Setting internal head temperature
This is the procedure for setting the internal head temperature
1. Place the heads in the park position.
2. Remove the head covers.
3. Turn the solenoid control pot to the mid position. It is a 10-turn pot, so turn it
fully counterclockwise (it will click when fully counterclockwise) and then turn it
five turns clockwise.
4. Turn the knob on the trim heater control to 3.
5. Close the heads and monitor the head temp on the User Station. It should stabilize
at 41°C +/- 3°C (105°F ° +/- 5°F) in 30 minutes.
6. To increase the head temperature, turn the trim heater knob clockwise one number
at a time. To decrease the temperature, turn it counterclockwise.
