1. 2. Check ductwork to see if the fan’s discharge requires rotation from horizontal to vertical discharge, shown in Fig. 2. 3. To rotate from horizontal to vertical discharge, remove the eight screws holding the cover panel as shown in Fig. 3a (for the CSP model remove the eight collar screws as shown in Fig. 4a). Then rotate the fan housing so the discharge is facing up, shown in Fig. 3b. Replace the cover panel as shown in Fig. 3b and replace the screws (for the CSP model attach the collar and its screws as shown in Fig. 4b). Fig. 4a WARNING ! To reduce the risk of fire, electric shock, or injury to persons, observe the following: • If a speed controller is used, this fan should only be used with fan speed control, manufactured by KB Electronics, Inc. • Before servicing or cleaning unit, switch power off at service panel and lock service disconnecting means to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag, to the service panel. • Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including firerated construction. • The combustion airflow needed for safe operation of fuel burning equipment may be affected by this unit's operation. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities. • When cutting or drilling into wall or ceiling, do not damage electrical wiring or other hidden utilities. • Ducted fans must always be vented to the outdoors. • For general ventilating use only. Do not use to exhaust hazardous or explosive materials and vapors. • These fans are not recommended for cooking exhaust applications. They are designed primarily for low temperature, clean air applications only. 1 Fig. 1 Knockouts Electrical Access Panel Airflow Airflow Fig. 2 Fig. 3a Fig. 3b Fig. 4b Access Panel Access Panel Access Panel Access Panel Collar Collar 1. If fan is to be used in a fire resistive membrane ceiling, a ceiling radiation damper must be used. Otherwise, proceed to Install the Fan. 2. If the ceiling radiation damper is already mounted to the fan from the factory, proceed to Install the Fan. 3. To mount the ceiling radiation damper to fan, make sure grille attachment tabs are facing down. Then place the inlet part of the fan into the ceiling radiation damper collar, and use self-tapping sheet metal screws (by others) to screw through the damper collar and into the fan housing, shown in Fig. 5. 2 Install the Fan Installation Recommendations 1. For best performance, choose a location with the shortest possible duct run and minimum number of elbows. Do not mount near cooking equipment. Fig. 7 shows the minimum distance these fans should be placed in relation to cooking equipment. 2. Attach adjustable mounting brackets to fan, but leave the screws loose until proper height is determined, shown in Fig. 8. For fan only opening, cut 233.4 x 113.4 inch hole in ceiling. For fan/CRD combination opening only, cut 241.8 x 121.4 inch hole in ceiling. For Frame Construction: Position unit between joists. Position brackets such that bottom edge of housing will be flush with finished ceiling, and tighten the adjustable mounting brackets, shown in Fig. 9. Do not install fan in this area 45. 45. Fig. 7 Top Mount Bottom Mount Brackets can be used in either position to adapt to most mounting situations Bottom Mount Fig. 8 Slots in the brackets allow fine adjustment for flush fit with wall/ceiling opening Fig. 9 Fig. 10 For Hanging Installations: Use Greenheck’s optional vibration isolator kit Part Number VI Kit. Using the fan’s standard adjustable mounting brackets and 10 by 32 threaded rod (by others), hang unit as shown in Fig. 10. Ceiling Radiation Damper - CRD Fig. 5 Do not allow interference in this area. 4. Slide ductwork over the fan’s discharge collar and securely attach it with sheet metal screws. Make sure the screws do not interfere with damper operation. Check damper to make sure it opens freely. 3 Wire the Fan 1. Remove wiring cover. Then wire unit to the correct installation type, shown in Fig. 12, using proper wire connectors. Attach the Grille 1. Attach grille with two screws provided, shown in Fig. 13. Make sure not to over tighten, over tightening will damage grille. 2. Turn on power and check fan operation. Fig. 13 Fig. 12 2. Push all wiring into the unit’s cover and replace wiring cover. 3. Installation of ductwork is critical to the performance of the fan, shown in Fig. 11. Straight ductwork (1) or ductwork that turns in the same direction as the wheel (2) is recommended. Ductwork turning opposite the wheel direction (3) will cause turbulence and back pressure resulting in poor performance. AIR FLO...
