Installation Conditions
6.3.1
Installation Conditions for Motor Pump Unit
Before assembling the motor and the pump, ensure the following:
●
Use tools, supplies, measuring and test equipment.
●
Check all components for visible damage. Damaged components may
not be mounted.
●
Ensure that all dimensions and tolerances on the machine side are suit‐
ed for the component attachment.
●
Inspect all components, mounting surfaces and threads to ensure they
are clean.
●
Make sure that the assembly can be carried out in a dry and dust-free
environment.
●
Ensure that the motor-pump unit and all other used parts are clean,
when they are mounted.
A polluted hydraulic fluid can considerably influence the lifetime of
the drive unit.
●
Ensure that the temperature of the motor-pump unit is according to the
environmental temperature of the installation site. Allow sufficient time to
the components to adjust the temperature conditions.
●
Before assembling the motor-pump unit, remove fluids that might have
been filled in for storing the pump.
●
Please observe that the motor-pump unit is not suited for mounting the
pump under oil.
●
Ensure that the minimum distance between fan screen and machine is
kept to suction/blow the air.
