MACHINE DAMAGE NOTE:
DO NOT FILL THE HOPPER TO CAPACITY AT THE END OF THE DAY. THE MATERIAL
WILL COMPRESSAND CAN CAUSE MACHINE LOCKUP DURING THE NEXT START-UP.
MechanicalSettings:
The controls of your machine contain the blower and slidegate controls to adjust your machine for
each application and type of fiber. (See illustration 7 on page 16.) Blower control (air) and slidegate
(material feed) are adjusted according to:
TYPEOFMATERIAL: Cellulose and fiberglass have different textures and densities that
respond to machine settings.
HOSE: Corrugations or roughness of interior surface, diameter, length and
elevation of hose will also require varying adjustments.
WEATHER CONDITIONS: Temperature and humidity may require day to day adjustment of
machine settings.
Blower Control and Slidegate General Settings:
Blower control can increase or decrease the amount of air in the system, affecting the velocity
(speed) and spread rate (coverage) of insulation. (See illustration 7 on page 16.) The blower control
valve is used for controlling air pressure and amount of air flow.
Opening or closing slidegate (material feed) controls the amount of insulation dropping into the
airlockwhichchangestheproductionrate(lbs.perhour). (Seeillustration7onpage16.) Forcalibration
purposes the scale located on the machine indicates how many inches the airlock slidegate is opened.

The blower and slidegate controls working together
affect the distance insulation can be blown through a hose
without plugging. These controls also affect the accurate
blowing of insulation for spraying applications.
These settings control the following:
•Density of insulation blown in application.
•Velocity of material impact when spraying.
•Dust on open blow.
• Material spread rate or coverage.
•Production rate (lbs. per hour blown).
General Blower Control and Slidegate Settings for Open Blow:
With the slidegate closed and blower control valve on low (valve open), turn agitator-feed and
blower on. Fill hopper with insulation and adjust blower valve and slidegate. Move controls
proportional to each other. (i.e. If blower valve is half open, slidegate should be half open.) As hose
length is increased, air pressure/volume is increased by closing off the blower valve while closing the
slidegate proportionally. This will increase the distance insulation can be blown through the hose,
while decreasing the blowing production rate (lbs. per hour blown). (See illustration 7)
Shredder Assembly:
This unit is supplied with a shredder assembly; airlock/agitator speeds are preset at the factory. No
further sprocket setting speeds are needed, as this system will accommodate most insulations and
applications. However, the shredder direction can be adjusted as described below.
Shredder Chain Adjustment:
Unidirectional Rotation (See illustration 8) is preferred as an all-around setting for a combination of
materials and applications. This setting provides the greatest coverage and best control for internal
wetting (stabilized) and open blow applications.
Center-Down Rotation (See illustration 9) force feeds the insulation into the airlock at a faster rate.
This direction provides the greatest production for cellulose insulation in an open attic blow applica-
tion although coverage may decrease.
