3. VERTICAL TOASTER OPERATIONAL DESCRIPTION

The Vertical Toaster is designed to produce fresh, uniformly toasted buns on an "as needed” basis.
The countertop-mounted unit consists of a cabinet, a computer, a heating element and a pair of
conveyor assemblies.

When the unit is turned on, an electrical heating element (called a platen) is energized. The platen
heats up to a programmed temperature referred to as the setpoint. At the same time, both conveyor
assemblies are activated. When a bun is placed into one of the slots at the top of the cabinet, the
conveyor belts gently carry it through the unit, with the cut face of the bun passing over the heated
platen. As the bun passes over the platen, it is toasted. At the end of the process, the bun is deposited
onto a heated holding tray that keeps it warm until it is used in a sandwich.

The computer allows the operator to adjust the setpoint to obtain desired toasting characteristics.
Compression adjustment knobs also allow the operator to adjust the compression of heels and crowns
as they pass through the toaster.

4. INSTALLATION/SETUP

Upon arrival, inspect the toaster for concealed damage. Immediately report any damage to the
delivering freight company. Claims must be filed within 15 days after receipt of the unit.

Power Requirements:

ALL ELECTRICALLY OPERATED APPLIANCES MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES, OR

PLUGGED INTO A PROPERLY GROUNDED RECEPTACLE. DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG!

IN THE ABSENCE OF LOCAL CODES, WITH THE NATIONAL ELECTRICAL CODE (ANSI/NFPA NO. 70-1990) OR THE

CORRESPONDING NATIONAL CODE OF THE COUNTRY IN WHICH INSTALLED.

THIS APPLIANCE IS EQUIPPED WITH A GROUNDING PLUG FOR YOUR PROTECTION AGAINST SHOCK HAZARD AND MUST BE

• Voltage: 208VAC or 240VAC depending on model ordered

• Frequency: 60 Hz (non-CE )or 50 Hz (CE and Australian models)

• Phase: Single

• Service: 20 Amp

Setup:

Setup of the toaster consists of unpacking the unit, placing it on a sturdy table or countertop adjacent to
a properly grounded AC outlet of appropriate voltage, removing the cardboard packing inserts, installing
the bun feeder in the slot on top of the cover, and plugging it in. NOTE: The cover must be closed to
install the bun feeder, and the bun feeder must be removed to open the cover.

The unit is shipped with a programmed setpoint of 550°F (288°C), upper crown compression knob set
to 4, lower crown compression knob set to 5, upper heel compression knob set to D, and lower
compression knob set to E. The operator may change these settings to attain desired toasting.

5. OPERATION

1. Press the ON/OFF button. The word LOW will appear in the green LED display window. The

unit will take about 10 minutes to reach operating temperature, at which time the display will change

to REDY, indicating the toaster is ready for use.

2. Load buns into the appropriate slots (Heel or Crown) one at a time, with the cut faces toward the
rear of the unit. The unit will toast the buns and transfer them to the heated holding tray.

3. Adjust the setpoint and bun compression as necessary to achieve desired toasting.

6. VIEWING AND ADJUSTING THE SETPOINT

To view the platen temperature, press the button once. The temperature in degrees Fahrenheit will
appear in the green LED display window. To view the current setpoint, press the
setpoint in degrees Fahrenheit will be displayed in the green LED display window. To toggle the
display to Celsius, unplug the unit, then press and hold the

button as the unit is plugged back in.

To change the setpoint:

button twice. The

1. Turn the unit OFF (press the

button once. Press the ON/OFF button. If

the platen is within 20°F (11°C) of the setpoint, the display will show REDY. Otherwise, the display
will show LOW or HIGH until the platen is within 20°F (11°C) of the setpoint, at which time the
display will change to REDY.

7. ADJUSTING BUN COMPRESSION

1. There are two pairs of compression adjustment knobs (one pair numbered 1-5, the other lettered A­E), as shown in the accompanying illustration. Factory settings are circled.

A separate set of Maintenance Requirement Cards (MRCs) is furnished with this manual. In addition to the
checks and services contained in the MRCs, Frymaster recommends that this appliance be inspected by a
Frymaster Factory Authorized Service Technician at least annually as follows:

• Inspect all wiring for signs of chafing, kinking, and/or loose connections.

• Verify that all mechanical and electronic components are securely mounted (i.e., screws and nuts and bolts are

tight.)

• Verify that idler roller springs are in serviceable condition (i.e., rollers are held securely in the top of the
J-slots and belts do not slip).

11. SERVICE INFORMATION

11.1 INTRODUCTION

Vertical toasters manufactured for use in the European Union (CE) and those manufactured for use
elsewhere are identical in most respects, but there are some important differences. The paragraphs
that follow summarize the differences and provide a list of the parts that are unique to each model.

The most significant differences are in the electronic components. Units built for the CE and Australian
markets have a 50 Hz motor; all others have a 60 Hz motor. Non-CE and CE/Australian units also use
different transformers, and CE/Australian units have a line filter built into the electrical power supply
system. The line filter and cover are attached to the rear of the cabinet.

Because of the difference in the power cycle frequency (50 Hz vs. 60 Hz), CE and Australian units are
equipped with 10-tooth drive pulleys and a 28-Tooth motor pulley. Standard units have 17-tooth drive
pulleys and an 18-tooth motor pulley. The different pulleys on the CE and Australian units maintain the
correct belt speed even though the RPM of the motor at 50 Hz is slightly slower than that of the motor
at 60 Hz.

The table below identifies the components that are unique to each configuration.
