2.1 General information
Dangers that can arise from not following the
instructions:
When the pump or pump system 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 for the electric motor.
Protect the motor and other electrical equip-
ment from overloads with suitable equipment.
In case the pump delivered is ATEX certied, 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 (Variable Frequency Drive), the motor must
be designed for operation with 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 veried and free ow 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
could 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.
