GROUNDING INSTRUCTIONS WARNING This equipment must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. DANGER - Improper connection of the equipment-grounding connector can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the cord or plug is necessary, do not connect the equipment-grounding connector to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the equipment is properly grounded. Do not modify the plug provided with the equipment if it will not fit the outlet, have the proper outlet installed by a qualified electrician. This equipment is for use on a nominal 120V circuit, and has a grounding plug that looks like the plug illustrated in sketch A. A temporary adaptor, which looks like the adaptor illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in sketch B if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet can be installed by a qualified electrician. The green colored rigid ear, lug, and the like, extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by the metal screw. SAVE THESE INSTRUCTIONS AC-900 Manual page 2

AVERTISSEMENT: Pour réduire le risqué de débranchez avant le nettoyage ou l entretien choc électrique, Replace fuse with Fast Acting 250V, 5A fuse only Remplacer avec Fast 250V interim, 5A fusible seulement Description The Model AC-900 Automatic Mixer is designed to perform the complete mixing operation of cartridge packaged materials. Stroking of the dasher rod is accomplished by means of a reversing air cylinder and the rotation of the dasher rod is accomplished by a quiet, high quality, induction gear motor, therefore the service requirement for this unit are compressed air (60psi, 1.5 C.F.M.) and 115V, 60 Hz, 1 Phase, 5 Amps. The rotation speed of the motor is constant depending on load, but the stroking length and speed of the air cylinder can be varied by adjustments. The most effective stroking speed for most materials is between 16 and 22 strokes per minute. The stroke speed on the Model AC-900 Automatic Mixer has been pre-set at mid-point for the six fluid ounce cartridges, so the speed will be a few strokes per minute slower for the eight fluid ounce cartridges and a few strokes per minute faster for the two and one-half fluid ounce cartridges. AC-900 Manual page 3
The instruction plate attached to the left-hand side of the box lists the cartridge size/dasher rod size, the proper spindle number and upper stroke adjustment rod to use, and the correct setting in inches for the down stroke adjustment rod. This is a guide for full kits only. Most likely, the sealant you will be mixing is not a full kit. Select kit to be mixed and prepare for mixing as stated in the instructions on side of the box OR follow instructions below for a non-full kit / short package. Determine if cartridge is fully packaged or is a short package and make appropriate down stroke adjustment as shown on instructions on side of box. A cartridge is fully packaged when material in dasher rod has been injected or barrier has erupted, and the rim of plunger is 3/16 from end of cartridge while dasher rod is pushed all the way to touch plunger. If cartridge is not fully packaged, shorten down stroke by the difference in inches of the location of the plunger between a fully packaged cartridge and the actual location of the plunger. OR you can perform the following under Full Instructions : WARNING - Do not operate this device in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. WARNING - If materials spill, disconnect power and follow Safety Data Sheet (SDS) for spill cleanup procedure. WARNING Dispose of mixer in accordance with all applicable regulations. Quick Instructions: If you are not familiar with the mixer, please proceed to Full Instructions 1. Ensure the OFF / MIX switch on the top of the mixer is in the OFF position 2. Remove air cylinder cap assembly from carriage plate and insert cartridge, rod end first, through mounting hole in carriage plate. 3. Pull dasher rod down onto pins of the drive spindle. 4. Grasp cartridge and pull down until it is fully seated in carriage plate; then install and lock air cylinder / cap assembly by twisting pins (by hand only!) into carriage plate ears. 5. Turn timer knob to desired number of minutes for mixing. (If mix period is less than two minutes, timer must be turned past two minutes then returned to the desired time); keeping fingers and all extremities clear, flip switch on top of machine to MIX position which will begin the cycle of machine and mixing of material in cartridge. 6. When timer has completed its cycle, both air and electric power will be shut off and cartridge may be removed. AC-900 Manual page 4
7. Remove cartridge by first putting OFF / MIX switch in OFF position. 8. Unlock (twist) and remove air cylinder/cap assembly. 9. Remove dasher rod from drive spindle and then lift cartridge through carriage plate for use as required. CAUTION: Keep clear of all possible moving parts ie. Carriage plate cycling and spindle turning. CAUTION: Disconnect air supply and/or electrical power when equipment is not in use, and before servicing. AC-900 Manual page 5
Full Instructions Model AC-900 Automatic Mixer 1. Identify which kind of packaged material you desire to mix. Is it barrier or injection style? 2. Then, determine the size cartridge and rod you are desiring to mix, and use the appropriate spindle and upper adjusting rod. AC-900 Manual page 6
3. The upper rods are located on the back of the mixer in the rack and are numbered to make identifying the correct upper rod easier. AC-900 Manual page 7
4. Ensure the Model AC-900 Automatic Mixer is switched to OFF position on switch. This will make certain the machine does not cycle. 5. Ensure timer is set to 0, or no time. This will make certain the machine does not cycle. 6. Plug mixer into proper electrical outlet 110V for standard mixer. AC-900 Manual page 8
7. Plug mixer hose fitting (Hansen) into your regulated shop air supply. We recommend setting the shop air regulator between 60-90 psi: AC-900 Manual page 9
8. The air cylinder assembly regulator located on the back of the mixer is preset at the factory to 12psi. If adjustment is needed, carefully follow these instructions, otherwise proceed to step #9: Turn the Model AC-900 Automatic Mixer around so that you can access the back of the machine. Keep clear of all possible moving parts ie carriage plate cycling, and spindle turning. Carefully and continuing to keep clear of all moving parts, flip switch on machine to MIX then turn timer slightly to get machine to turn on and cycle. The mixer will immediately cycle and dry run. This will allow you to set the regulator on the back of the Model AC-900 Automatic Mixer for the cap assembly. The purpose of the cap assembly is to hold the plunger in place when the cartridge is locked into the carriage plate. You can only set the pressure of this regulator when the mixer is cycling. As mixer is now cycling, pull black knob out on the regulator, turn to the desired pressure, then push knob back in to the locked position. We recommend setting this regulator at 10-12psi for most materials. Turn machine to OFF and set timer back to 0. Turn the Model AC-900 Automatic Mixer back around to access the front of the machine. 9. The mixer is now ready for you to prepare the packaged material. Depending upon the type of packaged material, either inject the catalyst into the base (for injection style) according to manufacturer s instructions OR remove barrier tape band, depress firmly around this area to break barrier, then push dasher rod to the back of the cartridge to the plunger to push the barrier all the way to the back of the cartridge so that it is out of the way for mixing. Remove any flange cap from the back of the cartridge if necessary. AC-900 Manual page 10
10. Push and twist firmly, yet carefully the dasher rod so that the dasher blade inside the cartridge is seated against the plunger located at the bottom of the cartridge. This is basically performing a full down stroke for the cartridge of material you are preparing to mix. AC-900 Manual page 11
11. Firmly with both hands, carefully pull up on the carriage plate assembly towards the MANUAL DOWN poppet valve : 12. Place cartridge into carriage plate assembly, rod end first, and place dasher rod onto spindle pins. Note that the carriage plate will move down as you perform this AC-900 Manual page 12
13. Pull cartridge down into carriage plate so that the cartridge flange is seated into the carriage plate and lock into place with the cap assembly. Push MANUAL UP poppet to release air, if necessary. Tighten by using the pin for leverage, but only tighten by hand. Do NOT over tighten and do NOT use tools such as a hammer, etc. 14. Now, loosen knurled knob that s holding the adjusting rod assembly. AC-900 Manual page 13
15. With both hands, pull down firmly on carriage plate assembly until mixing blade seats onto plunger inside cartridge. You will feel the resistance as you pull down. AC-900 Manual page 14
16. Turn / screw adjusting rod assembly until it pushes down on the poppet valve on the mounting plate about ¼ of the way down. Lock it down with the knurled knob. 17. This is now the distance you have set for the down stroke of the machine to the cartridge you are mixing. You may need to fine tune the length of the stroke slightly. Do this by the adjusting rod. 18. Make certain machine is clear and safe to cycle. AC-900 Manual page 15
19. Turn machine to MIX KEEP CLEAR OF ALL MOVING PARTS 20. Turn timer to material manufacturer s specified mixing time recommendations KEEP CLEAR OF ALL MOVING PARTS MIXER WILL BEGIN TO CYCLE AC-900 Manual page 16
21. Mixer will automatically stop when timer reaches zero 22. You can test to see if the mixer is set up properly by holding in the poppet valves and observing the dasher inside the cartridge spinning at the up stroke and the down stroke. 23. When time expires at the determined amount of time, the mixer will automatically stop. Turn switch back to OFF, and then remove the now mixed cartridge of material by removing the air cylinder assembly, and then the cartridge. Your material is now mixed and ready to dispense!

FAQ: ARE THE CAP ASSEMBLY PINS SUPPOSED TO FULLY ENGAGE THE CARRIAGE PLATE EARS? The pins slightly engage the two carriage plate ears. The pins may not necessarily engage fully when the machine is new. As the carriage plate wears and with cartridge variation, the pins will engage the ears deeper. The third pin must face the operator and is only used to hand tighten the cap into the carriage plate. Do not tap on the third pin with a hammer or other tool. This may damage or break the carriage plate. The motion of mixing a cartridge naturally tightens the cartridge into the carriage plate. The cap assembly is only used to keep the cartridge in place and from rotating. If the material is highly viscous, you may need to adjust the regulator on the back of the Model AC-900 Automatic Mixer to slightly increase the air pressure to hold the plunger in place. If required, we recommend increasing in 2 psi increments until the proper pressure is achieved. This varies based upon materials, but 10-12psi should be sufficient for most materials. (To adjust, see step #8 above) AC-900 Manual page 18
FAQ: HOW DO I ADJUST THE UP STROKE AND/OR DOWN STROKE SPEED? The mixer is set at the factory to mix approximately 20 strokes per minute at 60 psi. However, you may need to adjust the stroke speed depending upon materials and/or type of packaging you are using. ADJUST THESE SCREWS ON THE PILOT VALVE COUNTERCLOCKWISE TO SLOW DOWN THE SPEED OF THE STROKE. ONE SCREW IS FOR THE UP STROKE, THE OTHER IS FOR THE DOWN STROKE. YOU WANT TO KEEP THEM EVEN WHEN MIXING. The upper screw adjusts the up stroke speed. The lower screw adjusts the down stroke speed. (View from the back of the Model AC 900 Automatic Mixer) AC-900 Manual page 19
