• The float switch (8) 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 (8) 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 clip (7) is not too
small. If the distance is too small, proper functioning
is not guaranteed.
• When adjusting, make sure that the float switch (8)
does not touch the floor before the pump is switched
off. Attention! Danger of dry-running and dam-
age to the product.
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 exten-
sion cable used must also comply with these regulations.
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.
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 rep-
resentative 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 products: Clean the pump
with clean water after each use.
• Stationary installed products: Check the function of the
float switch (8) 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 (8) 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
If the impeller is dirty or blocked, you can clean it via
the pump pressure connection (5) or by unscrewing the
suction strainer (6):
1.
Unscrew the pump connection bend (4) at the
pressure connection of the pump (3).
2.
Remove the screws on the underside of the pump
housing and take off the suction strainer (6).
3.
Clean the impeller wheel with clear water.
4.
The re-assembly takes place in reverse order.
Storage
Store the product and its accessories in a dark, dry and
frost-free place that is inaccessible to children. The op-
timum storage temperature lies between 5 and 30 ˚C.
Store the product in its original packaging.
Cover the product to protect it from dust or moisture.
Store the operating manual with the product.
Maintenance
The pump is largely maintenance-free. However, we
recommend regular inspections and care for a long
service life.
