Safety Requirements
ELECTRICAL SHOCK, FIRE, OR EXPLOSION HAZARD.
If you do not follow these instructions exactly, a fire or explosion may result causing property dam age, personal
injury or death.
Failure to follow safety warnings exactly could result in dangerous operation, serious injury, death or property
damage.
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Installation and service must be performed by a licensed professional HVAC installer (or
equivalent), or a service agency.
Any additions, changes, or conversions required in order for the appliance to satisfactorily meet the application
needs must be made by a licensed professional installer (or equivalent) using factory-specified parts.
This unit must be properly grounded. The ground wire for the unit must not be connected to a gas or water pipe,
a lightning conductor or a telephone ground wire.
Do not use this system if any part has been underwater. A flood-damaged appliance is extremely dan gerous.
Immediately call a licensed professional HVAC service technician (or equivalent) to inspect the system and to
replace all controls and electrical parts that have been wet or to replace the system, if deemed necessary.
Refrigerant leaks are unlikely; however, if a refrigerant leak occurs, open a door or windows to dilute the refrigerant
in the room. Turn off the unit and all other appliances that may cause a spark. Call a licensed professional HVAC
technician (or equivalent) to repair the leak.
DO NOT spray water on the indoor unit for any reason.
Do not touch the unit or the controller if your hands are wet.
Do not replace a fuse with a fuse of a different rating. Do not use a jumper wire to replace a fuse.
Do not insert your hands, tools or any other item into the air intake or air outlet at either the indoor or outdoor
unit.
Do not remove the outdoor unit fan guard for any reason.
If outdoor unit is installed on a raised stand, check condition of stand occasionally to ensure that it remains
stable.
Do NOT install sprinklers or soaker hoses where they can expose the outdoor unit to treated water. Prolonged
exposure to treated water will corrode the surface of the steel and aluminum parts and will diminish the
performance of the unit.
Do not place items which may be damaged by water under or around the indoor unit.
Ensure that the condensate drain is properly routed to a drain.
