2.1 General information
Dangers that can arise from not following the
instructions:
When the pump or pump system is managed by
untrained personal, there is a danger of:
tDeath or fatal injuries
tCostly 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.
Install a lockable circuit breaker to avoid
inadvertent starting.
Protect the motor and other electrical equip-
ment from overloads with suitable equipment.
!
Protective
garments
must be worn
It is recommended to place a local safety switch
near by the pump, enabling service personal to
cut power for the electric motor. This prevents
unintentionally starting the unit during servicing.
Always wear suitable safety clothing when
handling the pump.
When working near the pump system, safety
proof boot/shoes, safety glasses, ear 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 VFD. VFD operation may increase the
temperature inside the electric motor if the
motor is not designed for VFD operation.
Before start-up, the settings for all protective
devices, for example, 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 pumps
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 normal good judgment in the
operation and care of the pump and its
components.
2.2 Preferred system design
Danfoss recommends building systems with a
high degree of safety. See Danfoss preferred
system design and PI&D in Data sheet and
Instruction which are found in appendix 1 (Data
sheet) and 2 (APP pump instruction).
It is always the system builders responsibility that
the system design does not cause any kind of
hazard and is adapted to local regulations and
standards.
Proper installation, care of start up and shut-
down devices and over-pressure protection
equipment is essential.
2.3 Commissioning and servicing the unit
It is recommended that commissioning and
servicing are carried out by a minimum of two
people, where one is acting as a supervisor.
2.4 Adhere to the following important
points
t

important to read and understand this user
manual.
t Do not try to lift the pump unit manually;
most of the pumps weight more than
20 kilos, see specic weight for the pump
in the Data sheet, which is found in
appendix 1.
t Do not run the pump if it is completely dry
and not bleeded.
t Do not mount the pump without the bell
