PRECAUTIONS FOR SERVICING THIS EQUIPMENT Disconnect electrical power to equipment prior to performing cleaning or other service. In order to avoid electrical shock, injury and/or equipment damage, use appropriate precautions whenever electrical power must be restored for adjusting, calibrating or taking voltage measurements. Ensure that input power matches the nameplate data for voltage and phase. Input power circuit must meet or exceed the nameplate power requirements. Equipment is equipped wi

TROUBLE SHOOTING CAUTION: ELECTRIC SHOCK HAZARD Live electrical circuits are exposed during troubleshooting procedures CAUTION: BURN HAZARD Equipment surfaces will be hot during troubleshooting procedures B. TEMPERATURE CHECKS 1. Desired baking temperature is 390ºF ±5ºF (200ºC ±3ºC). 2. Turn the power switch ON and allow the Waffle Baker to heat for a minimum of 30 minutes. Insert a pyrometer of known accuracy betwen the grids and allow the readings to stabilize. 390ºF CALIBRATION 3. Tempe

D. VOLTAGE CHECKS NOTE: Resistance of the temperature probe is typically 5 megohm at room temperature, with resistance decreasing as temperature rises. A shorted temperature probe will cause a runaway condition, and an open probe will cause a continuous OFF condition. 1. Voltage between temperature controller terminals 2 & 3 will be 120V any time the power switch (item 66) is turned ON. Absence of 120V indicates power switch OFF or defective, or a wiring or connector problem. 2. Voltage betwee

E. GRID ASSEMBLY 1. Turn and position the grids so that the waffle-sides are facing each other. Thread the hi-temp tubing thru the shaft of the pivot housing. Attach the pivot housing to the bottom grid with screws (bottom hole) and screws with washers (middle hole). Use anti-sieze paste on the screw threads, but do not tighten the screws yet. 2. Insert the pivot shaft thru the pivot housing and top grid, making sure wires 5, 6 & 20 are routed between the pivot shaft and the body of

F. PIVOT BEARING ASSEMBLY The pivot bearing may be out of alignment as it comes from the box. Tap the collar of the bearing 1. with a plastic hammer until the axis of the bearing is perpendicular to the base. Attach the pivot bearing to the inside of the cabinet. The zerk fitting points downward. Use Loctite on the threads. 2. Looking into the back panel, turn the bearing until the set screws are at the 10:00 and 2:00 position. Assemble the actuator to the pivot bearing. The set
