REFRIGERANT PIPING CONNECTIONS
Depending on the installation location, it could be necessary to in-
stall factory-supplied drain plug(s). See pages 13 to 16 for informa-
tion in reference to outdoor unit placement.
Do not use the drain hose on the outdoor unit In locations where it
can drop below freezing. Drain water from the defrost mode can freeze
and build up in the outdoor unit, impairing heating performance, and even
will damage the outdoor unit.
Installing Outdoor Unit Drain Plug / Piping
1. See diagrams at right for drain connection, drain caps, and drain
washer locations on the outdoor units.
2. If a drain hose is necessary, connect the drain hose to the drain
plug with the drain washer through the drain hole on the bottom
of the outdoor unit.
3. Connect field-supplied vinyl condensate piping to the outdoor
unit drain connection. If the field-supplied vinyl piping is too long,
position it to prevent kinks.
