1. In General
1.1 Safety Rules
Pump operation without a safety valve as well
as any excess in temperature or speed limits
automatically voids the warranty.
The safety valve must be regulated in
accordance with the guidelines for liquid
spraying units so that the admissible operating
pressure can not be exceeded by more than
10%.
1.2 Fields of Use
The pump is suitable for conveying fresh,
clean water (50 μm filtered) with a maximum
temperature of 140 °F (60 °C).
Figures given for maximum pressure and
maximum speed (rpm) apply to interval
operation. When the pump is used in continual
operation and/or with water warmer than 100 °F
(40°C), these values must be reduced by 10%.
2. Safety
This Operation Manual gives basic instructions
which are to be observed during installation,
operation and maintenance of the pump. It is
therefore imperative that this manual be read
by the responsible personnel/operator prior to
assembly and commissioning. It is always to be
kept available at the installation site.
It is not only the general safety instructions
contained under this main heading safety
that are to be observed but also the specific
information provided under the other main
headings.
2.1 Identification of Safety
Instructions in the Operating
Manual
Safety instructions given in this manual,
noncompliance with which would affect safety,
are identified by the following symbol:
see DIN 4844 - W9
or where electrical safety is involved, with
see DIN 4844 - W8
Safety measures which can cause damage to
the machine if not adhered to, are marked
Important!
It is imperative that signs affixed to the
machine, e.g.
•
arrow indicating the direction of rotation
•
symbols indicating fluid connections
be observed and kept legible.
2.2 Qualification and Training of
Operating Personnel
The personnel responsible for operation,
maintenance, inspection and assembly
must be adequately qualified. Scope
of responsibility and supervision of the
personnel must be exactly defined by the
plant operator. If the staff does not have the
necessary knowledge, they must be trained
and instructed, which may be performed
by the machine manufacturer or supplier
on behalf of the plant operator. Moreover,
the plant operator is to make sure that the
contents of the operating manual are fully
understood by the personnel.
2.3 Hazards in the Event of
Noncompliance with the Safety
Instructions
Noncompliance with the safety instructions
may produce a risk to the personnel as well
as to the environment and the machine and
result in a loss of any right to claim damages.
For example, noncompliance may lead to the
following hazards:
•
Failure of important functions of the
machine/plant
•
Failure of specified procedures of
maintenance and repair
•
Exposure of people to electrical,
mechanical and chemical hazards
•
Endangering the environment owing to
hazardous substances being released.
