INSPECTION –  
Upon receipt of the cabinet, carefully  
examine the crating for damage.  
If  
damage is found, make a note on the  
delivery ticket before signing. Carefully  
remove shipping crate and examine the  
cabinet for “concealed” damage.  
If  
damage is found contact the delivering  
carrier immediately and have his agent  
prepare an inspection report for the  
purpose of filing a claim. This is your  
responsibility.  
SPECIFICATIONS  
CONSTRUCTION –  
The base is an all welded assembly of  
heavy dusty steel to provide a strong  
frame on which the rest of the cabinet is

operation, must not vary more than 5%  
from cabinet serial plate rating. If a low  
voltage condition exists, contact your  
electrician or power company.  
The location of your cabinet is important.  
Make sure your selected location is NOT  
in any of the following areas as it could  
seriously affect the operation.  
A wiring diagram is provided on the  
condenser shroud for each unit.  
Not in direct sunlight.  
A power (ON-OFF) switch is provided on  
each model. The switch is accessible  
through a hole provided in the rear  
(operator side) access panel  
Not in the air path of heat or air  
conditioning ducts.  
Not at an exit or entrance affected by  
extreme temperature change.  
START UP PROCEDURE -  
Allow 2 feet of clearance at the rear of the  
case to allow adequate air movement  
across the condenser for proper  
refrigeration system performance, do not  
obstruct the grille at the rear intake and  
discharge. If desired, the blank off panel  
behind the front (customer side) louvered  
panel – may be removed for rear air  
intake and front air discharge, but then  
insure 2 feet of unobstructed clearance is  
left at the case front.  
Cut the band which holds the  
compressor in place during shipment.  
Make sure fan turns freely. Check for  
any connections or parts that might  
have loosened during shipment.  
Start cabinet, and allow temperature  
to pull down to normal level before  
loading product.

TEMPERATURE CONTROL –  
Remove heater from under base  
frame.  
The thermostat, which senses the cold  
wall temperature, is located at the lower  
rear right corner of the cabinet through  
the access panel. It has been pre-set at  
the factory to maintain product  
temperatures between +10° and +4°. The  
thermostat is adjustable. If other than  
normal temperatures are required, adjust  
the control by turning the knob clockwise  
for colder and counter-clockwise for  
warmer temperatures.

interior walls with a plastic scraper will  
extend the length of time between  
complete defrosting.  
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  
by:  
Defrosting may be accomplished with the  
aid of a hair dryer, plastic scraper or by  
merely letting the cabinet remain open  
until the walls are cleared. Care should

be taken not to puncture the interior  
walls or remove paint from the walls  
during this procedure.  
CLEANING EXTERIOR / INTERIOR –  
When cleaning the exterior of the cabinet  
use a soft cloth or sponge with water and  
mild detergent. Rinse and wipe dry.  
Be sure to disconnect power from the  
cabinet prior to starting defrost  
operation. After the cabinet is completely  
defrosted, wash thoroughly, remove  
defrost water (Hussmann dipping cases  
are provided with an outside drain  
located on the operator’s side of the case  
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.  
Disconnect the electrical  
power and allow cabinet to warm to  
above freezing temperature. Use a soft  
cloth or sponge with a mild detergent to  
wash the interior.  
Wipe dry before  
Be sure to allow the cabinet to cool down  
to its operating temperature before

TEMPERATURE CONTROL  
REPLACEMENT –  
CLEANING THE CONDENSER –  
The Ranco temperature control is located  
in the compressor compartment.  
To  
replace, first disconnect power supply and  
remove two screws holding control dial  
plate. Pull capillary tube from control  
well, noting length of tube removed. Push  
new cap tube into well, being careful not  
to kink it, and making certain it reaches  
full depth of well.  
To clean condenser, a soft, nylon brush  
should be used to loosen dirt and lint.  
Then vacuum up the dirt or blow  
condenser out with a high-pressure gas  
such as nitrogen. Never use a wire brush  
to clean condenser tubes.

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.  
10  
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.  
11  
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.
