IMPORTANT SAFETY INSTRUCTIONSWARNING: TO REDUCE THE RISK OF FIRE. ELECTRICSHOCK, OR INJURY TO PERSONS, OBSERVE THEFOLLOWING:A. Use this unit only in the manner intended by the manufacturer. Ifyou have questions, contact the manufacturer.B. Before servicing or cleaning unit, switch power off at servicepanel and lock service panel to prevent power from beingswitched on accidentally.When the service disconnecting means cannot be locked, securelyfasten a prominent warning device, such as a tag, to the servicepanel.• Suitable for use with solid state speed controls.CAUTION: For general ventilating use only. Do not use to exhausthazardous or explosive materials and vapors.INSTALLATION INSTRUCTIONSWARNING: TO REDUCE THE RISK OF FIRE, ELECTRICSHOCK, OR INJURY TO PERSONS, OBSERVE THEFOLLOWING:A. Installation work and electrical wiring must be done by qualifiedperson(s) in accordance with all applicable codes and standards,including fire-rated construction.B. Sufficient air is needed for proper combustion and exhausting ofgases through the flue (chimney) of fuel burning equipment to preventback drafting. Follow the heating equipment manufacturer's guidelineand safety standards such as those published by the National FireProtection Association (NFPA), and the American Society forHeating, Refrigeration and Air Conditioning Engineers (ASHRAE),and the local code authorities.C. When cutting or drilling into wall or ceiling, do not damage electricalwiring and other hidden utilities.D. Ducted fans must always be vented to the outdoors.E. NEVER place a switch where it can be reached from a tub or shower.FOR BEST RESULTSWhen installing the Ventilator in a new construction site, installfan and ducting during the rough-in construction of the building. Inletgrille(s) should be installed after the finished ceiling is in place.To install a ventilator in an existing building requires access tothe attic area above the space to be ventilated.INSTALLATION IN A NEWCONSTRUCTION SITEMOUNTING1. Select a mounting site; Identify a mounting location that offersaccessibility with minimal duct run. Mount ventilator as far fromthe inlet grille as practical to minimize noise.NOTE: If used for dryer boosting the ventilator must be mounted atleast 12 feet from the dryer outlet. For gas fired dryers theventilator capacity (CFM) must not exceed the dryer’s fancapacity.2. Attach fan mounting bracket to the support joist using the woodscrews provided (Refer to Figure 1). For best performancevertical mounting is recommended, however any orientation isacceptable.3. Attach fan to the mounting bracket using the self threadingscrews provided (Refer to Figure 1). To ease attachment 1⁄16˝pilot holes may be used for the mounting screws.WIRING1. Run 120v AC house power wiring through switch box to junctionbox in ventilator housing.2. Remove ventilator junction box cover.3. Refer to Figure 2. Connect the house power wire (black) to theterminal marked LI. Connect the house neutral wire (white) to theterminal marked N. The fan housing is fully insulated and thereforeno grounding is required.4. Replace outlet box cover.5. Connect house power wire to the wall switch.NOTE: ALL WIRING MUST COMPLY WITH LOCALELECTRICAL CODES.DUCTING INSTALLATION1. Refer to Figure 3. Attach duct to ventilator inlet and outlet usingclamps, fasteners and/or duct tape. Observe the followingrecommendations for best results;A. Always minimize duct lengths and turns.B. When flexible ducting is used be sure that the duct is fullystretched and free of kinks or sharp bends.C. Use insulated ducting when passing through unconditioned spaces.D. When insulated ducting is used clamp or tape the inner vinyl core tothe inlet and outlet of the fan and tape the vapor barrier surrounding theduct insulation to the fan housing.E. Always install a damper at the inlet grilles.INSTALLATION INSTRUCTIONSREAD & SAVE THESE INSTRUCTIONS!In-Line FansMODELS: ILF120, ILF130, ILF250,ILF360, ILF 530FIGURE 1MOUNTING BRACKETJOIST OR STUDFAN MOUNTING
