• Ensure that the lock valves of the outdoor unit are opened immediately after connecting
the PAA unit to the outdoor unit.

during the furnace's heating operation.
• Due to improper installation of PAA unit (drain pan of this product) or forgetting to install
the float switch, the condensed water of the PAA heat exchanger will deviate from the
specified path and may cause water to leak on to the heat exchanger of the gas furnace.
This may cause gas, oil, and water leakage from the furnace due to corrosion over time.
Furthermore, this can lead to poisoning, fire, explosion, water leakage, and bodily harm
and damage to property.
• When PAA unit (this product) is supported from the ceiling in a garage or an occupied
area, the product may fall due to insufficient strength of the suspension or support,
or deterioration over time, etc., causing bodily harm and damage to property. In some
cases, it can lead to death.
