FUMEX FT
1000/1800/3000/5000/8000
5.5 Permitted applications
FT-fans are not to be used for conveying
aggressive, toxic or air with high humidity or
gas or explosive air-gas mix.
5.6 Sound level
The sound pressure level is not the same over the fans
whole range. In some cases it is necessary to use a
silencer. We recommend the user to check the sound
pressure level.
6 Installation
6.1 Transport
Check all parts for damage during transportation and
that the impeller runs free inside the housing. The fans
are to be installed in weather-protected places and are
not to be stored outdoors unprotected. Mount hoisting
hook carefully, and do only use lifting arrangements
with sufficient strength.
6.2 Arrangements and assembling
Mount the fan horizontally or vertically in a weather-
protected place. Make sure that the fan is protected
from vibration and shock. Supply open inlet and discharge
openings with guards according to valid regulations. Also
make sure that the drive motor is supplied with suffi-
cient ventilation. The permitted maximum temperature
of surroundings is 40 °C.
6.3 Electrical connection
The operations described in this part are to
be made by skilled labour only. Connect the
fan in accordance with the
Wiring diagram
(page 4) in the terminal box. The respective
VDE regulations and the directions of the
local power supply company are to be com-
plied with.
The fan is equipped with a drive motor for single- or
three-phase AC. The motor should be protected with an
overload switch. Connection to earth is to be found in
the terminal box. See last page for connection drawing.
6.4 Inspection of rotation direction
Start up the fan for a short moment, inspect the rotation
direction. The rotation direction of the impeller must be
in accordance with the arrow on the motor. If not, move
the L1 and L3 phases for three-phase operation or check
the wiring circuit in the terminal box for single-phase
operation. Incorrect rotation direction will cause reduced
capacity of the fan and could damage the impeller.
7 Start of operation
If the rated current indicated on the rating plate is
being exceeded during operation, it should be checked
whether the available supply voltage and frequency are
in accordance with the embossed data.
Installation of thermal protection is recommended
preventing overheating. Overloading can be avoided
through installation of relief valve which will keep the
maximum allowed working point. Do not expose the
fan to vibrations and shock.
8 Maintenance
Fans are equipped with enclosed grooved ball bearings
that do not need lubrication. The grease filling is suffi-
cient for the whole service life of the bearings.
Repair work on fans should be done by the
manufacturer. We do not take any responsi-
bility for repairs done by third parties.
9 Spare parts list
When ordering spare parts please state size of blower
and part number in ac-cordance with the spare parts
list.
