The unit must be anchored to the floor for longer operating
times with this type of installation. This prevents vibrations as
well as guaranteeing quiet and low-wearing running.
1 Fix the discharge hose to the hose connection on the dis-
charge port.
Alternatively, a Storz fixed coupling and a Storz hose cou-
pling can be fitted to the discharge hose.
With the SCA/SVO..., a pipe bend must be fitted for a
vertical discharge port. The discharge hose can be
fixed to this with a hose clamp or a Storz coupling.
2 Lay the power supply cable so that it cannot be damaged.
3 Position the product in the operating area. If necessary,
secure the load-carrying equipment to the carrying handle, lift
the product and set it down at the intended operating posi-
tion (pit, shaft).
4 Check that the product is upright and standing on a firm
base. Do not let it subside.
5 Have an electrician connect the product to the mains power
supply and check the direction of rotation in accordance with
the chapter entitled "Start-up".
6 Lay the discharge hose so that it cannot be damaged.
Secure at a suitable place as necessary (e.g. drain).
Danger due to discharge hose being pulled
off.
Injuries may result from the discharge hose
being pulled or knocked off accidentally. The
discharge hose must be secured appropri-
ately. Avoid kinks in the discharge hose.
Beware of burns
The housing parts can heat up to well above
40°C. There is a danger of burns. After
switching off, let the product cool down to
ambient temperature.
Beware of damaging threads!
Threads can be damaged by excessive
screwing and different flanges.
Therefore, please note:
Only use M16 thread bolts with a maximum
length of 12...16 mm.

SVO 205) / 25 Nm (SCA/SVO 206).
Only use flanges confirming to DIN 2576 form
B (without sealing strip).
This requirement is fulfilled by the use of
Salmson accessories.

Dry-run protection
Make sure that no air enters the hydraulic housing. The prod-
uct must therefore always be submerged in the pumped liquid
up to the top edge of the pump housing. For optimum reliabil-
ity, we recommend installing a dry-run protection system.
Correct running is ensured by float switches or electrodes. The
float switch or electrode is fixed in the shaft and switches off the
machine when the water level falls below the minimum cover-
age level. If dry-run protection is only put into effect with one
float or electrode, the unit may turn on and off constantly if fill-
ing levels fluctuate strongly! This can result in the maximum
number of motor start-ups (switching cycles) being exceeded.

5.5.1 Corrective measures for avoiding excessive
switching cycles
Manual reset - The motor is switched off when the water level
falls below the minimum coverage level and switched back on
when a sufficient water level is reached.
Separate reactivation point - A second switching point (addi-
tional float or electrode) is used to obtain a sufficient difference
between the activation and deactivation points. This prevents
constant switching. This function can be put into effect with a
level control relay.
Risk of fatal injury due to explosion!
Switching functions may cause explosions in
explosion hazard areas. Therefore, sensors
(e.g. electrodes) approved for use in explo-
sive areas must be used for monitoring lev-
els. These sensors are actuated via an Ex
relay. Please consult the responsible quali-
fied electrician about this.

Electrical connection
Risk of fatal injury due to electrical current!
There is a risk of fatal electric shocks caused
by improper electrical connections. Electri-
cal connections may only be carried out by a
qualified electrician who is approved by the
local power supplier, in accordance with
locally applicable regulations.
- Mains current and voltage must correspond to the details on
the type plate.
- Connect the power supply cable in accordance with the
applicable standards and regulations and according to the
wire assignment.
- Any available monitoring equipment, e.g. for the motor tem-
perature, must be connected and tested to ensure that it is
working properly.
- For three-phase current motors, a clockwise rotating field
must be available.
- Ground the product properly.
Products that are permanently installed must be grounded in
compliance with nationally applicable standards. If a sepa-
rate grounding conductor is available, it must be connected
to the marked hole or grounding terminal (;) using a suitable
screw, nut, toothed washer and flat washer. The cross sec-
tion of the cable for the grounding conductor connection
must correspond to the local regulations.
- A motor protection switch must be used. We recommend
using an earth leakage circuit breaker (RCD)
- Switching devices are to be purchased as accessories.
