deflecting the flow of air from the fan frame

Installing Coil and Fan Assembly Frames
7.1 Before you stand up any of the frame assemblies, extend the
legs out to 5.0” (by spinning the foot pads).
7.2 Installing the Coil Frame Assembly
1. Remove the Coil Top Trim, 013121.
2. Install the coil frame into the appropriate side.
3. Center the frame within 1/16” between the two walls.
4. Install screws into the rear top back brace. This will force the
frame against the wall permanently.
5. Reinstall the top coil trim piece. Attach the grey plastic probe
receptacle box (from the controller) into the rectangular hole.
Orientation of the Trim Pieces
The Bally box design follows certain rules. One of the results is that a wall that two corners on it will be 1½”
narrower than a wall made of a corner and a breaker. As a result of this, there is more room in a NW1000 than a
NW500. To make up for this extra space, the trim pieces are turned with the long legs against the frame on a
NW1000, long legs against the walls on a NW500.
