general Receiving Unpacking Be careful not to damage or deform any parts of the blower when removing it from the packaging container. All the packaging material should be kept in the event the blower needs to be returned. Handling Handling of the blower should be performed by trained personnel and be consistent with all safe handling practices. - Page 5 general Never operate a blower with a non-ducted inlet and/or discharge. If the Caution blower inlet and/or discharge is non-ducted, it is the users responsibility to install an inlet and/or discharge guard. Temperature Many blowers, blower components and all motors operate at temperatures that could burn someone if they come in contact with them.

Page 6: Installation
installation Vibration Before any mounting method is selected, the user should be aware of the ef- fects vibration will have on the blower, motor and other parts. Improper blower installation can cause excessive vibration causing premature wheel and/or motor failure, that is not covered under warranty. Vibration eliminator pads, springs or bases should be properly installed to prevent any blower vibration from transmitting to the foundation or support structure. -
