The DCSG/DCCG-4 8, 12, and 16 are

specifically designed for dipping/display

of bulk ice cream, sherbet, or frozen

yogurt. Wide glass front and one-piece

molded lids provide an unobstructed view

of the product for impulse merchandising.

Optional items include easy to use can

holder trays and dipper wells. The –D

models on -8, -12 and -16 include the

labor saving storage doors feature.

The liner is an all welded assembly of

electro zinc steel. Copper evaporator

tubing is fastened to the liner and

applying a conductive material on both

top and bottom of the tubing further

enhances maximum heat transfer. The

liner is also chemically treated and

Most installations will require a complete

defrosting every seven to ten days.

Usually the best time to defrost is at the

close of business so the cabinet will be

regulated for the start of the next business

day.

ANTI-SWEAT HEATERS –

A resistance heater is installed in the

perimeter of the base frame of the canopy

to prevent condensation. Continuity of

the heater circuit maybe checked at the

splice located inside the ballast enclosure

in the compressor compartment.

The ice cream should be removed from

the cabinet and placed in a walk-in or

storage freezer during the defrosting

operation. A power switch for turning

the case off for defrosting is located

through the access panel.

Should the heater fail it may be replaced

CLEANING EXTERIOR / INTERIOR –

When cleaning the exterior of the cabinet

use a soft cloth or sponge with water and

Be sure to disconnect power from the

cabinet prior to starting defrost

base to assist you in this operation), wipe

the interior dry, and turn the power back

on.

For cleaning the interior of the product

compartment, a built-in drain has been

provided with a standard hose fitting

located at the front of the cabinet in the

base area.

Operational Data

The following operational data is based on lab tests, and may vary under field

conditions. The conditions shown at the non-recommended high 85°F ambient are shown

for information only and a possible reason for jobsite problems. Note that during August,

2002, the DCC/SG-8 cases changed from semi-hermetic (SH) to hermetic (H) and similarly,

during December, 2003, the DCC/SG-12 cases changed from the semi-hermetic (SH) to

hermetic (H) style compressors which operate under different pressures.

DIPPING USERS GUIDE

The general success of any ice cream dipping department depends to a great extent on the

people within that department. If at all possible, a single individual should be assigned the

direct responsibility of assuring that proper operational procedures are being followed.

LOADING –

‡

Careful thought should be given to the placement of flavors within the cabinet prior to

the opening of the dipping department. Flavors with the highest sugar content (ripple,

maple syrup, and candy) require a lower temperature for dipping than vanilla. Since

temperatures will vary slightly within the cabinet, it is recommended that these flavors

be placed in the corners where maximum cooling effect from two walls can be taken

advantage of.

STORAGE –

‡

In order to assure product quality and minimum energy usage, it is important that

proper attention is given to the maintenance of product temperatures prior to placement

in the display freezer. Storage temperatures are generally maintained at –12 degrees F

to –18 degrees F. This allows for long-term storage of ice cream without deterioration.

Dipping temperatures are generally maintained at +5 degrees F to +9 degrees F, which

allows for rather limited display time before deterioration begins to occur.

‡

Ice cream removed from a delivery truck, walk-in freezer, or storage cabinet should be

placed in the dipping cabinet immediately.

The dipping cabinet is not designed as a hardening cabinet, and will generally only

maintain ice cream at the preset dipping temperature.

If ice cream is allowed to warm up prior to placement in the dipping cabinet,

crystallization may occur resulting in some loss of product quality.

LIDS –

‡

To conserve energy and minimize frost accumulation on the cabinet interior walls, the

lids should remain closed until the customer has made his/her choice of flavors, and

should be closed immediately once the customer has been served. Under no

circumstances should the cabinet lids be left open for extended periods of time.

TEMPERATURE CONTROL –

‡

The temperature control is factory set for normal dipping temperatures. If, after a week

or so of operation, it is decided that a higher or lower temperature is required, only a

qualified refrigeration mechanic should adjust the control. Other than the initial

adjustment and possibly a seasonal adjustment, no other setting should be required. If

the cabinet temperature fluctuates to any great extent, a refrigeration mechanic should

be notified. Employees should not be allowed to tamper within the control setting.

LOAD LIMITS –

A fully loaded cabinet will use less energy and maintain generally more even

temperatures than one that is only partially full. However, care should be taken not to

exceed the load line limits as noted on the interior cabinet walls through the use of wire

racks, stepshelving, or by stacking containers three high.

DIPPING –

‡

Much of the success of hand dipping and appeal of the stored ice cream to the customer

depends on the training of personnel in proper dipping methods. Periodic scraping of

the container sidewalls and leveling off of the ice cream is essential to avoid discoloration

and drying out of the ice cream. Scraping the container sidewalls and leveling off the ice

cream should be done lightly with the use of a spade. Start with the back of the spade

turned towards the side of the can, working from the top of the can down. Once the

walls are cleared, the top portion of the remaining ice cream should be leveled off, filling

in holes left by previous dipping.

MAINTENANCE –

Proper maintenance of refrigeration equipment can have a dramatic effect on the

equipment’s ability to perform, as well as power consumption and customer reaction to

your dipping operation.

‡

Hussmann equipment is designed so that a minimum amount of maintenance is

necessary. The relatively few items that do require attention should be scheduled for

specific time periods based on prevailing store conditions and cabinet usage.

WARRANTY –

Please read carefully to assure prompt and accurate service

Ordering Replacement Parts –

Contact your nearest Hussmann

Always specify model and serial number of

If correct part number is not known, give a clear description of part itself

and its function in the cabinet.

Warranty Parts Procedure –

Same as items above

Give original installation date of cabinet and, if possible, forward a copy of the

original invoice or delivery receipt.

All shipments of in-warranty replacement parts will be invoiced from the factory until

such time as the defective part is returned and proved to be defective by our Quality

Control Department.

Contact your Hussmann Distributor for instructions on returning in-warranty parts.

Warranty parts must be returned to the factory within 30 days of date of failure to

assure proper disposition.

Lack of any of the above information may result in the shipment of the wrong part, or a

delay in shipment.

Compressor Replacement Procedure –

Replacement compressors will not be shipped from the Hussmann factory. They

may be obtained from your nearest Copeland Wholesaler.

Your wholesaler will replace, free of charge, any compressor found to be defective within

twelve months of installation, not to exceed twenty months from the date of

manufacture, as determined by the compressor serial number on the compressor serial

plate. For any defective compressor beyond the twelve or twenty month time period, a salvage

value credit will be given too partially offset the invoice for the replacement.
