T e Operating Instructions are part of t e pump.
Carefully study t e Operating Instructions before using a
pump.
Always keep t e Operating Instructions andy in t e work
area.
Pass on t e Operating Instructions to t e next owner.
Customer-specific project pumps (pump models w ic begin wit
“PJ” or “PM”) may differ from t e Operating Instructions.
For project pumps, also observe t e agreed upon specifica-
tions.

2. Use
2.1. Proper use
T e pumps are exclusively intended for transferring gases and
vapors.
Owner's responsibility
Only install and operate t e pumps under t e operating parameters
and conditions described in C apter 4, Tec nical data.
Make sure t at t e installation location is dry and t e pump is
protected against rain, splas , ose and drip water.
Before using a medium, c eck w et er t e medium can be trans-
ferred danger-free in t e specific application case.
Before using a medium, c eck t e compatibility of t e materials of
t e pump ead, diap ragm and valves wit t e medium.
Only transfer gases w ic remain stable under t e pressures and
temperatures occurring in t e pump.
2.2. Improper use
T e pumps may not be operated in an explosive atmosp ere.
T e pumps are not suitable for transferring dusts.
T e pumps are not suitable for transferring liquids.
Pumps designed to create eit er a vacuum or an overpressure
must not be used for t ese two purposes simultaneously.
An overpressure must not be applied to t e suction side of t e
pump.

3. Safety
Note t e safety precautions in sections 6. Installation and
connection, and 7. Operation.
T e pumps are built according to t e generally recognized rules of
tec nology and in accordance wit t e occupational safety and
accident prevention regulations. Nevert eless, dangers can result
during t eir use w ic lead to injuries to t e user or ot ers, or to
damage to t e pump or ot er property.
Only use t e pumps w en t ey are in a good tec nical and proper
working order, in accordance wit t eir intended use, observing t e
safety advice wit in t e operating instructions, at all times.
Make sure t at only trained and instructed personnel or specially
trained personnel work on t e pumps. T is especially applies to
assembly, connection and servicing work.
Make sure t at t e personnel as read and understood t e operat-
ing instructions, and in particular t e "Safety" c apter.
Observe t e accident prevention and safety regulations w en
performing any work on t e pump and during operation.
Do not expose any part of your body to t e vacuum.
Open ousing parts wit notice sticker (see fig. 1) only after
separating mains plug from power source.
W en transferring dangerous media, observe t e safety regula-
tions w en andling t ese media.
Be aware t at t e pumps are not designed to be explosion-proof.
Make sure t e temperature of t e medium is always sufficiently
below t e ignition temperature of t e medium, to avoid ignition or
explosion. T is also applies for unusual operational situations.
Note t at t e temperature of t e medium increases w en t e pump
compresses t e medium.
Hence, make sure t e temperature of t e medium is sufficiently
below t e ignition temperature of t e medium, even w en it is
compressed to t e maximum permissible operating pressure of t e
pump. T e maximum permissible operating pressure of t e pump
is stated in t e tec nical specifications (see section 4).
If necessary, consider any external sources of energy, suc as
radiation, t at may add eat to t e medium.
In case of doubt, consult t e KNF customer service.
Store all replacement parts in a protected manner and dispose of
t em properly in accordance wit t e applicable environmental
protection regulations. Observe t e respective national and inter-
national regulations. T is especially applies to parts contaminated
wit toxic substances.
