which are likely to produce corrosive or peculiar smell to prevent the smell from entering
indoors or corrupt the unit.
(2) It is not allowed to connect the condensate drain pipe into rain pipe to prevent rain water
from pouring in and cause property loss or personal injury.
(3) Condensate drain pipe should be connected into special drain system for air conditioner.
(4) The drain pan has primary and secondary drain connection. Condensate removal is
performed by attaching a 3/4” PVC pipe to the evaporator coil pan and terminated in
accordance with local or state Plumbing/HVAC codes. The installation must include a “P”
style trap that is located closely to the evaporator coil. Do not over-tighten the drain
connection in order to prevent possible damage to the evaporator drain pan. See the
following figure for details of a typical condensate line “P” trap.
