7.1.2 Portable wet installation
For portable wet installation with hose connection, 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 properly, there
is a risk of fatal injury from an electric shock.
The electrical connection must be made by an electri-
cian 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 volt-
age 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 motor (3~400V):
For the three-phase connection, connect the wires at the free
end of the cable as follows:
4-wire connection cable: 4x1,0 mm²
Wire
Terminal

PE
Wire up the free end of the cable in the switch box (see the
installation and operating instructions of the switch box).
8. COMMISSIONING
DANGER! Beware of electric shock!
The pump may not be used to empty swimming pools,
garden ponds or similar if there are people in the water.
CAUTION! Danger of material damage!
Before installation, clean the pond and the supply pipes
from all solid materials such as rubble.
8.1 Checking the direction of rotation (three-phase motors
only)
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 level control
CAUTION! Danger of material damage!
Do not allow the mechanical seal to run dry.
Dry running shortens the life of the motor and the
mechanical seal. If the mechanical seal is damaged,
small amounts of oil may escape into the pumped fluid.
•The water level may not sink below the minimum pump immer-
sion 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 (Salmson FVO 204...F) can move freely.
•Switch on the pump.
9. MAINTENANCE
Maintenance and repairs may only be carried out by qualified
experts!
WARNING! Beware of infection!
Wear suitable protective clothing (safety gloves) for
maintenance in order to prevent any risk of infection.
Danger! Beware of fatal injury!
When working on electrical equipment, there is a risk of
a fatal shock.
•For all maintenance and repair work on the pump, it
must be electrically isolated and unauthorised switch-
on must be prevented.
•Any damage to the connection cable must always be
repaired by a properly qualified electrician.
•Change the oil in the mechanical seal chamber once a year.
– Unscrew the oil drain plug with seal ring (Fig. 3, Pos. A).
– Lay the pump on its side until oil flows out (catch it in a suit-
able 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.
