1. Determine size of duct opening. Duct width depends upon model, frame & border type and number of slot. See Duct Dimensions D’ table (Page 7). Duct length is as ordered.

2. First install end frames and field assembled corner pieces in ceiling opening. Then cut side rails to length and install. Use alignment strips furnished with frame parts to connect side rails, corners and end frames to each other.

Note: When end borders are not to be used with diffuser, mounting frame ends are not furnished.

3. Use removable gauges furnished with frame parts to ensure proper fit of diffuser into mounting frame. Gauges snap into place between side rails as shown above. If mounting frame is to be plastered into place, use wood blocks to stiffen side rails and maintain correct inside dimensions.

1. Assemble diffuser with alignment pins as shown above. End borders or caps, where ordered, are attached at factory.

2. Install diffuser in ceiling. See Hanger Bracket Mounting Instructions (Page 4).

Note: Mounting frame is used only on Frame & Border Types 3, 4, 6, 7A, 7B, 11.

1. Message length of diffuser to be cut.

2. Mark MLF or MLRF for field cut. NOTE: If 6” or less is to be cut off, use Trimming instructions shown above. To ensure proper support of pattern controller deflector blades, there should be 7” or less between end of diffuser and next spacer. If after marking their is more than 7” between the field cut mark and the factory spacer, install field spacer.

If field spacer is required

3. Line up wholes on side of field spacer with predrilled holes in diffuser. Make sure field cut is between factory weld spacer and field spacer.

4. Installed tube through diffuser field spacer. Next install screws in both ends of the tube and tighten.

5. For MLF with pattern controllers, install screw through lower tab hole of field spacer and tighten into threaded channel on blade support bar.

6. For MLF with pattern controllers install additional spring clips on top of blade support bar. Place clip 2” from edge or directly behind spacer if space is in the way. See spring clip for detail, Page 4.

7. Insert 1/2”dowel in center of each controller. Insert wood blocks or dowels on outside of pattern controller. Wood support pattern controller when cutting through diffuser.

8.Cut MLF or MLRF with circular saw. Recommended metal cutting saw blade:
