2) Turn the control switch on the remote control cord to the “off” position and unplug the remote control
cord from the panel.
3) Turn the disconnect to the “off” position.
SAFETY NOTE:
DO NOT FILL THE HOPPER TO CAPACITY AT THE END OF THE DAY. THE MATERIAL
WILL COMPRESS AND CAN CAUSE MACHINE LOCKUP DURING THE FOLLOWING MORNING
START-UP.
Mechanical Settings:
The controls of your machine contain the blower and slidegate controls to adjust your machine for
each application and type of insulation. (See illustration 4 on page 14.) Blower control (air) and
slidegate (material feed) are adjusted according to:
TYPE OF MATERIAL: 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 4 on page 14.) 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
airlock which changes the production rate (lbs. per hour). (See illustration 4 on page 14.) For calibration
purposes the scale located on the machine indicates how many inches the airlock slidegate is opened.

Rev. Date: 5/11/23 Page 14
MODEL #5200-3E
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 4)
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 and agitator direction can be adjusted as described below.
Shredder & Agitator Adjustment:
Unidirectional Rotation (See illustration 5) 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 6) 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.

Airlock: (Seal Replacement)
The purpose of the airlock seal is to trap air and insulation until it rotates 180O to the 6:00 o'clock
position. At this point, insulation is pushed by air from the blower, out of the chamber. Worn or
damaged seals allow air and insulation to escape back into hopper, thus reducing production and
coverage. When it is necessary to replace seals, follow these directions:
Remove chain and air hoses from both input and output of airlock. Using a 5/8” socket, remove hold
down bolts from airlock. Lower the front of the airlock down by loosening the jamb nuts and turning the
lift bolts counter clockwise. Slide the airlock out of the machine. (See illustration 7) Airlock rotor plates
that are damaged (bent) will need replaced. (Refer to Rotor Plate Replacement below.) Take out
rubber seal by removing seven plate fastening bolts and nuts and top plate. The base plate will remain
attached to airlock shaft. To install a new seal, reverse procedure. Seal should be inserted tight against
the back base plate, pressing the lower tabs of the seal down under the adjacent seal with a flat blade
screwdriver. Make sure all bolt holes are aligned while each side of seal is equally pressed against the
end plates, before tightening bolts. Seal should be bent forwards for counter clockwise rotation.

Base Plate Replacement:
1. Remove damaged baseplate assembly from shaft using
ratchet drive wrench with extension and 9/16" socket.
2. Check seal for wear and damage. (Installing seal and top
plate on the bench is quick and easy). Remove bolts
from plate assembly and replace with new seal. Make
sure seal and top plate are assembled on correct side of
base plate before assembling in airlock. Seal should
press backward towards top plate when
installed cor-
rectly into airlock chamber. (Illustration 9)
3. Install the rotor plate assembly into the airlock. The
airlock runs counter clockwise viewing it from the
sprocket drive shaft. (Illustration 9) Align the base plate
with holes on airlock shaft using a tapered punch. Cau-
tion: Do not mount rotor plate backwards. If installed

(Note: Entire rotor plate assembly
may be removed and replaced. This
procedure maybe easier than
replacing just the seals.)
