Shut-Down and Longer Standstills

10 Shut-Down and Longer Standstills

10.1 Draining



DANGER

Electrical danger!

Before beginning work on the

unit or system, the following

measures must be carried out:

 Deenergize.

 Secure against being

switched on again.

 Determine whether

deenergized.

 Ground and short-circuit.

 Cover or block off adjacent

energized parts.



WARNING

Danger due to gauge pressure

and vacuum!

Danger due to escaping fluid!

Before beginning work on the

unit or system:

 Interrupt supply of operating

liquid.

 Bleed lines and vacuum

pump/compressor

(depressurize).

 Switch off the pump-motor unit.

 The above safety precautions apply when

working on the unit or system.

 Provide suitable catch containers below the

vacuum pump/compressor housing.

 Open the screw plug (Fig. 7, Pg. 25,

Item 5).

 Allow the liquid to drain out.

 Close the screw plug again,

tightening torque T

t

= 2 ... 3 Nm

[1.48 ... 2.21 ft lbs].

10.2 Preparing for longer standstill

Before a longer standstill (from approx.

4 weeks) or when there is danger of frost,

proceed as follows:

 Drain pump-motor unit as described in

Chapter 10.1, "Draining", Pg. 34.

 Remove the pipe/hose from the intake or

discharge connection.

 Pour ½ l [0.132 gal (US); 0.110 gal (UK)] of

preservative (rust protection oil, e.g.

Mobilarma 247 form Mobil Oil)

into the open intake or discharge

connection.

 Close the intake and discharge connection,

as well as the operating-liquid port and

remount the disconnected pipes/hoses.

 Guide a M6 or M8 bolt (depending on the

type) with a sufficient shank length through

the center opening into the fan guard and

screw into the shaft end on the external fan

side (see Fig. 14, Pg. 34).

 Turn the shaft by hand using the bolt.

 Remove the M6 or M8 bolt again.



You have two options for the standstill:

Either the pump-motor unit remains

connected in the system,

or the unit is removed for storage.
