To install Certified Series Robin Hood, select a location in the branch duct that services the room. (See Fig.1) For best results, it should be located 6-10 feet from the room register. Remove sufficient insulation from the duct to allow separating the duct at a joint. The following table shows the size section to be cut off the female end of the joint.

Install the Robin Hood in the space provided with the fan blades facing the room to be serviced. (See Fig. 2) If separating at a joint is not practical, separate wherever desired in the branch duct. You must "crimp" or make a series of 1" slits in the end of the cut duct closest to the main blower so that it can be tapered to fit into the female collar of the Robin Hood. The male crimped end of the Robin Hood will fit right into the other side of the cut section, closest to the room. (See Fig. 2) Secure your Robin Hood by wrapping duct tape around both ends. (See Fig. 2A)

          

To install in FLEX DUCT, simply slide the flex duct over each side of the Robin Hood and secure with duct tape or plastic straps. Support flex duct with sheet metal straps or hanger wire. Fan blades should be closest to room register. (See Fig. 3)

Power Control Options:

1. Connect directly to 110 Volt for continuous operation.
2. Wire through an ON/OFF switch located in a convenient place. (Example: A wall switch in the room to be served.)
3. Wire through a 110 Volt thermostat installed in the room to be served. (This provides for automatic ON/OFF temperature control.)
4. Wire in parallel to existing blower. Be sure motor is rated 110 Volt VAC, single phase 60 cycles. Blower motor controller cannot be a variable speed type, solid state speed control or any other type not designed for dual motor control. Motor controller should be rated for multiple motor loads.
5. Wire to 110 Volt through an auxiliary switch, (pressure or "sail" type) which will automatically energize Robin Hood whenever blower operates.
