Connecting a separate suction hose (03/ 04)

IMPORTANT! Danger of damage to the
pump! The pump will not function correctly if the
tapping point is 18 m higher than the pump.
■
Ensure that the tapping point is not more
than 18 m above the water level.
IMPORTANT! Danger of damage to the
pump! The pump cannot be vented if the sepa-
rate suction hose is not filled with water.
■
Fill the separate suction hose with water to
ensure the proper function.
The port (03/1) for a separate suction hose, e.g. for
"floating tapping" of water from the upper half of a
cistern (04/1) is on the underside of the pump.
Pumping via the separate suction hose prevents
water being drawn in via the inlet screen. Water is
pumped off only via the additionally installed suction
hose (04/3). A float switch (04/2) can also be at-
tached to the suction hose. This allows the water on
the surface of the cistern to be pumped off.
■
DIVE 6500/34: The pump is switched on and
off by the float switch, depending on the wa-
ter level.
■
DIVE 5600/44: The pump is switched on and
off automatically by the integrated pressure
switch.
1. Open cover on the underside of the pump
(03/a). Use tools, if necessary.
2. Fill the pump with water until it overflows.
3. Install gasket and cover with thread (03/b).
4. Connect the suction hose (03/c).
5. Fill the suction hose with water on the suction
side.
6. Place the pump (04/4) into the cistern.

6 START-UP

IMPORTANT! Risk of flooding! In the event
of faults in the pump,water can escape and
cause consequential damage due to flooding.
■
Take appropriate measures to avoid conse-
quential damage caused by flooding in the
event of faults in the pump.
IMPORTANT! Danger of damage to the
pump! If pressure lines are not completely
drained, the pump cannot vent itself automatically
and the pump may be damaged.
■
Before switching on again after removing
from the shaft, ensure that the pressure line
is completely drained.

■
Operate the pump suspended from a cable
(01/8) 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.
NOTE The pump (DIVE 5600-44) has a
check valve on the pump outlet. This prevents
the pressure line being drained each time the
pump stops.

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 On muddy, sandy or stony ground,
use a suitable plate to ensure the stability of the
pump or connect a separate suction hose.
1. DIVE 5600/44 only: Open all shut-off devices
(valve, spray nozzle, water cock) in the pres-
sure line.
2. Unwind the mains cable (01/ 6) completely.
3. Ensure that electrical plug connections are
located in the area safe from flooding.
4. DIVE 6500/34 only: Set the ON and OFF
height (see chapter 7.2 "Setting the ON and
OFF height (DIVE 6500/34)", page 16).
5. Slowly immerse the pump in the pumped me-
dium, holding the 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 (DIVE
6500/34)
The cable of the float switch (01/9) is clamped to
the pump housing (01/5). The switching points of
the float switch can be set individually by chang-
