    It next enters the evaporator coil where the refrigerant absorbs heat from the incoming air. The compressor then draws the cool refrigerant gas and compresses it to a high pressure and temperature to repeat the process. DryCool HD Operator and Maintenance Manual P00960167-1...
  • Page 4: Desiccant Wheel Operating Principle

    To avoid the problems often caused by moisture and create a comfortable environment, a dehumidifier is required or necessary to maintain relative humidity between 40-50% throughout the environment. Only supplemental dehumidification provides indoor humidity control regardless of air conditioner operation or outside moisture conditions. DryCool HD Operator and Maintenance Manual P00960167-1...
  • Page 5: Intended Application

    The DRYCOOL™ HD Dehumidifier is intended for installation in spaces that experience short or long term high humidity conditions. The DRYCOOL HD is not suitable for pool areas. Use of the unit in pool areas will void warranty. In order to efficiently control humidity levels, the area in which the dehumidifier is to be placed must be free of water intrusion or excessive fresh air infiltration.

    Simple Slow Time Weighing and Slow Time Weighing Sound Level Equivalent charts for the Drycool HD™ can be viewed in the Appendix. Unit sound level measurements were taken with system operating in the Airlab at Munters/Amesbury. Background sound measurements were taken before and after testing and represent the ambient noise levels at the time the system was sound level tested.
  • Page 10 The DRYCOOL™ HD plugs into a common grounded outlet on a 15 Amp circuit. It draws between 6 and 7 Amps under normal operating conditions. If used in a wet area, a ground fault interrupter protected circuit is required. DryCool HD Operator and Maintenance Manual P00960167-1...
  • Page 11: Ducting For Dehumidification

    Effective dehumidification may require ducting be branched to isolated, stagnant areas. Use 8" or larger diameter branch ducting to each of two or three areas; use 4" or larger to each of four or more areas. DryCool HD Operator and Maintenance Manual P00960167-1...
  • Page 12 The DRYCOOL™ HD is designed to move 250 cfm. An insulated 4"diameter duct is generally sufficient to provide up to 75 cfm of outside air.
