could result in minor or moderate personal injury.
WARNING
Installing, commissioning, operating and servicing of
refrigerant pumps can be associated with risks for life
and health of the persons involved, damage to the
pump and damage to other property. Therefore these
tasks must only be carried out by persons having the
competencies required by national rules and
regulations for refrigeration systems or similar
systems.
WARNING
The tasks of designing, installing, commissioning,
operating and servicing a refrigeration system may
be individually covered by national and international
rules and regulations. Similar rules and regulations
may exist for other types of systems using refrigerant
pumps. These rules and regulations must always be
observed.
WARNING
The pump must be connected to an external power
supply located close to the pump and to a motor-
protective circuit breaker or a CUE frequency
converter.
It must be possible to lock the power supply in
position OFF (isolated). Type and requirement are as
specified in National Electrical Code and all local
codes.
CAUTION
Only pumps in perfect technical condition must be
operated. If the pump has visible defects, or if
internal defects are suspected, the pump must not be
operated. Follow the guidelines for maintenance and
service to inspect the pump for defects, or contact
your local Grundfos company.
CAUTION
A refrigeration system is a pressurized system
containing refrigerants which may be flammable and/
or toxic. In addition, components and parts of the
system may have extreme temperature - both high
and low.
WARNING
Persons with pacemaker or other magnet-sensitive
medical devices must not handle this pump. They
must keep a distance of at least 3 ft. from the pump,
as there is a risk of influence from the magnetic fields
of the pump.
Credit cards, computers, watches and other magnet-
sensitive objects must not be kept close to the pump.
WARNING
The pump contains powerful magnets that may pose
a risk of personal injury when servicing the pump.
The pump must therefore only be dismantled and
assembled by authorized persons.
