CAUTION
• Do not use the PAA unit in special environments.
– Oil, steam, sulfuric smoke, etc. can significantly reduce the performance of the PAA
unit or damage its parts.
• Always lock the furnace disconnect switch, if present, in the open position prior to
servicing the PAA unit.
• When installing the unit in a hospital, communication station, or similar place, provide
sufficient protection against electromagnetic noise.
– The INVERTER equipment, private power generator, high-frequency medical equip-
ment, or radio communication equipment may cause the PAA unit to operate errone-
ously, or fail to operate. On the other hand, the PAA unit may affect such equipment
by creating electromagnetic noise that disturbs medical treatment of image broadcast-
ing.
• Make sure an auxiliary drain pan is installed to prevent occasional condensation from
damaging the building.
• When the room humidity exceeds 80% or when the drain pipe is clogged, condensation
may drip from the indoor unit. Perform collective drainage work together with the outdoor
unit, as required.
• When the ambient dew point temperature exceeds 75° F (24° C), dew condensation
may occur on the unit surface. Perform appropriate treatment to avoid dew condensa-
tion.
