heater elements and the cavity side walls. 5. Locate the stainless steel door interlock pin in the accessory box. One end is smooth, and the other end is threaded. 6. There is a threaded hole in the bottom/outside corner of the inside flange of the door. Thread the stainless steel pin into this hole and rotate it all the way until the pin threads bottom out and you can no longer rotate it by hand.
NOTE: The 3 AMP circuit breakers must be set (pushed in) in order to apply power to the Muffle Heaters. CAUTION: ALWAYS DEACTIVATE ALL THREE CIRCUIT BREAKERS AND DISCONNECT THE MAINS CORD FROM THE POWER SOURCE BEFORE SERVICING THE OVEN. IMPORTANT NOTE ON KILN FURNITURE PLACEMENT A sintering tray, and lid, and tray liner bead sample are included with your Infinity ZR oven. There is an extra lid included as well.

Start / Stop button: Press to immediately start or stop a program. 3. Press the Up Arrow key to increase a number. The longer the button is pressed, the faster the numbers increase. 4.
is actually in a delay before Start time period. 11. Main Display A. The 4 digit display indicates the chamber temperature. B. When programming or reviewing, the main display indicates PROGRAM NUMBER, DELAY START time, HEAT RATE, TEMP and HOLD TIME. C. Displays special words and error codes. 12. Program Status Graph indicates status of the sintering process. 13. Door Interlock Safety Switch shuts off electrical power to the heating rod elements when the furnace door is opened.
2. Press Up Arrow button and Down Arrow button at the same time. The degree light switches to the opposite temperature scale and the displayed value switches to those units. TO TURN THE “BEEP” ON AND OFF When a program is completed, 20 "beeps" sound every 15 minutes to inform the operator that the Sintering cycle is completed. 1. Be sure the Infinity is in the IDLE MODE – (no program us running). 2. Press the Up Arrow key and (while holding) press PROGRAM SELECT to display the status of the "beep.
7. For one stage, the furnace must be programmed not to use STAGE 2, 3 or 4. Follow these steps A. After completing step 6, press ENTER / REVIEW. STAGE 1 light turns off, STAGE 2 and HEAT RATE lights turn on. B. Press Main Display shows ".....5, 4, 3, 2, 1, COOL, NO. " Select "NO" to program the furnace not to use STAGE 2, 3 or 4. 8. All necessary information for this program is now entered. 9. To run the program immediately, press START / STOP. 10.
3. Press ENTER / REVIEW. HEAT RATE light turns off and TEMP light turns on. Use the arrow keys to scroll for the temperature required: heating temperature up to a maximum of 2822°F (1550°C) or cooling temperature down to a minimum of 137°F (58°C). 4. Press ENTER / REVIEW. TEMP light turns off and HOLD TIME light turns on. Use the arrow keys to program the time needed to hold at the above temperature (0 – 4hrs.). 5. For two stages, the furnace must be programmed not to use STAGE 3 or 4.
TO PROGRAM AND OPERATE – THREE STAGE PROGRAM 1. Follow Two Stage Program, Steps 1 – 4. 2. Press ENTER / REVIEW. STAGE 2 light turns off, STAGE 3 and HEAT RATE lights turn on. Main Display shows four heat rate choices. Choose one: A. Select heat rate between 1°F – 104°F /min (1°C – 40°C /min). B. Select "COOL" to program the furnace to cool to a selected temperature. C. Select "NO" to turn of STAGE 3 and 4. This will result in a Two Stage Program.
To start immediately, press START / STOP. Follow the same programming procedures if a three or four stage program is desired. *NOTE: When the temperature is set to a lower temperature than in the previous stage, the furnace ignores the programmed HEAT RATE (except for "NO") and automatically cools to the pre-set temperature. The time required for the cooling stage is determined by the pre-set temperature. The lower the temperature, the more time needed to cool down.
TO REVIEW A PROGRAM 1. Turn the power switch on. 2. Press PROGRAM SELECT. 3. Use arrow keys to select the program number to be reviewed. The program number (P1 – P30) will appear on the Main Display. 4. The number of stages in the program are indicated by the STAGE lights next to the Main Display. 5. Press ENTER / REVIEW. The DELAY (START) light turns on. The number of hours/seconds until the Program Starts appears on the Main Display.
4. To change a parameter while a program is running, press ENTER / REVIEW to advance to the desired STAGE and parameter (i.e. HEAT RATE, TEMP or HOLD TIME). Initially, STAGE 1 will appear. Any parameter can be increased or decreased by pressing the UP ARROW button or the DOWN ARROW button. 5. Any program can be stopped or started by pressing the START / STOP button. 6.
below.) No Numeric Display when power turned on. No Numeric Display and no other LEDs lit when power turned on. “ER-X” Codes display in the digital numeric display.

Turn oven power switch off, then on again. Check the building power source for tripped circuit breaker (40 amp). Refer to the Error Code list below.
Er7 THERMAL RUNAWAY Occurs when the temperature has exceeded 1600 C (2912°F) instantly or exceeded 1585°C (2885°F) for 1 minute . NOTE: Continuous “Beeps” occur when the Error Code appears on the Main Display until the START/STOP button is depressed. ROUTINE MAINTENANCE CLEANING INSTRUCTIONS Clean exterior of oven only by wiping the unit with a damp cloth coated with a mild, nonabrasive cleaner.
POWER FAILURE 1. If a power failure occurs, the Infinity ZR memorizes the conditions prior to the loss of power. When the power returns, the Infinity ZR returns to the proper point in the program. 2. When power is returned, the HR:MIN light flashes indicating that a power failure has occurred. It continues to flash until START / STOP is pressed. NOTE: The HR:MIN light flashes if the power switch is turned off and on while a program is running and START / STOP was not pressed.
