Consideration should be given to installing a trap in the condensate drain line(s) so that normal discharge of condensate can fill
the trap and prevent the ingress of carbon monoxide (CO) or other potentially harmful vapors.
WARNING
Never install your air conditioner in the bilge or engine room areas. Ensure that the selected location is sealed from
direct access to bilge and/or engine room vapors.
Do not terminate condensate drain line within three feet (1 meter) of any outlet of engine or generator exhaust
systems, nor in a compartment housing an engine or generator, nor in a bilge, unless the drain is connected properly
to a sealed condensate or shower sump pump.
Failure to comply may allow bilge or engine room vapors to mix with the air conditioner's return air and contaminate
living areas which may result in injury or death.

WARNING
Electrical shock hazard. Disconnect voltage at main panel or power source before opening any cover. Failure to
comply may result in injury or death.
To minimize the hazard of electrical shock and personal injury, this component must be effectively grounded. Refer to
the installation guidelines for further information.
