Check points Comment OK ?
CP1
Ensure that the environmental conditions are safe . See Arrival inspection,
transportation, handling,
lifting and storage, chapter 4 .
CP2
Minimum and maximum start-up temperature for fluid and
pump .
See Instruction, appendix 2 .
CP3 Filtration condition (10 µm absolute [ß
10
≥ 5000]) See Danfoss requirements in
Data sheet and Instruction,
appendices 1 and 2
CP4 Power supply for electric motor and VFD . See Data sheet for the used
motor and VFD .
CP5
Safety circuit / breaker must be sized for the motor and
environment (corrosion and humidity)
See Data sheet for the used
safety circuit .
CP6 Bolts and screws must conform to environmental conditions
as well as fluid and torque requirements .
CP7
Instrumentation, pressure switch should be designed to
conform to the environment (corrosion and humidity) .
See Data sheet for the used
equipment .
CP8 Check the factory settings of the safety/relief valves or
pressure relief valves (8 & 9) .
See Data sheets for the used
valves .
CP9
Check the settings of the pressure transmitter/switch (3) set
at min . inlet pressure .
See Data sheet or Instruction,
appendices 1 and 2 .
CP10 Check that all pressure indicators (PI) are selected to be able
to measure the system pressure range .
Scaling should at least be 1 bar
or more precise .
CP11
Check coupling distance ( air gab – movement of the spider ) 3 – 5 mm, see Instruction,
appendix 2 .
CP12 Check correct connections on the pump ( in & outlet)
CP13 Check piping for possible air gaps .
5.7 Lifting and positioning
Lift the pump unit onto base (Remember
vibration dampers, if needed) . Fasten the motor
to the base .
See also chapter 4, Arrival inspection, transporta-
tion, handling, lifting and storage .
5.8 Mount the different equipment
(connections, pipes, tubes, check and safety/relief
valves, etc.)
• The hard piping and flexible hoses used,
must be of proper design and must be
installed in accordance with the manufactur-
er’s recommendations .
• Misalignment of the hard pipes may give
unintended stress on the pump port
connections and may damage the pump .
• Prevent excessive external pipe load .
• Do not connect piping by applying external
force (use of wrenches, crane, etc .) Piping
must be aligned without residual stress .
• Do not mount expansion joints so that their
force applies internal pressure on the pump
connections .
5.9 Electrics
All electrical installation work must be carried
out by authorized personnel in accordance with
EN60204-1 and/or local regulations . (see also
Safety, chapter 2)
Turn off the safety circuit breaker and lock it .
Mount the power cable on the electric motor .
If a VFD is used, adjust the protective motor
switch/VFD to the current limits found on the
name plate of the electric motor .
5.10 Instrumentation
The pressure switch/sensor should be mounted
as close to the pump as possible . It is recom-
mended to test the pressure/sensor switch via an
instrumentation manifold .
Mount the pressure switch/sensors according to
the manufacturer’s instructions .
5.11 Connections
Mount and tighten connections and check
valve(s) as specified .
