SAFETY INSTRUCTIONS WARNING 1. 120 Volts may cause serious injury from electric shock. Disconnect electrical power before starting installation or servicing. Leave power disconnected until installation/service is completed. 2. Dropping may cause personal injury or equipment damage. Handle with care and follow installation instructions. 3. Sharp edges may cause serious injury from cuts. Use care when cutting plenum openings and handling duct work. CAUTION 1.

INTRODUCTION AND COMPLIANCE STATEMENT The Model 8192A Ventilator with Dehumidification is designed to bring outdoor air into today’s efficiently designed homes while removing moisture from the air. Simply duct the inlet of the ventilator to an outdoor air intake and duct the discharge to the return side of the HVAC system. Plug the unit in, set the amount of needed ventilation and set the humidity limit.

SET UP VENTILATOR FOR INSTALLATION IMPORTANT: Cut the strap securing the compressor shipping support bracket and remove the strap and shipping bracket. See Figure 1. FIGURE 1 – Remove Shipping Bracket REMOVE SHIPPING BRACKET CLIP OFF PLASTIC STRAP 90-1908 DUCT COLLARS STANDARD BASEMENT AND ATTIC INSTALLATIONS (FULLY DUCTED) FIGURE 2 – Duct Collar Locations • Use the screws in the parts bag to attach the duct collars to the inlet and outlet of the ventilator. The outlet collar has a backflow damper.

CONTROL LOCATION The on-board control can be located on the top of the ventilator or can be relocated to the front of the ventilator. To move the control: FIGURE 3 – Control Location CONTROL PANEL COVER CONTROL 1. Remove the front control panel cover. 2. Remove the filter access door and filter. 3. Detach the on-board control by removing the four (4) screws around the control. NOTE: Use one hand to support the bottom of the on-board control when removing. CONTROL CONTROL PANEL COVER 4.

DRAIN INSTALLATION The drain outlet on the dehumidifier can be hard piped using a 3/4” PVC Slip x 3/4” MNPT fitting and 3/4” nominal drain tubing or the provided 3/4” MNPT x 3/4” hose barb fitting. 3/4” clear PVC tubing can be used to drain the dehumidifier. Always maintain a constant downward slope from the dehumidifier to the drain and do not allow soft tubing to curl up which may result in air lock. NOTE: PTFE thread seal tape is recommended for the threaded connection and hand tighten only.
PAGE 7
LEVELING The feet can be adjusted to level the unit and accommodate drain fittings and secondary condensate pans as required. Refer to top mounted bubble level and adjust feet until bubble is within the outer circle. Leveling is required to ensure proper drainage from the dehumidifier. See Figure 6. FIGURE 6 – Level the Unit BUBBLE LEVEL 0.38" MIN 2.00" MAX 3/4" DRAIN 90-2592 CONDENSATE PAN, CONDENSATE PUMP AND FLOAT SWITCH Install a condensate overflow safety switch (i.e.

DUCTING AND WIRING DUCTING Install ducting as shown in Figure 8. A 6” diameter intake duct is usually sufficient, but a larger intake duct, or multiple 6” intake ducts can be used if added ventilation flow is needed.
PAGE 9
DETERMINE VENTILATION REQUIREMENTS CALCULATING AIRFLOW REQUIREMENT 1. The MINIMUM ventilation requirement is calculated using ASHRAE 62.2-2010. TABLE 1 – CFM Required ASHRAE Airflow in CFM = [House Area in Sq. Ft. x 0.01] + [(Number of Bedrooms +1) x 7.5] House Sq. Ft. OTE: Use ‘Number of Bedrooms + 1’ or ‘Number of Occupants’, N whichever is larger. 2. Table 1 shows the calculated airflow values to the nearest 5 CFM. 3. Record the required CFM.

SYSTEM SET-UP & CHECKOUT 1. Check all wiring. Model 76 Remote Control Option 2. Make sure the wire access cover has been snapped back onto the on-board control. If using the control on the ventilator, keep this feature DISABLED. 3. Plug unit in and turn power switch to ON. 4. The on-board control screen should display OFF. 90-1854 If using the Model 76 Remote Control to adjust the humidity setting, this feature should be ENABLED.
PAGE 11
DEH W/AC Installer Test Mode To allow the ventilator to dehumidify during active air conditioning, select ENABLED and press MODE. 90-1854 If everything is properly wired, the ventilator and all of the wired components will turn on and off during Installer Test Mode to demonstrate that all are properly operating. Installer Test Mode lasts for four (4) minutes. If the ON/OFF button is pressed during test mode, the ventilator will exit Installer Test Mode and return to the OFF screen.
PAGE 12
START UP AND SEQUENCE OF OPERATION Turn the ON/OFF switch ON, and turn on the control by pressing the ON/OFF button. The first press of any button only turns on the backlight, so the ON/OFF button may need to be pressed twice. The display will show the humidity control setting – use the UP/DOWN buttons to adjust as needed. A setting of one (1) is less dry and a setting of seven (7) is more dry (see NOTE ON HUMIDITY CONTROL SETTING below).
PAGE 13
MAINTENANCE CLEAN OR REPLACE THE AIR FILTER After initial installation the air filter should be checked and cleaned every 6 months. The CLEAN FILTER service reminder will display on the on-board control screen every 6 months. To clear the service message, press the UP and DOWN arrows simultaneously for 3 seconds. Filter Cleaning Procedure 1. Turn the ON/OFF switch OFF. 90-1854 2. Remove the filter access door from either side of the ventilator. 3. Slide the filter out of the ventilator. 4.
