Wiring

Wiring the Vacuum Press

You don't need an electronics degree to successfully wire the system but you must be aware of the essential practices and principles of safety when working with 120 volts. Do not proceed to wire this system without the help of a certified electrician if you are uncomfortable working with electrical components, or if you are unfamiliar with the risks associated with electricity. Be sure to read, understand, and agree to the terms and conditions found on this page before proceeding.

If you are soldering the wires to the vacuum controller, be careful not to damage the vacuum controller by over-heating the tabs. Allow the soldering iron to reach full heat before you begin. Then apply solder to the common and normally closed tabs. Next apply solder to the wire ends. Lastly, reheat the wire ends onto the tabs. This last step should not require any additional solder. Be sure to adequately insulation any exposed wire near the terminals.

f you opt to use crimp-on connectors, simply strip off 1/4" of insulation and insert the wire into the connector and crimp the plastic area of the connector with a pair of pliers.

Parts used in this section: Tools Required:

Light switch
Light switch plate
Handybox
Romex box connectors (2)

Wire nut
Screws - #8 x 1/2" (2)
Electrical power cord
Crimp-on connector (optional)

Soldering iron
Wire cutters
Screw driver

  1. Light SwitchAttach two Romex box connectors to the utility box.
  2. Remove the "ears" from the light switch.
  3. Utility boxes usually have a couple of small holes in the back of the box which can be used to mount it to a wall or other attachment surface. Using these holes, attach the utility box to the top of the carrier with two small screws. Be certain that the screws do not protrude through the bottom of the board.
  4. Knock out two of the utility box holes and insert a Romex connector in each as shown in the picture below. Tighten the locking nut on each connector.
  5. Insert the electrical cord into the box through one of the connectors leaving 3" of wire inside the box. To make the wiring process easier, do not tighten the locking screws on the Romex connectors yet.
  6. Cut one of the wires from the Mac valve just longer than needed to reach the common tab on the vacuum controller. Attach this wire to the vacuum controller with solder or a crimp-on connector.

    Important:
    The terminals on the vacuum controller are covered by a removable plastic lid. Remove this piece for easy access to the tabs by pulling upward on it. See the animation at the top of this page. Be sure to attach the wires to the correct terminals.
     
  7. Using the remaining piece of wire that was cut off in the step above, attach one end to the normally closed terminal on the vacuum controller with solder or a crimp-on connector. Keep in mind that the normally open tab on the vacuum controller is not used.
  8. Insert the other end of this wire into the utility box and attach it to one of the terminals on the light switch (not the ground terminal).
  9. Insert the remaining black wire from the Mac valve into the utility box and with a wire nut, attach it to the white wire (neutral) from the power cord. If the power cord you are using is all black, the wire with the ribbed texture is the same as the white (neutral) side.
  10. Attach the black wire from the power cord to the opposite terminal on the light switch (again, not the ground terminal).
  11. Tighten the locking screws on the Romex connectors so the wires are firmly kept in place.
  12. If your power cord has a ground wire, attach it to the green grounding screw on the light switch and the utility box.
  13. Attach the light switch to the utility box and screw on the light switch plate cover.

The final assembly should appear as shown in the picture below.

Vacuum Press Wiring

Wiring Check
Let’s re-examine the path of electricity. Start with the black wire from the electrical cord. The flow should go this way:

  • veneer press wiring diagramThe black A/C line goes to a switch terminal.
  • From the other switch terminal, a black power line is going to the normally closed tab on the vacuum controller.
  • The power then flows from the common tab on the vacuum controller to the Mac valve.
  • The remaining wire on the Mac valve goes to the white wire on
    the electrical supply cord.
