High-pressure submersible pumps w ith retrospectively installed HPS 2
Connect the pump to the mains supply. Put the On/Off switch at the pump switching device into the "On" position.
The green diode on the HPS 2 lights up. When first put into operation, the pump switches on for a few seconds
(the amber diode is lit), so that the pressure required for automatic operation can be built up in the pressure line. If
the amber diode is extinguished and the necessary pressure has not been built up, the red diode lights up. In this
event, proceed as follows:
With the point of consumption (e.g. water tap) open, press the "Reset" button and hold it down until the red diode
is extinguished. Release the button and close the point of consumption. The pressure in the system is now built
up. The pump switches off and the amber diode is extinguished when the necessary pressure has been reached.
5.9.1 After powering up
The rated current is momentarily surpassed during the start-up process. After termination of this process, the
work current should no longer exceed the rated current. If the motor does not start right after switch-on, it must be
switched off immediately. Before further switch-on, the switch pauses must be complied with according to the
technical data. In the event of further interference, the machine must be switched off immediately. A further
switch-on process may only be started after recovery of the fault.
The following points should be checked:

Operating voltage (permitted dev/- 5% of the rated voltage)

Frequency (permitted deviation -2% of the rated frequency)

Power input (permitted deviation between the phases, max. 5%)

Voltage difference between the individuals phases (max.1%)

Switching frequency and pauses (see technical data)

If there is introduction of air in the feed stream, an impact plate must be fitted, if appropriate.

Minimum submersion in water, level control, protection against dry run

Smooth running

Check for leaks and if necessary, follow the required steps according to the Chapter "Maintenance”.
6. Maintenance
6.1 General
The machine and the entire system must be inspected and maintained at regular intervals. The time limit for
maintenance is set by the manufacturer and applies to the general conditions of use. The manufacturer should be
consulted if the system is to be used with corrosive and/or abrasive pumped liquids, as the time limit between
inspections may need to be reduced.
Note the following information:

The operating and maintenance manual must be available to the maintenance personnel and its
instructions followed. Only the repair and maintenance measures listed here may be performed.

All maintenance, inspection and cleaning work on the machine and the system may only be carried
out by trained specialists exercising extreme care in a safe workplace. Proper protective clothing is
to be worn. The machine must be disconnected from the electricity supply before any work is carried
out. There must be no way that it can be inadvertently switched on. Additionally, the appropriate
protective measures as defined by the BGV/GNV should be enforced when working in basins and/or
containers.

Make sure that all fastening devices, ropes and safety devices of the hand winch are in a technically
perfect condition. Work may only commence if the auxiliary hoisting gear has been checked and found to
be in perfect working order. If it is not inspected, danger to personnel may result!

When working with inflammable solvents and cleaning agents, fires, unshielded lighting and
smoking are prohibited.

Ensure that all necessary tools and materials are available. Tidiness and cleanliness guarantee safe
and problem-free operation of the machine. After working on the machine all cleaning materials and
tools should be removed from it. All materials and tools should be stored in an appropriate place.

Operating supplies such as oil and lubricants must be collected in appropriate vessels and properly
disposed of (in accordance with the 75/439/EEC directive and with §§5a, 5b AbfG). Appropriate
protective clothing is to be worn for cleaning and maintenance jobs. This is to be disposed of in
accordance with waste code TA 524 02 and EC Directive 91/689/EEC. Only lubricants expressly
recommended by the manufacturer may be used. Oils and lubricants should not be mixed. Only use
genuine parts made by the manufacturer.
A trial run or functional test of the machine must be performed as instructed in the general operating
conditions.
