due to heavy rain. Run the pressure line directly to the next
collecting runoff. Check all joints and connections again for
tightness.
A freezing of the pressure line must be prevented. It is
advisable to insulate the entire pressure line sufficiently.
According to DIN, all connected sanitation facilities must be
located in the same room as the system.

5.3. Electrics

Risk of electrocution!
Improper use of electricity can be fatal! All pumps with
free cable ends must be connected by a qualified
electrician.
A professional inspection prior to initial
operation must ensure that the required electrical
protection measures exist. Grounding, zeroing,
isolating transformer, fault current or earth leakage
circuit breaker must comply with the regulations of the
responsible power station.
The voltage specified in the technical data must
correspond with the local power supply.
Ensure that the electrical plug connections are
located in a flood-proof area and are protected from
moisture. Power cords and plugs must be checked for
damage before use.
The end of the connector cable must not be
submerged in water, otherwise water can get into the
motor terminal compartment.
The electrical connection must be made in accordance with
the local regulations. The supply voltage and frequency are
indicated on the nameplate of the pump and the switching
device. The voltage tolerance must be between 6% to -
10% of the supply voltage. It is important to ensure that the
data provided on the nameplate corresponds with the
existing power supply. The lifting systems require no further
motor protection. The device is connected to the mains via
the shockproof plug.

5.4. Initial operation

Never allow the pump to run dry for a
prolonged period of time (risk of overheating).
Plug the power cord into a grounded outlet; the lifting
system is now ready for use. The pump starts working as
soon as the water level has reached the starting level in the
collection container. Once the water level reaches the stop
level, the pump switches off.

6. Maintenance

6.1. General

The entire system must be inspected and maintained at
regular intervals.
The following points must be noted:

The operating instructions must be available
to the maintenance personnel and must be
followed.
measures listed here must be carried out.

All maintenance work, inspection work and
cleaning work on the machinery and the
system must be carried out with due
diligence, at a safe working place and by
trained qualified personnel. The required
protective gear must be worn. The machinery
must be disconnected from the power supply
for all work. Unintentional start must be
prevented.

Electric works on the machinery and the
system must be carried out by a specialist.

If easily inflammable dissolvers and cleaning
materials are used, open fire, open light and
smoking are prohibited.

Ensure that the required tools and materials
are readily available. Tidiness and cleanness
ensure safe and proper work on the
machinery. Remove used cleaning materials
and tools from the machinery after the work
has been carried out. Keep all materials and
tools in a dedicated place.
A test run or function test of the machinery must only
be carried out according to the general operating
conditions!

6.2. Maintenance schedule

Every six months:

Visual inspection of the power supply leads

Clean the collecting tank

6.3. Maintenance work

Visual inspection of the power supply leads
The power inlet leads must be inspected for bubbles,
cracks, scratches, scour marks and/or crushing zones. If
damages are detected, the damaged power inlet lead must
be replaced immediately.
The leads may only be replaced by the manufacturer or
an authorised/certified
machinery must only be started after appropriate repair
of the damage!
Visual inspection of the cable holders (biners) and the
wiring (traction cable)
If the machine is used in basins/shafts the hoisting
wires/cable holders (biners) and the wiring are subject to
constant wear and tear. Regular inspections are required to
prevent a complete wear and tear of the hoisting
wires/cable holders (biners) and/or wiring and a complete
damage to the power cable.
The hoisting wires/cable holders (biners) and the
wiring must be replaced immediately if there are slight
signs of tear and wear!
