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.

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.

5. Electrical connection

The electrical connection of the pump must be carried

out according to local regulations.

The operating voltage and frequency are stated on

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.

Make sure that there are at least 3 metres

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.
