 Provide mufflers on inlet and discharge side
with sealing plugs.
8.2 Storage
conditions
To prevent standstill damage during storage, the
environment must provide the following
conditions:
 dry,
 dust-free,
 low-vibration (effective value of vibration speed
v
eff
≤ 2.8 mm/s).
 Ambient temperature: max. +40°C [+104°F].
CAUTION
Danger of overheating due to high
temperature!
When storing in an environment with a
temperature of over +40°C [+104°F] the winding
may be damaged and the grease change
interval may be shortened.
Lubrication of rolling bearings after longer
storage:
The new pump-motor unit may at first be stored
following delivery.
If the time from deliver to commissioning exceeds
the following periods, the lubrication of the rolling
bearings must be renewed:
 Under advantageous storage conditions
(as specified above): 4 years.
 Under disadvantageous storage conditions
(e.g. high humidity, salty air, sandy or dusty
air): 2 years.
In these cases open rolling bearings must be
relubricated and closed rolling bearings must be
completely replaced. In this case be sure to
inquire with the Service Department. In particular,
exact information with regard to the procedure
and grease type are required.
 WARNING
Improper use of the unit can result in
serious or even fatal injuries!
All maintenance work on the pump-motor unit
must always be performed by the Service
Department!
Maintenance work on the pump-motor unit may
only be conducted by the operator itself when
the related maintenance manual on hand!
Inquire with the Service Department!
Commissioning after longer standstill:
Before recommissioning after a longer standstill,
measure the insulation resistance of the drive
motor. With values ≤ 1 kΩ per volt of nominal
voltage, the winding must be dried.
