How to change heat switch?

In the owner’s manual look on page 11 at the graphic of the control board. Power off. Remove only the access panel, the panel opposite the outlet tubes. Never remove the front Logo panel. Look inside to your left, take the 1/4" nylon nut from the dust cover, move the switch up one place for hotter, down one for less hot and give it a try. Replace the dust cover and access panel.

If the batch is discolored

The Sidewinder can only process what is put into it. It may be that you need to get rid of your waste and start fresh. We have, in the past run into a PPG product (primer???) that has resulted in discolored solvent and the people set up a timer that would limit the batch time and turn off power to the unit at about seven hours as the reaction to the PPG comes at the end of the batch.

Additionally remember that a bucket with a processing bag should be used and it should be at least 4 inches from the top. If the unit has had spills inside then run clean solvent over and over until clear.

  5. Unscrew compression fittings to free the end of the vapor tubes
  6. Take off the access panel
  7. Unscrew the fittings going into the evaporator to free the other end of the vapor tubes.
  8. Remove the vapor tubes.
  9. Blow air through the outlet tubes on the back of the machine to clear any clogs in the bottom fittings.
  10. Blow air through the holes inside of the pot to clear any clogs in the top fittings.
  11. Blow out vapor tubes to clear any clogs.
  12. Once free of clogs, put vapor tubes back in place.
  13. Before putting the skin back on, hold your thumb over each of the outlet tubes and pour solvent into each of the holes inside of the pot. Look for leaks.
  14. If leaking, you will need a new vapor tube. If not leaking, replace skin by reversing steps 1-4.

Jump Start the Refrigeration Unit

From time to time it may be necessary to test the refrigeration unit when your other controls are out or damaged.

When all circuit boards are removed and/or wire ends are secured so that they can't short to ground, make a temporary connect directly to the yellow and white wires that go to the refrigeration unit using a cord that can be plugged into a standard 110-120v outlet. Plug it in and observe, it may blow a breaker, it may turn on the unit. If it turns on feel at the end of the capillary tube coil that goes away from you horizontally into the evaporator. It should get noticeably colder.

Instructions for "Beep Tone"

There are 3 different beep tones 2 with interrupted tones and one steady uninterrupted. tone.

The most common cause of the interrupted tones is a blown F-4 fuse and dirty or blocked up condenser fins also check for build-up of debris on the fan blade. Look at page 9-11 in your manual. Do not remove the front panel that has the on/off switch. The side panel with the serial number is the access panel.

Steady uninterrupted tone. Missing or dead sensor. Do not remove the front panel that has the on/off switch. The side panel with the serial number is the access panel. Looking into the cabinet, which of the 4 bottom edge right side LEDs is lit on the control board. They correspond to the colored thermistors. Check page 11 in the manual to understand markings.

If it is a blown f-3 most likely you need a replacement Red thermistor it is highly advisable to keep the black and red thermistor from the same lot so both should be ordered.
