SB-7-RC Auto-Calibration Procedure
Model:
PT-200RC & PT-56
Software version: 9098-K, 9099-L, 9098-M, 9098-N & 9098-O
Tools Required: Needle Nose Pliers
Process:
1. Turn booster heater power switch off and remove front cover. Open the
electronic drawer. Ensure that the software version on the microprocessor is
one that is listed above.
2. From the control circuit board remove the 2-pin (rear) jumper cap from
terminal marked Acal using pliers or fingers (see figure 200-14). Be sure
water in recirculating system is cooler than set temperature on booster
(under 140°F). If unable to verify, keep booster heater power off and run the
dishmachine rinse.
3. Turn booster heater power switch on. The unit will ignite and then stay in high
burn. Over the next 1 minu
te the gas flow will change slightly as the computer
determines the proper voltage for minimum flow. After the computer
completes auto-calibration the burner will automatically shut off.
4. Turn power to heater off for a minimum of 20 seconds.
5. Replace the jumper on the circuit board.
6. Turn power to heater back on. To check the unit for normal operation, run
several racks through the dish machine and ensure proper rinse temperature
is reached.
