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.Sharp edges may cause serious injury from cuts. Use care when cutting plenum openings and handling duct work.

3.Dropping may cause personal injury or equipment damage. Handle with care and follow installation instructions.

CAUTION

1.Read all instructions before beginning installation.

2.Improper installation may cause property damage or injury. Installation, service, and maintenance must be performed by a qualified service technician.

3.Do not use solvents or cleaners on or near the circuit board. Chemicals can damage circuit board components.

4.Wait 24 hours before running the unit if it was not shipped or stored in the upright position

INTRODUCTION AND COMPLIANCE STATEMENT

The Model 8191 and 8192 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..

High temperature limits can be set on the control to prevent bringing in outdoor air during the hottest period of the day.. The built in control will automatically compensate for the ventilation time that is missed by bringing in additional outdoor air during cooler periods of the day.. Compliance with the requirements of ASHRAE 62..2-2010 is met as the control adds ventilation time as needed to account for the fractional on-time and effectiveness of the ventilation schedule.. The control will also ensure that ventilation occurs no less than one hour of every four.. When properly installed and set, the Model 8191 and 8192 Ventilator with Dehumidification will meet the mechanical ventilation requirements of:

Energy Star Certified Homes, Version 3 EPA Indoor airPLUS, Version 1

DUCT COLLARS

STANDARD BASEMENT AND ATTIC INSTALLATIONS (FULLY DUCTED)

•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..

•The outlet duct collar may be attached to the top or end of the unit.. Move the outlet cover to the location not being used.. See

Figure 2..

•Make sure there are no bends in the ductwork coming off the outlet for a minimum of 4”.. This will ensure that the ductwork will not interfere with the backflow damper function..

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:

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..

4.Keep the control in the unit and relocate to the front access hole..

5.Secure the control with the same four screws used to attach the control to the top of the unit..

6.Secure the control panel cover to the top of the unit..

LOCATION CONSIDERATIONS

•Allow sufficient clearance for filter removal and to prevent airflow obstruction

•Electrical service access will require the removal of the side panel shown.. Allow sufficient space for service on this side of the unit..

•For attic installations, it is recommended that the ventilator be suspended..

•Always install the ventilator in a condensate pan when locating in or over a finished space..
