6.In the Programming Mode, the number keys can be used to jump to menu levels without scrolling through them ALL. I.E., from 0 select Model in “DRYER SETUP”; you can jump to menu level five (5). Enter Lint Cleaning Frequency under “DRYER SETUP” by pressing the five (5) key followed by the

“START/ENTER” key to accept value. Light emitting diode (L.E.D.) display will read 5: LINT CLEANING FREQUENCY 1 TO 10 HOURS.

7.The basket (tumbler) temperature can be displayed by pressing and holding the “UP ARROW” key.

8.The programmed cycle parameter can be viewed by pressing the “START/ENTER” key followed by the “A-F” key. To view “0-40” cycles, press the “START/ENTER” key, followed by the number desired to view and then the “START/ENTER” key. The viewing can be stopped by pressing the “STOP/CLEAR” key at any time.

C.FIRE SUPPRESSION SYSTEM (F.S.S.) THEORY OF OPERATION

While the dryer is in an idle state, or 20-seconds after the heat turns off, the Phase 7 non-coin microprocessor controller (computer) monitors the thermistor probe located in the top of the basket (tumbler) chamber and records the minimum temperature. If the minimum recorded thermistor probe temperature is greater than 120° F (48° C) and the Phase 7 non-coin microprocessor controller (computer) detects a 50° rise in temperature, this will be the trip point and the F.S.S. routine will activate.

While a drying cycle is in process and the heat has turned on at least once, the Phase 7 non-coin microprocessor controller (computer) monitors the exhaust temperature transducer. If the drying cycle temperature set point is set greater than 160° F (71° C) and the Phase 7 non-coin microprocessor controller (computer) detects an exhaust temperature rise 25° F greater than set point, this will be the trip point and the F.S.S. routine will activate. If set point is below 160° F (71° C) the trip point will be 185° F (85° C).

Once the F.S.S. routine is activated, the Phase 7 non-coin microprocessor controller (computer) will display “F.S.S. ACTIVATED” and water will be injected into the basket (tumbler) chamber. Any time water is being injected into the basket (tumbler); the basket (tumbler) drive will turn the load for 1-second every 15-seconds. This process will continue for a minimum of 2 minutes. After the 2 minutes has elapsed, the Phase 7 non-coin microprocessor controller (computer) will check if the temperature remained above trip point, if so water will remain on. The Phase 7 non-coin microprocessor controller (computer) will continue to check if the temperature is above trip point every 30-seconds. If the water has been on for a constant 10 minutes, the water will be turned off regardless of the temperature and the Phase 7 non-coin microprocessor controller (computer) will display “F.S.S. WAS ACTIVATED”. If the temperature has dropped below trip point, the Phase 7 non-coin microprocessor controller (computer) will turn off the water prior to 10 minutes.

SYSTEM RESET

After the Phase 7 non-coin microprocessor controller (computer) determines that the situation is under control and shuts the water being injected into the basket (tumbler) off, the Phase 7 non-coin microprocessor controller (computer) display will read “F.S.S. WAS ACTIVATED”, and the horn/tone will sound until reset manually.

To reset the Phase 7 non-coin microprocessor controller (computer) once the Phase 7 non-coin microprocessor controller (computer) displays “F.S.S. WAS ACTIVATED”, press the red “STOP/CLEAR” key on the keyboard (touch pad).
