5. Before starting the equipment

Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
5.1 Installation
The equipment can be installed either:
•
Stationary with a rigid pipe line
or
•
Stationary with a flexible hose line
The equipment must be fastened to the suspensi-
on eyelet with a rope (Fig. 2/Item 6).
The maximum pumping rate is possible only with
the largest possible line diameter; if smaller hoses
or pipes are connected, the pumping rate will be
reduced. If the universal hose connection (Fig. 1/
Item 1) is used, it should be shortened (as shown
in Fig. 9) to the connection actually used in order
not to reduce the pumping rate unnecessarily.
Flexible hoses must be fastened to the universal
hose connection with a hose clip (not included in
the scope of supply).
Note!
When installing, never hang the equipment by
the discharge line or by the power cable. The
equipment must be hung up by the provided carry
handle or suspension eyelet, or it must rest on the
bottom of the shaft. To ensure that the equipment
works properly, the bottom of the shaft always
must be free of sludge and other accumulations
of dirt. If the water level is too low, the sludge
in the shaft can quickly dry out and hinder the
equipment from starting. It is necessary therefore
to check the equipment regularly (carry out trial
start-ups).
The pump shaft should measure at least 50 x 50 x
50 cm so that the fl oating switch can move freely.

5.2 Mains connection

Danger!
The equipment you have purchased comes with
an earthing-pin plug. The equipment is designed
for connection to a socket outlet with earthing
contact for 230 V ~ 50 Hz. Make sure that the
socket-outlet is suffi ciently fused (at least 6 A)
and in good working order. Insert the power plug
in the socket-outlet and the equipment is ready
for operation.

6. Operation

You can put the equipment into operation after
you have thoroughly read the installation and ope-
rating instructions. Pay attention to the following
points:
•
Make sure that the equipment is set up secu-
rely.
•
Check that the discharge line is fitted correct-
ly.
•
Make sure that the electrical connection is
230 V ~ 50 Hz.
•
Check that the electrical socket-outlet is in
good working order.
•
Make sure that no moisture or water can ever
reach the power connection.
•
Make sure that the equipment does not run
dry.
•
To switch off the equipment, pull the power
plug out of the socket outlet.
Setting the On/Off switching point:
The ON/OFF switching point can be infi nitely ad-
justed with the height adjustment facility. For this
purpose you must fi rst slacken the screw (Fig. 3,
Item 3). The switching diff erential can be infi nitely
adjusted by extending or shortening the fl oat
cable (Fig. 3).
•
The floating switch must be fitted so that the
switching point height: ON and the switch
point height: OFF can be reached easily and
with little force. Check this by placing the
equipment in a container filled with water
and carefully raising and lowering the floating
switch with your hand. You can then see whe-
ther the equipment switches on and off.
•
Make sure that the distance between the floa-
ting switch head and the cable holder is not
too smaller than 10 cm (Fig. 3). If the distance
is too small, there is no guarantee that the
equipment will work correctly.
•
When adjusting the floating switch, make
sure that the floating switch does not touch
the bottom before the equipment is switched
off. Important! Risk of dry running.
