WARNING
Install guidelines
• Read this manual carefully and follow all warnings and cautions provided with this unit.
Refer to your local building code and the latest National Electrical Code (NEC) NFPA
70. In Canada, be sure to refer to the latest Canadian Electrical Code CSA C22.1. Also,
follow all codes specified by your region.
We recommend installing a CO sensor and ventilation system.
– Failure to follow safety requirements can result in injury, death or building damage.
• When moving and reinstalling the PAA unit, consult the dealer, contractor or technician
with certifications required by laws and codes.
– If the air conditioner is installed improperly, water leakage, electric shock, or fire may
result.
• Ask a dealer, contractor or technician with certifications as required by laws and codes
to install the accessories.
– Improper installation by the user may result in water leakage, electric shock, or fire.
• Pay attention to the unit installation location. Refrigerant is heavier than air and locations
such as basements or crawl spaces where refrigerant can accumulate can become
dangerous.
– Inadequate ventilation can lead to poisoning.
• The appliance is not intended for use by persons with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge (including children) unless they
have been given supervision or instruction concerning the use of the appliance by a
person responsible for their safety.
• Do not add UV Lights into the PAA unit cabinet or to the attached ductwork.
– UV Lights can cause degradation to plastic and insulation parts. Water leakage, elec-
tric shock, or fire may result.
• If the gas furnace is not certified to safety standards (ANSI Z21.47/CSA2.3) by a nation-
ally recognized third-party certification organization (AGA, UL, CSA, ETL/Intertek, etc.),
or if the gas furnace does not comply with ACCA (Air Conditioning Contractors Associ-
ation) Standards and Guidelines (Code), NFPA54 (National Fuel Gas Code), NFPA70
(NEC: National Electrical Code), and if the equipment is not properly installed, used,
and maintained in accordance with the building code for each district (state, county, city,
town, etc.), the following hazards may occur even if our equipment is properly designed,
installed, and operated.
– If a leak sensor is not installed in the room, there is a risk of poisoning symptoms and
death without noticing a toxic gas leak.
– Gas fuel has an odor, but if you do not notice it, there is a risk that it can cause
poisoning symptoms or an accident, such as a fire or explosion.
– If the safety of gas furnace, gas supply piping, and exhaust duct worsen due to
improper ventilation of the system [ventilation must be in accordance with Law, Stand-
ard or Guideline (Code)], or due to aging deterioration or the influence of the usage
environment, there is a risk of poisoning symptoms due to combustion gas or igniting
fuel gas and causing a fire or explosion.
