The dehydrators require maintenance of about 2 years of operation. The desiccant material
and active carbon will have to be changed.
The scrubber does not have any parts that requires changing but is good practice to check the
water flow after 1 year of operation to make sure that the nozzle is not clogged, and
everything is running as intended.
The Compressor has a few different areas that need maintenance. Every 3
rd
month the main
bearing is greased. Daily perform routine check on noise and the pressure gauges, or at least
weekly. 8-12 months for changing compressor seals.
The Gearmotor has its own lubricant oil in a closed system, this oil should be changed after 2
years of service or according to the gearmotors manual.
The Sulfur filter has an operation time of 2 years before it is needed to replace the active
carbon.
Pressure relief valve for the CO2 collection circuit, which is located before the gas reaches the
Unit should be cleaned every 3
rd
month to avoid sticking problems from glucose.
The particle filter should be changed once or twice a year depending on the Unit’s operation
hours. If the filter is dirty, contact Dalum Beverage Equipment.
Solenoid valves, check drain valves for leakage by observing the drain hose with closed
valves. Check other valves for leakage (closed leaking valves are very cold).
