3. Set both compression knobs to: 6 = 7/8” (22.2
mm).
4. Disconnect the conveyor belt by squeezing any
two links together and unhooking both ends of
one link (Figure 8). A needle-nose pliers may be
required. Remove conveyor belt.
NOTE: With conveyor belt removed, the tensioner
assemblies (4, page 24) and slide rails (40, page 24)
can be replaced.
Maintenance Schedule
DAILY
1. Turn off power to the toaster.
2. When the toaster is cool, follow the procedures
under Cleaning the Release Sheet.
3. Remove heat shield and bun chute. Wash in
back sink, sanitize and rinse.
4. Wipe down the outside of the toaster with a
slightly damp cloth and allow to air dry.
Cleaning the Release Sheet
1. Turn the rocker switch to off, unplug the unit and
allow it to cool down.
2. Put on protective gloves. Remove heat shield
and release sheet (Figure 7).
3. Wipe release sheet on both sides with a clean,
sanitized towel.
4. Remove front and rear conveyor cover assys.
(Figure 4). Wipe exterior of conveyor belt with a
clean, sanitized towel.
5. Install front and rear cover assys. (Figure 4) then
turn toaster on. Count to 10, then turn toaster off.
Remove front and rear cover assys. and wipe
new section of belt. Re-install the front and rear
cover assemblies.
6. Install the release sheet by draping it over both
sides of the platen with the crease centered
directly on the platen (Figure 7).
7. Install the heat shield (Figure 7). The heat shield
clips fit over the tip of the platen and retain the
release sheet.
IMPORTANT: Make sure heat shield assy. is activat-
ing (depressing) the conveyor interlock switch (see
Figure 7). The conveyors will not rotate unless the
heat shield is in place and interlock switch is acti-
vated (depressed).

SERVICING CONVEYOR BELTS
After a period of time, the conveyor belt links will wear
and the conveyor belt will stretch. This will eventually
cause the conveyor to jam as it rotates on the sprock-
ets. This is easily remedied by removing one or more
conveyor links from each side of the belt.
There are four 1/2” pitch links on each conveyor belt.
The rest of the links are 3/4”.
1. Remove conveyor belt as described previously on
page 10.
2. To shorten a stretched conveyor belt, remove one
1/2” link from the belt.
3. Reassemble the belt to the sprockets as
described below.
NOTE: If the belt is too short (tight) to be reas-
sembled, remove an additional 1/2” link and install
a 3/4” link. This will make the conveyor belt 1/4”
shorter and enable it to be reassembled.
IMPORTANT: This is not covered under warranty.
It is a user responsibility.
REPLACING CONVEYOR BELTS
1. Remove old conveyor belt as described previ-
ously on page 10.
2. Place replacement conveyor belt on top sprock-
ets. Check for correct positioning (Figure 8).
NOTE: Install conveyor belt so that the ends of the
hooks are facing down.
3. Wrap conveyor belt around lower sprockets and
connect by hooking both ends of the belt back
together. A needle-nose pliers may be required.
4. Re-intall front and rear conveyor covers, release
sheet and heat shield.
Replacing Spring Tensioners
1. Remove acorn nuts (Figure 9).
2. Remove old spring tensioner assy.
3. Replace tensioner assy. and reassemble.

4. Make sure the spacers are placed inside the
tensioner arm. The spacers are smaller than the
holes to allow the tensioner to pivot freely.
Replacing Conveyor Motor and Fan Blade
NOTE: A small amount of Loctite (Blue & Red) is
required for proper gear motor installation.
1. Remove control cover.
2. Disconnect the motor wires and remove the
drive motor and drive motor bracket (Figure
10). Discard the 8-32 x 5/16” mounting bracket
screws.
3. Remove the motor sprocket using a hex wrench.
4. Remove the drive motor bracket from the gear
motor. Save the four 10-32 x 3/8” pan head
screws (P/N 310P154).
5. Place one drop of Loctite (Blue) into each thread-
ed hole in the gear reducer casting. Attach the
drive motor bracket to the gear reducer using
the original four 10-32 x 3/8” screws (310P154)
removed in step 3.
6. Attach the motor sprocket to the gear reducer as
shown in Figure 10.
NOTE: Be sure sprocket setscrew is positioned
on the flat of the gear reducer shaft. Maintain the
3/16” dimension as shown in Figure 11. Apply
Loctite (Blue) to threads of setscrew and tighten
securely.
7. Using the four new 8-32 x 5/16” stainless steel
SEMS truss head screws (P/N 308P151), attach
the drive motor bracket to the mounting bracket.
DO NOT tighten screws at this time.
8. Place the drive chain on the sprocket and push
down on motor. Allow 1/4” (0.6 mm) play at mid-
dle of drive chain, then tighten mounting screws
while holding motor. Check drive chain play after
tightening screws.
9. Re-connect motor wires, one at a time.
10. Re-install control cover.
Apply only 1 drop of Loctite (RED) to front of fan assy. after
assembly. Outer edge of fan blade hub to be flush with end of
motor shaft.

TROUBLESHOOTING
WARNING
To avoid possible personal injury and/or damage to the unit, inspection, test and repair of electrical equip-
ment should be performed by qualified service personnel. The unit should be unplugged when servicing,
except when electrical tests are required. Use extreme care during electrical circuit tests. Live circuits will
be exposed.
Problem Possible Cause Corrective Action
No heat and conveyor
belts do not move.
Toaster is installed incor-
rectly.
Perform installation and operating procedures
(pages 7-9).
Not enough voltage, defec-
tive power cord, defective
rocker switch.
Check receptacle for correct voltage. See
Specifications (page 5).
With unit plugged in and rocker switch on, check
for correct voltage into rocker switch. If low or zero
voltage, replace power cord. If voltage is correct,
check for correct voltage out of rocker switch. If low
or no voltage, replace rocker switch.
Hi-limit switch tripped open. Reset hi-limit switch (Fig. 5, page 9).
Wiring problem. Check all electrical connections for burns, discolor-
ation or arcing. Replace all connections or compo-
nents with damaged terminals. Replace all dam-
aged wiring with the same (or higher) rated wire.
No heat and conveyor
belts move.
Wiring problem. Check all electrical connections for burns, discolor-
ation or arcing. Replace all connections or compo-
nents with damaged terminals. Replace all dam-
aged wiring with the same (or higher) rated wire.
Inoperative platen. To check platen:
Use an Ohm meter to test resistance of the platen
heater (disconnect 1 wire to isolate heater). Correct
cold resistance for heating element of platen are as
follows:
120 Volts, 1750 Watts - 7.8 Ohms
208 Volts, 2550 Watts - 16.2 Ohms
230 Volts, 1900 Watts - 26.5 Ohms
VCT-20 only. The auxiliary heaters are 144.2 Ohms
at 208V/300 Watts.

Platen is hot and conveyor belts
do not move.
Toaster is installed incor-
rectly.
Perform installation and operating proce-
dures (pages 7-8).
Wiring problems. Check all electrical connections for burns,
discoloration or arcing. Replace all connec-
tions or components with damaged terminals.
Replace all damaged wiring with the same
(or higher) rated wire.
Drive motor inoperable or
incorrect conveyor drive
motor.
To check drive motor:
1. Measure resistance of motor coil. Replace
motor if coil measures either open circuit
or zero resistance.
2. Mark the drive motor sprocket and count
the turns per minute. Correct drive motor
speed is nine (9) turns per minute for VCT-
20; three (3) turns per minute for VCT-25;
one (1) turn per minute for VCT-50.
Broken drive chain or loose
sprocket.
Check drive chain for kinks, broken or bent
links or other damage. Check motor sprocket
and drive sprockets (on drive shaft); tighten
setscrew on flat of shaft if required. Check
for damaged/worn sprockets and replace as
required.
Heat shield. not installed. Install heat shield.
Conveyor belts installed
incorrectly.
Install conveyor belt to match diagram in Fig.
8 (page 11). Be sure that ends of the hooks
are facing down.
Conveyor interlock switch
not depressed.
Install heat shield. correctly.
Spring tensioner assy. or
tensioner bent or missing.
Replace spring tensioner assy(s). (29, page
22) or tensioners (4, page 24) if damaged or
loose.
Replace slide rails (40, page 24) if worn or
missing.
Conveyor belt too loose
or missing links (41 links
required when new). When
new, conveyor has 37 large
links and 4 small links.
Remove conveyor belt (page 11). Lay belt
flat and count links. Replace entire belt if
links are damaged. If conveyor belt has too
much play, it will jam. Adjust belt length as
described under Servicing Conveyor Belts
(page 11).
