4. MAINTENANCE
Although the MC system requires very little maintenance itself,
some components such as the air
compressor may require more. You should always follow the
component manufacturer’s recommended maintenance
schedules. The following maintenance is recommended:
• Air compressor. Follow the manufacturer’s recommendations.
An overloaded or improperly maintained compressor will
throw more oil off into the air supply and may increase the
maintenance of the atomizing heads.
• Atomizing heads. Once per year, the air cap at the front of each
nozzle should be removed for inspection. The water nozzle
located inside the air cap should be cleaned off with a soft cloth
saturated with a 5% phosphoric or acetic acid solution. The air
caps should be immersed in the same solution until clean. The
air cap orifice should be checked for wear or occlusion. Place
the air caps back on the heads tightly.
The piston should be removed, cleaned and regreased every 3-5
years. The O-rings are replaced every 8-10 years. Follow these
steps when performing total cleaning and regreasing of the
nozzles:
• Before disassembling the nozzles, mark the back adjustment
screw or count the number of turns while removing it. This will
insure proper calibration when reassembling the nozzles.
• After disassembling, clean nozzle parts using any standard
humidifier cleaner or 5% phosphoric acid.
• Replace O-rings if they appear cracked or worn.
• Lubricate all parts indicated ONLY with CAREL approved
lubricant (Dow Corning #4 Insulating Compound).
• Reassemble nozzle. CAREL also offers a nozzle cleaning service
at nominal charge. Contact your local CAREL representative for
details.

• Air and water lines. Once per year, the air and water lines should
be blown out to get rid of any debris, sediment or oil that may
have collected.
• Regulators, solenoids, valves. Once per year, open these
devices, inspect them for wear, and clean them. Replace any
worn parts.
• Controls and sensors. Once per year, the sensors should be
recalibrated against an accurate psychrometer. The sensors
do not have a calibration potentiometer. Sensor calibration
settings are found under the Service Settings menu on the
controller.
