2.1 General information
Dangers that can arise from not following the
instructions .
When the pump or pump unit is managed by
untrained personnel, there is a danger of:
•
Death or fatal injuries
•
Costly damages and claims
Electrical
hazard
All electrical installation work must only be
carried out by authorized personnel in
accordance with EN60204-1 and/or local
regulations .
It is recommended to install a lockable circuit
breaker to avoid inadvertent starting and/or
electrical hazard . The lockable circuit breaker
must be used during installation, operation and
maintenance .
It is recommended to place a local safety switch
nearby the pump, enabling service personnel to
cut power from the electric motor .
Protect the motor and other electrical equip-
ment from overloads with suitable equipment .
In case the pump delivered is ATEX certified, the
additional ATEX instruction must also be read .
!
Protective
garments
must be worn
Always wear suitable safety clothing when
handling the pump .
When working near the pump system, safety
shoes, safety glasses, hearing protection and
safety helmet must always be worn .
Under certain operational conditions the surface
of the pump can be above 60°C / 140°F . Under
these conditions the pump must be labelled with
a “Danger Hot” sign .
When using an electric motor, the motor must
always be supplied with adequate cooling
ventilation .
When using an electric motor together with a
VFD, the motor must be designed for operation
with a VFD .
VFD operation may increase the temperature
inside the electric motor if the motor is not
designed for VFD operation . This can damage
the motor and cause unintended breakdown .
Before start-up, the settings for all protective
devices, such as sensors/switches and safety
valves must be verified and free flow from safety
valves must be ensured .
All pipe and hose connections must be stress-
free mounted, securely fastened to the pump
and well supported . Improper installation will or
can result in personal injury and/or damage to
the pump .
Use of this manual does not relieve operation
and maintenance personnel of the responsibil-
ity of applying good judgment when operating
and maintaining the pump and its compo-
nents.
