- COOLING, HEATING AND SOUND
SYSTEM APPLICATION DATA
The coils for both the indoor and outdoor units are not only
circuited and headered for optimum heating and cooling
performance, but also for ample subcooling during all modes
of operation. The sub-cooling permits the outdoor unit to be
mounted 60 feet over or under the indoor unit without any
danger of flashing liquid refrigerant during the heating or the
cooling cycle.
Refer to the REFRIGERANT PIPING table above for more
detailed information on refrigerant pipe limitations.
A = 1-3/8" OD Vapor Line
B = 1-1/8" OD Vapor Line
C = Intermediate Trap - only required when a riser exceeds
50 feet.
D = Inverted Trap - only required when the horizontal run to
the unit exceeds 25 feet.
