OPERATIONAL CHECKS A. TEMPERATURE CHECK CAUTION: 1. Desired baking temperature is 390ºF ±5º (200ºC ±3º) ELECTRIC SHOCK HAZARD 2. Turn power switch ON and allow waffle baker to heat for a minimum of 30 minutes. Insert a pyrometer of known accuracy between the closed grid plates and allow the reading to stabilize. 3. Temperature controller is located behind the back panel. Remove the back panel to access. Turn the temperature controller dial clockwise to increase; counter-clockwise to decrease.
OPERATIONAL CHECKS (continued) ELECTRIC SHOCK HAZARD Live electric circuits may be exposed during these procedures. Take necessary precautions to avoid electric shock. CAUTION: BURN HAZARD HOT SURFACES Equipment surfaces may be hot during these procedures. Take necessary precautions to avoid burns. 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.
SERVICING INSTRUCTIONS A. CABINET ASSEMBLY CAUTION: 1. Insert the trademark plate from the front. From the rear of the cabinet, slide retainers over the trademark plate pins. Using a deep socket, tap the retainers down until they are flush with the cabinet surface. 2. Attach wires 1, 2, 3 & 4 to the power switch switch. Thread one nut onto the switch shaft approximately 1/2”, then slide the switch seal over the switch shaft. Insert the switch from the rear of the cabinet.
SERVICING INSTRUCTIONS (continued) CAUTION: B. BACK PANEL & SOLID STATE CONTROLS ASSEMBLY ELECTRIC SHOCK HAZARD 1. Apply foam tape to the back panel flange - inside surfaces for the right, left and bottom; outside surface for the top. Unplug appliance from electric power before removing any panel or access cover. 2. Insert the power cord into the strain relief, then install the strain relief from the outside of the back panel. 3.
SERVICING INSTRUCTIONS (continued) C. TOP GRID CAUTION: 1. Prepare grid casting by applying a small amount of anti-sieze paste to all threaded holes. ELECTRIC SHOCK HAZARD 2. Feed wires 5, 6 & 20 thru the right feed-thru hole. Attach wires 5 & 6 to the element terminals. Attach wire 20 to the center-most boss at the front of the casting. 3. Pull the wires back until they have only a small amount of slack. Seal both sides of both feed-thru holes with hi-temperature silicone sealant.
SERVICING INSTRUCTIONS (continued) CAUTION: E. GRID ASSEMBLY ELECTRIC SHOCK HAZARD 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. Unplug appliance from electric power before removing any panel or access cover. 2.
SERVICING INSTRUCTIONS (continued) F. PIVOT BEARING ASSEMBLY CAUTION: 1. The pivot bearing may be out of alignment as it comes from the box. Tap the collar of the bearing 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. ELECTRIC SHOCK HAZARD Unplug appliance from electric power before removing any panel or access cover. 2.
SERVICING INSTRUCTIONS (continued) CAUTION: G. BYPASS HI-LIMIT THERMOSTAT ELECTRIC SHOCK HAZARD 1. The hi-limit thermostat in this Belgian Waffle Baker has been found to be unnecessary. Wells BWB-1S has been tested and approved by UL for use without the hi-limit thermosat. Unplug appliance from electric power before removing any panel or access cover. 2. All units requiring service, whether in or out of warranty, should have the hi-limit thermostat bypassed. 3.
