(Mc DONALD’SRAPPLICATIONS)
IMPORTANT:
TO THE INSTALLER.
It is the responsibility of
the Installer to ensure that
the water supply to the
dispensing equipment is
provided with protection
against backflow by an air
gap as defined in
ANSI/ASME A112.1.2-1979;
or an approved vacuum
breaker or other such
method as proved effective
by test.
Water pipe connections
and fixtures directly
connected to a potable
water supply shall be

SAFETY INFORMATION
Recognize Safety Information
This is the safety-alert symbol. When you see this
symbol on our machine or in this manual, be alert to
the potentially of personal injury.
Follow recommended precautions and safe operating
practices.
DANGER
Understand Signal Words
A signal word - DANGER, WARNING, OR CAUTION
is used with the safety-alert symbol. DANGER identi-
fies the most serious hazards.
Safety signs with signal word DANGER or WARNING
are typically near specific hazards. WARNING
General precautions are listed on CAUTION safety
signs. CAUTION also calls attention to safety mes-
sages in this manual. CAUTION
Follow Safety Instructions
Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in
good condition. Replace missing or damaged safety signs. Learn how to operate the machine and how to
use the controls properly. Do not let anyone operate the machine without instructions. Keep your machine in
proper working condition. Unauthorized modifications to the machine may impair function and/or safety and
affect the machine life.
CO2(Carbon Dioxide) Warning
CO2Displaces Oxygen. Strict Attention must be observed in the prevention of CO2(carbon dioxide)
gas leaks in the entire CO2and soft drink system. If a CO2gas leak is suspected, particularly in a
small area, immediately ventilate the contaminated area before attempting to repair the leak. Person-
nel exposed to high concentration of CO2gas will experience tremors which are followed rapidly by
loss of consciousness and suffocation.
CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be sanitized and
all sanitizing solution must be purged from the syrup systems. All water must also be purged from
the plain and carbonated water systems. A freezing ambient temperature will cause residual water
remaining inside the Unit to freeze resulting in damage to internal components of the Unit.

GENERAL INFORMATION
This manual is a guide for installing, operating, and maintaining this equipment. Refer to Table of Contents for
page location of detailed information pertaining to questions that arise during installation, operation, service and
maintenance, or troubleshooting this equipment. This section gives the unit description, theory of operation, and
design data for the Six and Eight-Flavor Vanguard 245 Post-Mix Overcounter Dispensers (hereafter referred to
as Units).
This Unit contains no User serviceable parts and must be installed and serviced by a qualified Service Person.
UNIT DESCRIPTION
The Units are compact and may be installed on a countertop as a self-serve Unit or the Unit may be installed in
a drive-through or may be center-island mounted. The Units are equipped with 3/4 H.P. drop-in type
refrigeration assemblies that are easily removed for service and maintenance. Adjustable water flow regulators
and syrup flow regulators, located on the dispensing valves, are easily accessible to control the water flow rate
of the dispensing valves and Water-to-Syrup ‘‘Ratio’’ of the dispensed product.
The six-flavor Vanguard 245 Post-Mix Dispenser (P/N 497306660WS) is equipped with a plain water dispensing
spout located between No. 5 and No. 6 dispensing valves (see Figure 2 and 9) that when activated, will
dispense chilled plain water.
The only requirements for operation are installation of the Unit, installation of LOOSE-SHIPPED PARTS, filling
water tank with water, connection to a remote carbonator (Unit requiring connection to a remote carbonator),
connections to plain water and syrup supplies, adjustment of CO2regulators, plugging Unit power cord into an
electrical outlet, and adjusting the dispensing valves water and syrup flow regulators for proper water flow rate
and Water-to-Syrup ‘‘Ratio’’ of the dispensed product.
Available is an optional Straw Holder (P/N 560000440) that provides a place to store drink straws and a Cup Lid
Holder (P/N 560000439) that provides a place to store a supply of cup lids. A Plain Water Cooling Coil
(P/N 560000477) is available that may be installed in the Unit that provides pre-cooled plain water that may be
connected to a remote Orange Juice Dispenser. Also available is a CO2“OUT”Light Kit (P/N 1983) and a
Dispenser Leg Kit (P/N 560000126) to raise the Dispenser up off the countertop.

from remaining dispensing valves. The still (non-carbonated) drink dispensing valves may be
converted to also dispense a carbonated drinks. Refer to TABLE OF CONTENTS for converting still
(non-carbonated) drink dispensing valves to dispense carbonated drinks.
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the applicable syrup
tanks or bag-in-box syrup pumps and also the remote carbonator. Plain water enters the remote carbonator
water tank and is carbonated by CO2gas pressure also entering the water tank. When dispensing valve is
opened, CO2gas pressure exerted upon the applicable syrup tank contents or bag-in-box syrup pump pushes
syrup from the syrup supply, through the Unit cooling coils, and on to the dispensing valve. Carbonated water is
pushed from the remote carbonator by CO2gas head pressure and is pushed through the Unit cooling coils to
the dispensing valve. Syrup and carbonated water meet simultaneously at the dispensing valve resulting in a
carbonated drink being dispensed. A still (non-carbonated) drink is dispensed from the No. 3 dispensing valve
(six-flavor Unit) or No. 4 dispensing valve (eight-flavor) Unit in the same manner as the carbonated drink except
plain water is substituted for carbonated water.
The six-flavor Vanguard 245 Post-Mix Dispenser (P/N 497306660WS) is equipped with a plain water dispensing
spout located between No. 5 and No. 6 dispensing valves (see Figure 2 and9). A filtered plain water supply line
is connected to the plain water solenoid valve on top of the refrigeration deck. Pressing the plain water dispense
switch on side of the drip tray support opens the electrically operated plain water solenoid valve which permits
chilled plain water to be dispensed.
UNIT WITH INTEGRAL (BUILT–IN) CARBONATOR
(see applicable Figure 5 or 6 )
NOTE: The Unit was set up at the factory to dispense still (noncarbonated drinks) from No. 4 and No. 5
dispensing valves and carbonated drinks from the remaining dispensing valves. If the factory installed
option to convert No.4 or 5 or both No.4 and 5 to dispense a carbonated drink instead of a still
(non-carbonated) drink was installed on your Unit, refer to TABLE OF CONTENTS for the conversion
instructions.
A CO2 cylinder delivers carbon dioxide (CO2) gas through adjustable CO2 regulators to the applicable syrup
tanks or bag-in-box syrup pumps and also the integral (built-in) carbonator. Plain water enters the integral
carbonator carbonated water tank and is carbonated by CO2 gas pressure also entering the water tank. When
dispensing valve is opened, CO2 gas pressure exerted upon the applicable syrup tank contents or bag-in-box
syrup pump pushes syrup from the syrup supply, through the Unit syrup cooling coil, and on to the dispensing
valve. Carbonated water is pushed from the integral carbonator carbonated water tank by CO2 gas head
pressure and is pushed through the carbonated water manifold to the dispensing valve. Syrup and carbonated
water meet simultaneously at the dispensing valve resulting in a carbonated drink being dispensed. A still
(non-carbonated) drink is dispensed from No. 4 and No. 5 dispensing valves in the same manner as the
carbonated drink except plain water is substituted for carbonated water.
