CHAPTER IV 
OPERATORS INSTRUCTIONS 
This chapter covers operator’s responsibilities for daily pre-operation check, adjustments, 
replenishing C02 and syrup supplies, cleaning, and sanitizing. 
DAILY PRE-OPERATION CHECK 
  1. Make sure high-pressure C02 regulator's pound per square inch indicator is not in 
shaded portion of dial. If so, C02 cylinder is almost empty and must be replaced. 
    NOTE:  This reading should be carried out at normal room temperature. 
REPLENISHING C02 SUPPLY 
  NOTE: If pound per square inch indicator of high pressure C02 regulator on C02 
cylinder is in shaded portion of the dial, C02 cylinder is almost empty and should be 
changed. 
C02 supply must be checked daily and if necessary, replenished as instructed (see 
CHAPTER II) or contact CO2 supplier. 
COOLING UNIT MAINTENANCE 
  NOTE: Air circulation through the condenser coil, required to cool the condenser 
coil/compressor, is drawn in through grills on the cooling unit, through condenser coil and 
is exhausted out grills on the sides of the unit. Restricting air circulation through the 
cooling unit will decrease its cooling capacity. 
To avoid needless and sometimes costly repairs, it is imperative to keep condenser fins 
clean. This may be accomplished by one of three methods. One method is use of a 
condenser brush (a longhaired, soft bristle brush) to gently sweep fins of condenser 
clean. Second method is to use a strong vacuum. The third method is to use C02 or an 
air hose to blow out condenser. The latter method should only be attempted after normal 
business hours to avoid dust contamination. 
CHECKING WATER BATH 
Periodically check water level in water bath. If it is low more water should be added as 
instructed for maximum product cooling. This dehydration will normally not occur in 
normal temperate climate zones. With normal humidity the opposite will occur therefore 
a condensate drain is installed. Any extra water in the water bath will exit the unit via the 
drain outlet. When unit is building it's first ice bank it is normal to have water overflow the 
into the drain hose.
