SS: Purging and Priming
Training :: Soft Serve :: Purging and Priming
Priming your machine is crucial to the machine's operation. Not following these directions will result in damage to the machine and its components.
Gravity Fed Soft Serve Purge and Prime Guide
1.
Start with a
clean lubricated machine with the air tube removed.
2.
Pour no-rinse food-grade sanitizer into the hopper and put it in wash mode for 5-10 minutes (2 gallons
per hopper). Dunk the air tube into the sanitizer water in the hopper. (Do not touch the hopper agitator with the
air tube)
3.
Empty sanitizer
then press RESET.
4.
Ensure the white
plastic air tube is out of the hopper.
5.
Pour in about a
gallon of product.
6.
Pull on the
dispensing handle to purge the rest of the sanitizer until a solid flow of
product runs through. Release the dispensing handle.
7.
Pour in the rest
of your product.
8.
Lift up the prime
plug on the top of the dispensing door (NOTE: In single-cylinder models,
the priming plug is located on the top left side of the dispensing door. In
two-cylinder models there is a plug on both the top left and top right of the
dispensing door). Once a steady stream
of product is achieved push the plug back down.
9.
Add the white
plastic air tube back into the hopper. Ensure that the side with the small pin-hole-sized
hole faces up and the large product hole faces down.
10. Press RESET then FREEZE.
*Reinserting the air tube before priming the machine can lead to freeze-up and motor overloads.
Air Pump Purge and Prime Guidelines
*Before disassembling the machine to clean, make sure to depressurize the air pump. Once the product has been emptied from the machine, you want to make sure the machine is off then pull down on all three handles with a bucket in front of them. There will be a spray of product and once that has calmed down, you can release the handles, it has been depressurized, and you can continue to break the machine down.
1. Start with a clean lubricated machine with the
air pump installed and the injection tube removed.
2. Pour no-rinse food-grade sanitizer into the hopper
and put it in wash mode for 5-10 minutes (2 gallons per hopper). Take the
injection tube and dunk it into the sanitizer water in the hopper. (Do not touch the hopper agitator with the
injection tube)
3. Empty the sanitizer then press RESET.
4. Pour about a gallon of product into the hopper.
5. Pull on the dispensing handle to purge the rest
of the sanitizer until a solid flow of product runs through. Release the
dispensing handle.
6. Pour the rest of your product into the hopper.
7. Lift up the prime plug on the top of the
dispensing door (NOTE: In single-cylinder models, the priming plug is located
on the top left side of the dispensing door. In two-cylinder models there is a
plug on both the top left and top right of the dispensing door). Once a steady
stream of product is achieved push the plug back down.
8. Next put the unit in WASH mode and verify that a
strong stream of product is shooting out of the front of the pump.
- If so, continue to step 10.
- If not, verify the pump is clean and installed correctly. (NOTE: In two-cylinder models repeat on both sides.
9. Press RESET to stop the unit.
10. Install the injection tube into the hopper and
connect it to the pump ensuring to lock the tube to the air pump.
11. Press RESET then FREEZE.
*Reinserting the Injection tube before priming the machine can lead to freeze up and motor overloads.
