SAFETY PRECAUTIONS
APW Wyott toasters are designed, built and sold for commercial use and should be operated by trained personal only. Make
sure all CAUTIONS, WARNINGS and operating instructions are clearly posted near each unit to insure proper operation and
reduce the chance of personal injury and/or equipment damage.
Always disconnect power before cleaning or servicing the toaster. Surfaces will remain hot after power has been removed,
allow unit to cool before cleaning or servicing. Never clean the toaster by immersing it in water. The toaster is not protected
against water jets; DO NOT CLEAN TOASTER WITH A WATER JET. Always clean equipment before first use.
Operating toaster without legs will void the warranty. Insure all accessories and exterior panels are properly installed and
adjusted before applying power and operating.

INSTALLATION
1. Unpack Unit
Remove unit from shipping carton, unwrap loose parts and remove any packing tape, plastic wrap and nylon tie-down.
Account for the following parts:
Legs
Shipped (4) in plastic bag
Butter roller & Pan (optional)
In individual carton
Conveyor
In individual carton
Feeder/Bun Chute
Wrapped, loose in top of carton
Instruction Manual
Loose in carton
Teflon Sheet Kit (optional)
Loose in carton
NOTE: Prior to initial start-up, all removable parts and the grill surface should be cleaned with warm soapy water to remove
manufacturing oils, then rinsed and dried thoroughly. Apply oil to the conveyor chain after washing. Also, for wet operation the
grill surface should be seasoned with a light coating of oil (fry oil works well) and preheated for 15-20 minutes.
2. Assemble Legs
Lay the toaster on its side and install the four adjustable legs into the threaded holes on the bottom of the toaster sides. Hand
tighten the legs by gripping the black shank and turning until it is seated firmly against the bottom of the side. Set the toaster
upright. The unit may be leveled by unscrewing the lower, chrome insert of each leg. Flats are provided on two sides of the
insert to allow use of a wrench. “Precise” leveling is not required for proper operation.
3. Conveyor Installation
The conveyor is shipped in an individual carton. Unpack the conveyor and clean and lubricate as noted.
Remove the top front panel by lifting it straight up. The bottom front panel can now be removed by lifting it straight up to
disengage the pins and rod.
Lift conveyor using “U” shaped handles on each conveyor side bracket and lower it into the two hanger brackets above the
grill plate on each side, so the four spacers on the sides of the conveyor rest on the bottom flange and the bottom spacers are
against the adjustment screws. The hanger brackets are factory adjusted. However, before reinstalling the front panels apply
power to the unit and run the conveyor to insure proper gear engagement. If gears are not properly engaged adjust the
conveyor by loosening the jam nuts on the hanger brackets and adjusting the conveyor to the correct height. Retighten jam
nuts after adjustment is complete. Reinstall front panel.

4. Feeder/Bun Chute Assembly
Install Feeder/Bun Chute by fitting slots on back of feeder onto back panel studs located at top rear of unit.
5. Butter Pan & Roller (Optional)
Install pan on the shelf on the top of the bottom front panel. Notches on the back splash will fit below the drive collet and the
left side bearing. Install roller in pan by fitting slotted shaft into drive collet so slot aligns with pin through drive collet. Solid end
of shaft will lay in the left side bearing.
6. Install Teflon Sheet (Optional)
Remove Feeder/Bun Chute. Allow one end of the Teflon sheet to overlap the top of the rear panel to the rear studs. Balance
of the sheet will fit over the grille surface. Reinstall Feeder/Bun Chute capturing Teflon Sheet.
LOCATION
Place the toaster on a flat surface. This toaster is tested and approved for zero clearances. Locate the toaster near a wall
receptacle of the proper configuration. DO NOT USE AN EXTENSION CORD. Plug the power cord into an outlet (receptacle)
of the specified voltage on the rating label. Outlets must be properly grounded.

OPERATING INSTRUCTIONS
1. Turn Main Power Switch on. Set Temperature Control knob to desired temperature. Allow Pilot Light to cycle at least two
times (on/off). When light is on grill is heating. When light is off the grill is off. Time to heat up is about 15-20 minutes.
2. If toasting dry (without oil) insure Teflon sheet is properly installed. Turn motor switch on, conveyor should start to turn.
Place bun halves on feeder cut side down (facing grill surface). Toast time is approximately 14 sec. depending on bun height
and diameter. Increase or decrease temperature setting to achieve desired brownness and temperature.
When toasting using oil, any high-quality cooking oil may be used with this toaster (do not use oils that contain dairy
products such as butter). The Teflon sheet may be used, but is not required. Fill the butter roller 2/3 full of warmed cooking oil.
The oil should spread evenly over the surface of the roller. Holding the bun half in the palm of the hand, slap the cut surface of
the bun on the surface of the turning roller and place the bun half on the feeder cut side down. Try several buns to achieve the
correct pressure and time to achieve the desired browning and temperature of bun. With too little oil the bun surface will be an
uneven color and cool. Too much oil will give the surface a yellow untoasted look. Too much oil may also cause the bun to
stick to the grill.
NOTE: Should the temperature setting be changed, allow several cycles for the grill plate to adjust. Once the desired
setting has been achieved, note the temperature and keep it there.
CLEANING
Turn main power switch OFF. Remove power supply plug from the wall outlet.
Some surfaces will remain hot after toaster is turned off. Allow time for toaster to cool and use caution during disassembly and
cleaning.
To remove butter roller, lift left side of the butter roller shaft out of the collet and remove. To facilitate cleaning, the shaft
assembly may be separated from the cylinder. Hold cylinder securely with one hand and slide the shaft out with the other.
Remove butter pan.
To remove front panels, remove top panel by lifting straight up. Lower panel can now be lifted off.
To remove conveyor, lift conveyor by the handles on both sides and pull towards the front of the unit to disengage gears.
Gear engagement may be tight, if so, push on the chain weights to loosen. Lift the conveyor up and off the hanger brackets.
Conveyor may be hot and is heavy, use caution when lifting and removing.
Remove feeder/Bun Chute and Teflon sheet, if used.
All parts removed may be placed in a dishwasher or sink and washed with detergent and warm water. Lubricate chains with
cooking oil after cleaning.
MAKE SURE GRILL PLATE HAS COOLED, MOISTURE MAY CAUSE BURNS. Scour grill plate thoroughly using a grill
screen or plastic abrasive pad (Scotch- Brite pads are recommended) DO NOT USE STEEL WOOL. It is not necessary to
remove all residue, as long as surface is smooth and free of burned on bread that may cause buns to stick. Rinse and dry
thoroughly then coat with a light film of cooking oil.
Reassemble.

TROUBLESHOOTING
Always ask and check the following:
1. Is the unit connected to a live power source of the proper voltage?
2. Check the circuit breaker.
3. Is power switch “ON” and pilot light glowing?
4. Check the rating label. Is the unit connected to the correct power source?
If the above checks out, and you still have problems, call an APW Wyott authorized service agent.
