blower pulley upgrade, an alternate hp motor (7 - 12 tons)
or the belt drive option (3 - 5 tons).
B. Self-priming condensate cover assists in priming a dry trap.
C. A sloped drain pan to prevent standing water in the drain
pan.
NOTE: The internal drain connection is not offered with the
sloped drain pan design on the 15 & 20 ton units.
D. Smoke detector terminal block provisions provide field-
wiring means for powering a 24VAC duct smoke detector
and a single set of normally closed contacts, which open to
shut down the unit upon detection of smoke. Although the
air conditioning unit is shut down when the smoke detector
alarms, the 24V power supply to the smoke detector is not
interrupted. Actual mounting means for the smoke detector
are not provided due to the wide variation in regulations
and codes.
CAUTION: Normal maintenance activity will require discon-
necting power to the unit. When the YORK sup-
plied terminal strip is used to provide 24V power to
a smoke detector; the smoke detector will not be
powered when the power supply is interrupted to
the unit. If the smoke detector is linked to separate
monitoring system that would detect this power
shutdown and report it as an alarm condition, do
not use the unit terminal strip to power the smoke
detector.
