2 Safety

These instructions contain important information which must be followed when installing and oper-

ating the pump. These operating instructions must therefore be read before assembly and commis-

sioning by the installer and the responsible operator.

Both the general safety instructions in the “Safety precautions” section and those in subsequent

sections indicated by danger symbols should be carefully observed.

2.1 Indication of instructions in the Operating Instructions

Safety precautions in these operating instructions which, if not followed, could cause personal injury

are indicated by the symbol:

when warning of electrical voltage with

The following symbol is used to indicate that by ignoring the relevant safety instructions, damage

could be caused to the pump/machinery and its functions:

ATTENTION!

2.2 Personnel qualifications

The installation personnel must have the appropriate qualifications for this work.

2.3 Danger in the event of non-observance of the safety instructions

Non-observance of the safety instructions can result in risk of injury to persons and damage to

pump/installation. Non-observance of the safety instructions can result in the loss of any claims for

damages.

In detail, non-observance can, for example, result in the following risks:

Failure of important functions of the pump/installation,

Failure of specified maintenance and repair procedures,

Risks to persons through electrical, mechanical and bacteriological effects,

Property damage.

2.4 Safety instructions for the operator

The existing directives for accident prevention must be adhered to. Danger from electrical current

must be eliminated. Local directives or general directives [e.g. IEC, VDE etc.] and local power supply

companies must be adhered to.

Risks through mechanical or bacteriological effects must be prevented. Local conditions and

guidelines relating to sewage technology must be adhered to.

2.5 Safety instructions for inspection and installation work

The operator must ensure that all inspection and installation work is carried out by authorised and

qualified personnel, who are sufficiently informed from their own detailed study of the operating

instructions.

Work to the pump/installation must only be carried out when at a standstill.

2.6 Unauthorised modification and manufacture of spare parts

Modifications to the pump/installation are only permissible after consultation with the manufacturer.

Original spare parts and accessories authorised by the manufacturer ensure safety. The use of other

parts can nullify the liability from the results of their usage.

English

2.7 Improper use

The operational safety of the supplied pump/unit is only guaranteed for conventional use in accor-

dance with section 1 of the installation and operating instructions. The limit values must on no ac-

count fall under or exceed those specified in the catalogue/data sheet.

3 Transport and interim storage

ATTENTION! The pump may only be transported/suspended on the handle provided for trans-

port. Never by the cable. The pump must be protected against physical damage

The pump mustn’t get into contact with flammable parts (clothes..) while using.

If the Pump is not used for longer time it should be disconnected from the elec-

trical supplyment.

4.1 Pump description (Fig. 1)

Pos. 1 Filling- / bleeding plug Pos. 4 Handle

Pos. 2 Drain plug Pos. 5 Discharge port

Pos. 3 Suction port

The Self priming Pump Wilo LP is driven by a dry-running motor which is fixed by screws with the

pump housing. Motor and pump have a continuous shaft made of stainless steel. The impellers ma-

terial is bronze. The pump housing is made of polypropylene plastics. The flow medium enters from a

horizontal suction opening and exits by the vertical pressure connection. Both connections are

equipped with 1 ½ “ plastic flanges.

4.2 Products delivered

Installation and operating instructions

Plastic flanges 1 ½“. Suction and pressure.

4.3 Accessories

Accessories must be ordered separately

Suction side: Use special hoses for suction use

5 Assembly / Installation

The LP40 pumps are intended for the following types of installation

transportable dry installation

stationary dry installation

5.1 Assembly

The pump must be installed in a frost-free place.

The shaft must be free from coarse solids (e.g. building rubble) prior to installation and commis-

sioning.

See catalogue for installation dimensions

The pressure-pipe must show the pump’s nominal width (R 1½, possibility for expansion).

The suction flange and pipe must be absolutely tight. Otherwise no suction mode.

English

5.2 Electrical connection

Electrical connection should be made by a qualified electrician. Current national regula-

tions must be observed (e.g. VDE regulations in Germany).

Check that the mains current and voltage comply with the data on the rating plate

Mains fuse: 16 A, time-lag

Pump/installation must be earthed in compliance with regulations

In accordance with EN 60335, submersible driven-motor pumps with less than 10 m of connect-

ing cable are only permitted for use within buildings, in other words not for operation in open

air.

6 Operation

To reach a optimum suction-process, it is necessary to fill the pump housing with water using the

hopper cap

7 Maintenance

In order to avoid infection maintenance work should only be carried out using protective

gloves.

For all maintenance and repair work the pump is to be switched off-circuit and pro-

tected against unauthorised re-starting.

In principle, damage to the connecting cable should only be repaired by a qualified elec-

trician.

ATTENTION! The mechanical seal must not run dry!

-Dry running reduces the life of motor and mechanical seal.

-Fill in some water !

8 Problems, causes and solutions

Problem Causes Solutions

Pump does not run no voltage Check wires and fuses and/or switch auto-

matic circuit-breakers back on in distribu-

tion substation

Rotor blocked Clean casing and impeller

Cable break

Check cable resistance. If necessary, replace

cable. Only use original Wilo special cable!

Pump has no power The pump sucks in air due to

an overly strong check the

function/adjustments of the

drop in the liquid level

Check the liquid level

Pump working against insu-

lating air cushion

Fill the pump housing with water.

Pressure-pipe blocked Check and clean line

No suction Hose (suction side leaky) Repair or change suction hose.

If no solution can be found, please contact your plumbing and heating specialist or your nearest
