Install the Machine Stand Coolant Kit

Install the Machine Stand Coolant Kit (PN 50931)

  1. Because the coolant pump is dual voltage, you must verify that the motor strapping is correct before you install it:

    1. Remove the access cover on the coolant pump, and then identify the jumper configuration diagram.

b. Verify that the jumpers are in the correct configuration (120 Vac or low volt) for your installation. If necessary, adjust the configuration. Go to " Adjust the Coolant Pump Motor Strapping".

  1. Remove the four M8 socket head cap screws pre-installed on the coolant tank. Set the screws aside.

  2. Put the coolant pump into the coolant tank, and secure it with the four socket head cap screws that you set aside in Step 2.

  3. Attach the provided 90° push-to-connect fitting to the coolant pump.

  4. Find the coolant tube, which you routed through the machine stand earlier. Attach the loose end of the coolant tube to the push-to-connect fitting on the coolant pump.

  5. Route the power cord on the coolant pump to the right side of the machine, and connect it to the Coolant Pump Power outlet.

  6. Verify that the coolant setup operates properly:

    1. From the PathPilot interface, on the Main tab, select Coolant.
      The coolant pump powers on.

b. Select Coolant again.
The coolant pump powers off.

Adjust the Coolant Pump Motor Strapping

Because the coolant pump is dual voltage, you may need to adjust the motor strapping.

  1. Identify the jumper configuration diagram.

  1. Remove the access cover on the coolant pump.

  2. Reference the configuration diagram and move the jumper to the 120 Vac (low volt) position. Don't change the position of any wires – just the jumper that connects the terminals.
