Unpackaging 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.
Installation Installation Site Selection: Install furnace on a sturdy surface and allow adequate space for ventilation. CAUTION Be sure ambient temperature does not exceed 104°F (40°C). Ambients above this level may result in damage to the controller. Allow at least six inches of space between the furnace and any combustible surface. This permits the heat from the furnace case to escape so as not to create a possible fire hazard.
General Operation of Furnace General Operation of Furnace WARNING To avoid electrical shock, this furnace must: 1. Use a properly grounded electrical outlet of correct voltage and current handling capacity. 2. Disconnect from the power supply prior to maintenance and servicing. 3. Have the door switch operating properly. To avoid personal injury: 1. Do not use in the presence of flammable or combustible materials ; fire or explosion may result. This device contains components which may ignite such material.
GENERAL OPERATION OF FURNACE Power Switch: Switch power switch to the “ON” position. The switch will illuminate when power is on. CAUTION If the power supply must be disconnected from the furnace at any time, be sure the chamber temperature is 500°C or less before doing so. FAN: The fan located in the rear of the control section will run continuously as long as power is supplied to the furnace, even when the furnace power switch is OFF.
Operation of Single Set Point Temperature Control (Automatic) Models 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. The control will cause the furnace chamber to heat to the chosen temperature and hold it at this temperature until you turn off the power switch or select another temperature.
OPERATION OF SINGLE SET POINT TEMPERATURE CONTROL (AUTOMATIC) MODELS When the tuning process is started the lower display will flash “tunE” along with the furnace temperature set point. During tuning the temperature set point cannot be changed. To change temperature set point “tunE” must be turned “OFF”.
Operation of 4 Ramp & 4 Dwell Programmable Models Operation of 4 Ramp & 4 Dwell Programmable Models Models F62730-80, F62730-26-80, F62730-3380, F62735-80) WARNING To avoid electrical shock, this furnace must have the door switch operating properly. NOTE For optimum control of a single set point operation, set the “CTrL” parameter to “FUZY” to take advantage of the controller’s fuzzy logic capabilities.
OPERATION OF 4 RAMP & 4 DWELL PROGRAMMABLE MODELS NOTE When examining the parameters, if you depress and release either the “SEL,” “UP,” or “DOWN” buttons and more than 1 minute elapses before the buttons are used again, the display screen will automatically switch to displaying chamber temperature. If this happens, you will have to step through each parameter until you reach the point at which the interruption occurred. The parameter values you checked earlier, however, will not be lost or altered.

OPERATION OF 4 RAMP & 4 DWELL PROGRAMMABLE MODELS how far the furnace chamber temperature can rise above your set point. We recommend a setting of 20; since a P.I.D. control process involves some degree of temperature overshoot, a setting of less than 20 may interfere with the function of your controller. CAUTION Remember that whenever the power switch is turned “ON,” the furnace will begin to heat at the set point temperature that was previously set.
OPERATION OF 4 RAMP & 4 DWELL PROGRAMMABLE MODELS NOTE If you desire to skip a ramp or dwell segment, follow this procedure: for a dwell segment, enter a setting of “0” minutes. for a ramp segment, enter a setting of “00.00” hour.minutes. This will cause controller to skip to next segment as fast as the furnace can heat or cool down. ter button (>) to select the current value. Push “UP” or “DOWN” button and set Ramp time 1 in hours and minutes in the format “X.XX” (hour.minutes).
OPERATION OF 4 RAMP & 4 DWELL PROGRAMMABLE MODELS or program or the type of load you are heating. To use the Tuning feature: NOTE For processes which cannot tolerate the overshoot naturally generated during the tuning process, select “Lo” rather than “on” for the “AT” setting. The “Lo” setting will tune your furnace at a temperature below your set point, then apply the result to your set point. This approach prevents the necessary tuning overshoot from exceeding your actual set point. 1.
Furnace Loading CAUTION Do not overload your furnace chamber. If the load is to be heated uniformly it should not occupy more than the center two-thirds of the furnace chamber. Failure to observe this caution could result in damage to furnace components. 2. If you are heating a number of small parts, spread them throughout the center twothirds of the furnace chamber. 3. Keep objects away from thermocouple. 4. Use insulated tongs and mittens when loading and unloading furnace. 5.
