place the auto-coupling base unit on the bottom
of the pit. Use a plumb line to establish the cor-
rect positioning. Fasten with heavy-duty expan-
sion bolts. If the bottom of the pit is uneven, the
auto-coupling base unit must be supported so
that it is level when being fastened.
