Calibrating the Pump Speed Display
The melter is shipped with the pump speed display calibrated to show the
pump rpm. If recalibration becomes necessary, follow this procedure.

without a tachometer.
1. Set the motor speed as follows:
 If using a tachometer, ensure that the motor is running at 50percent
speed or higher.
 If not using a tachometer, set the motor speed to 100 percent.
2. Press and hold both Pump speed arrow keys.
3. When the pump speed display indicates CAL, release the keys.
4. Use the Pump speed arrow keys to enter the actual pump rpm as
follows:
 If using a tachometer, enter the rpm value indicated by the
tachometer.
 If not using a tachometer, enter a pump rpm value of 80.
5. Press the Pump mode key.
