Airow restriction devices such as lters shall not exceed the
rated maximum static pressure limits of the indoor unit fan
assembly.
Doing so will cause product malfunction.
Do not install this product outdoors or where it will be
directly exposed to coastal conditions.
Air from the ocean may cause the evaporator ns to corrode, which could
cause product malfunction, improper operation, and shorten the expected
useful life of the product.
Do not install this product in a location that is noise
sensitive. Provide additional acoustical treatment as needed.
The risk is occupants may be discomforted.
When installing refrigerant piping, consider pipe expansion
and use are connections when connecting.
Improper pipe installation may lead to pipe fatigue, failure, and a rapid
release of refrigerant, frostbite, suffocation, physical injury, and or death.
Verify the piping system has been properly evacuated
(<500 ppm), and the system’s refrigerant charge is correct
before commissioning and after any repair is made.
Improper system evacuation and/or an improper refrigerant charge may
cause product malfunction.
