Typical Equipment Layout Specification & Duct Connection
Operation
The DH95 is designed to deliver dehumidified, filtered air to the living space, and is equipped with an onboard
humidistat and fan control and can be equipped with various accessories to enhance its operation, including a
remote humidistat, and your system may incorporate any or all of the described operational components
It is recommended that the indoor environment maintain a maximum relative humidity level of 50% to
60%. Other factors may dictate a relative humidity level different than the recommended, such as musical
instruments, antiques, books/papers, or special situations. Winter minimum humidity levels of 30-35% may
not be attainable without supplemental humidification (Humidifier), and may not be desired during times of low
outdoor temperatures.
System Variations:
Humidity Control - Standard
The system may be installed as free standing or incorporate ducting to an area or existing heating/cooling
system. Control is provided by Humidistat with a dial stem type adjustment built into the unit. Set the desired
humidity set point by turning the dial stem flat to the corresponding set point indicated on the face of the unit.
This humidity control unit will operate the compressor and circulation fan when the dehumidification system is
activated, working only when there is a call, or demand for dehumidification.
