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 with 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.
