Frico UF600 Notice De Montage Et Mode D'emploi page 20

• Vibrations which may occur.
• Noises which may occur in the bearings of
the electric motor.
• The air duct should regularly be cleaned
through the inspection hatch.
NOTE! The power supply must always be
disconnected before disassembling any part
of the unit.
Overheating
Starter kit UFC is equipped with motor
protection for each one of the fan motors.
If there is an overload the motor protection
will trip, stopping the air curtain. The motor
protection must be reset manually.
If the motor protection is tripped please
check the fuses and if the air inlet is blocked.
Trouble shooting
If the fans are not working or do not blow properly,
check the following:
• Operating power supply to the unit;
check fuses, circuit-breaker, time switch/
thermostat (if any) that starts and stops the
unit.
• That the air flow selector is correctly set
• That the position limit switch is working.
• That the overheat protection for the motors
has not been deployed.
• That the intake grille/filter is not dirty.
If the fault cannot be rectified, please contact
a qualified service technician.
Drainage
If there is a risk of large amounts of water
running into the floor channel, a drainage
pipe should be connected to the existing 1"
connection (internal thread).
Do not connect the drainage to the sewage
(risk of blowing out water lock).
Start-up current
The external fusing must be adapted to the
motor start-up current.
Safety
- Do not cover surfaces of the air curtain or
obstruct air inlet, as this can cause excessive
temperatures that can be hazardous and may
cause fan motor malfunction.
- The air velocity will be too high for people
to go through the air flow. People should not
enter the opening without protection from a
vehicle etc.
Fig. 1 Dimensions
Fig. 2 The positioning of the columns
The fan pillar can be positioned on either side
of the door. For large doors, two fan pillars are
often required. They should be positioned one
on each side. When two units are placed on
each side of the doorway, the floor duct has
to be divided by a steel wall in the middle to
prevent the fans from working against each
other.
Fig. 3 Flange sizes
The tower is connected to the connection
box with flanges these sizes mounted on the
silencers. The AC600 flange comes with Ø12
mm holes.
Fig. 4 Connection box
The connection box is where the tower is
connected to the floor duct. The height
depends on the installation alternative
chosen. Please contact Frico for more
information.
Fig. 5, 5.1 Floor duct
The floor channel box is a steel construction
that is cast into the concrete floor. The outlet
opening is at floor level, as close to the floor
opening as possible. The length of the box and
the angle and column width is determined at
the project planning stage.
The channel can be made in one piece or
delivered in sections which are then welded
together on location and include air outlet
slot, connection box and inspection hatch.
Measures are suggestions. The air outlet slot
should extend approximately 100 mm outside
the edge of the door. Please contact Frico for
more information.
