ELECTRICAL CONNECTIONDo not connect power supply until fan is completely installed. Makesure electrical service to the fan is locked in “off” position.1. All units are suitable for use with solid-state speed control.2. This unit has rotating parts and safety precautions should be exercisedduring installation, operation and maintenance.3. CAUTION: “For General Ventilation Use Only. Do Not Use To ExhaustHazardous Or Explosive Materials and Vapors.”4. WARNING: To reduce the risk of fire, electric shock, or injury to per-sons-observe the following:a. Use this unit only in the manner intended by the manufacturer. Ifyou have questions, contact the manufacturer.b. Before servicing or cleaning, switch power off at the service panel andlock service panel to prevent fan from being switched on accidentally.c. Installation work and electrical wiring must be done by qualified per-son(s) in accordance with all applicable codes and standards,including fire-rated construction.d. Sufficient air flow is needed for proper combustion and exhaustingof gases through the flue (chimney) of fuel burning equipment toprevent backdrafting. Follow the heating equipment manufacturer’sguidelines and safety standards such as those published by theNational Fire Protection Association (NFPA), the American Society ofHeating, Refrigeration, and Air Conditioning Engineers (ASHRAE)and the local code authorities.e. When cutting or drilling into a wall or ceiling, do not damage electri-cal wires or other hidden utilities.f. Ducted fans must always be vented to the outdoors.g. Install fan at least five feet above the floor.h. This product is acceptable for use over a bathtub or shower wheninstalled in a GFCI protected branch circuit.i. NEVER place a switch where it can be reached from a tub or shower.5. WARNING! Check voltage at the fan to see if it corresponds to themotor nameplate.Guards must be installed when this fan is within reach of personnelor within seven (7) feet of working level or when deemed advisablefor safety.WIRING INSTRUCTIONSSTEP 1.Remove the screws securing the terminal box cover plate located on thefan motor mounting bracket. All fan motor and capacitor connections arepre-wired to an electrical terminal strip. A 3/8” romex type cable restraintconnector will be needed to secure the wiring through the knockout pro-vided on the side of the terminal box.STEP 2.Bring incoming electrical service through the romex connector and the fanelectrical service opening (Refer to 1” opening. Dimensions “G” & “H”). Besure to place the connector nut over the wiring coming into the terminal box.Move the capacitor to allow access to the terminal strip (see I-4). There aretwo open ports on the terminal strip. Using a small regular screwdriver,tighten the neutral (white) wire of the incoming supply under the open ter-minal strip port labelled “N”. Tighten the line (black) wire of the incomingsupply under the open terminal strip port labeled “L”. Connect the neutralwire to the ground connection on the terminal block.STEP 3.Secure the romex connector. Secure the incoming supply with the romexconnector. Place the capacitor back into the terminal box. Replace the fanterminal box cover.All fan motor and capacitor connections have been pre-wired from thefactory. No additional fan wiring is necessary.TROUBLESHOOTINGIf fan fails to operate, please check the following:1. Consult wiring diagrams (page four of these instructions) to insureproper connection.2. Check motor lead wiring, capacitor leads and incoming supply leads toinsure definite contact.3. If possible, use a meter to test for continuity across the fan motorleads. In order to do this, the capacitor must be disconnected (do nottest the capacitor-it will not meter continuity). If motor leads showcontinuity, consult manufacturer for a replacement capacitor.MAINTENANCE INSTRUCTIONS1. Since fan bearings are sealed and provided with an internal lubricatingmaterial, no additional lubrication is necessary.2. When using in a dryer boosting application, DISCONNECT POWERSUPPLY and check impeller periodically for lint buildup.No other maintenance is necessary.MotorWiring DiagramsNeutral(white)115V SupplyLine(Black) SPST SwitchSPST SwitchSPST SwitchMultiple Location Switching Wiring DiagramI-4MotorLeads115VSupplyGroundCapacitorCapacitorBrownBlackBlueGreen/YellowGround115VSupplyMotorSpeedControlCapacitorMotorBlack120V SupplyWhite Green GreenBrownBlackBlueWith motor speed controllerCapacitorMotorBlack120V SupplyWhiteBrownBlackBlueWithout motor speed controllerGreen Green
