This is an instructional video on the proper procedures for replacing the disposable mix cartridge on the Slug Pro rigid polyurethane dispensing equipment. The following steps are easy, but important to ensure the proper operation of the Slug Pro.
Step one: disconnect the airline source, or close the airline ball valve.
Step two: close all four chemical ball valves.
Step three: disconnect the air purge line at the dispensing head.
Step four: remove the four bolts from the tee cap with a 3/16″ hex key, and set the bolts aside for re-assembly. Then remove the tee count.
Step five: remove the disposable mix cartridge assembly. Use a 1/8″ hex key to turn the two extraction screws clockwise to eject the disposable mix cartridge. Once loosened, fully remove and dispose of the mix cartridge. Then retract the extraction screws to the beginning flush position. It is important to return the screws to the original position, at or below the U-frame receiver, failure to do so could result in damage to the new mix cartridge. Remove the old grease and debris from the receiver. There is no need to use a spray cleaner, once the old grease is removed, apply fresh petroleum jelly or lithium grease to the walls of the U-frame receiver.
Step six: inspect the three new O-rings to assure they’re not damaged. Then, seat them into the new cartridge while lubricating each one with petroleum jelly or lithium grease.
Step seven: insert the new cartridge into the receiver. Align the cartridge so that the small O-ring is on top and the guide hole for the corresponding receiver guide pin is on the bottom. Once the cartridge is properly aligned, press firmly into place. Make sure the cartridge is flush with the bottom of the receiver.
Step eight: reinstall the tee cap with the four bolts. Then reattach the airline.
Step nine: grease the Slug Pro through the grease port, pump in grease until it flows from the deep hole underneath the U-frame receiver.
The Slug Pro is now ready for quality control. See our chemical system quality control procedures video for more information. If you have any questions, please contact the FSI technical service department.
