
After storage longer than one year the oil of motor and, if necessary the gear have to be changed.
This is also necessary if the product never had run (natural deterioration of mineral oil).
Before start-up, the filling levels (oil, cooling fluid etc.) of the individual products should be checked and
topped up if required. Please refer to the machine data sheet for specifications on filling. Damaged
coatings should be repaired immediately. Only a coating that is completely intact fulfills the criteria for
intended usage!
If these rules are observed, your product can be stored for a longer period. Please remember that elastomer parts
and coatings become brittle naturally. If the product is to be stored for longer than 6 months, we recommend
checking these parts and replacing them as necessary. Please consult the manufacturer.

4.4. Returning to the supplier

Products which are delivered to the plant must be clean and correctly packaged. In this context, clean means that
impurities have been removed and decontaminated if it has been used with materials which are hazardous to
health. The packaging must protect the product against damage. Please contact the manufacturer before
returning!

5. Installation and Start-Up

5.1 General

The following points must be noted to prevent damages in the pump during installation and commissioning:

The installation work must be carried out by qualified personnel in compliance with the safety
regulations.

The pump must be checked for possible damages prior to installation.

The minimum submersion in water must be considered for level control.

Air pockets in the pump casing and in pipes must be avoided (by means of appropriate venting
facilities or slight tilting of the pump).

Protect the pump from frost.

The mechanical room must be designed for the respective machinery. This includes also that a
lifting device for assembly/disassembly can be installed, with which the installation site of the pump
can be reached without danger.

The power lines of the pump must run in a way that hazard-free operation and easy
assembly/disassembly is possible.

The power line must be fixed professionally in the mechanical room so that loose hanging of the
leads is prevented. Depending on the length and weight of the leads a cable holder must be fitted
every two to three metres.

5.2 Installation

Danger of falls!
When mounting the pump and its accessories work is carried out directly at the edge of the basin!
Carelessness or wrong footwear can lead to falls. There is danger to life!
Take all safety measures to prevent this.
Fix the pressure pipe or the hose on the pressure branch of the pump and lay the pressure pipe. When using a
hose connection or pipe connection with thread the hose connector at the branch of the pump can be cut off. The
pressure pipe should have a minimum diameter of 3/4" to ensure optimal conveyor performance. Additionally, a
swing non-return flap can be mounted in the pressure pipe to prevent backward running of the water when the
pump is switched off. The pressure pipe must be mounted without tension.
When using the hose it must be ensured that this is laid our without bends. When using accessories, such as a
quick coupling, or similar, it has to be ensured that these are sealed with teflon tape, since leakage reduces the
conveyor performance of the pump.
Since the pump can work at very low extraction heights, the pump must be set up on a firm, non-flexible
floor. If the pump is standing on a flexible floor (e.g. in a plastic tank) the pump can attach itself by suction to the
floor and cannot transfer the fluid. Fix the pump on the handhold with a rope and chain and lower down into the
medium. The pump must be securely set up on the floor; open the valves if necessary. The sensor switch must be
placed on the floor with the electrodes on the underside. It is important to ensure that the lower edge of the
sensor switch housing is in direct contact with the floor to ensure proper function. The run time of the pump is 4
minutes.
