1.0 GENERAL INFORMATION
1.1 Introduction
The Burford Model 8830 Applicator utilizes (3) individual spray rail assemblies to
spray a controlled amount of garlic oil, soy oil or butter onto product, without
interruption to the pan flow.
The following pages contain installation, operation and maintenance instructions. To
ensure maximum performance, these instructions should be followed with care.
1.2 Specifications
1. Air – 1 scfm @ 60 psi
2. Electricity – 208/220-50/60-1 phase @ 30 amps

2-1
2.0 THEORY OF OPERATION
2.1 Operation Sequence
Start the conveyor, place a pan on it, and allow it to travel toward the
spray rail assembly. It will encounter the pan sensor. This sensor will
sense the leading edge of the pan and send a signal to the plc to activate
the applicator nozzles to apply the selected liquid as each pan passes.
2.2 Machine Description
Product Pump
Control Panel
Melting Racks
Ethernet Connections

3.0 INSTALLATION PROCEDURES
3.1 Determining the best location to mount on existing conveyor
1. The portion of the conveyor that is to be used should have at least 30 inches of
free length.
2. The conveyor sides should be free of any interference from bolts, conduit, motors,
shafts, junction boxes, guarding, support members, etc.
3. The underside of the conveyor should also be clear of the interference listed in
number two.
4. The top of the conveyor should be of an open style, (opening between conveyor
chain) so the actuation switch is free to move from side to side, upstream, and
downstream.
5. Pan guides must be used to keep pans straight when traveling through the unit.
6. The conveyor chosen should not allow the pans to stop, turn or back-up during
operation.
7. Area around the unit installation should be clear of any obstruction and unit shall
not be installed in such a way as to create a safety hazard, or block a normal
passageway. Clearance must conform to all local safety codes.
8. Installation site should have ample clearance on operator side for easy access and
normal maintenance. Consideration must be made for positioning the tank
assembly within 10 feet of installation site.
3.2 Utility Installation
A qualified electrician must make all electrical connections. A suitable circuit must be
chosen so the 30 AMP requirement does not overload the total current capacity. A
suitable circuit with all safety requirements must comply with local electrical codes.
Once the unit is mounted to the conveyor and the uprights containing the nozzles are in
place, the tank assembly can be located next to the conveyor. This should be mounted so
the machine operator can have easy access to the controls.

4.0 USING THE OPERATOR CONTROLS
4.1 Control Panel Description
Other than mechanical set-up and manual nozzle spray, the operator control
panel controls all functions required to operate the applicator. The functions of
the operator control panel are outlined below.
ITEM DESCRIPTION FUNCTION
1 Light Tower Notifies operator of machine status. See Section 11.1
for descriptions.
2 Primary Disconnect Remove electrical power from unit.
3 Main Display
Displays menu screens, error messages and allows
convenient operator interface. Simply touch the screen
at the desired function and follow pop-up screen
instructions.
4 Start/Stop Button Removes electrical power from machine components.

4.2 Main Screen Functions
Touch desired box or icon to access the desired machine function. Once the
desired function is highlighted by the enlarged lettering a 10 second wait
period is required for the function to initiate.
DESCRIPTION FUNCTION
OFF Turns “OFF” all internal relays and CLEARS the programming registers residing in the
Programmable Logic Controller (PLC).
PREHEAT
Turns “ON” the melting rack and product tank water jacket circulating pumps and
initializes the temperature controls. The agitator is also turned “ON” after a 15 second
delay timer expires; provided the tank lid (section 6.4) is in place. The product pump
and spray nozzle trigger sensor are NOT energized.
CIRCULATE
Melting rack, product tank water jacket, agitator and butter pump are turned “ON”.
Spray nozzle trigger sensor is NOT energized. Product pump will be at low speed for
10 seconds then switch to normal run speed once proper operating pressure is
verified.
RUN Same as “CIRCULATE”, except trigger sensor will activate spray.
LOGIN / LOGOUT LOGIN allows authorized users to enter their user name and password and access the
“MANUAL EDIT MODE”. LOGOUT returns the unit to “AUTO MODE”.
MANUAL EDIT
MODE
This mode is password protected and allows the authorized user to create recipes and
make additional machine setting changes. NOTE: This box is not shown until an
authorized user has completed the “LOGIN” sequence.
Other Functions Touch desired “ICON” to access additional pop-up screens. Follow pop-up screen
instructions. Individual “ICON” settings are accessible while in “MANUAL EDIT
MODE”, which is password protected, see your supervisor.
NOTE: See Section 5 for additional screen information.

4.0 USING THE OPERATOR CONTROLS, cont’d.
4.3 Melting Rack Temperature Control
Butter must be pre-melted to enter the product tank. A heater is located in the
return side of the each melting rack and heats water as it circulates through the
melting rack. As the butter melts, it falls into the product tank, where the product
is stabilized at the appropriate temperature. The recommended temperature
setting for the temperature controller is 120°Fahrenheit (range: 65°-135°F.). A
lower setting could require excessive time for the butter to enter the product tank.
Once the desired amount of butter is melted into the product tank, melting rack
control should be turned “OFF” to avoid scorching residual butter left on the
melting rack bars and screen.
1. Touch the desired melt rack
“ICON” to access the “SET
TEMP” pop-up screen. Note that
the melting racks are controlled
individually.
2. Touch the “SET TEMP” box to
modify the temperature setting.
This box is ONLY accessible
when in the “MANUAL MODE”.
CAUTION: Melting rack heats quickly but cools down very
slowly. Use care NOT to set temperature too high.
