CAUTIONS:
Manufacturer strongly recommends using two people
during installation of units.
Coil fins on chassis are sharp and chassis is heavy.
Please keep this manual handy for future reference.
Please note: In the summer; condensation (water)
run-off out the unit’s back is normal during cooling
operation under high humidity weather conditions. In
the winter; the unit is designed with a drain located in
the basepan to open at approximately SOT to minimize
formation of ice in the basepan during heating opera
tion. Unit should be installed where condensation
run-off will not drip on pedestrians or neighboring
properties. In addition it may be necessary to re-direct
drainage flow in the winter to prevent possible build-up
of ice on pedestrian walkways. To re-direct drainage
flow, an Accessory External Drain Kit is available.
Contact your independent Carrier Dealer or call
T800-CARRIER for information.
