2.4 Appropriate Use
The product is to be used exclusively for
the intended use described herein.
The fans are only suitable for conveying
gaseous media without solids. Solids or
impurities contained in the conveying
medium must be filtered out before en-
tering the fan.
The intended use also includes:
•The temperature of the conveying
medium must be between -4.0°F (-
20°C) and +176.0°F (+80°C) in the
standard version.
•The temperature of the conveying
medium must be between -4.0°F (-
20°C) and +356.0°F (+180°C) for
special versions with heat shield.
•The fan is designed for S1 opera-
tion (continuous operation) and S9
operation (uninterrupted operation
with non-periodic load/speed
change) (according to IEC 60034-
1). To prevent damage, a maximum
of 27 cycles per hour are permitted.
•In the case of damp media, a con-
densation drain plug can be or-
dered. This is introduced into the
housing by the manufacturer.
The product may only be used if:
•This is in technically perfect condi-
tion
•The staff has the necessary safety
and danger awareness.
•The instructions in the operating in-
structions are followed.
2.5 Predictable Misuse
For a purpose other than the intended
use listed here, the fan should not be
used.
In principle, any use other than the in-
tended use is considered to be im-
proper. This means that safe operation
is no longer guaranteed. The operator
and not the manufacturer is responsible
for all personal injury and property dam-
age resulting from the improper use.
Predictable misuse also includes:
•The promotion of:
-Aggressive media
-Abrasive media
-Adhesive media
-Toxic media

TXP Inst. & Maint. Manual: IM

-Explosive media
-very humid (with droplet for-
mation) media
•Installation in an explosive atmos-
phere
•Series or parallel connection of sev-
eral fans
•Outdoor installation without special
measures
•Conversion and modification of the
fan
2.6 Modifications and Changes
Modifications to the fan are not permit-
ted for safety reasons.
The use of non-original spare parts may
void warranty and remove liability for the
resulting consequences. Therefore, al-
ways use only the original spare parts,
this applies especially to safety-relevant
components (impeller, motor, ball bear-
ings, runners, etc.).
2.7 Residual Risks
Fans are built according to the industrial
standard and are characterized by a
high level of operational reliability. Since
the fans are very powerful machines,
the following safety instructions must be
strictly observed to avoid injury, damage
to property and the machine itself.
Overview of Danger Points
The residual hazards of the fan are di-
vided into the following four areas:

Table 3: Assignment of residual hazards
For more information, see the following
chapters.
2.7.1 Hazards from Fans
Many residual hazards come from the
fan itself and are due to its intended
use. During operation, the impeller ro-
tates inside the fan and this can lead to
risks. As a protective measure against
these risks, the fan has a housing and a
protective grille on the suction side that
prevents the contact of the dangerous
areas. In the case of free-blowing fans,
a protective grille must be added on the
pressure side (available as an acces-
sory). Furthermore, pictograms inform
about potential danger points.
Dangers from moving in
During the operation of the fan, the im-
peller rotates at high speed. The air is
sucked in via the inlet opening. People
and objects in the vicinity can also be
sucked in.
WARNING!
Danger from being drawing
in at the inlet opening
During operation, air is
sucked in through the inlet
opening. Loose clothing, per-
sonal jewelry, scarves or long
hair can be sucked in. The
consequences are mild to se-
vere physical injuries, such
as shortness of breath due to
strangulation, abrasions, skin
injuries, etc.
Wear tight fitting clothing
Wear a hairnet
Take off personal jew-
elry such as necklaces
or bracelets before
working on the fan.
Do not wear ties or
scarves
Keep away from the inlet
opening during opera-
tion
Check the condition of
the protective grille regu-
larly
Wear h
ead protection, such as
hairnet, beanie, hairband
For long hair, wear a hairnet, a
beanie or a hairband so that it is
not possible to
suck the hair into
the fan
.
Danger from unexpected start-up of
the fan
The fan and its housing must be opened
during cleaning, maintenance and repair

TXP Inst. & Maint. Manual: IM
-825
15
work. In these situations, unexpected
start-up of the fan carries a great risk.
Therefore, the product must be discon-
nected from the power supply before
this work and secured against being
switched on again. Then wait for all
moving parts to stop. Only then can
work on the product be carried out.
Unexpected start-up can cause hazards
due to being drawn in if the fan starts
unexpectedly, hair, clothing or jewelry
can be sucked in and cause injury.
Disconnect the product from the power
supply even in the event of an unex-
pected failure or interruption of the
power supply. This prevents the product
from coming out unexpectedly and en-
dangering people nearby.
Danger from ejected parts
WARNING!
Risk of injury due to
ejected parts
When contaminants or ob-
jects enter the interior of the
product, they are ejected
from the exhaust outlet at
high speed during operation.
People affected by this suffer
serious injuries.
Use only clean media
without solids
Do not stay in the dan-
ger zone
Adhere to maintenance
and repair information
Wear protective gog-
gles
The fan is designed to convey clean air.
The protective grille at the inlet opening
prevents access to the inside of the fan
and also prevents larger foreign bodies
from being drawn in. Smaller foreign
bodies and particles in the sucked-in air
can still enter the inside of the product
and are deposited there as impurities or
are immediately ejected again. Deposits
can damage the fan or be ejected from
the exhaust outlet at high speed during
operation. People who are hit by ejected
parts can suffer serious injuries.

16 TXP Inst. & Maint. Manual: IM-
825
Danger from rotating parts
WARNING!
Risk of injury due to rotat-
ing parts
The fan impeller rotates at
high speed during operation.
If people reach into the rotat-
ing impeller, fingers or limbs
can be severed.
Do not reach into the
inside of the fan during
operation
Check regularly
whether the necessary
protective grilles are
present at the open-
ings and are intact
Replace missing or
damaged protective
grilles immediately
Wait until the impeller
stops before removing
protective grilles for
maintenance
After completion of
maintenance work, in-
stall all protective
grilles again. Access to
the inside of the fan
must be prevented.
The impeller inside the fan rotates at a
high-speed during operation. If objects
or limbs are put into the rotating impel-
ler, serious personal injuries are at risk.
In addition, these may be further pulled
into the impeller.
This residual hazard is an important part
of the function of the product. Without a
rotating impeller, media cannot be con-
veyed by the fan. For the protection of
people, the protective grilles are an im-
portant safety element. They prevent in-
terference with the inside of the fan.
However, during maintenance and re-
pair work, the impeller must be accessi-
ble to detect and repair damage to the
fan. For this work, the protective grilles
must be able to be removed.
To avoid dangerous situations and inju-
ries, it is therefore necessary to check
regularly during maintenance and repair
whether all protective grilles are present
and installed. Missing protective grilles
must be replaced immediately.
The fan is equipped as standard with a
protective grille on the inlet. The protec-
tive grille on the pressure side is op-
tional accessory. If the pressure side is
accessible and is not connected to any
ductwork, a protective grille must also
be installed here.
Danger from exceeding the maximum
switching cycles
WARNING!
Risk of injury due to com-
ponent failure
Exceeding the maximum per-
missible speed can lead to
breakdown of the impeller.
Fragments are thrown out of
the fan and can injure peo-
ple.
Adhere to the switching
cycles specified in chap-
ter "2.4 Appropriate
Use"
The impeller of the fan is designed for
high loads. Nevertheless, it can be dam-
aged by repeated, impermissible, rapid

TXP Inst. & Maint. Manual: IM
-825
17
starting and stopping. This breaks the
impeller and parts of it are thrown out of
the discharge side. People hit with frag-
ments suffer serious injuries. Adhere to
the maximum number of switching oper-
ations (see chapter 2.4) per hour and
the information on maintenance and re-
pair.
Danger from rotational speed
WARNING!
Risk of injury due to com-
ponent failure
Exceeding the maximum per-
missible rotational speed can
lead to breakdown of the im-
peller. Fragments are thrown
out of the fan and can injure
people.
Keep within the maxi-
mum number of rota-
tional speed or maxi-
mum frequency indi-
cated on the nameplate
The impeller of the fan is designed for
high loads and rotational speeds. If the
maximum permissible rotational speeds
are exceeded, the material can weaken
and break. This will destroy the fan and
seriously injure nearby people. Adhere
to the maximum speeds or maximum

Hazards from sharp edges, corners
and tips
CAUTION!
Risk of cutting due to
sharp edges, corners and
tips
Touching these areas can
lead to minor cuts.
Wear protective gloves
The impeller inside the fan has sharp
edges, corners and tips. Touching these
areas can lead to minor cuts. To avoid
these, the parts were deburred as far as
possible. In addition, the protective grille
on the suction opening prevents the in-
tervention in the housing and warning
signs on the fan warn of the danger.
Check the condition of these protective
measures regularly and replace them in
the event of damage.
Hazards due to the weight of the fans
During transport or installation of the
fan, there is a risk of the fan tipping over
or falling. In these situations, the fan is
not yet firmly screwed and its own
weight can injure people. Secure the fan
with suitable fasteners during transport
or installation and follow the instructions
in this manual.
2.7.2 Hazards from Electrical En-
ergy
The electrical connection of the product
to the power supply network as well as
work on the electrical equipment may
only be carried out by qualified electri-
cians, considering the relevant stand-
ards and regulations.
The electrical components of the prod-
uct must be checked at regular intervals.
Defects, such as loose connections,
damaged cables, must be rectified im-
mediately.
Keep moisture away from voltage-carry-
ing parts. Moisture can cause short cir-
cuits.

DANGER!
Danger when working on
voltage-carrying parts on
the fan.
When performing work on the
fan, you may encounter parts
that cause dangerous volt-
ages during operation.
Touching voltage-carrying
parts can lead to death.
Work on electrical in-
stallations/equipment
may only be carried out
by electrical profes-
sionals or electrically
instructed people un-
der the guidance and
supervision of an elec-
trical specialist in ac-
cordance with the elec-
trotechnical rules
The workspace must
be locked with a red-
and-white safety chain
and warning signs
The safety rules for
carrying out work on
electrical installations
and equipment must
be followed
Security policy
Observe the following safety rules for
carrying out work on electrical installa-
tions/equipment:
1. Disconnect the power supply
2. Secure against re-connection
3. Detect voltage leaks
4. Proper grounding and prevent
short-circuit
5. Cover or build barriers to adjacent,
voltage-carrying parts
2.7.3 Exposure to Noise
The fan causes noise during operation.
This residual hazard cannot be elimi-
nated as it is the result of the function of
the fan. Increased noise exposure can
lead to hearing damage or other health
damage. Therefore, always wear hear-
ing protection and stay in the vicinity of
the fan only when necessary.
WARNING!
Hearing damage due to
noise
Staying without hearing pro-
tection in the vicinity of the
running fan can lead to hear-
ing damage.
Wear a hearing protec-
tion from a daily expo-
sure level of 80 dB(A)
and/or a peak sound
pressure level of 135
dB(C).
The noise emitted by the fan is not con-
stant over the entire power range. The
radiated noise levels can be found in the
technical data.
The operator must perform a measure-
ment on the fan. If the statutory maxi-
mum values at workplaces are ex-
ceeded, the operator must carry out
sound insulation.

20 TXP Inst. & Maint. Manual: IM-
825
Sound insulation of any kind shall not
result in an undue increase in the ambi-
ent temperature above +104°F (+40°C)
on the drive motor.
2.7.4 Hazards from the Environ-
ment
Accessibility and location of the fan are
important safety factors. Therefore,
when installing and installing the fan,
ask yourself the following questions:
•How easy is it for outsiders to get
access to the facility?
•Does the fan pose a danger to the
environment?
•Has the system been tuned for the
application?
•Are additional safety precautions,
such as protective fences, neces-
sary?
•Can service or maintenance per-
sonnel easily shut down the fan via
accessible switches and secure it
against re-switching on?
All these issues are relevant to safety.
Only with respect for these aspects can
the fan be operated properly and safely.
2.7.5 Thermal Hazards
Hot surfaces on the fan housing
The fan housing assumes the tempera-
ture of the conveying medium during op-
eration. If this is above +122°F (+50°C),
the fan must be protected by the opera-
tor from direct contact. Touching hot
surfaces can lead to burns.
When conveying from the inlet side to
the outlet side, the temperature in the
conveyed medium can be increased.
Depending on the operating conditions,
this temperature difference can be in a
range of up to +176°F (+80°C) depend-
ing on the type.
WARNING!
Risk of burning due to hot
surfaces
Surfaces of the fan can heat
up. Prolonged contact (>1
sec) with these surfaces can
cause burns.
Avoid touching the hot
surfaces
Turn off the fan and
wait until the surfaces
have cooled down
Hot surfaces on the motor
The motor housing heats up during op-
eration. If the temperature rises above
+122°F (+50°C), the fan must be pro-
tected by the operator from direct con-
tact. Touching hot surfaces can lead to
burns.
WARNING!
Risk of burning due to hot
surfaces
Surfaces of the fan can heat
up. Prolonged contact (>1
sec) with these surfaces can
cause burns.
