TECHNICAL THEORY OF OPERATION
Hot Dog Corral Technical Theory of
Operation
When the Rocker Switch (power On/Off) is ON, voltage
flows to the capillary bulb Thermostat(s), Drive Motor
Assembly, and to the Digital Timer.
**
NOTE: HDC-20 units consist of a single ther-
mostat that controls the entire grill area tem-
perature. HDC21A/30A/35A/50A units consist of
2 Thermostats. The upper Thermostat controls
the upper grill area temperature and the lower
Thermostat controls the lower grill area tempera-
ture.
Provided that the grill area temperature is below the
Thermostat setting, the Thermostat calls for heat by
supplying line voltage to the Heating Element.
NOTE: The Heating Element(s) are secured to the
under-side of the grill area.
As the grill area begins to heat up, the Thermostat’s
bulb (mounted near the Heating Element) monitors the
grill area temperature. Once the grill area temperature
approaches the Thermostat setting, the Thermostat’s
contacts open and the Heating Element stops heating.
The heating circuit(s) will cycle on and off as needed,
even at idle. The hot dogs are placed between the
Roller Rods of the sliding Driver Frame Assembly. As
the Drive Motor runs, it operates a linkage system
which, in turn, operates the Driver Frame Assembly by
moving it up and down.
As the hot dogs roll, they absorb the heat from the grill
surface area.
NOTE: The Driver Frames used in HDC-20/30A/50A
units slide on four replaceable Nylon Glides that
are pressed into the corners on the unit. The Driver
Frames used in HDC-21A/35A units integrate four
replaceable Nylon Glides with Retainers. The glides
help prevent the Driver Frame from scratching the
Grill area.
** The Digital Timer is used only on some mod-
els. The customer can program the timer up to 15
minutes. It is used to monitor the product cooking/
heating time. An integrated audio signal will sound
for a few seconds at the end of a timed cycle.
