[. . . ] AIR BOOSTER Model: AB-2 The Air Booster is designed to increase the flow of heated air or cooled air in branch ducts of a heating and central air conditioning system. The Air Booster, can also be used to improve the air flow of a gravity warm air furnace. [. . . ] (See Figure 1A or 1B) Figure 1A Figure 1B Figure 2A Figure 2B 3. Insert the Air Booster into the slot, making sure the fan blade Figure 3B points in the direction of the air Figure 3A flow. Position the Air Booster so the fan blade does not rub against the inside surface of the duct. Mark on the duct the location of the 6-hole positions in the base plate. Remove the Air Booster and drill 1/8-inch diameter holes through the duct pipe where indicated. (See Figure 2A) Before installing Air Booster into the duct pipe, fasten the outlet box onto the base plate with the #10-32 UNF screws and nuts provided. Secure the Air Booster onto the duct with the sheet metal screws provided. (See Figure 3A or 3B) Page 2 UNIT WIRING INSTRUCTIONS ELECTRICAL DATA VOLTS 120 VAC AMPS . 60 HZ 60 WATTS 35 RPM 3000 THERMAL OR IMPEDANCE PROTECTION YES A permanent wiring method must be used for power connection. It is recommended that a minimum size of 14 AWG wire o o for electrical supply connections and wiring should be suitable for 90 C (194 F) temperature. The Air Booster should be wired with an overcurrent protection device (fuse or circuit breaker) rated 15 amperes or less. Wiring method should be in accordance with the National Electrical Code and any local code requirements. (See Figure 4 for wiring diagram) This method allows for manual control of the Air Booster unit in the area desired. [. . . ] Periodic removal and cleaning of the Air Booster unit is recommended for forced central heating/air conditioning systems. Annual removal and cleaning of the Air Booster unit is recommended for gravity warm air heating systems not equipped with a return air filter. [. . . ]
