4 - OPERATING INSTRUCTIONS
IMPORTANT: Always lock the casters during operation.
IMPORTANT: Make sure there are no paper or lightweight loose objects near the floor by the unit that could be sucked into
the bottom air intake. We recommend that you regularly clean or sweep the floor around the unit to extend the life of the
pre-filter.
1. Make sure the casters are locked.
2. Locate the ON/OFF switch on the rear side (Fig. 2).
3. Rock the ON/OFF switch up to the ON (I) position. It should illuminate.
4. Set the flow control on the desired airflow.
5. Observe the unit running for a short time to make sure there are no unusual noises, that air is freely flowing through the transition
and ducting, and the unit is not shifting position.
