4. Maintenance**
Airmax Aeration Systems are designed for low-maintenance and re-
®
quire minimal scheduled maintenance. Cabinet inlets and outlets should
be kept free of debris and weed growth allowing normal ventilation.
• Always unplug system before performing any maintenance
or troubleshooting.
• Always unplug system and refer servicing to a qualified
electrician when: cord is damaged or frayed, compressor, power
control, compressor fan, or other electrical components are producing
unusual noises or odors.
• Always use parts that are supplied or approved by Airmax
of other parts may result in poor performance and could create a
hazardous situation.
** Local environmental conditions may require more frequent
maintenance.
WARNING: Compressors are equipped with a thermal overload switch.
If temperature becomes high enough to trip the overload, the compres-
sor will shut down. It will then automatically start up when temperature
decreases as long as power is applied.
