Manual Operation; Maintenance And Cleaning - AL-KO TWIN 10000 Combi Bedienungsanleitung

Adjusting the suction basket (Fig. D)
1. Release the suction basket by turning it to
the right (1), move upwards or downwards
(2) and lock back in by turning it to the
left (3).
Automatic operation
See technical data for cut-in on and cut-
off levels.
In automatic operation, place the suc-
tion basket into the "bottom" position in
order to achieve the greatest possible
pumping output.
1. Plug the pump into the socket and set the
operation selection switch to "AUTO" (Fig.
F). As soon as the pump has reached the
cut-in (= START) level, the float switch will
automatically switch the pump on. When the
liquid has fallen below the cut-off (=STOP)
level, the pump will automatically switch off,
see technical data.
Take suitable measures, e.g. installation
of an alarm or a back-up pump, to ensure
that flooding will not occur if the pump
should malfunction.
Make sure that the pump does not run on
a blocked or closed pressure hose.

Manual operation

In manual operation, the water can be
pumped out up to a residual water level of
approx. 5 mm.
The minimum water level for operation
must be 6 cm.
Pumping out remaining liquid
Before you can pump out any remaining liquid,
set the suction basket to "top" position and pro-
ceed as follows:
1. Plug the electric cable into the socket and
set the operation selection switch to "MAN"
(Fig. F). The pumping will begin.
If the water level is lower than 6 cm the
pumping will be accelerated if, after 30 s
of operation, you switch the pump off and
back on for 1 – 2 s. Repeat this several
times, if necessary.
While pumping out remaining liquid, make
sure to keep the pump under constant
observation and avoid allowing the pump
to suck air. Upon reaching the residual
water level, switch the pump off by
switching the operation selection switch
to "AUTO". The pump will then switch
back on for automatic operation when the
cut-in level is reached.
If the level of the remaining water drops
below 5 mm, the pump will suck in air.
Before using the pump again to drain
liquid, the air trapped in the pump will
have to be let out (see Setting up and
Operating the Pump).
Adjusting the cut-in and cut-off levels
The float switch cable is attached to the
pump housing. You can adjust the cut-in =
START and cut-off = STOP levels for opera-
tion by simply changing the height of the
switch as desired. Recommended length of
the float switch cable is approx. 120 mm.
Switching off the Pump
1. To switch off the pump, just pull the plug of
the electric cable from the socket.

Maintenance and Cleaning

Before beginning any maintenance or
cleaning work, make sure that the pump
has been unplugged and take precautions
to ensure that it cannot be switched on
during work!
Cleaning the pump
If you have used your pump to pump chlorine
water (pool water) or liquids which leave a
residue, flush your pump out with clear water
after use.
Clean the suction openings of the suction
basket and pump base with clear water as
required.
Dismantling the suction basket (Fig. E)
1. Remove click-stop screws (3) and pull the
suction basket (2) off of the pump base (1).
2. Clean suction basket and pump base.
3. Re-mount suction basket and screw in the
click-stop screws.
