Maintenance; Troubleshooting - Airmax Shallow Water Serie El Manual Del Propietario

5. 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.

®
CHECK
Option 1: GFCI circuit tripped.
Option 2: GFCI circuit not tripped.
Compressor is plugged in?
CHECK
Option 1: No air leaks are audible in
cabinet. Compressor running
louder and possible excessive
vibration.
Option 2: Compressor operating normally
or making unusual noises.
Exhibits reduced pressure and/
or air flow.
Option 1: Check for leaks at all
connections in line and in
cabinet. If none are audible,
carefully spray SMALL amount
of soapy water onto connections
and look for bubbles.
Option 2: Are all flow control valves in
compressor wide open?
Option 3: Valves in cabinet are properly
"balanced" and no leaks
are evident.
Inspect each diffuser plate for malfunction.

compressor is running.
Option 2: Check for clogged air filter.
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 cabinet, not cool air blowing in.
EVERY 12 MONTHS - Membrane Sticks: Purge membrane sticks. For SW20 & SW40, while compressor
is running, shut off all air flow valves except one, forcing all air to one diffuser plate for 10 seconds. Repeat for
each plate.
EVERY 6-12 MONTHS - Maintenance Kit: It is recommended to install a maintenance kit every 6-12
months to ensure optimum performance.
