Refrigerant Requirement see Unit Nameplate

Electrical Requirements see Unit Nameplate

THEORY OF OPERATION

(see applicable Figure 2 or 3)

NOTE: The flow diagram (see applicable Figure 2 or 3) indicates plain water is to be connected to No. 4
dispensing valve enabling No. 4 valve to dispense a still (non-carbonated) drink and the remaining
dispensing valves dispensing carbonated drinks. If desired, carbonated water may also be connected
to the No. 4 dispensing valve enabling No. 4 valve to also dispense a carbonated drink.

A CO2 supply delivers carbon dioxide (CO2) gas through adjustable CO2 regulators to the syrup system and
also to the remote carbonator. Plain water enters remote carbonator carbonated water tank tank and is
carbonated by regulated CO2 gas pressure also entering the tank. When dispensing valves are opened, CO
pressure exerted upon the syrup supplies pushes syrup from the syrup supplies, through the Unit syrup cooling
coils, and on to the dispensing valves. Carbonated water is pushed from the remote carbonator carbonated
water tank by CO

gas head pressure and is pushed through the Unit carbonated water cooling coils to the

2

dispensing valves. Syrup and carbonated water meet and mix at the dispensing valves resulting in carbonated
drinks being dispensed. A still (non-carbonated) drink is dispensed from No. 4 dispensing valve in the same
manner as the carbonated drink except plain water is substituted for carbonated water resulting in a still
(non-carbonated) drink being dispensed.

2

The drop-in refrigeration assembly consists of a 1/3 horse power compressor, a condenser fan motor, and an
agitator motor. The compressor and condenser fan motor on and off operation are controlled by an ice bank
control.

SELECTING OPERATING LOCATION

WARNING: To avoid possible fatal electrical shock or serious injury to the operator, it is
highly recommended that a GFCI (ground fault circuit interrupt) be installed in the
electrical circuit for the domestic Units. It is required that an ELCB (earth leakage circuit

breaker) be installed in the electrical circuit for the export Units

1. Position the Unit near a properly grounded electrical outlet with proper electrical requirements. The circuit
should be fused at 15-amps (slo-blow type fuse) or the circuit must be connected through an equivalent
HACR circuit breaker. The electrical outlet must be accessible for ease of connecting and disconnecting
the Unit power cord. No other electrical appliance should be connected to this circuit. ALL ELECTRICAL
WIRING MUST CONFORM TO NATIONAL AND LOCAL ELECTRICAL CODES.

2. Close to a plain water inlet supply line to be connected to the remote carbonator and also to be routed to
and be connected to the dispenser plain water inlet line that provides plain water to No. 3 dispensing valve.

3. Close to a permanent drain to route and connect Unit drip tray drain hose.

CAUTION: Do not place or store anything on top of the Unit.

4. Clearance above top of the Unit must be open to the ceiling. A minimum clearance of 6-inches must be
maintained on back side of the Unit and a minimum of 6-inches clearance to the nearest obstruction must
be maintained on both sides of the Unit. The front of the Unit must be open to the room. These clearances
must be provided to allow for proper air flow through the Unit to cool the refrigeration system.

INSTALLING UNIT

CAUTION: This Unit is intended for indoor installation only. Do not install this Unit in an
outdoor environment which would expose it to the outside elements.

INSTALLING UNIT ON COUNTERTOP

(see Figure 4)
The Unit inlet supply lines, power cord, drip tray drain hose, and the water tank drain hose may either be routed

out the back of Unit base or through the hole cut in countertop under the Unit. Proceed to the applicable
installation procedure.

1. Out back of Unit base – Place Unit in operating location on the countertop. Route Unit inlet supply lines,
power cord, drip tray drain hose, and the water tank drain hose out through opening on back side of the
Unit base. Seal area around lines coming out of the Unit base with permagum or equivalent sealant
material.

Out hole cut in countertop under Unit – Place Unit in operating location on the countertop with its drip tray
edge flush with the countertop front edge. Mark Unit center line on edge of the countertop, then move the
Unit off to one side. Starting at the marked Unit center line on edge of the countertop, measure back
8-inches and mark center of the hole to be cut in the countertop. Cut 3-1/2 inch diameter hole in the
countertop. Place the Unit in position over the hole. Route Unit inlet supply lines, power cord, drip tray drain
hose, and the water tank drain hose down through hole cut in the countertop.

Close opening on back side of the Unit by Installing LINE OUTLET PLUG (item 3) in the opening.

NOTE: An alternate arrangement to avoid sealing the Unit base to the countertop as described, would
be to install the optional 4-inch Legs (P/N 314744000). When ordering legs, order a quantity of four.

2. To comply with National Sanitation Foundation (NSF) requirements, Unit base must be sealed to
countertop and all access holes to inside of Unit base must be sealed with permagum or other sealant
material. Proceed as follows to seal Unit base to countertop.

A. Tilt the Unit up to expose bottom of it’s base.
B. Liberally apply a silastic sealant such as Dow Corning RTV 731 or equivalent on the Unit base bottom

edges.

NOTE: Do not move the Unit after positioning or seal from the Unit base to countertop will be broken.

C. Lower Unit into operating position on the countertop to complete seal from Unit base to the

countertop.

D. Apply additional sealant around bottom of the Unit base. The seal must have a minimum radius of

1/2-inch to prevent crevices and to insure a complete seal.

E. Seal all access holes to inside of the Unit base with permagum or other sealant material.

FILL WATER TANK AND START REFRIGERATION SYSTEM

(see Figure 4)

1. Make sure plug in end of the water tank drain hose is in place.

NOTE: Use low–mineral–content water where a local water problem exists.

2. Remove water fill hole plug from top of the drop-in refrigeration assembly platform. Fill the water tank with
clean water to top of the stainless steel coils. USE LOW-MINERAL-CONTENT WATER WHERE A LOCAL
WATER PROBLEM EXISTS.

3. Install plug in the water fill hole.

4. Place power switch, located on right side of the Unit, in the ‘‘OFF’’ position.

WARNING: The Unit must be electrically grounded to avoid possible fatal electrical shock
or serious injury to the operator. The Unit power cord is equipped with a three-prong plug.
If a three-hole (grounded) electrical outlet is not available, use an approved method

to ground the Unit.

5. Plug the Unit power cord into a properly grounded electrical outlet.

6. Place the Unit power switch (located on right side of the Unit) in the ‘‘ON’’ position. The refrigeration
compressor, condenser fan motor, and agitator motor will start and begin forming an ice bank. When full ice
bank has been formed, the compressor and the condenser fan motor will stop but the agitator motor will
continue to operate circulating ice water bath in the water tank.

7. Install hood on the Unit and secure with screw.

CONNECTING DRIP TRAY DRAIN HOSE TO A PERMANENT DRAIN

(see Figure 4)

NOTE: The drip tray drain hose routed to a waste container is not recommended due to sanitation and
