CAUTION

Danger of burns on hot surfaces

Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.

► Provide suitable touch protection.

NOTICE

Damage caused by unsuitable cleaning agents

Unsuitable cleaning agents damage the product.

► Do not use solvents as they attack the surface.
► Do not use any aggressive or abrasive cleaning agents.

Disassembly and cleaning

● When carrying out maintenance work, only dismantle the screw pump to the extent that

is necessary.

● Clean the pump parts using industrial alcohol, isopropanol or similar agents.
● Avoid residues of cleaning agent inside the screw pump.

Preparatory measures

1. Shut down the screw pump and allow the screw pump to cool as required.
2. Disconnect the motor from the mains.
3. Secure the motor against unintentional reactivation.
4. Close the cooling water feed.
5. Switch off the process- and pump-specific media supply (e.g. the sealing gas supply).
6. Vent the screw pump to atmospheric pressure via the vacuum side.
7. Allow the cooling water to drain completely.
8. Disconnect all connections.
9. Dismantle the screw pump from the system as necessary.

7.2 Checklist for inspection and maintenance

Notes on maintenance intervals

The times for the maintenance intervals depend to a great extent on the process condi-
tions; they apply for working with clean and inert gases. The use of corrosive process gas-
es can substantially curtail the maintenance intervals.

● Agree shorter maintenance intervals for extreme loads or for specific processes with

Pfeiffer Vacuum Service

Maintenance intervals

You can carry out the

inspection

yourself.

We recommend Pfeiffer Vacuum Service for carrying out maintenance work of

Mainte-

nance Level 1

and

Maintenance Level 3

(revision). If the required intervals listed below

are exceeded, or if maintenance work is carried out improperly, no warranty or liability
claims are accepted on the part of Pfeiffer Vacuum. This also applies wherever parts other
than original spare parts are used.
