Electrical Connection; Cleaning, Storage And Maintenance - Scheppach SWP750 Original Instruction Manual

Check the function of the float switch
• The float switch (3) is to be set such that immedi-
ate start-up is possible. In the case of stationary in-
stallation, the function of the float switch (3) must be
checked regularly (at least every three months).
• The on or off switching point of the float switch (3)
can be adjusted by changing the position of the float
switch (3) in the float switch grid (10). Please check
the following points before commissioning.
• The float switch (3) must be positioned in such a
way that the switching point height "On" and the
switching point height "Off" can be reached easily
and with little effort.
• Check this by placing the pump in a container filled
with water and carefully lifting the float switch (3) by
hand and then lowering it again. In doing so, you
can see whether the pump switches on or off. Al-
so make sure that the distance between the float
switch head and the float switch grid (10) is not too
small. If the distance is too small, proper functioning
is not guaranteed.
• When adjusting, make sure that the float switch
(3) does not touch the ground before the pump is
switched off. Attention! Danger of dry-running
and damage to the device.

10. Electrical connection

The electrical motor installed is connected and ready
for operation. The connection complies with the appli-
cable VDE and DIN provisions.
The customer's mains connection as well as the ex-
tension cable used must also comply with these reg-
ulations.
Damaged electrical connection cable
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Pressure points, where connection cables are
passed through windows or doors.
• Kinks where the connection cable has been improp-
erly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the wall
outlet.
• Cracks due to the insulation ageing.
24 | GB
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Ensure that the connection cables are dis-
connected from electrical power when checking for
damage.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables with the designation H05RN-F.
The printing of the type designation on the connection
cable is mandatory.
Connection type Y
If it is necessary to replace the mains connection ca-
ble, this must be done by the manufacturer or their
representative to avoid safety hazards.

11. Cleaning, storage and maintenance

Cleaning
Attention!
Disconnect the mains plug before carrying out any
cleaning work.
General cleaning tasks
• Non-stationary installed devices: Clean the pump
with clean water after each use.
• Stationary installed devices: Check the function of
the float switch (3) regularly (at least every three
months).
• Remove lint and fibrous particles that may have be-
come trapped in the pump housing with a water jet.
• Regularly remove sludge from the base plate (every
3 months at the latest) and clean the shaft walls.
• Clean the float switch (3) of deposits with clean water.
• If you have not used the pump for a longer period of
time, the pump must be cleaned thoroughly after the
last use and before its next use. Otherwise, start-up
problems may occur due to deposits and residues.
Cleaning the impeller wheel (Fig. 2)
If the impeller wheel is dirty or blocked, you can clean
it via the pump connection outlet (8) or by removing the
floor plate (9):
1. Screw the angled pump connection adapter (6) off
the pump connection outlet (8).
2. Remove the screws at the bottom of the pump
housing and take off the floor plate (9).
3. Clean the impeller wheel with clear water.
4. The re-assembly takes place in reverse order.
