Maintenance Guidelines
• Keep your compressor and intake filter clean. Any excess dust and debris
on motor or air intake may significantly shorten the life of the compressor.
• Diffusers may need regular cleaning in certain water conditions. This may be
every two to five years.
• Compressors may need to be rebuilt if running but no longer “pumping air.”
Contact your EasyPro dealer for compressor rebuild kits.
• If lines become frozen, a small amount of denatured alcohol can be run
down the frozen line to thaw it out. The small amount of alcohol will not
harm fish or biological processes in your pond.
After one or two years of operation, you will possibly notice a sudden drop in air
bubbles. This is a sign the compressor needs new piston cup or vanes. Rebuild
kits are available to restore like-new performance. Be sure to keep the air filter
clean. Replacement filters are available.
