7.1.2 Portable wet installation

For portable wet installation with hose connec-
tion, the pump must be secured in the pit against
moving or falling over (e.g. fix the chain with a
small amount of tension).
NOTE:
When used in a pit without a firm base, the pump
must be put on a sufficiently large plate or hung
from a rope or a chain in a suitable position.

7.2 Electrical connection

DANGER! Risk of fatal injury!
If the electrical connection is not made proper-
ly, there is a risk of fatal injury from an electric
shock.
The electrical connection must be made by an
electrician approved by the local energy supply
company in compliance with the applicable local
regulations.
• The type of power supply (single phase or 3
phase) and its voltage must correspond to the
specifications on the name plate.
• Fuse in the power supply: 16 A, slow blow.
• Earth the system as required by regulations.
• Using a residual current device ≤ 30 mA
• Using a mains disconnection device with an
opening of at least 3 mm
• The pump is ready for connection.
Pump with three-phase current motor (3~400V):
• For the three-phase current connection (DM) the
leads of the free cable end are to be assigned as
follows.
4-leaded connection cable: 4 x 1,0

Wire up the free end of the cable in the switch box
(see the installation and operating instructions of
the switch box).
8. Starting-up
DANGER! Risk of electric shock!
The pump may not be used for draining swim-
ming-pools / garden ponds or similar places
when there are people in the water.
CAUTION! Risk of damage to the pump!
Prior to starting up the pump, the shaft and the
intake pipes should be freed from solid matter
such as rubbish.
8.1 Checking the direction of rotation
(only for three-phase current motors)
NOTE: If the pump is running in the wrong sense,
the flow is significantly reduced.
You must check the direction of rotation of the
pump before you immerse it. An arrow on the top
of the motor housing shows the correct direction
of rotation.

• Hold the pump in your hand.
• Switch the pump on briefly. The pump recoils
in the opposite direction (anticlockwise) to the
motor's direction of rotation.
• If the direction of rotation is incorrect, swap two
phases of the mains connection.
8.2 Adjusting the control level
CAUTION! Risk of damage to the pump!
The mechanical seal must not run dry!
• Dry running reduces the life of motor and
mechanical seal.
• As protection against dry running for the
mechanical seal, the motor is fitted with an oil-
filled separating chamber.
• The water level may not sink below the minimum
pump immersion depth. Set the level control to
the following minimum level: Fig. 2a, 2b
Min 90 mm: Operating mode S3: see Technical
data.
Min 250 mm: Operating mode S1: see Technical
data.
• When filling the shaft or powering the pump into
the pit, make sure the float switch can move
freely.
• Switch on the pump.
9. Maintenance
Maintenance and repair work should only be
carried out by qualified personnel!
WARNING! Risk of infection!
In order to avoid any risk of infection, main-
tenance work should only be carried out using
appropriate protective clothing (protective
gloves).
WARNING! Risk of electric shock!
Potential dangers caused by electrical energy
must be excluded.
• The pump must be switched off for all main-
tenance and repair work and secured against
unauthorised operation.
• In principle, damage to the connecting cable
should only be repaired by a qualified electri-
cian.
• Change the oil in the mechanical seal chamber
once a year.
• Unscrew Oil drain plug with seal (Fig. 3, pos. A).
• Lay the pump on its side until oil flows out (catch
it in a suitable receptacle and take it for proper
disposal).
NOTE: When you change the oil, the old oil and
water have to be disposed of as hazardous waste.
The oil is not biodegradable.
• Fill the pump with new oil (see Technical data).
• Screw in the oil drain plug and seal ring.
