Principles of Operation:
Accu1®9300 Insulation Blowing Machine
The Accu1®9300 insulation blowing machine moves insulation material to
specified areas by:
Conditioning insulation materials via agitator / auger shafts so that it can be
moved by pressurized air through hoses to the desired uninsulated spaces.
Insulation bales are loaded into the machine hopper. The agitator arms break up
the compressed insulation while the auger or shredder moves the material to the
air lock opening.
Agitator and Shredder
In the airlock, rotating vanes carry conditioned material to the air stream at the
bottom of the airlock. As the insulation passes by the air stream it is pushed
through the air lock exhaust tube and into the attached blowing hose. Further
conditioning of the material occurs as the insulation tumbles through the blowing
hose until it exits the hose end.

Maintenance
Check for the following:
Daily:
1) Clogged filters (Figure 1, right)
Figure 1
2) Insulation build up on motors and electrical components.
Figure 2
5

Weekly:
1) Belt tension and condition (Figure 2). The belt should not be frayed or slipping
on the pulleys. Replace the belt if it is damaged. Raise the belt tensioner to
remove any slack in the belt.
Monthly:
1) Airlock seals. Check airlock seals using a pressure gauge. A minimum outlet
tube pressure of 3.0 psi must be maintained for proper operation. Replace when
pressure drops below the minimum per the instructions in this manual.
2) Chain tension. Move chain tensioner(s) to remove any slack in the chain.
Note: Do not lubricate chain (Figure 2). Lubricants may attract foreign materials
to the chain and shorten it's life.

Warnings
1) Do not attempt to service machine while running.
2) Guards and doors must be in place at all times during operation.
4) Do not wear loose fitting clothing or jewelry while using this machine.
5) Keep hands, and arms out of the hopper (Figure 3) and away from any
moving parts.
Figure 3
6) Do not leave the machine unattended while running.
7) Keep hands and face away from hose end while machine is operating.
8) Only trained personnel who have read this manual should be authorized to
operate this machine.
9) Do not use objects to push material in the hopper.
10) Keep cutting tools (utility knives for example) away from the hopper opening
to avoid having these items fall into the hopper and damage the machine.

Operating Instructions
1) Starting the Accu1® 9300:
- Plug the (2) 9300 power inlets (Figure 3, black cords)into (2) dedicated
15 amp, 120 volt, grounded circuits using 10/3 AWG cords.
Figure 3
(Note: When using generators, make sure they are commercial grade and
and have a minimum wattage of 7500 watts).
- Attach hardwired remote to 9300 remote inlet (Figure 4, orange cord)
machine using remote cord. Make sure the remote switch is in the "Off"
position.
Figure 4
8

- Emergency Stop should be in the "Off" (out) position (Figure 5, red
switch).
Figure 5
- Open Slide Gate to the appropriate position and secure with pin (Figure
6).
- Depress Start Switch (Figure 5, green) and release. The control circuit
and remote are now actuated .
- Set remote switch to "On" for air & material and "Blower Only" for just
air.
2) Hoses:
- Attach 3" x 50' hose to the Airlock Exhaust Pipe (Figure 6, left) using a
hose clamp. Attach additional hose as required using the appropriate
connectors / reducers using hose clamps.
Figure 6
9

2) Stopping:
- Close the slide gate.
- Set the remote switch to "Blower Only" or "Air" depending on the
remote until the hose is clear.
- Turn remote to the "Off" position.
- Push Stop Switch (red). Note: This switch must be pulled out for the
controls to function.
3) Override Switch (use only when control circuit has failed):
- Flip up protective cover (Figure 5).
- Actuate toggle switch. Red Indicator Light, blower, and agitator motor
should come on. Remote will not affect the function of the override
switch.
- To Stop: flip toggle or protective cover down.

Machine Settings
Open Blow:
Slide gate fully open.
Air Speed: 8 - 10
Hose: 3"x 50' blowing hose all the way to the attic.
Wall Spray (all fibers):
Set slide gate open to 7"(10th hole).
Air Speed: 6
Hose: 3''x 50' to 3'x50' to 2.5"x50' to spray nozzle.
Dense Packing:
Set slide gate open to 3" (4th hole).
Air Speed: 6 (3.0 psi minimum)
Hose: 3"x 50' to 2.5"x50' to 2"x50' to reducer to wall tube.
Note: All the above are suggested settings and may vary depending on operating
conditions. For attics and dense packing, reduce feed slide gate opening if
clogging occurs. Increase opening to maximize production if material is moving
freely. For wall spray, reduce gate opening if material is too dry; increase gate
opening if too wet.

Airlock Seal Change Instructions
Regular maintenance on your Accu1® blowing and spraying machine will extend
the life of the equipment and provide better production. Replace all your seals as
soon as a decrease in production occurs (typically when the outlet pressure
drops below 3.0 psi). Airlock seal life may vary dramatically because of such
factors as the type and quality of the material used (the more abrasive the
material; the shorter the life) and damaging objects like knives, hammers, and
nails.
Tools required: pipe wrench, flat screw driver, 1/2" and 7/16" sockets, Allen
Wrench set, exterior/ clear/silicone window caulk, WD40 or similar penetrant.
To Replace Seals:
1) Flip the machine upside down.
2) Loosen chain tensioner.
Belt tentioner, airlock sprocket, chain tensioner, and large pulley
Figure 7
3) Remove chain.
4) Remove sprocket from airlock.

5) Remove the (2) bolts that hold airlock to front of the machine.
6) Remove the (8) screws holding the airlock to the bottom of the
hopper.
7) Remove blower connector hose (black) from airlock inlet located on
the square tube behind the airlock sprocket.
8) Remove blower support bar and blower and set both aside.
9) Use a flat screwdriver to pry the airlock off the 9300 cabinet. There
will be silicone caulk bead between the airlock and the hopper.
10) Lift up on the back of airlock and remove the airlock from unit setting
it on a flat surface.

12) Remove the (2) bearing retainers from airlock.
13) Loosen the set screws on the bearings and remove the bearings from
airlock rotor shaft.
14) Remove front plate from airlock.
15) Remove rotor and inspect for bent or damaged blades.
16) Remove felt washers from the rotor shaft.
17) Clean rotor and scrape silicone from airlock plate.

19) Put the rotor back into airlock in reverse order.
20) Apply silicone to airlock front plate put plate back onto airlock.
21) Replace bearings and retainers on airlock. Note: It's usually a good
idea to install new bearings when doing a rotor seal change.
22) Align rotor evenly between the front and back airlock plates.
23) Tighten bearing set screws. Use Loctite if available.

24) Reinstall seals so the thicker side (or side without seams) of the seals
touch the airlock shell.
25) Apply a thread penetrant like WD40 to the outside of the seals.
26) Using a pipe wrench on the sprocket, turn the rotor and seals.
27) Use a flat screwdriver to cup seals on edges.

28)Scrape old silicone off airlock and housing. Reinstall airlock the same
way as it was removed.
29) Put bolts back and tighten.
30) Replace blower support bar and blower and tighten.
31) Replace the sprocket and chain and line up chain tighten sprocket
and chain and tensioner.
32) Flip machine back over making sure everything is tight and secure.
33) Be sure to replace agitator paddles if worn will reduce production.
