AIR CONDITIONING MODULE OPTIONS
STD = Standard equipment
CCM Compressor control module has adjustable 30 second to 5 minute delay-on-breaktimer. On
initial power up, or any time the power is interrupted, the delay-on-make will be 2 minutes plus
10% of the delay-on-break setting. There is no delay-on-make during routine operation of the
unit. The module also provides the lockout feature (with 1 retry) for high and/or low pressure
controls, and a 2 minute timed bypass for low pressure control.
HPC
High pressure control is auto reset. Always used with compressor control module (CCM)
which is included. See note
.
LPC
Low pressure control is auto reset. Always used with compressor control module (CCM) which
is included. See note
.
LAC
Low ambient control permits cooling operation down to 0°F.
CAUTION
During the initial firing of the burners there will probably be some amount of smoke issued to the
circulating air stream as the result of residual oil burning off of the heat exchanger tubes. This oil
is required during the forming process of the stainless steel heat exchanger tubes to facilitate the
bending. OSHA or the National Toxicology Program does not list the oil as a carcinogen. In vapor
form this may be irritating to the eyes or could cause headaches. This is a one-time occurrence,
and ventilation of the space may be required depending upon the space being conditioned.
