3. Using an inclined manometer, determine the pressure drop across a dry evaporator coil. Since the moisture on an evaporator coil may vary greatly, measuring the pressure drop across a wet coil under field conditions would be inac- curate. To assure a dry coil, the refrigerant system should be de-energized while the test is being run. -
