Introduction
The HOTROD has been designed for quiet efficient cooking of frankfurters and sausages in minimal space. The unique drive
mechanism, which allows full tube rotation, ensures uniform cooking and has few moving parts. Independent front/rear temperature
controls permit fast cooking and gentle warming at the same time. An optional sneeze guard is available.

Equipment Set Up
Installation
Place the HOTROD directly on a counter top or on a BW20/40 bun warmer (available separately). Locate the unit as close to an AC
outlet as possible, to avoid undue strain on the power cord.
CAUTION: To avoid equipment damage, make certain the nameplate voltage is the same as the outlet voltage. Before using the
HOTROD for the first time, wipe the rollers and the drip pan with a damp cloth.
Operation
There are 3 simple controls on the front of this unit: a toggle switch (which controls tube rotation) and 2 adjustable heat switches
with matching indicator lights (the FRONT control on the left adjusts the temperature of the first 5 tubes, while the REAR control on
the right adjusts the last 6). The table below shows the average tube temperature for each number on the heat switches. This
information is presented as a guide only; exact adjustment should be based on personal as well as customer preference. Variations
in local conditions may also cause actual temperatures to differ from those shown.

WARNING
This Hot Dog Grill is not intended
to hold potentially hazardous
foods, such as uncooked and
unpreserved meats and
sausages.

Cleaning Procedure
Clean the grill during slow periods as well as at the end of each day. To do so:
1. Turn both heat controls to 3 and the toggle switch to ON so the rollers turn.
2. When the roller tubes become hot, turn off the heat and allow them to cool until they are still warm but not enough to burn your
fingers.
3. Using a moist cloth and crushed or flaked ice, wipe each tube from end to end, extending the cloth as far as possible between
the rollers.
4. If stains are still present, add a light detergent to the cloth and repeat.
CAUTION: Avoid the use of abrasive powders or pads, as the finish may be damaged.
5. Remove the drip pan and wash it in hot soapy water; rinse.
6. Replace the pan; turn the unit off if grill will not immediately be used.
NOTE: Cleanup will be faster if the product is specifically made for cooking on roller grills. Several meat packers now offer this
product.
Nonscheduled Maintenance
Under normal circumstances, with reasonable care and periodic cleaning, the HOTROD should require little non-scheduled
maintenance. All routine repairs should be performed by personnel with extensive service experience.
However, the grease seal may require periodic replacement. The grease seal is held on the tube by friction and must be stretched
before it can be installed. A Grease Seal Expander Kit (part no. 4469) may be ordered from your distributor.
Troubleshooting
To use this troubleshooting guide, you should (1) accurately identify the problem. (2) determine the cause of the problem, and (3)
carry out the corrective action to repair the unit. This guide may not address all possible problem situations. If you cannot correct a
problem, contact your service representative.
WARNING: This unit operates on either 120 or 220 volts, depending on the model. DO NOT attempt any electrical repairs unless
you are qualified to do so and have the proper diagnostic equipment. Never perform electrical repairs when the unit is connected to
the AC line. When in doubt, call your service representative.
