Danger of rusting due to collection of condensed water in drive motor area!

On drive motors with closed condensed water openings: Remove closures occasionally to allow any water which has collected to drain off.

CAUTION

Danger of bearing damage!

Avoid mechanical shocks during operation and shut-down.

Prior to shut-down or longer standstill, proceed as follows:

 Switch off the pump-motor unit.

 Close shut-off device in inlet and pressure line

if installed.

 Disconnect pump-motor unit from power

supply.

 Release pressure.

When doing so, open pipes/hoses slowly and carefully so that the vacuum or gauge pressure in the pump-motor unit can be released.

 Remove pipes/hoses.

 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 (V

 Ambient temperature:

min. -30°C [-22°F] max. 40°C [+104°F].

≤ 2.8 mm/s [0.11"/sec]).

eff

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 is too dry.
