Fixture or top must be sufficiently rigid to support device weight without warping. Emphasis is on simplifying the layout and fabrication. These instructions covers all models. The floor plans for the griddles shows overall and other key dimensions of the device and their relationships to the fixture or top into which they will be installed. U.L.CONDITIONS OF ACCEPTABILITY: A. This equipment must be installed in an all metal fixture of steel or stainless steel construction, .078 inch thick minimum for the top and supporting frame. Side enclosure to be at least 22 MSG minimum thickness. B. A removable bottom enclosure must be provided under each drop-in unit and be made of metal construction of at least 22 MSG min. If ventilating openings are provided in the bottom enclosure they must not allow the entrance of a 3/4 inch diameter rod nor be located directly below uninsulated live terminals. C. Minimum spacing between griddle top edge and adjacent items should be: fixture back wall 1-3/4 inch, Fixture side enclosure 1 inch, Front control panel 7/8 inch, Otherdrop-in devices 1 inch. D. Controls shall be mounted on the front vertical surface of the fixture. E. For supply connections use wire suitable for at least 90 degrees Celsius (194 degrees Fahrenheit). LAYOUT 1. The layouts illustrate the holes to be cut into the metal fixture or fabricated top to accept the griddle. Also shown are holes to be cut into the fixture front (apron) to accommodate the griddle control panel. The front-to-back (depth) dimensions for the griddles are not the same. Before making the initial cuts into the fixture, make sure that the model number you are referring to corresponds with the model numberon the griddle nameplate. 2. All minimum dimensions shown must be met. 3. After making the proper layout, cut the hole in the top of the fixture. 4. Cut the large hole and drill the control panel holes in the front of the fixture from the layout. 5. The griddle is furnished with a stiffening angle or reinforcement frame assembly that is used to reinforce the fixture top. This reinforcement must be welded on the perimeter of the counter top cutout. The upturned flanges on the reinforcement should be located an equal distance from the sides of the cut-out. Figure #2 shows a cutaway view of how the stiffening angle appears when welded to the fixture top. NOTE: (1) Before welding the stiffening angle to the fixture top, assemble the furnished clamps and clamp screws as shown in figure #2. (2) Place one clamp in each of the frame assembly slots. Do not tighten the screw. INSTALLATION With all the large holes cut out, the smaller control panel holes drilled, and the stiffening angle welded into place, the fixture is now ready to receive the griddle. 13 CIS*I IDC O 6. 7. 8. 9. Hobart furnishes a gasket or seal that must be placed around the perimeter of the hole in the top as shown in Fig. 3. This gasket may be temporarily held in place with tape. Do not place the staple securing the gasket ends on or near a corner. A number of clamps, such as the one shown in Fig. 3, appear at intervals along the perimeter. Pull clamps outward so that the griddle frame clears them when it is dropped into place. Drop the griddle into position by lowering it into the fixture top hole. Make sure that the thermostat capillaries are not kinked or pinched when setting the griddle in place. With the griddle in place, the gasket or seal becomes compressed. See Fig. 4. Slide the clamp inward so that it engages the upper part of the protruding angle from the griddle body frame. See Fig. 5. Slide the clamp sideways so that the notch on it locks against the reinforcement angle. This prevents the clamp from sliding out. Tighten the clamp screws against the angle as shown in Fig. 5. This tightening forces the clamp to press down on the griddle body frame extension. The ...
