OPERATION

WARNING: THE BROILER AND ITS PARTS ARE HOT. BE CAREFUL WHEN OPERATING, CLEANING OR SERVICING THE BROILER.

CONTROLS
Broiler
Infinite Load Switches	— Two switches independently control the front and rear heating elements
	in 208 and 240 volt models. The switch located on the left-hand side
	of the switch panel controls the percent on-time of the two front
	elements, and the switch located on the right-hand side of the switch
	panel controls the two rear elements. The percent on-time of the
	infinite load control varies from approximately 10% in the VERY LOW
	position to 100% in the HIGH position.
3-Heat, 4-Position Switch	— On 480 volt models, each of the two non-cycling 3-heat, 4-position
	switches control independently the front and rear sections of the
	broiler. Input varies from full power at the HIGH position (both
	elements connected in parallel) to MED position (one element only
	on) to LO position (both elements connected in series).
Grid Handle	— The distance of the grid surface from the elements is controlled by the
	pull-and-release grid handle at the right of the broiler. This grid handle
	locks in 13 positions over the 6" (152 mm) grid travel.

The operator can, by independent setting of each switch, provide a wide range of broiler temperatures depending on the type and location of the broiling product.

Oven
3-Heat Switches	—	Two switches (located on the right side of the switch panel, on each
		side of the thermostat) independently control the top and bottom
		heating elements. At HIGH position, the maximum element power
		is utilized (elements connected in parallel); at MED position, only one
		of the two elements is on (about 1/2 power); at LO position, the two
		elements are connected in series (about 1/4 power); at the OFF
		position, both elements are completely turned off.
Thermostat	—	Controls the temperature of the oven from 175°F to 550°F (79°C to
		288°C).
Indicator Light	—	(Mounted next to the thermostat.) When lit, the thermostat is calling
		for heat, and when off, indicates the desired temperature is
		reached.
