Winter Operation
System owner assumes all risks with operating the Robust-Aire System during winter months.
Operating the Robust-Aire
® system during the winter or freezing temperatures may create open areas of water
at the diffuser locations. Also, ice will be thin surrounding those areas. Extreme caution should be used to avoid
injury or fatality from falling into the water. Signs to indicate the danger to others are recommended. Check your
local laws and ordinances as some areas require warning signs to be posted.
In climates where temperatures fall below freezing, it is recommended that you insulate the air lines from the
compressor cabinet a minimum of 3 feet into the water, at low water level. Using closed cell polyurethane foam
to insulate will prevent ice buildup in the lines. Ice buildup can block the flow of air to your diffuser and can
cause damage to your compressor. Insulation should pass through the ice, into open water below.
Moving the diffusers closer to shore in winter will allow a small area of the shoreline to remain open, preventing
winter kill.
Maintenance
Warning! Product surfaces become very hot during operation. Allow compressor to cool before
servicing. Disconnect electrical power before performing maintenance.
Check filter monthly; clean or replace intake filter when filter minder shows a red band. Reset by pushing the
small button on the minder top.
Failure to maintain clean air filter will lead to excessive heat and premature failure of the compressor.
