Introduction Intended Use The Type F62700 furnace is a general laboratory and heat treating furnace. For optimum element life, it is suggested that this furnace be used for applications requiring temperatures from 400°F (204°C) to 1600°F (871°C) for continuous use, or temperatures from 1600°F (871°C) to 1832°F (1000°C) for intermittent use. Continuous use is operating the furnace for more than 3 hours and intermittent use is operating the furnace for less than 3 hours.

Unpackaging Visually check for any physical damage to the shipping container. Inspect the equipment surfaces that are adjacent to any damaged area. Open the furnace door and remove packing material from inside the furnace chamber. Vacuum the chamber prior to use to remove the insulation dust due to shipping. The furnace is supplied with two hearth plates. Place the hearth plates on the bottom of the chamber. Install ceramic sleeve into top vent hole on furnace case.
Operation Single Set Point Temperature Control (Automatic) This furnace controller consists of a microprocessor based three-mode (Proportional, Integral, Derivative), single setpoint temperature controller. The controller features programmable overtemperature protection and thermocouple break protection. NOTE The temperature control in these models is a single set-point device. By using the "up" or "down" push buttons a specific temperature can be chosen.
Initial Startup: When the power switch is turned on the controller will perform a self-test to make sure controller is operating properly. (If all four 1’s do not light up or fails to go to “8888” contact Thermolyne.) Adjustment of Parameters: (See Figure 1, page 4) To illuminate down ▼ button, scroll button, and up ▲ button, touch anywhere on front panel. Set Point Temperature: Push up ▲ button or down ▼ button, to modify temperature set point (lower digital display).
High Alarm (Over Temperature Protection OTP): Push scroll button until “AL.SP” (Alarm Set Point) appears. The lower display should indicate 1010°C. NOTE HiAL- HIGH ALARM. (over-temperature protection, OTP) The controller is fitted with a mechanical relay which is de-energized in the alarm mode. This relay, when de-energized, removes power from the heating elements. If the primary control circuit fails, the OTP will control the furnace temperature at the preset value you have entered.
Preventative Maintenance WARNING THIS FURNACE CONTAINS REFRACTORY CERAMIC INSULATION WHICH CAN PRODUCE RESPIRABLE FIBERS AND DUST WHEN HANDLED. THESE FIBERS CAN CAUSE IRRITATION AND CAN AGGRAVATE PRE-EXISTING RESPIRATORY DISEASE. THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC) HAS CLASSIFIED REFRACTORY CERAMIC FIBER AS POSSIBLY CARCINOGENIC.
Troubleshooting The Troubleshooting section is intended to aid in defining and correcting possible service problems. When using the chart, select the problem category that resembles the malfunction; then proceed to the possible causes category and take necessary corrective action. PROBLEM POSSIBLE CAUSES The power light does not illuminate. The furnace is not connected to power supply. The furnace does not heat. CORRECTIVE ACTION Check furnace connection to power source.
PROBLEM POSSIBLE CAUSES CORRECTIVE ACTION Door switch does not cut power to heating elements. Door switch is not functioning. Re-align or replace door safety switch. Repeated element burnout. Heating harmful materials. Clean up spills in and on chamber. Ventilate chamber by leaving top vent slightly open when heating known harmful reagents. Install proper element. Wrong element. Replace thermocouple. Oxidized thermocouple. Contamination present from previous burnout. Wired improperly.
Maintenance and Servicing WARNING THIS FURNACE CONTAINS REFRACTORY CERAMIC INSULATION WHICH CAN PRODUCE RESPIRABLE FIBERS AND DUST WHEN HANDLED.
