Introduction AND Compliance Statement The Model 8140NF Power Ventilator is designed to bring in precisely the right amount of outdoor air into today’s efficiently designed homes. Duct the inlet of the ventilator to an outdoor air intake and duct the discharge to the HVAC system and then simply plug the unit in, set the amount of needed ventilation and select the desired temperature limits.
PAGE 3
Ventilator Location and Orientation Choose a location for the ventilator that is within 6 feet of the outlet into which the ventilator will be plugged. The ventilator must be installed with the round inlet duct collar facing up or down, or the oval outlet collar must face up. DO NOT install with the outlet collar positioned as shown in Figure 2E or 2F, or the integral backdraft damper will not function properly.

Mount Intake Hood Install a weather tight hood with a bird screen. Cut a hole in the exterior wall that is large enough to fit 6” insulated flexible duct through with minimal compression of the insulation. Pull the duct through the hole and attach the flex duct to the collar of the hood. Use good quality duct tape or a plastic zip-tie to secure the duct to the collar. Pull the insulation and vapor barrier over the duct and tape it to the collar.

Wiring The ventilator will turn on when the HVAC equipment is running to distribute the fresh air to the home. When ventilation is needed but the HVAC system is not running, the ventilator can turn on the HVAC system blower. Run a 5-wire thermostat cable from the ventilator to the HVAC system control. Disconnect power to the HVAC system prior to wiring to the HVAC system controls.
PAGE 6
Set Up The control can be set up to prevent ventilation during the hottest or coldest periods of the day. When the outdoor temperature exceeds the high value or falls below the low value, ventilation will stop and additional ventilation will be brought in at a later time – See Start Up and Sequence of Operation for details. Figure 10 – Setting Temperature Limits 1. Remove the knob then remove the cover to adjust the high/low temperature limit. 2.

Measure Ventilation Air (CFM) Delivery Rate and Select Vent Time 1. Measure the outdoor air flow (CFM) through the duct that is bringing in only outdoor air. 2. Use the CFM Delivered along with the CFM required to find the Cycle Time per hour setting from Table 3. For example if the ventilator is providing 120 CFM, and the requirement is 70 CFM, set the time to 35 minutes. TABLE 3 – Cycle Time Setting (minutes) for Airflow Delivered vs.

Troubleshooting TABLE 4 – Troubleshooting Guide Symptom Possible Reason Correction Ventilator and display on control does not turn on. No power to the control. • Wire the control to the HVAC system as shown in the wiring diagrams on page 5. • Turn on power to the HVAC system. Ventilator does not turn on, but display on control is on. No power to the outlet into which the ventilator is plugged. • Turn on switch that controls outlet. E3 shows on display.
