Operation; Switching The Pump On; Setting The On And Off Height; Adjusting The Pump Foot (Drain 9500) - AL-KO SUB 6500 Betriebsanleitung

Operation

■
Operate the pump suspended from a cable or
pay attention to a stable position of the pump
(upright or horizontal).
■
Operate the pump only when it is fully im-
mersed.
■
Make sure there is adequate clearance under
the pump.
■
Never allow the pump to run against a closed
pressure line.
■
When using in shafts, make sure the size is
adequate.
■
Always cover the shaft with a secure foot-
plate.
7 OPERATION
7.1

Switching the pump on

IMPORTANT! Danger of damage to the
pump! The pump must not draw in any solid ma-
terial. Sand and other abrasive materials in the
pumped medium will destroy the pump.
■
Ensure that no solids can enter the pumped
medium.
NOTE Use a suitable plate to ensure stable
standing of the pump on muddy, sandy or stony
ground.
1. Unwind the mains cable (01/6) completely.
2. Ensure that electrical plug connections are
located in the area safe from flooding.
3. Set the ON and OFF height (see chapter 7.2
"Setting the ON and OFF height", page 15).
4. DRAIN 9500 only: Adjust the adjustable
pump foot (see chapter 7.3 "Adjusting the
pump foot (DRAIN 9500)", page 15).
5. Slowly immerse the pump in the pumped me-
dium, holding the immersion pump at a slight
angle so that any trapped air can escape.
6. Insert the mains plug into the power socket.
7.2

Setting the ON and OFF height

The cable of the float switch (03/2) is clamped to
cable clamp (03/1). The switching points of the
float switch can be set individually by changing
the clamping position. Recommended cable
length on the float switch approx. 120 mm.
SUB 8500 / DRAIN 9500 only: For continuous
operation, the cable of float switch (03/2) can be
connected to continuous operation terminal
(03/3).

IMPORTANT! Danger of damage to the
pump! There is a danger during pumping out that
the pump could run dry and cause equipment
damage.
■
Monitor the pump continuously when pump-
ing out to the residual water level and avoid
the pump running dry.
■
Take the pump out of service when the resid-
ual water level is reached by pulling out the
mains plug.
NOTE If the water drops below the residual
water level, the pump will draw air in. In this case,
the pump must be vented when the water level
rises and before using it again.
7.3

Adjusting the pump foot (DRAIN 9500)

The size of the suction slots (01/8) can be re-
duced using the adjustable pump foot (04/1). The
water is then drawn off at a shallower level,
coarser materials are no longer drawn in and the
delivery rate is reduced.
■
Turn the adjustable pump foot in anti-clock-
wise direction (04/a) to reduce the size of the
suction slots.
■
Turn the adjustable pump foot in clockwise
direction (04/b) to increase the size of the
suction slots.
7.4

Switching the pump off

1. Remove the mains plug from the plug socket.

8 MAINTENANCE AND CARE

8.1

Cleaning the pump

NOTE After conveying swimming pool water
containing chlorine or fluids that leave residues,
the pump must be flushed out with clear water.
1. Clean suction slots (01/8) with clear water, if
necessary.

9 HELP IN CASE OF MALFUNCTION

DANGER! Danger of electric shock!
There is a risk of electric shock when working on
the pump.
■
Disconnect the mains plug before starting
any fault remedying work.
■
Faults in the electrical system must be recti-
fied by a qualified electrician.
