4. Starting up

First secure the wall bracket (pump set Lutz B Vario) 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 ser-
vice life and protects the pump tube against damage and
deformation (see Fig. 2). Care must be taken to prevent
any remaining liquid from dripping onto the floor after
pumping hazardous liquids.

5. Operation

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

5.1 Starting/interruption, speed control

The pump is started by turning the rotary handle (see Fig.
4 – Item 1) clockwise. While turning (see Fig. 4 – Item
2) the speed of the pump is increased simultaneously.
For stopping the rotary handle must be turned back
counterclockwise as far as it will go.
5.2 Overload of the pump
The overcurrent release integrated into the motor swit-
ches off automatically if the pump is overloaded. In this
case turn the rotary handle back to "0" (see Fig. 4 – Item
3). The pump can be restartet after a cooling period.

6. 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 for
damages.
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).

7. Repairs

Repairs should only be made by the manufacturer or
authorized Lutz-dealers. Only use genuine Lutz spare
parts.
When returning the device to the supplier it is compulsary
to attach the decontamination certificate duly filled out
and signed by the operator.
