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 the 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 unautho-
rized access to the hopper interior and possible contamination of 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.

GENERAL DESCRIPTION
The Remcor “DB”series of ice dispensers will solve ice and beverage service needs in the sanitary, space sav-
ing, economical way. Designed to be manually filled with ice from any remote ice making source, these dispens-
ers will dispense cubes (up 1-1/4”in size), cubelets, hard-chipped or cracked ice and Scotsman MH750 pellet
ice; and in addition, several flavors of post-mix beverages. “B”models contain beverage faucets only and must
be supplied with cold product from any remote cold plate or refrigerated soda factory. “-BC”models include bev-
erage faucets and a cold plate and are designed to be supplied directly from the syrup tanks and carbonator,
with no additional cooling required.
IMPORTANT: For dispensing Scotsman “pellet” style ice (Model MH750 icemakers), REMCOR Kit
#02234 Ice Diverter must be installed on the dispenser. (See INSTALLATION INSTRUCTIONS)

INSTALLATION INSTRUCTIONS
1. Locate the dispenser indoors on a level counter top.
COUNTER MOUNTING
The ice dispenser must be sealed to the counter. The template drawing indicates openings which must be
cut in the counter. Locate the desired position for the dispenser, then mark the outline dimensions on the
counter using the template drawings. Cut openings in the counter.
Apply a continuous bead of NSF International (NSF) listed silastic sealant (Dow 732 or equal) approximate-
ly 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 line and power cord are routed through the large opening in the bottom of the
unit. See the MOUNTING TEMPLATE, for locating the required clearance hole in the counter for these util-
ity lines.
3. SINK DRAIN ASSEMBLY: Connect the drain tube to an open drain. Additional drain tubing is provided with
the unit. The drain line must continuously pitch downward away from the unit and contain no “traps”or im-
proper drainage will result.
A. Use tube, clamp and insulation provided to assemble drain.
B. To assure proper drainage, do not allow “trap”to form in drain line. Be sure drain line runs flat with
bottom of dispenser.
4. Connect the beverage system product lines as indicated in Figure 2 (and in Figure 3 for cold plate units).
This work should be done by a qualified service person. Note that the hoses are marked with numbers ( 1
through 4 or 5) for syrup connections On 5 valve “-BC”units, the plain water is marked “NON CARB
WATER”.
5. Clean the hopper interior (see CLEANING INSTRUCTIONS).
6. Connect the power cord to a 120 volt, 60 cycle, 3-wire grounded receptacle.
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/

FIGURE 2. GATE RESTRICTOR PLATE
ADJUSTMENT
This dispenser is provided with a gate restrictor plate, installed in its highest position. This plate adjusts the rate
of ice flow from the dispenser. In applications using buckets, carafes or other large containers, the plate may be
removed entirely for maximum ice flow. For glasses and cups, the plate may be adjusted downward to reduce
the flow of ice. The best position depends on the type of ice being used and the size container and must be
found by trial and error. Adjustment is made by loosening the upper two ice chute retaining nuts, sliding the re-
strictor plate to the desired position and re-tightening the nuts.
If the dispenser fails to dispense the ice when operated, check that the hopper has ice in it and that power is
being supplied to the unit. If the problem persists, refer to the troubleshooting guide (page 16).

MAINTENANCE
The following dispenser maintenance should be performed at the intervals indicated:
DAILY or as required
Remove foreign material from the vending area sink to prevent drain blockage.
WEEKLY or as required
Clean vending area. Check for proper water drainage from the vending area sink.
MONTHLY
Clean and sanitize the hopper interior (see CLEANING INSTRUCTIONS).
START-UP AND OPERATING INSTRUCTIONS
Fill the hopper with ice. For “--BC”models with a built-in cold plate, dispense several large cups of ice (approxi-
mately 20 to 30 seconds total dispensing time) to allow ice to fill the cold plate. Add ice to the hopper as neces-
sary to refill and replace the lid. Allow 10 to 15 minutes for the cold plate to cool down. Repeat this procedure
whenever the dispenser has been standing overnight or other long periods without ice use. On “--B”and “--BC”
models, start up the beverage system and adjust faucets to the proper brix. Contact your local syrup distributor
for complete information on the beverage system.
In normal operation, pushing the ice dispenser lever will cause ice to flow from the ice chute. Ice flow will contin-
ue until the lever is released. Pushing the lever on any faucet will provide beverage of the appropriate flavor.
CAUTION: Use caution to avoid spilling ice when filling dispenser. Immediately clean up
any spilled ice from filling or operating the unit. To prevent contamination of ice, the lid
must be installed on the unit at all times.
