Component Operation and Checks
Transformer
Check the transformer as follows:
1. Make sure the wire from fuse 5 is connected to the proper terminal for the incoming
voltage.
• 208v – H2
• 240v – H3
• 480v – H6
2. Check voltage across terminals H1 and the terminal indicated in step 1. It should
read the same as the incoming voltage. If no voltage, check the breaker, fuses, and
wiring. Repair as necessary.
3. Check the voltage across terminals X1 and X2. It should be 20-28v. If not, the
transformer is defective.
Heater Controller
The wash temperature is controlled by the heat controller. The red illuminated display will
indicate the actual wash temperature on top and the set temperature on bottom. To adjust
the set temperature, push the “arrow up” and “arrow down” buttons. The range of
adjustment should be between 114 and 120 degrees.
