Make A Carrier
The carrier is made of three pieces of wood and holds the reservoirs in two ways. The top and bottom pieces are 8.5" wide and 10.5" long. The latter of these measurements is taken from the distance between the two PVC caps on the system. This holds the reservoirs in place horizontally.

The third piece of wood (the middle rail) for the carrier is 3.5" x 6.5". The critical measurement is 3.5" because it is slightly less than the diameter of the 3” PVC reservoirs. This is how the vacuum reservoirs are held in place vertically.

Parts used in this section: Tools Required:

3/4" Lumber or plywood
Wood screws- #8 x 1.5" (4)

Screws - #4 x 1 ¼" (2)
Screws - #4 x 5/8" (2)

Table saw
Screw driver
5/8" Drill bit

  1. Cut two pieces of 3/4" thick wood to 8.5" wide and whatever the length is between your reservoir caps.
  2. Make the middle rail with a piece of wood that is 3.5" wide by 6.5" long.
  3. Assemble the middle rail to the bottom piece of the carrier using two woods screws.
  4. Place the reservoirs units onto the carrier as shown.
  5. Drill a 5/8" diameter hole through the top carrier board. It should be centered on the width and approximately 1" from the edge. Now attach the carrier top using two wood screws. Do not over tighten these screws. You’ll only need enough pressure to hold the unit together and to keep the reservoirs from sliding inside the carrier.
  6. Now is a good time to attach a handle to the carrier if you want to easily carry the vacuum press around (see picture).

Attach the Vacuum Generator
Attach the VenturiUse two #4 screws (1 ¼” long) to attach the venturi to the top of the carrier. There are mounting holes for this purpose on top of the venturi. Pay attention to the positioning of the Mac valve. Be sure the body of the Mac valve is snug against the edge of the carrier as shown in the picture. This will remove the force from the small screws that hold the venturi in place when the quick connector from your air compressor is attached to the system.

Set up the Vacuum Controller
The vacuum controller regulates the pressure inside the system and turns the vacuum device on and off as needed. These are adjustable up to 28" of Hg. The vacuum controller is mounted to the system carrier and connected via vacuum tube.

Parts used in this section: Tools Required:

Vacuum controller (1)
1/8" NPTF barb fitting (1)

Black tubing (1)
Thread sealing tape

Wrench or pliers

Vacuum Switch There is a plastic nut threaded on to the vacuum controller. This part is not used so remove it and discard it. Also, the vacuum controller includes a small plastic barbed fitting in the box. It is also not used.

Wrap the threads of the vacuum controller with thread sealing tape and attach a 1/8" NPT barbed fitting onto the unit. Do not over-tighten the fitting. The maximum torque for the plastic body of the vacuum controller is 4 inch lbs. Attach a piece of tubing to the barbed side of the fitting and insert the tubing through the hole in the carrier so that the tubing is pushed forward toward the manifold. Use two #4 by 5/8" screws to attach the vacuum controller to the carrier. Do not over tighten these screws.
