Instruction manual

condensate connection to ensure proper drainage. Make sure that
the outlet of the trap is at least 1 in. lower than the drain-pan
condensate connection to prevent the pan from overflowing. Prime
the trap with water. When using a gravel apron, make sure it slopes
away from the unit.
If the installation requires draining the condensate water away
from the unit, install a field-supplied 2 -in. trap at the condensate
connection to ensure proper drainage. Condensate trap is available
as an accessory or is field-supplied. Make sure that the outlet of the
trap is at least 1 in. lower than the unit drain-pan condensate
connection to prevent the pan from overflowing. Connect a drain
trough using a minimum of field-supplied 3/4-in. PVC or field-
supplied 3/4-in. copper pipe at outlet end of the 2-in. trap. (See Fig.
12) Do not undersize the tube. Pitch the drain trough downward at
a slope of at least 1 in. every 10 ft. of horizontal run. Be sure to
check the drain trough for leaks. Prime the trap at the beginning of
the cooling season start-up.
VII. INSTALL ELECTRICAL CONNECTIONS
WARNING: The unit cabinet must have an uninter-
rupted, unbroken electrical ground to minimize the pos-
sibility of personal injury if an electrical fault should
occur. This ground may consist of an electrical wire
connected to the unit ground lug in the control compart-
ment, or conduit approved for electrical ground when
installed in accordance with NEC, ANSI/NFPA Ameri-
can National Standards Institute/National Fire Protection
Association (latest edition) (in Canada, Canadian Electri-
cal Code CSA C22.1) and local electrical codes. Failure
to adhere to this warning could result in serious injury or
death.
