connection, and maintenance of

the product must be carried out by

an authorized electrician in

accordance with the National

Electrical Code and any state, local

governing codes and regulations.

cannot be accidentally switched

on.

DANGER

Electric shock

Death or serious personal injury

- Pump installation in a sump pit,

basin or tank must be carried out

by qualified, specially trained

persons in accordance with the

National Electrical Code and any

state, local governing codes and

regulations.

English (US)

4.1 Pipe connection

Threaded steel or rigid plastic pipes can be screwed

directly into the 2" NPT outlet port. For permanent

installation, we recommend that you fit a union, a

non-return valve and an isolating valve in the outlet

pipe.

Other recommendations:

• For portable or temporary installations, a plastic

outlet pipe can be used in conjunction with a

suitable, screwed connection or a hose coupling.

• Threads must be sealed using Teflon®tape.

4.2 Minimum space

When the pump is installed in a permanent

installation with a float switch, and the cable length is

set to the minimum length of at least 4 inches (100

mm), the minimum dimensions of the sump pit, basin

or tank must be as shown in fig. 2.

In addition, the sump pit, basin or tank must be sized

according to the relation between the water flow to

the sump pit, basin or tank and the pump

performance.

Fig. 2 Minimum installation dimensions

DANGER

Electric shock

Death or serious personal injury

- Route the power cable in a way

that supports it and protects it from

being cut, pinched or damaged.

- If the power cable is cut, pinched,

or damaged, replace it before

using the product.

DANGER

Electric shock

Death or serious personal injury

- Do not remove the power cable

and strain relief.

- Do not connect electrical conduit to

the pump.

WARNING

Moving parts

Minor or moderate personal injury

- Make sure that persons cannot

come into contact with moving

parts.

If the pump is used without a float

switch, use an approved level

controller with a motor protection unit

and set the current rating to match the

nominal current marked on the

product's nameplate.

Do not lift the pump by the power

cable or by the outlet pipe or hose.

If the pump is installed in a well or

tank, lower and lift it by means of a

wire or chain fastened to the pump

handle.

Do not install the pump hanging from

the outlet pipe or hose.

4.3 Location

The pump can be used in vertical as well as

horizontal position. See fig. 3.

During continuous operation, the motor and the inlet

strainer must be completely covered by the pumped

liquid.

Fig. 3 Pump positions

When the pipe or hose has been connected, place

the pump in its operating position.

Position the pump so that the inlet strainer will not be

blocked by sludge, mud or similar materials.

In a permanent installation, the installation site must

be cleared of sludge, pebbles, etc. before the pump

is installed.

We recommend that you place the pump on a solid

base. See fig. 4.

Fig. 4 Pump placed on a plate

4.4 Free-standing installation

See fig. A, page 16.

For free-standing installation of the pumps, fit a 90 °

elbow to the outlet port. The pump can be installed

with a hose or rigid pipe and valves.

In order to facilitate service of the pump, fit a flexible

union or coupling to the outlet line for easy

separation.

If a hose is used, make sure that the hose does not

buckle and that the inside diameter of the hose

matches that of the outlet port.

If a rigid pipe is used, fit the union or coupling, non-

return valve and isolating valve in the order

mentioned, as seen from the pump side.

Lower the pump into the liquid.

If the pump is installed in muddy conditions or on

uneven ground, we recommend that you support the

pump on bricks.

4.5 Adjustment of cable length for a float

switch

The difference in level between start and stop can be

adjusted by changing the free cable length between

the float switch and the pump handle.

• An increased free cable length will result in fewer

starts and stops and a large difference in level.

• A reduced free cable length will result in more

frequent starts and stops and a small difference

in level.

The free cable length must be a minimum of 4 inches

(100 mm) and a maximum of 14 inches (355 mm).

The stop level must be above the pump inlet to

prevent the pump from taking in air.

Fig. 5 Start and stop levels

The start and stop levels vary according to the cable

length.

Manual operation can be achieved in one of two

ways:

• Unplug both the pump and the float switch from

the wall socket. Insert the pump plug into the wall

socket.

• Keep the float switch in a high position by

attaching it to the outlet pipe or hose.

The electrical connection must be carried out in

accordance with local regulations and follow the

National Electrical Code (USA) and the Canadian

Electrical Code. The pump must be grounded. The

operating voltage and frequency are marked on the

nameplate. Make sure that the motor is suitable for

the power supply on which it will be used.

Power supply

• 1 x 115 V, 60 Hz

• 1 x 230 V, 60 Hz.

To connect the pump for manual operation, insert the

pump plug into a wall socket. If a float switch is

included for automatic operation, it will be of the

"piggy-back" design. Insert the float-switch plug into

the wall socket, and insert the pump plug into the

back of the float-switch plug.

Motor protection

The Unilift AP B pumps have built-in thermal

overload protection and require no additional motor

protection. If the motor is overloaded, it stops

automatically. When cooled to normal temperature,

the motor starts automatically.

5. Starting up the product

WARNING

6. Starting

Before starting the pump, check that the following

requirements are fulfilled:

• The pump is submerged in the liquid. During

normal operation, the pump must be below the

surface of the liquid. See fig. 5.

• The pump is placed on a base so that the pump

inlet is not blocked by silt, mud or similar

materials.

• The pipe or hose connection is tight.

• The outlet pipe or hose is open, that is the hose

is not bent, etc.

• The pump is connected to the power supply in

accordance with the instructions.

• For pumps with a float switch, check that the float

switch can move freely. See section

4.5 Adjustment of cable length for a float switch.

Startup procedure

1. Switch on the pump and check:

– that the pump is operating properly

– that water is being pumped.

2. For pumps with a float switch, check that the float

switch will allow the pump to pump down to the

chosen level according to fig. 5.

3. If you want to pump below this level, hold the

float switch in the vertical position.

7. Product introduction

7.1 Product description

The Grundfos Unilift AP35B and AP50B pumps are

single-stage, submersible pumps designed for the

pumping of wastewater.

The pump is designed for automatic operation with a

float switch or for manual operation.

The pump can be installed in a permanent

installation, on auto-coupling or as a free-standing

pump, or used as a portable pump.

The pumps are capable of pumping water containing

a limited quantity of solids without being blocked or

damaged.

7.2 Applications

Incorrect use of the pump, for example resulting in

blockage or wear of the pump will void the pump's

warranty. Note that the pump is not suitable for these

liquids:

• liquids containing long fibers

• flammable liquids (oil, gasoline, etc.)

• aggressive liquids.

• liquids containing solids exceeding the pump's

recommended maximum particle size.

The pump is capable of pumping water containing a

limited quantity of spherical particles. See

section Maximum particle size on page 15.

Pumping of spherical particles exceeding the

maximum particle size for the pump may block or

damage the pump.

DANGER

Electric shock

Death or serious personal injury

- Do not use the pump in or at

swimming pools, garden ponds,

etc. when there are persons in the

water.

If the pump has been used for very

dirty or chlorinated water, flush the

pump thoroughly with clean water

after use.

Wear gloves and other suitable

personal protective equipment in

accordance with local regulations.

Observe local regulations on any

exposure to wastewater.

The product is not designed for

pumping stones and similar materials.

English (US)

The pump is suitable for the following applications.

See the following Applications table.

* Check the regional or local EX-approval requirements for surface water at gas stations and in parking

areas.

Note: Unilift AP B does not have any explosion-proof approval. See Grundfos SL range.
