Safety information
Classification of the safety information
Knowledge of the User Manual
The User Manual for this unit constitutes an integral part of this Service
Manual. For performing servicing activities it is assumed that the reader
has knowledge of the User Manual, especially procedures for installation,
putting into operation, and handling.
Protection from the risk of electric shock
WARNING! The WARNING! safety indication refers to a risk of personal injury.
CAUTION! The CAUTION! safety indication refers to a risk of damage to property.
ATTENTION! The ATTENTION! safety indication refers to a risk which can cause
equipment to become unserviceable.
IMPORTANT! The IMPORTANT! designation indicates application information and
other particularly important information.
WARNING! The supply voltage must match the voltage specified on the rating
plate. Connect the unit / the equipment cart to a properly installed
grounded outlet. Only use the Erbe power cord or an equivalent power
cord for this purpose. The power cord must bear the national test sym-
bol.
For safety reasons, multiple outlets and extension cords should not be
used. If their use is unavoidable, they also must be provided with proper
grounding.
WARNING! Unplug the power cord from the outlet before exchanging parts of the
unit or cleaning it.
WARNING! Do not plug a wet power cord into the unit or into an outlet.

Electrostatically sensitive components
Liability and warranty
WARNING! Do not touch any unprotected wires or conductive surfaces while the
unit is opened and under voltage.
WARNING! Blown line fuses may only be replaced by a competent technician. Only
replacement fuses of the rating specified on the unit's name plate may
be used. Before resuming operation the unit must be subjected to a
performance test by a competent technician.
CAUTION! This unit contains electrostatically sensitive components. Work at an
anti-static workplace while repairing the unit. Wear a grounding arm-
band while working with electrostatically sensitive components. Hold
the circuit boards by their non-conducting corners. Use an anti-static
container for transporting electrostatically sensitive components and
the circuit boards.
ATTENTION! Adjustments, tests, modifications, maintenance and repair work may
only be performed by Erbe or persons trained by Erbe. If the work is not
performed by trained persons, Erbe accepts no liability and warranty
rights become void.
It is recommended that the technical safety check also be performed by
Erbe or persons trained by Erbe.
ATTENTION! Only use original Erbe spare parts. The manufacturer accepts no liability
and the warranty rights becomes void if original spare parts are not
used.

Description of function
Peristaltic pump principle The EIP 2 (Erbe Irrigation Pump) is a peristaltic pump. This operating prin-
ciple is based on pressing or squeezing a flexible pump hose at one or
more points and on movement of the squeezed point in the desired direc-
tion of liquid flow. For this reason peristaltic pumps are sometimes re-
ferred to as peristaltic squeeze pumps. Movement of the squeezed point is
accomplished with the aid of a pump rotor that has rollers around its pe-
rimeter. Flow is determined by rotor speed (speed of motion of the
squeezed point) and internal cross-section of the hose.
Advantages of peristaltic pumps With peristaltic pumps the medium and the pump do not come into contact
with one another. Therefore peristaltic pumps are particularly suited for
metering a very wide range of media. As opposed to other types of pump
like diaphragm pumps, with peristaltic pumps it is very easy to adapt the
material of the pump hose, or components coming into contact with the
medium, to the product being pumped. A pump hose is selected and used
that is chemically suited for the product being pumped ("milled hose").
