Prior To Operation; Discharge Hose Connection; Installation; Operation - Elektra Beckum TP 7500 Si Instructions D'utilisation

ENGLISH
A damaged pump must be work-
manlike repaired before it can be
used again.
Do not attempt to repair the pump
yourself! When repaired inexpertly
there is a hazard of fluid entering the
electrical parts of the pump.

5. Prior to Operation

5.1 Discharge hose connec-
tion
The discharge hose is connected either
directly to the discharge port
means of the multi-adapter (11) (secure
discharge hose with hose clamps, if nec-
essary).
The check valve's flap (12) must open in
the direction indicated by the arrow. (The
marking "UP" must face the multi adap-
tor).

Note:
When using the multi adaptor cut
off any parts nor required, as they
reduce the flow unnecessarily.
5.2

Installation

Space required approx. 20 cm x
20 cm.
The pump must not be submerged
deeper into water then stated in the
"Technical Specifications".
Place pump so that the suction inlet
can not be blocked by foreign
objects (stand on a base, if neces-
sary).
Ensure sufficient upright stability.
A
Caution!
Do not lift pump at cable or dis-
charge hose; both are not designed
for the tensile load by the weight of
the pump.
Lower pump to the bottom of the
fluid container. Use a strong rope,
fastened to the handle/hanger to
lower the pump.
The pump can also be operated
when suspended by a rope.
Any possibly present air cushion in
the pump can escape through vent
10
holes when the pump is lowered into
the fluid. Venting generates air bub-
bles. This is no fault of the pump but
the effect of automatic venting.
When using the pump for the first
time it may take several seconds
before the air is vented.
To start the submersible pump plug
power cable in.
Unplug to stop the pump.

6. Operation

,
(10) or by
13
12
Before plugging in set the operating
mode with the Mode selector (13):
Position A = Automatic mode
Position M = Manual mode
6.1

Automatic mode

In Automatic mode the submersible
pump is automatically started and
stopped by the integrated float switch:
The pump starts pumping when the
float switch is raised by the fluid
above the starting level (14).
The pump stops when float switch
falls to below the cut-out level (15).
A
Caution!
The float switch must be able
to move in such way that the pump
can not run dry.
6.2

Manual mode

Starting
Push Mode selector (13) up to posi-
tion M. The pump starts pumping.
A
Caution!
Do not let run pump unat-
tended in Manual mode. Risk of dam-
age by pump running dry at low fluid
levels.
Stopping
Contrary to Automatic operation the
pump does not stop running when a cer-
tain water level is reached.
Push Mode selector (13) down into
position A. The pump stops when
the float switch lowers to below the
cut-out level .

7. Care and Maintenance

A
Danger!
Prior to all servicing:
Switch Off.
Unplug.
Service and repair work other than
described here must be left to quali-
fied specialists.
7.1

Periodic maintenance

For the pump to function perfectly at any
time periodic maintenance is required.
This also applies if the pump is used
under heavy conditions, but does not run
for extended periods of time (e.g. when
used in well drains).
Yearly service
1. Check pump casing, cables and
float switch for damage.
2. Rinse pump
Remove
algae desposits, with brush and
dishwashing liquid.
3. To flush the inside of the pump,
place it into a container filled with
clear water and switch ON briefly.
Rinsing the pump.
Always rinse the pump with clear
water when liquids were pumped
that leave residues, such as chlo-
rous water from a swimming pool.

with clear water.
