RT-2AR Service Manual

BEFORE INSTALLATION

The RT-2AR should be placed in the most convenient location for ease of cleaning, maintenance, service and
general operation. Careful consideration should be given to avoid drafts, close proximity to grease or vapor-
producing appliances or other high ambient heat equipment. A minimum of ½” clearance is required for air
circulation. This is assured by the rounded “acorn” nuts protruding from the sides and rear of the unit. Overhead
clearance from the top of the toaster should be as much as possible and sufficient to allow heat dissipation.

the old style assembly, which included a resistor and/or P.C. board, do the following: The gear motor, which
has 2 black wires, one is plugged into the white side of the terminal block, and the other one is spliced together
with the black wire off the Conveyor Speed Control POT. Then the blue wire off the Conveyor Speed Control
POT is attached to the On/Off Switch.
