COOL-DOWN TEST
This test has been designed for performance testing of the A/C system at the manufacturing facility. If the HVAC control module is replaced, the
Cool-down test will occur during Calibration test. Cool-down will not occur on Heater Only units. During the Cool-down test the control will
monitor the temperature of the Fin Sensor. The A/C system must be able to bring the evaporator temperature down a predetermined minimum
amount in less than 2 minutes.
