4. Maintenance**
Airmax Aeration Systems are designed for low-maintenance and require 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
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 compressor will shut down. It will then
automatically start up when temperature decreases as long as power is applied.
5. Troubleshooting
IF COMPRESSOR IS NOT OPERATING:
ISSUE CHECK
Option 1: Check for power.
Cabinet fan is not running.
Option 2: GFCI circuit tripped.
Option 3: GFCI circuit not tripped.
Option 1: Check compressor for power.
Option 2: Check compressor capacitor wiring for frays
Cabinet fan is running.
Option 3: No capacitor wiring issues can be seen.
Option 4: Capacitor has been replaced.
IF COMPRESSOR IS OPERATING:
ISSUE CHECK
Option 1: No air leaks are audible in cabinet.
No bubbles at any diffusers.
Option 2: Compressor operating normally or making
Option 1: Check for leaks at all connections in line

EVERY 3-6 MONTHS – Air Filter: Clean/replace air filter.
Cooling Fan: Check to ensure cooling fan is operating. Hot air should be pulled from the cabinet, not blowing in.
Pressure Gauge: Mark pressure gauge upon initial start up. Check to verify pressure has not significantly risen above
or dropped below initial reading. Normal operation will range between 5-10psi.
Pressure Relief Valve: Check to ensure air is not escaping from valve and replace if needed.
EVERY 12-18 MONTHS – Maintenance Kit: It is recommended to install a maintenance kit every 12-18 months to
ensure optimum performance.
EVERY 24-36 MONTHS – Membrane Sticks: We recommend inspecting and/or cleaning the membrane diffuser
sticks every 24-36 months, or anytime the pressure gauge reading is significantly higher than normal or there is a
reduction in bubbles from the diffuser. To clean, use Airmax
LIKELY CAUSE
Compressor and fan are not receiving power.
Damage to electrical cord or low voltage from
power supply.
GFCI malfunction.
Compressor is not receiving power.
Wiring loosened or was damaged during shipment
or maintenance.

lose compression and needs maintenance kit.
Diffuser membrane damaged, diffuser plate fitting
broken or diffuser plate is flipped over.
Diffuser maintenance needed.
Bad pressure relief valve.
Compressor over-heating due to bad cooling fan.
Gauge of supply wires to circuit possibly
undersized or cabinet is plugged into
extension cord.
Air filter in need of replacement.
