1. General Information

1.1. Preface

All safety requirements and specific manufacturer's
requirements must be fulfilled before the product
is put into operation. This operating and maintenance
manual supplements any existing national regulations on
industrial safety and accident prevention. This manual must
also be accessible to personnel at all times and also be
made available where the product is used.

1.2. Spare parts, add-ons and conversions

Only original spare parts as supplied by the manufacturer
may be used for repairs, replacements, add-ons and
conversions. Only these parts guarantee a long working life
and the highest level of safety. These parts have been
specially designed for our products. Self-made add-ons
and conversions or the use of non-original spare parts can
seriously damage the product and/or injure personnel.

1.3. Maintenance

The prescribed maintenance and inspection work should
be carried out regularly. This work may only be carried out
by qualified, trained and authorized personnel. The
maintenance and inspection log supplied must be
properly updated. This enables you to monitor the status
of inspections and maintenance work. Quick repairs not
listed in this operation and maintenance manual and all
types of repair work may only be performed by the
manufacturer and its authorized service centres.

1.4. Damage to the product

Damage as well as malfunctions that endanger safety must
be eliminated immediately by authorized personnel. The
product should only be operated if it is in proper working
order. During the agreed warranty period, the product may
only be repaired by the manufacturer or an authorized
service workshop! The manufacturer reserves the right to
recall the damaged product to the factory for inspection!

1.5. Technical terms

Various technical terms are used in this operating and
maintenance manual.
Dry run
The product is running at full speed, however, there is no
liquid to be pumped. A dry run is to be strictly avoided. If
necessary, a safety device must be installed.
"wet" installation type
This installation type requires the product to be immersed
in the pumped fluid. It is completely surrounded by the
pumped fluid. Please observe the values for the maximum
submersion depth and the minimum water coverage.
"dry" installation type
In this installation type, the product is installed dry, i.e. the
pumped fluid is delivered to and discharged via a pipeline
system. The product is not immersed in the pumped fluid.
Please note that the surfaces of the product become very
hot!
"transportable" installation type
With this installation type the product is equipped with a
pedestal. It can be installed and operated at any location.
Please observe the values for the maximum submersion
depth and the minimum water coverage, and remember
that the surfaces of the product become very hot.
"S1" operating mode (continuous operation)
At the rated load, a constant temperature is reached that
does not increase even in prolonged operation. The
operating equipment can operate uninterruptedly at the
rated load without exceeding the maximum permissible
temperature.
"S2" operating mode (short-term operation)
The operating time is specified in minutes, for example, S2-
20. That means, that the machine can work 20 minutes and
should pauses after it, as long as the machine is cooled
down to 2K over medium temperature.
Operating mode "S3" (intermittent operation):
For these operating modes, after the abbreviation, the duty
cycle is displayed as well as the cycle duration if it deviates
from 10 minutes. Example S3 30% means, that the
machine can work 3 minutes and afterwards should pauses
7 minutes.
"Sip operation"
Siphoning operation is similar to dry running. The product
operates at full speed, but only small amounts of liquid are
pumped.
Sip operation is only possible with certain types; see
the "Product description" chapter.
Dry-run protection
The dry-run protection is designed to automatically shut
down the product if the water level falls below the minimum
water coverage value of the product. This is made possible
by installing a float switch.
Level control
The level control is designed to switch the product on or off
depending on the filling level. This is made possible by
installing a float switch.

2. Safety

This chapter lists all the generally applicable safety
instructions and technical information. Furthermore, every
other chapter contains specific safety instructions and
technical information. All instructions and information must
be observed and followed during the various phases of the
product's lifecycle (installation, operation, maintenance,
transport etc.). The operator is responsible for ensuring that
personnel follow these instructions and guidelines.

2.1. Instructions and safety information

This manual uses instructions and safety information for
preventing injury and damage to property.
To make this clear for the personnel, the instructions and
safety information are distinguished as follows:
Each safety instruction begins with one of the following
signal words:
Danger: Serious or fatal injuries can occur!
Warning: Serious injuries can occur!
Caution: Injuries can occur!
Caution (Instruction without symbol): Serious damage
to property can occur, including irreparable damage!
Safety instructions begin with a signal word and description
of the hazard, followed by the hazard source and potential
consequences, and end with information on preventing it.
