Winter Operation and Deeper Ponds
If fish are present in the pond, place the diffuser between the shallowest and deepest
portion of your pond. For instance, if the deepest part of your pond is 6' and the
shallowest is 1', place diffuser in the 2' - 3' range for wintertime operation. This will
prevent the water at the deepest portion from being mixed with colder water.
Maintenance
1.
Always unplug unit before service, cleaning or any maintenance.
2.
Over time the compressors may need to have the diaphragm or piston replaced. See
chart below for compressor repair kits.
Troubleshooting
Loss of air output but unit is running:
•
Check to make sure the air filter has not been blocked or clogged by dust.
•
Check to make sure lines are not kinked or plugged. If used in winter time, line may
have ice in the line. A small amount of rubbing alcohol can be run down the air line to
thaw the ice.
•
Inspect the diffusers to ensure they are clean. Replace or clean as necessary. See
chart below for replacement diffusers.
•
Inspect diaphragms/pistons. Replace as necessary.

Caution:
•
During operation, do not touch the lower housing with bare hands as the temperature will
become about 70ºC (158ºF). (Temperature will not affect the performance of the pump.) Thermal
overload will turn off the compressor when temperature gets too high. Unit will come back on
after it cools down. Causes for excess heat should be determined and eliminated. Common
causes include lack of ventilation and excess back pressure in the system. Remedies for these
causes should be found to avoid over heating of the units.
•
Proper sizing and selection of tubing, length of tubing, number of diffusers and depth of
diffusers are all important factors for maximizing performance. These units are designed to
produce fairly large volumes of air at low pressure. Extra back pressure created by restrictive
tubing, undersized or clogged diffusers, incorrect valve systems or deeper water can cause
excess wear and tear on the rubber diaphragms. While replacing the diaphragms is easy to do,
too much back pressure may require more frequent repair.
