Page 9 - PRODUCT OPERATION; THEORY OF OPERATION; REMOVING UNWANTED HUMIDITY
2-1 PRODUCT OPERATION THEORY OF OPERATION WHAT IS HUMIDITY? Humidity is defined as the amount of water va-por in the air and is measured as a percentage of the amount of water vapor the air can hold at a given temperature. When the amount of water vapor exceeds 100%, the moisture can no longer remain...
Page 10 - OPERATING CHARACTERISTICS; TYPICAL OPERATION; LOW TEMPERATURE OPERATION; ELECTRONIC CONTROL SENSORS
2-2 OPERATING CHARACTERISTICS When a dehumidifier begins its run cycle, a partial frosting of the evaporator can be ob-served. This temporary frosting is limited by the operating conditions of the unit. In all cases, the frost should completely disappear within 10 to 15 minutes.In cool dry conditions...
