the intake must be free from obstructions to ensure that the blowers can
get enough air to function properly.

nected and locked out.
MAINTENANCE
Periodically do a visual inspection on the unit to ensure that the unit is not
damaged and is operating properly with the motor spinning.

*Note that the air curtain blowers are direct drive so there are no belts to
maintain, and that motor is permanently lubricated so there are no fittings
that need greased.
