1 Safety
1.1
1.1 General
The fan meets the technical safety standards
applicable in the EC at the time of delivery. The
rules and regulations for the prevention of accidents
applicable at the time of delivery were taken into
account in the fan design.
The technical design meets DIN 24166 standard
“Technical delivery conditions for fans”.
It is not allowed to modify the original condition of
the fan without the approval of Reitz. The warranty
expires when parts other than original Reitz spare
parts and/or purchased parts not corresponding to
the original parts are used.
Any variation or repair work has to comply with the
brochure ”Safety instructions for the application of
Reitz products”. Please request the brochure from
us if it has not yet been supplied.
The operating manual and any required
supplementary manuals must be available to the
operator.
It must be ensured that fans which are installed at
high levels can only be reached via stages
especially installed for this purpose.
All devices and installations provided to prevent
noxious substances from escaping must be checked
before the fan is put into operation.
Do not bypass, loosen of remove guards
and protective devices.
Do not open inspection ports and/or other openings
when the fan is in operation.

1.2
1.2 Description of symbols and
pictograms
This symbol draws your attention to
dangerous situations. The operation
concerned may endanger persons and
cause injuries.
This symbol is used to indicate that the
work must be carried out by a trained and
qualified electrician.
This symbol is followed by supplementary
information.
1.3 Start-up
The fan may only be put into operation (also for
testing) when the inlet and discharge ports are
provided with suitable guards/plate shutters or when
the fan is ducted.
Before the fan is started the housing and all duct
work connected to it must be checked. They must
be dry and free of screws, bolts, tools and other
foreign substances.
Disregarding the above instructions may
cause accidents and destroy the fan.
Observe the safety regulations for electrical
machines and equipment.

1 Safety
1.3
1.4 Servicing
The fan may only be serviced when the electrical
system is dead, i.e.:
— turn off the electrical machines and ensure
that they cannot be switched on again,
— wait until the rotor has come to a standstill,
— remove the motor fuse,
— disconnect the power supply cable for the
motor.
After servicing all guards and protective devices
must be installed and the fan must be ducted again.
All bolts and nuts must be tightened. Close all
inspection openings and tighten the bolts and nuts.
The fan can then be put into operation again.
1.5 Cleaning
Do not clean moving parts when the fan is in
operation!
Before cleaning the fan must be put out of
operation. Ensure that the fan cannot be switched
on again accidentally. Only use suitable detergents
and cleaning materials.
Remove any dirt wiped off the impeller from the fan
housing.
If material is sticking to the impeller or the
impeller is worn, the fan may be seriously
damaged by unbalance. It is therefore
recommended to clean and check the fan
for unusual vibrations at regular intervals.

1.6 Electrical safety
The user has to ensure that the fan is only
connected and serviced by a qualified electrician in
accordance with the rules and regulations applying
to electrical equipment.
The user must also ensure that the fan is operated
in accordance with electro-technical rules and
regulations.
Do not touch/work on live parts.
— Interrupt the power supply to the fan and
use mechanical means to ensure that power
supply cannot be switched on again.
— Use a voltage tester to check that the circuit
is dead.
— Connect and short the work site to earth.
— Only use the fuses indicated in the electric
circuit diagram.
— Check the condition of the visible cables
before the fan is started.
— Replace damaged cables.
Damaged and/or defective electrical equipment
must be repaired or replaced immediately. If the
damaged equipment represents a risk, the fan may
not be put into operation before the defect is
repaired.

conditions are also entered on the fan data sheet.
2.2 Warranty
The warranted data refer to single values and
testing conditions in accordance with the applicable
DIN standards and/or codes of practice. The special
characteristics and local conditions of the plant in
which the fan is to be incorporated must be taken

The model MEE fan is a welded single-stage radial
fan. It is driven directly by the motor shaft on which
the impeller is mounted.
For special designs please note the
information given on the fan data sheet.
The shaft passage is sealed with a graphite cord.
This seal is not completely tight. For
special shaft seals please refer to the
information provided in the annex.
3.2 Options
Accessories are available to adapt the fan to certain
specific plant characteristics.
For additional information see (→Annex).
