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.
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.
