SAFETY PRECAUTIONS
Always: Disconnect power to the dispenser before servicing or cleaning.
Never: Place hands inside of hopper or gate area without disconnecting power to the dispenser. Agitator rotation
occurs automatically when dispenser is energized!
This ice dispenser has been specifically designed to provide protection against personal injury and eliminates
contamination of ice.To insure continued protection and sanitation, observe the following:
ALWAYS: Be sure the removable lid is properly installed to prevent unauthorized access to the hopper interior
and possible contamination of the ice.
ALWAYS: Be sure the upper and lower front panels are securely fastened.
ALWAYS: Keep area around the dispenser clean of ice cubes.
CAUTION: Dispenser cannot be used with crushed or flaked ice.
Use of bagged ice which has frozen into large chunks can void warranty. The
dispenser agitator is not designed to be an ice crusher. Use of large chunks of
ice which ”jam up” inside the hopper will cause failure of the agitator motor and
damage to the hopper. If bagged ice is used, it must be carefully and completely
broken into small, cube-sized pieces before filling into the dispenser hopper.
DESCRIPTION
The “DURAFLEX”series of ice dispensers solves your ice and beverage service needs in a sanitary, space sav-
ing, economical way. Designed to be manually filled with ice from any remote ice making source, these dispensers
will dispense cubes (up to 1-1/4 in. in size), cubelets, and hard-chipped or cracked ice; and in addition, several
flavors of post–mix beverages. The unit includes beverage faucets and a cold plate and is designed to be sup-
plied direct from syrup tanks and a carbonator, with no additional cooling required.

INSTALLATION INSTRUCTIONS
1. Locate the dispenser indoors on a level counter top.
The ice dispenser must be sealed to the counter. The MOUNTING TEMPLATE (see Figure 3)
indicates where openings can be cut in the counter. Locate the desired position for the dispenser, then
mark the outline dimensions on the counter using the MOUNTING TEMPLATE. Cut openings in the
counter.
Rotate the line support bracket, located under base, to the up position and route all the lines below the
bracket.
Apply a continuous bead of National Sanitation Foundation (NSF) listed silastic sealant (Dow 732 or
equal) approximately 1/4”inside of the unit outline dimensions and around all openings. Then, position
the unit on the counter within the outline dimensions. All excess sealant must be wiped away
immediately.
2. The beverage tubes, drain tube and power cord are routed through the large opening in the bottom of the
unit. See the MOUNTING TEMPLATE (see Figure 3), for locating the required clearance hole in the counter
for these utility lines.
3. DRIP TRAY DRAIN ASSEMBLY (see Figure 2). Route the drain tube to an open drain with the end of the
tube above the “flood”level of the drain. Use the tubing, fittings, clamps, and insulation provided with the Dis-
penser to assemble the drain. The completed drain line must pitch continuously downward and contain no
“traps”or improper drainage will result.
NOTE: This equipment must be installed with adequate backflow protection to comply with federal, state,
and local codes.
4. Connect the beverage system product tubes as indicated in the Flow Diagram. This work should be done by
a qualified Service Person. Any non-carbonated water tubing must be connected to the outlet of the check
valve.
Note: See the Flow Diagram (see Figure 4) or decal on lower front panel of the unit for the location of syr-
up and water connections.
Note: Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed and maintained according to Federal, State and Local Laws.
5. ICE PORTION CONTROLLER: Regulated CO2gas pressure is required to operate the portion control dis-
pensing system. Proceed as follows to connect the CO2gas pressure source line to the dispenser.
A. Connect and route the CO2line from outlet side of the source regulator assembly up to the dispenser.
NOTE: That the minimum source-regulated pressure is 40 psig.
B. Connect the CO2source line to dispenser inlet line labeled “CO2“.
C. The dispenser regulator outlet pressure is factory preset to 34 psig ±2 psig DO NOT ADJUST.
IMPORTANT: Maximim CO2operating pressure is 50 psig.
6. Clean the hopper interior (see Owner’s Manual P/N 620916502 for cleaning instructions).
7. Connect the power cord to a 120 volt, 60 cycle, 3–wire grounded receptacle.
