Maintenance Schedule (continued)
Periodic maintenance for soft drink equipment (listed by scheduled
frequency)
Daily (365 times per year)
w Take temperature of finished drinks. Pour off the first and take the temperature of the
second drink. The proper temperature of drinks must be 40°F (4°C) or less.
w Remove nozzles and diffusers from each dispensing valve. Clean with soap and warm
water (not hot). Rinse with carbonated water and re-install.
w Flush all dispenser drains. Pour hot water down drains at closing.
w Clean general area of syrup hookup with soap and warm water. Rinse off all soap.
Every 4 months (3 times per year)
w Using Brix cup and syrup separator, check for proper carbonated water flows (standard
flow: 5 oz. in 4 seconds, fast flow: 10 oz. in 4 seconds) and syrup to water ratios at each
dispensing station. Adjust as required.
w Inspect beverage conduits for damage. Re-insulate and seal any uninsulated areas.
Inspect floor chases and seal any open chase ends.
w Inspect air compressor filter and replace if clogged. Air filter must be replaced every six
months.
w Inspect air compressor to verify cut-in at 70 psi (4.8 bar) and cut-out at 90 psi (6.3 bar).
Adjust pressure switch if necessary.
w Inspect system for air leaks. Repair as required.
w Clean the refrigeration unit air-cooled condenser using a vacuum cleaner. If equipped
with water-cooled condenser, verify the water discharge temperature is at 105°F (41°C).
Adjust water modulating valve if necessary.
w Inspect water bath to verify water level is at the top of stand pipe. If below, add water
and repair water makeup device. If excessive amount of water is flowing over stand
pipe, locate leak within bath and repair.
w Inspect ice bank within the water bath to verify proper size ice bank and clarity. Look
for uniform, 2" to 4" thick ice bank.
w Drain, clean, and refill water bath.
w Inspect agitator motor and ensure proper operation.
w Inspect the circulating motor/pump assembly. Clean strainer and oil motor.
w Inspect the carbonating motor/pump assembly. Clean strainer and oil motor.
w Inspect entire system for leaks and repair as required.
w Verify that incoming water pressure is not less than 40 psi (2.8 bar) or greater than 60
psi (4.1 bar). If equipped with a water regulator, verify proper setting of 55 psi (3.8 bar).
Adjust if necessary.
w If pressure is low, inspect water filter cartridges to ensure they are able to supply
adequate water pressure under normal system flow. Replace if unable to provide
minimum 20 psi (1.4 bar) under load.
w Inspect syrup lines for proper flavor identification labels, replace labels if necessary.
w Disconnect syrup containers, clean connector with soap and warm water, rinse with
plain water and reconnect to syrup containers.
w Inspect pressure setting at CO
2 high pressure regulators. Verify proper 90 psi pressure
setting. Adjust if necessary.
w Inspect pressure setting at syrup pressure regulators. Verify proper pressure setting.
Adjust if necessary.
w Inspect system for CO
2 leaks. Repair as required.
