1. About this document

1.1. Using the Operating Instructions

The Operating Instructions are part of the pump.

 Carefully study the Operating Instructions before using a

pump.

 Always keep the Operating Instructions handy in the work

area.

 Pass on the Operating Instructions to the next owner.

Customer-specific project pumps (pump models which begin with
“PJ” or “PM”) may differ from the Operating Instructions.

 For project pumps, also observe the agreed upon specifica-

tions.

1.2. Symbols and Markings

2. Use

2.1. Proper use

The pumps are exclusively intended for transferring gases and
vapors.

Owner's responsibility

Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4, Technical data.

Make sure that the installation location is dry and the pump is
protected against rain, splash, hose and drip water.

Before using a medium, check whether the medium can be trans­ferred danger-free in the specific application case.

Before using a medium, check the compatibility of the materials of
the pump head, diaphragm and valves with the medium.

Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.

2.2. Improper use

The pumps may not be operated in an explosive atmosphere.

The pumps are not suitable for transferring dusts.

The pumps are not suitable for transferring liquids.

Pumps designed to create either a vacuum or an overpressure
must not be used for these two purposes simultaneously.

An overpressure must not be applied to the suction side of the
pump.

3. Safety

Note the safety precautions in sections 6. Installation and
connection, and 7. Operation.

The pumps are built according to the generally recognized rules of
technology and in accordance with the occupational safety and
accident prevention regulations. Nevertheless, dangers can result
during their use which lead to injuries to the user or others, or to
damage to the pump or other property.

Only use the pumps when they are in a good technical and proper
working order, in accordance with their intended use, observing the
safety advice within the operating instructions, at all times.

Make sure that only trained and instructed personnel or specially
trained personnel work on the pumps. This especially applies to
assembly, connection and servicing work.

Make sure that the personnel has read and understood the operat­ing instructions, and in particular the "Safety" chapter.

Observe the accident prevention and safety regulations when
performing any work on the pump and during operation.

Do not expose any part of your body to the vacuum.

Open housing parts with notice sticker (see fig. 1) only after
separating mains plug from power source.

When transferring dangerous media, observe the safety regula­tions when handling these media.

Be aware that the pumps are not designed to be explosion-proof.

Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. This also applies for unusual operational situations.

Note that the temperature of the medium increases when the pump
compresses the medium.

Hence, make sure the temperature of the medium is sufficiently
below the ignition temperature of the medium, even when it is
compressed to the maximum permissible operating pressure of the
pump. The maximum permissible operating pressure of the pump
is stated in the technical specifications (see section 4).

If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.

In case of doubt, consult the KNF customer service.

Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and inter­national regulations. This especially applies to parts contaminated
with toxic substances.
