Placement of a protective screen is necessary if the I-fan:
•
is within reach of animals and/or people, and
•
is installed at heights less than 2.7 m above the floor.
The blades of the I-fan may run backward due to external influences. To prevent the I-fan turning in the
opposite direction, it is necessary to place a shutter. If the rotating speed of the blades in the opposite
direction is higher than 25% of the I-fan unit's maximum RPM, the I-fan is no longer able to reverse the
blades to the correct direction of rotation. Then, the I-fan will not start and will sound an alarm.
Disconnect the I-fan from the power supply before mounting the protective screen.
Make sure that the impeller is not turning.
Air inlet side
Install the protective screen on the I-fan and secure it as shown in the illustration below.
