Installation, Operation and Maintenance APP Pumps (APP 0.6-1.0)
Table 1: Check points when assembling and commissioning system
Check points
CP1 Ensure that the environmental conditions are safe.
CP2 Minimum and maximum start-up temperature for fluid and
pump.
CP3 Filtration condition (10µm absolute (ß10 = 5000)
CP4 Power supply for electric motor and VFD.
CP5 Safety circuit / breaker must be sized for the motor and
environment (corrosion and humidity)
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).
CP8 Check the factory settings of the safety/relief valves or
pressure relief valves (8 & 9).
CP9 Check the settings of the pressure transmitter/switch (3) set
at min. inlet pressure.
CP10 Check that all pressure indicators (PI) are selected to be able
to measure the system pressure range.
CP11 Check coupling distance ( air gab – movement of the spider )
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.
