SAFETY PRECAUTIONS 1. 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 XT150H 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.
FOR HVAC INSTALLER ONLY 1. Intended Application for Ultra-Aire XT150H Place the Ultra-Aire XT150H on supports that raise the base of the unit above the top of the flanges on the drain pan beneath it. Raising the Ultra-Aire XT150H will help the unit drain with gravity flow. Do not place the Ultra-Aire XT150H directly on structural building members without vibration absorbers or unwanted noise may result.
FOR HVAC INSTALLER ONLY The remote controls of the Ultra-Aire XT150H are powered by a low voltage circuit (24 Vac) and must NEVER contact or be connected to a high voltage circuit. The control wires leaving the Ultra-Aire XT150H and the remote control panels are numbered and colorcoded to prevent confusion. Some of the control wires leaving the Ultra-Aire XT150H may not be used with certain control panels and should be left safely disconnected with wire nuts taped onto the stripped ends.
FOR HVAC INSTALLER ONLY 3.4C Ducting for Fresh Air 3.4D Installation in a Basement or Crawlspace with an Existing Forced Air HVAC System Fresh air can be brought into the structure by connecting an insulated duct from outside to the 6" Ultra-Aire XT150H inlet and by turning on the fan switch or activating the humidity control (on units with the humidity control panel). Activate the ventilation timer on units with the ventilating and humidity control panel to bring in fresh air. Refer to Section 4.
FOR HVAC INSTALLER ONLY 3.4E Installation in an Attic with an Existing Forced Air HVAC System from outside to the 6" collar of the Ultra-Aire XT150H if you wish to provide fresh air ventilation. ALWAYS install a catch pan with a drain and/or float interrupt switch for condensate under the Ultra-Aire XT150H in an attic to reduce liklihood of water damage. 3.5 Quiet Installation Consider compression vibration and airflow noise during installation.
FOR HVAC INSTALLER ONLY Ventilation Timer/Humidity Control Panel (P/N 4024125) (Figure 2, p.7) 4.6D Ventilation Timer and Humidity Control WITH Fresh Air AND Motorized Damper 4.2 Humidity Control Adjustment Set the humidity control to the desired humidity level for the home. Turning the knob clockwise results in a drier setting. See the back of the control panel cover for set points. The dehumidifier will run continuously until the relative humidity (RH) is reduced to the humidity control dial setting.
FOR HVAC INSTALLER ONLY 4.4C Automatic or Manual Mode The ventilation timer allows six programs with each program having one “ON” and one “OFF” event. A program allows the user to turn the ventilation on at a certain day and time, then it allows them to turn the ventilation off at a certain day and time. Each of these programs can be repeated daily or weekly or during a specified block of days. All six of the programs operate independently of each other.

FOR HVAC INSTALLER AND HOMEOWNER Engage the A/C central fan during dehumidification 1. Disconnect the green wire that runs to the fan relay from the screw on the thermostat. 2. Connect the green wire that runs to the fan relay to the COM screw on the DEH3000 board. 3. Run a wire from the red wire screw on the thermostat to the NO (Normally Open) screw on the DEH3000 board. 4. Run a wire from the green wire screw on the thermostat to the NC (Normally Closed) screw on the DEH3000 board.
FOR HVAC INSTALLER ONLY AND HOMEOWNER DEHUMIDIFIER DEACTIVATES WHEN THE AIR-CONDITIONER IS RUNNING • The common wire on the thermostat transformer (black) needs to be wired with the yellow wire from the dehumidifier. After connections have been verified, this short test will confirm proper wiring. • The Yellow wire from the thermostat must be wired to the AC off sensor terminal. 4. Engage dehumidification operation by adjusting RH setpoint below ambient conditions. a.
FOR HVAC INSTALLER ONLY 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 ONLY 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 ONLY 6. Maintenance 7.2 Technical Description The Ultra-Aire XT150H uses a refrigeration system similar to an air conditioner's to remove heat and moisture from incoming air, and add heat to the air that is discharged (See Figure 15). 6.1 Standard Air Filter The Ultra-Aire XT150H is equipped with a pleated cloth air filter. This filter should be checked every six months.
FOR HVAC INSTALLER ONLY No dehumidification, compressor does not run but impeller fan runs with fan switch and ventilation timer OFF and humidity control turned to ON. 1. Defective compressor run capacitor (Sec. 5.6). 2. Bad 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). Unit removes some water, but not as much as expected. 1. Air temperature and/or humidity have dropped. 2.
FOR HVAC INSTALLER ONLY 5. Remove fan/bracket assembly by removing 3 screws from the bracket and inlet ring assembly. 6. Remove the defective impeller fan from the bracket and replace with it with the new impeller fan. 7. Reassemble the new impeller fan by reversing the above procedure. Note: There are two pins on the backside of the cabinet that must align with the two holes in the impeller fan support bracket. replace the run capacitor. 11.
FOR HVAC INSTALLER ONLY 7. Evacuate the system with a good vacuum pump and accurate vacuum gauge. Leave the pump on the system for at least an hour. 8. Operate the system for a short period of time, monitoring the suction pressure to determine that the suction filter is not becoming plugged. Replace the suction filter/drier if pressure drop occurs. If a severe running burn out has occurred, several filter/driers may have to be replaced to remove all of the acid and moisture. ventilation of the residence.
FOR HVAC INSTALLER ONLY The pump also contains a safety float switch. The white leads from this switch extend from beneath the pump cover. This switch should be installed in series with the field wire that connects the blue (#5) lead from the Ultra-Aire XT150H to the blue (#5) lead on the control panel. If the pump fails, this switch opens the compressor control circuit and stops water production before the reservoir overflows.
