INSTALLER’S & OWNER’S MANUAL HVAC INSTALLER: PLEASE LEAVE MANUAL FOR HOMEOWNER Dehumidification The highly efficient Ultra-Aire 100V dehumidifier utilizes refrigeration to cool the incoming air stream below its dew point. This cooled and drier air is used to pre-cool the incoming air stream resulting in a significant increase in overall efficiency. After the pre-cooling stage, the processed air is reheated by passing through the condenser coil.

SAFETY PRECAUTIONS Safety Precautions Read the installation, operation and maintenance instructions carefully before installing and operating this device. Proper adherence to these instructions is essential to obtain maximum benefit from your Ultra-Aire indoor air quality system. READ AND SAVE THESE INSTRUCTIONS • The device is designed to be installed INDOORS IN A SPACE THAT IS PROTECTED FROM RAIN AND FLOODING. • Install the unit with space to access the front panel for maintenance and service.
FOR HVAC INSTALLER ONLY 1. Intended Application for Ultra-Aire 100V the control wires leaving the Ultra-Aire may not be used with certain control panels and should be left safely disconnected with wire nuts taped onto the stripped ends. Be sure to consult the electrical schematic in this manual or on the front panel of the Ultra-Aire before making the control connections.
FOR HVAC INSTALLER ONLY a separate supply duct from the Ultra-Aire to each isolated area is recommended. DO NOT draw air directly from the kitchen, laundry, or basement. All flexible ducting connected to the Ultra-Aire should be UL listed. to 125 CFM of outside air. Large quantities of outside air will impact Ultra-Aire performance positively or negatively, depending upon the difference between inside and outside air conditions.
FOR HVAC INSTALLER ONLY Connect a duct from outside to the 6" collar of the Ultra-Aire if you wish to provide fresh make-up air. 3.4G Installation in a Structure with No Existing Forced Air HVAC Systems Crawlspace Installation: Locate a separate return for the UltraAire in a central area of the structure. Duct the supply of the Ultra-Aire to a 8" x 8" x 8" tee/damper that is 30% open to the crawlspace. Duct the other side of the tee to the air return of the existing HVAC system.
FOR HVAC INSTALLER ONLY 4.2 Ventilation Timer and Humidity Control Panel dehumidification or when the ventilation timer calls for ventilation. See Figure 2: The ventilation timer and humidity control panel automatically controls both the ventilation and the humidity of the living space. The ventilation timer and humidity control panel contains an adjustable humidity control, a fan switch, and a ventilation timer. This panel will control the humidity and allow 4.
FOR HVAC INSTALLER ONLY and the number “1” should remain in the lower right hand corner of the display. The “1” and “OFF” signify the turn off time for the first program. Set the turn off time using the 1…7, h, and m buttons in the same way as described above and continue on to the second through sixth programs. When setting the ventilation programs, you can return to the current time display by sliding the switch in the upper right corner of the timer to RUN.

FOR HVAC INSTALLER AND HOMEOWNER 8. Verify additional optional control operations such as fan interlock or lockout. 9. Proceed to operation/setting section. FOR INSTALLER & HOMEOWNER: 5.3 Operation 5.3A Display • When there is power to the control, the control display will show the time, day, humidity, and temperature. • When the control is turned on, the setpoint, fan status, auto/hold mode, and fresh air vent status is displayed. • When a key is pressed the display will light.
FOR HVAC INSTALLER ONLY AND HOMEOWNER Operation The initial dead band setting (the range that the dehumidifier cycles on and off) is 3%. With a setpoint of 50%, the dumidifier turns on when the reading reaches 53%. The dehumidifier continues to remove water from the air until the reading is 47%. The dehumidifier remains off until the reading is 53%. continuously are filtration and air recirculation. “AUTO” – indicates the fan will run when the control calls for dehumidification or ventilation.
FOR HVAC INSTALLER ONLY AND HOMEOWNER The ventilation indicator “O” will be displayed whenever the unit is ventilating. The fan operation indicator “O” will also be lit. There are two programs available for ventilation Monday through Friday. There are also two programs for Saturday and Sunday. No other choice of days is available. There are three damper operation modes, “OPEN – hold,” “CLOSED – hold” and “PROGRAM” (denoted by “ON TIME” – “OFF TIME.” Refer to section 3.8).
FOR HVAC INSTALLER AND HOMEOWNER 2. Press the program enter key to toggle to the “open for” setting. Using the up/down “RH” keys, change the duration that the damper will ventilate fresh air. feature will not need to be used. If temperature cutout is desired, program the setpoint by pressing the “program enter” button. Press RH until “temp cutout” is flashing. Use “RH” up or “RH” down to adjust setpoints. 3. Press the program enter key to toggle to the “closed for” setting.
FOR HVAC INSTALLER AND HOMEOWNER 6. Maintenance 7. Service CAUTION: Servicing the Ultra-Aire with its high pressure refrigerant system and high voltage circuitry presents a health hazard which could result in death, serious bodily injury, and/or property damage. Only qualified service people should service this unit. 6.1 Standard Air Filter The Ultra-Aire is equipped with a pleated cloth air filter. This filter should be checked monthly.
FOR HVAC INSTALLER AND HOMEOWNER No dehumidification, compressor does not run but fan runs with fan switch and ventilation timer OFF and humidity control turned to ON. 1.Defective compressor run capacitor (Sec. 5.6). 2.Loose connection in compressor circuit (See Fig. 4). 3.Defective compressor overload (Sec. 5.6A). 4.Defective compressor (Sec. 5.6). 5.Defrost thermostat open (Sec. 5.8). left in the system, it must be recovered before weighing in the new charge.
FOR HVAC INSTALLER AND HOMEOWNER 6. Compressor terminal C and overload terminal 1: No continuity indicates a defective overload lead. 7. Overload terminals 1 and 3: If there is no continuity, the overload may be tripped. Wait 10 minutes and try again. If there is still no continuity, it is defective and must be replaced. 8. Compressor terminal C and compressor case: Continuity indicates a grounded motor. The compressor must be replaced. 9. Disconnect the wires from the run capacitor.
FOR HVAC INSTALLER AND HOMEOWNER 7.9 Electric Ventilation Damper point. It opens when the RH drops 4 to 6% below the set point. If the Ultra-Aire does not run, try turning the humidity control clockwise until it reaches the stop and the knob pointer points at “ON”. The electric ventilation damper is controlled by the ventilation timer. The damper will open when the ventilation timer is activated to allow fresh air into the structure through the 6" diameter fresh air inlet duct.
