2. Starting up

2.1 Wall bracket

First secure the wall bracket (B pump set) in a sheltered,
yet easily accessible place so that the pump can be stored
away correctly whenever it is not in use. Storing the
pump in an upright position extends its service life and
protects the pump tube against damage and deformation.
Care must be taken to prevent any remaining liquid from
dripping onto the floor after pumping hazardous liquids
(see Fig. 2).

2.2 Suitability check

Check the following points before starting up the
pump:
Power supply?
The voltage specified on the rating plate must match that
provided by the mains supply.
Temperature?
The temperature of the medium must not exceed the
values specified in table  (see page 10).
Viscosity and density?
The viscosity or the specific density of the liquid must
not exceed the values listed in table  (see page 10),
otherwise the motor will be overloaded: In case the
viscosity and density of the liquid are higher than water,
the respective maximum value is reduced.
Resistance?
Check that the pump materials are compatible with the
medium being pumped (e.g. Lutz-catalogue resistance
table). All parts coming into contact with the medium are
made of materials as listed in table  (see page 10).

3. Operation

The motor must not be immersed in the liquid
being pumped (see Fig. 3, above).
The pump must not be used to pump flammable
liquids (see Fig. 3, below).

3.1 Motor overload

The overcurrent release integrated into the motor swit-
ches off automatically if the pump is overloaded. The
motor switch must be set to „0" in this case (see Fig.
4 - Item 2). Allow the motor to cool, then press the red
button on the overcurrent release (see Fig. 4 - Item 1)
and switch the pump on again.

4. Maintenance and care

The pump must be thoroughly rinsed whenever it has
been used in aggressive, adhesive or highly contaminated
liquids (see Fig. 5).
Substances containing aromatic or chlorinated hydro-
carbons (acetone, thinner) must not be used to clean
the pump housing.
The hose and hose connections must be inspected re-
gularly for leaks and damage.
The connecting cable must be inspected regularly to
ensure safety in operation.
There are leakage openings in the motor connection. The
pump must be sent in for repair if any liquid emerges
from these openings (see Fig. 6).

5. Repairs

Repairs may only be carried out by the manufacturer or
authorized repair shops. Only use genuine Lutz spare
parts.
When returning the device to the supplier it is compulsa-
ry to attach the decontamination certificate duly filled
out and signed by the operator (see service area www.
lutz-pumpen.de).
