unit:
• Read all instructions before using equipment.
• For your safety, the equipment is furnished with
a properly grounded cord connector. Do NOT
attempt to defeat the grounded connector.
• Install or locate the equipment only for its intend-
ed use as described in this manual. Do NOT use
corrosive chemicals in this equipment.
• Do NOT operate this equipment if it has a dam-
aged cord or plug, if it is not working properly, or

• The toaster should be grounded according to
local electrical codes to prevent the possibil-
ity of electrical shock. It requires a grounded
receptacle with separate electrical lines pro-
tected by fuses or a circuit breaker of the
proper rating.
• Bread may burn. Therefore toasters must
NOT be used near or below curtains or other
combustible walls and materials. Failure to
maintain safe operating distances may cause
discoloration or combustion.
• When installing a Conveyor Belt Wrap, be
careful NOT to wrap it over the Upper and
Lower Support Rods or permanent damage to
belt will occur. Make sure Belt Wrap is posi-
tioned inside the Upper and Lower Support
Rods.
• Make sure both ends of the Belt Wrap are
aligned evenly before installing Belt Wrap Pin.
• Failure to use Release Sheets may result in
damage to the equipment and loss of war-
ranty coverage.
• Do NOT clean this appliance with a water jet.
• If supply cord is damaged, it must be replaced
by the manufacturer, its service agent, or a
similarly qualified person.
• All electrical connections must be in accor-
dance with local electrical codes and any
other applicable codes.
• WARNING, ELECTRICAL SHOCK HAZARD.

OPERATION
Figure 3. Bun Thickness Adjustment Controls
(Default settings circled)
Operating Instructions
1. Set the Bun Thickness Adjustment Controls
(Figure 3) to desired setting.
NOTE: Recommended settings are 4 for Heels and
F for Crowns.
2. Turn the power on and allow the toaster to warm
up for 30 minutes before proceeding.
NOTE: The temperature display (Figure 2) will flash
“LO” until the toaster reaches its preset operating
temperature. When the toaster approaches the pre-
set temperature of 600°F (316°C), “USE” appears
in the temperature display and the unit is ready to
toast buns. If “USE” does not appear in the win-
dow after approximately 30 minutes, contact your
Authorized Service Agency.
3. Drop Crowns and Heels into the slot (Figure 2).
NOTE: Cut sides of Heels and Crowns must face
each other.
4. Toasted buns will drop into the Bun Landing Area
(Figure 2) in approximately 10 seconds.
5. Test at least four buns before putting the toaster
into service.
6. Turn the power off when finished toasting for the
day and proceed with the Daily Cleaning as out-
lined in the Maintenance section of this manual.
Temperature Adjustments
The VCT-2000 uses a Platen Heater and two Auxiliary
Air Heaters. The Platen Heater consists of a heating
element built into the Platen to toast the cut side of the
bun. The two Auxiliary Heaters assist in providing addi-
tional heat to the buns. The first Auxiliary Air Heater is
located between the conveyor in the front of the toast-
er. The second Auxiliary Heater is located between the
conveyor at the rear of the unit.
RECOMMENDED TEMPERATURES
Recommended temperature setting for the Platen
heater is 530°F (277°C).
Recommended temperature setting for the Auxiliary Air
Heaters is 400°F (204°C).
NOTE: The toaster is tested and shipped with the
heaters set at the above recommended temperatures.

Chains.
MEASURING CONVEYOR BELT CHAINS
1. Turn the unit off, unplug the power cord, and
allow the unit to cool.
2. Remove the Bun Feeder, Butter Wheel, Pan, and
Heat Shield (Figure 1) and set the Bun Thickness
Compression Knobs to 6 & F.
3. Open both Conveyor Covers and pull the Belt
Wrap Pin out of the zipper (Figure 6).
4. Remove the Belt Wrap.
5. Facing the toaster, locate the approximate center-
point of the Conveyor Chain.
6. Pull the Conveyor Chain away from the edge of
the toaster (Figure 9).
7. Stand a U.S. Dime on end between the frame
and the chain (Figure 9).
8. If the gap is significantly wider than the coin,
REMOVE links as described below.
9. Disconnect the Conveyor Belt Chain by squeez-
ing any two links together and unhooking both
ends one link (Figure 10). Needle-nose pliers
may be used.
NOTE: There are two small 1/2” links on each side
of the Conveyor Belt Chain. The rest are large 3/4”
links.
10. Remove one 1/2” link from the belt.
11. Reassemble the Conveyor Belt Chain onto the
sprockets as described in Replacing Conveyor
Belt Chains.
12. Measure the gap again to ensure it is not too
tight.
13. Check the opposite side of the toaster using the
same steps.
NOTE: If the Conveyor Belt Chain is too tight to be
reassembled, remove an additional small 1/2” link
and install a large 3/4” link in its place. This will
increase the length of the Conveyor Belt Chain by
1/4” overall.
REPLACING CONVEYOR BELT CHAINS
1. Turn the power off, unplug the power cord, and
allow the unit to cool.
2. Remove the Butter Wheel, Pan, and Heat Shield
and set the Compression Control Knobs to 6 & F.
3. Open both Conveyor Covers and pull the Belt
Wrap Pin out of the zipper.
4. Remove and discard the old Belt Wrap(s).
5. Disconnect the Conveyor Belt Chain by squeezing
any two links together and unhooking both ends
of one link (Figure 10).
6. Place the replacement Conveyor Belt Chain on
the top sprockets with hook ends down.
NOTE: The ends of the hooks must point down
(Figure 10).
7. Wrap the Conveyor Belt Chain around the top
and lower sprockets and connect by hooking both
ends together.
NOTE: Make sure the Conveyor Belt Chain is
installed between the Upper Support Rod and the
Lower Support Rod.
