Remove the screws securing the terminalbox cover plate located on the sideof the fan. All fan motor connectionsare pre-wired to an electrical terminalstrip. A 3/8" romex type cable restraintconnector will be needed to secure thewiring through the knockout provided onthe side of the terminal box.2. Bring incoming electrical service throughthe romex connector and the fanknockout. Be sure to place the connectornut over the wiring coming into theterminal box. There are two open portson the terminal strip. Using a smallregular screwdriver, tighten the neutral(white) wire of the incoming supply underthe open terminal strip port labeled"N". Tighten the line (black) wire of theincoming supply under the open terminalstrip port labeled "L". Since the fan motoris isolated within a plastic housing, grounding is not necessary.3. Secure the romex connector. Secure the incoming supply with theromex connector. Replace the fan terminal box cover. All fan motorand capacitor connections have been pre-wired from the factory. Noadditional fan wiring is necessary.Liquid tight wiring – Top View(For outside applications).Romex wiring – Top ViewELECTRICAL CONNECTION WIRING DIAGRAMSAll ModelsIf a Vent/Light combination kit is purchased, the VLC vent/lights aresupplied with a separate installation instruction replacing steps 1 through4.1. Select the grill mounting point within thearea to be ventilated. To ease installation,locations of framing beams within thewalls or joists supporting the ceilingshould be considered. Collar/damper isprovided with a perforated hanging strapfor attachment directly to a beam or joist.Allow sufficient space between the collar/damper and the beam to attach the ductwork. If the location of the grill does notallow direct attachment, a cross-membermounted to the framing should be used.2. Place the mounting collar/damper in theselected location and trace a circle ontothe surface. From the interior side of theroom, cut through the surface. Pleasenote: In order to assure a smoother finishwhen mounting through a sheetrock or tile type ceiling, it isrecommended that a razor knife be used to make the cut.3. From within the attic or crawl space, place the mounting collar into thehole until the edge of the collar is flush with the interior wall or ceilingSide view grill and collar.Mount CollarINSTALLING DG SUPPLY/EXHAUST GRILLsurface. Attach collar to the support beam with the 2" wood screwsprovided. Attach duct work. Secure using CB or FC clamps and/or ducttape. When installing the damper into rigid type ducting, FC clamps orduct tape should be used.PLEASE NOTE: When attaching flex duct to the collar/damper combinationand an immediate elbow is necessary, be certain that the elbow isinstalled with a "soft" bend to allow damper blades to operate properly.4. Snap the grill into the mounting collar/damper. Grill should be pushedtightly into place for an airtight fit. If there is a gap between the collarand the ceiling it should be caulked to avoid air leakage. For subsequentcleaning the grill can be pulled out and cleaned.Flexible Duct Installation HintsFlexible insulated duct is strongly recommended where allowed by localcode for bathroom exhaust applications, where ducting passes throughunconditioned space or where noise is a factor. Failure to use insulationcould result in excessive condensation buildup within the duct, and undesir-able sound levels within the room. For the quietest possible installations,Fantech recommends a minimum of 8' of insulated flexduct between anyexhaust grill and fan. When using flexible type duct work, duct should bestretched as tight and straight as possible. Failure to do so could result indramatic loss of system performance. Flexible duct should be connectedto the fan with CB type clamps or duct tape. All connections should be asairtight as possible to maximize system performance. |
