TO REDUCE OR AVOID THE HAZARDS OF ELECTRIC SHOCK AND FIRE:
• Use a dedicated AC 120V outlet only.
• Do not obstruct or cover the air intake or air outlet of the ventilation
system.
• Do not modify, repair or disassemble this system. These tasks
are to be performed by authorized serviced personnel only. Fire,
electrical shock and/or bodily injury may occur if these warnings
are not followed.
• To prevent injuries, do not operate the ventilation system, while
servicing or maintaining. There are impeller wheels turning at a
very high speed that must fully stop rotating prior to accessing
the inside of the unit.
• Always assess the operation of the ventilation system on how
it may interact with vented combustion equipment (ie. Gas
Furnace, Oil Furnace, Combustion, Appliances, etc.)
• Do not use for swimming pool/spa applications.
