Calibrating the PFC-50

The first step in using the PFC-50 is to perform a one-time calibration. To do this:

Step 1. Charge the car to full using the standard Toyota charger. If you prefer to have the Manzanita charge to the

bottom of your sag point, wait 12 hours before continuing to Step 2, so that your RAV’s traction battery will sag to

90% or thereabouts.

Step 2. Set the Manzanita’s DIP switches #1 and #7 to ON; everything else OFF. Note that the switches are numbered

in descending order (8,7,6,5,4,3,2,1) from left to right and that ON is actually DOWN, not UP as you might expect.

Step 3. Ensure that the car is off and the key is removed.

Step 4. Turn off the GE breaker in the cargo compartment.

Step 5. Turn off the breaker on the PFC-50.

Step 6. Mate the Anderson connector to the Anderson connector on the PFC-50.

Step 7. Plug the 14/50 plug on the PFC-50 into the surface mount range receptacle.

Step 8. Plug your favorite high capacity cord into the marine connector.

Step 9. Plug the other end into a power source (e.g., 120VAC or 240VAC)

Step 10. Start the car. Confirm that the “Ready” indication is illuminated on the dashboard.

Step 11. Turn on the GE breaker.

Step 12. Turn the AMPS knob on the PFC-50 counterclockwise until it stops.

Step 13. Using a small screw driver, turn the voltage trim potentiometer clockwise until it stops.

Step 14. Turn the PFC-50’s circuit breaker on.

Step 15. Slowly turn the voltage trim potentiometer counterclockwise until the yellow “limits” light flashes (once) and

the blue timer light illuminates.

Step 16. Turn off the PFC-50 breaker.

Step 17. Turn off the GE breaker.
