  4. Open A-Side inlet valve and recirculation valve on your PMC machine.
  5. Slowly open the air valve on the A-Side transfer pump to start introducing the AS Pump Flush through the A-Side of the machine.
  6. You will notice iso material being pushed out of the recirculation line into the purge pail. Continue to pump AS Pump Flush through the system until it comes out of the recirculation line clear, with no added coloring or debris.
  7. Shut the air supply feeding the transfer pump. This will stop all flow of material.
  8. Un-cap the A-Side of the PMC whip hose. Once un-capped, place the hose into the purge pail.
  9. Close the recirculation valve on the A-Side of the PMC machine.
  10. Slowly open the air valve on the A-Side transfer pump to start the flow of AS Pump Flush through the heated hose.
  11. You will notice iso material being pushed out of the whip hose into the purge pail. Continue to pump AS Pump Flush through the system until it comes out of the recirculation line clear, with no added coloring or debris.
  12. Now that this process is complete, the A-Side has been completely cleaned of any iso material.
  13. Remove the A-Side transfer pump from the pail of AS Pump Flush and place it into a 5-gallon pail of AP Pump Saver 195.
  14. Slowly open the air valve on the A-Side transfer pump to start introducing the AP Pump Saver 195 through the A-Side of the machine. Continue to pump the AP Pump Saver 195 until you have pure and clean AP Pump Saver 195 coming out of the end of the whip hose.
  15. Place the B-Side stick pump into a separate 5-gallon pail of AP Pump Saver 195.
  16. Slowly open the air valve on the B-Side transfer pump to start introducing the AP Pump Saver 195 through the B-Side of the machine and heated hose. Continue to pump AP Pump Saver 195 through the system until it comes out of the end of the whip hose, with no added coloring or debris.
  17. Once the entire system is full of clean AP Lube 190, slowly start to recirculate the AP Pump Saver 195 through the entire system. When doing this, it is best to let the PMC machine cycle while recirculating the AP Pump Saver 195.
  18. Once all these steps are complete, close the air on each transfer pump and re-cap the heated PMC whip hoses.

If you follow these steps, your slab lifting rig should be well-prepared for the winter storage period.
