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
fl
uid 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
fl
uid 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 di
ff
erent equipment
(connections, pipes, tubes, check and safety/relief
valves, etc.)
t
The hard piping and
fl
exible 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
fi
ttings and Instruction for
Assembling Hose kit - both available on
www.ro-solutions.danfoss.com).
t
Misalignment of the hard pipes may place
stress on the pump port connection and may
damage the pump.
t
Prevent excessive external pipe load.
t
Do not connect piping by applying external
force (use of wrenches, crane, etc.) Piping
must be aligned without residual stress.
t
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
o
ff
and lock it in the o
ff
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 speci
fi
ed.
