REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor which can be removed with any standard solvent.
Follow the safety directions of the solvent manufacturer.
Blower inlet and outlet are temporarily capped to keep out dirt and other contaminants during shipment.
These covers must be removed before start-up.
The internal surfaces of all HeliFlow blowers are mist sprayed with a rust preventative to protect the
machine during shipment. Remove this film upon initial startup, using any commercial safety solvent.
Position the blower so that the inlet and discharge connections are in the vertical position (vertical
airflow). On vertically mounted units, it will be necessary to lay the unit on its side supporting the ends of
the unit so as not to restrict the portion on the bottom side. Place a shallow pan on the under side of the
unit. With the blower disconnected from power, spray the solvent in the top port, rotating the impellers by
spinning the shaft manually. Continue this procedure until the unit is visibly clean.
Rotating components will cause severe injury in case of personal contact. Keep hands away
from blower inlet and discharge ports.
