possible compressor
damage, do not operate the
cooling system when outside
temperature is below 50° F

compressor manu-
facturer instructions for further
information.
NOTE: When cooling setting is
changed, thermostat may delay
up to five minutes before
turning on the air conditioner.
This delay protects the com-
pressor.
