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 Data sheet or Instruction,
appendices 1 and 2 .
CP3
Filtration condition (10µm absolute (ß10 = 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, appendix 1 .
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
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 manufacturer’s recom-
mendations . (see also Data sheet for Hose
and hose fittings and Instruction for
Assembling Hose kit - both available on
www .ro-solutions .danfoss .com) .
•
Misalignment of the hard pipes may place
stress on the pump port connection 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)
Mount the safety circuit breaker, turn the circuit
off and lock it in the off position .
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 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 connections and maybe check valve(s) .
Mount and tighten as specified .
