Maintenance Schedule
This section provides a list of periodic maintenance tasks
and the scheduled frequency required to ensure the proper
operation of your Multiplex dispensing equipment. To
ensure quality beverages, prevent downtime, and reduce
costs, these tasks must be performed as indicated.
PERIODIC MAINTENANCE FOR EQUIPMENT (LISTED BY
MAJOR COMPONENTS)
Dispensing stations
Daily (365 times per year)
• 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.
• Remove nozzles and diffusers and soak in mild
detergent cleaning solution. Scrub parts with small
bristle brush taking care to clean small crevices and
O-ring grooves. Turn OFF power to dispensing valves.
Scrub exterior surfaces, including bottom splash area
and actuator lever, with cleaning solution. Reassemble
diffusers and nozzles. Wipe dry exterior surfaces before
turning ON power.
• Flush all dispenser drains. Pour warm water down drains
at closing.
Beverage conduits
Every 3 months (4 times per year)
• Inspect beverage conduits for damage. Re-insulate and
seal any un-insulated areas.
• Inspect floor chases and seal any open chase ends.
Air compressor
Monthly (12 times per year)
• Drain condensate water from air compressor tank.
Every 4 months (3 times per year)
• Inspect air compressor filter and replace if clogged. Air
filter must be replaced every 6 months.
• 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.
• Inspect system for air leaks and repair as required.
Refrigeration unit
Every 4 months (3 times per year)
• Clean the refrigeration unit air-cooled condenser using
a vacuum cleaner or soft bristle brush. If equipped with
water-cooled condenser, verify the water discharge
temperature is at 105°F (41°C). Adjust water modulating
valve if necessary.
• 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.
• Inspect ice bank within the water bath to verify proper
size ice bank and clarity. Look for uniform, 2” to 4” thick
ice bank.
• Drain, clean, and refill water bath.
• Inspect agitator motor and ensure proper operation.
• Inspect the circulating motor/pump assembly, oil motor.
• Inspect the carbonating motor/pump assembly. Clean
strainer and oil motor.
• Inspect entire system for leaks and repair as required.
Water filters
Every 4 months (3 times per year)
• 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.
• 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.
Syrup supply
Daily (365 times per year)
• Clean general area of syrup hookup with soap and
warm water. Rinse off all soap.
Every 4 months (3 times per year)
• Inspect syrup lines for proper flavor identification labels.
Replace labels if necessary.
• Disconnect syrup containers. Clean connector with soap
and warm water. Rinse with plain water and reconnect
to syrup containers.
