Apply the mounting template provided to the duct, cut opening and drill four 5/16" holes noted on template. NOTE: If installing the DUCT BOOSTER® on a flat duct, the housing flanges will have to be bent at a 90 O angle before inserting DUCT BOOSTER® into duct. This will allow screws to better align with the speed clips provided. WIRING DUCT BOOSTER ® IN PARALLEL WITH HEAT CYCLE OR COOLING/BLOWER "ON" CYCLE 2. Attach speed clips to vent pipe and align with four holes drilled in step 1. 3. Insert DUCT BOOSTER® in the slot with the adjustable damper curved plate above blower wheel pointing in the direction of air flow.

INSTALLATION RESTRICTIONS Do not install the DUCT BOOSTER® where temperatures of air within the duct exceed 200 OF. This temperature would only rarely be found on a forced warm air system but could exist close to the furnace on a gravity warm air system. Locating the DUCT BOOSTER® near the outlet end of a duct will provide the most efficient performance. The DUCT BOOSTER® must be installed with the motor shaft horizontal. It can be installed on the bottom or top of a horizontal duct or any side of a vertical duct. Failure to install, maintain and/or operate the DUCT BOOSTER® in accordance with manufacturer's instructions may result in conditions which can produce bodily injury and property damage. Disconnect power supply when making wiring connections and servicing the DUCT BOOSTER®. Failure to do so may result in personal injury and/or equipment damage. [. . . ] The basic furnace wiring and components should not be disturbed except for wiring interconnection of the DUCT BOOSTER® and furnace blower motor at a splice box in the furnace. The rating of furnace blower motor controller must be adequate to control blower motor and the DUCT BOOSTER® motor. NOTE: Blower motor controller should not be a variable speed tap type, solid state speed control or any other type not suitable for dual motor control. The existing short circuit and ground fault protection for the furnace blower motor should be of a size and type which will adequately protect the DUCT BOOSTER® motor. [. . . ]
