Lift Maintenance: Replace Canister Vacuum with Vacuum Pump Box

The Vacuum Pump Box is an industrial vacuum which will be installed in place of your canister/central vacuum.

1. Remove your canister vacuum
   
   1. At the vacuum, disconnect the two control wires by pushing on the speaker wire type terminal release:
      
   2. Remove the flexible hose from the vacuum by loosening the hose clamp and working the hose off the vacuum. Do not remove the hose clamp.
   3. Unplug the vacuum and remove the vacuum/mounting plate, if desired.
2. Position & connect the Vacuum Pump Box
   1. Locate the vacuum pump box in the final install location.
   2. Using the same wires disconnected in step 1.a, reconnect these wires to the speaker wire terminals located on the back of the vacuum pump box. Orientation does not matter.
   3. Insert the provided flex hose adapter (pictured below)into the hose where it previously connected to the canister vacuum and tighten the hose clamp to secure the adapter to the hose.
      
   4. Using the provided tri-clamps, connect the flex hose to the flange on the top of the vacuum box
      
   5. Plug in the vacuum
3. Installing the 3 way valve
   
   Overview:
   
   
   
   1. Ensure compressed air is shut off and all pressure is drained from the system.
   2. Install the push-connect elbows into the 3 way valve. Note that, while stiff, the elbow rotates independent of the hex head portion of the adapter. Insert air lines with a length of ~30cm into the adapters.
   3. Install the 3 way valve directly to the cyclone in line with the flex hose. Ensure port "B" is next to the cyclone (port "A" should be further from the cyclone than port "B")
      
   4. Cut the existing airlines running between the solenoid box and the mounting plate and insert T's in the cut position. Connect Port A and Port B to the newly installed T's.
      Note: When the vacuum is activated, the ball valve should immediately close and coffee should lift. If the ball valve opens when vacuum is activated, swap the connection between port A and B.
4. Reprogram the control box
