All units with electric heat MUST have one
inch (25.4 mm) clearance on all four sides
of the duct ange on the unit and on all
four sides of the wall sleeve.
The 1" (25.4 mm) clearance MUST extend
on all sides of the wall sleeve and on any
extension added to the wall sleeve for the
rst 3 ft. (1 meter) from the air conditioner.

Electrical Connections

Failure to follow safety warnings exactly could result in serious injury, death, and/or
property damage.
Turn off electrical power at fuse box or service panel BEFORE making any electrical
connections and ensure a proper ground connection is made before connecting line
voltage.
Important
All electrical work must meet the requirements of local codes and ordinances. Work should be
done only by qualified persons.
ICE units may incorporate an internal crankcase heater for compressor protection. The crankcase
heater must be energized for at least 24 hours prior to starting the compressor.
Scroll compressors, like several other types of compressors, will only compress in one rotational direction.
The direction of rotation is not an issue with single-phase compressors since they will always start and
run in the proper direction. However, three phase compressors will rotate in either direction depending
upon phasing of power. Since there is a 50-50 chance of connecting power in such a way as to cause
rotation in the reverse direction, it is imperative to confirm that the compressor is rotating in the proper
direction at the initial field start-up of the system. Verification of proper rotation is made by observing
