IMPORTANT
A.J. Antunes & Co. reserves the right
to change specifications and product
design without notice. Such revisions do
not entitle the buyer to corresponding

GENERAL
The Muffin Toaster Model MT-12 is designed
to toast 6 full English muffins (12 halves) at
one time. A temperature sensing solid state
control measures the internal temperature
of the toaster and adjusts the toasting time
automatically to toast muffins faster during
heavier use. The toaster signals the operator
with an audible beep and a ready light when
muffins are ready.
The toaster is capable of producing up to 324
muffins per hour. 6 muffin halves or less is a
partial load and 7 - 12 muffin halves is a full
load.
To conserve energy, when the toasting chamber is empty, the toaster idles at 600 watts.
This represents a 75% reduction in operational power consumption.
This manual provides the safety, installation,
and operating procedures for the unit. We
recommend that all information contained in
this manual be read prior to installation and
operation.
This unit is manufactured from the finest
materials available and is assembled to
Roundup’s strict quality standards. It has
been tested at the factory to ensure dependable trouble-free operation.
