Display Installation

WARNING: Exceeding the weight capacity can result in serious personal injury or damage to equipment! It is the installer's responsibility to make sure the combined weight of all components located on the K3 Series mount up to (and including) the display does not exceed 15 lbs (6.8 kg) per display for the K3F220, K3G220, K3F310, K3G310 and K3G320 mounts or 25 lbs (11.34 kg) per display for the K3F120 and K3G120 mounts.

CAUTION: Using screws of improper size may damage your display! Proper screws will easily thread into display mounting holes.

NOTE: Supplied screws (H, J and K) may not fit properly for all displays. See display's operating instructions for details.

IMPORTANT ! : When applicable, always install center display FIRST in order to prevent stand from tipping! If there are no center faceplates (K3F220 and K3G220), be sure to support opposite arm when mounting displays to prevent stand from tipping! If possible, mount displays to both sides simultaneously.

NOTE: Set height of lower center display prior to installing other displays. See Height Adjustment section for details. Center of display must be at least 18" above desk surface.

Flush Mounting Holes

1. Position faceplate in desired mounting position. Adjust as required before proceeding. See Height Adjustment section for details.
2. Using Phillips screwdriver, carefully install two M4 x 12mm Phillips pan machine screws (K) into the upper mounting holes on the display. Thread screws completely into display, then back out 3 complete turns. (See Figure 12)

(K) x 2 Center faceplate (array stand not shown for clarity)

1. Pick up and align display so that screws (K) (installed on the back of the display in the previous step) fit into the mounting holes on the faceplate. Lower the display firmly into place. (See Figure 12)
2. Using Phillips screwdriver, install two M4x12 mm Phillips pan machine screws (K) through the lower mounting holes on faceplate into the display. (See Figure 13)

Center faceplate (array stand not shown for clarity) (4 (K) x 2

5. Tighten all four screws (K). Do not over tighten!
NOTE: If roll adjustment is desired for center faceplate, do not tighten screws.
6. Repeat Steps 1-5 for other displays.
7. Proceed to Cable Management section.

Recessed Mounting Holes

NOTE: If faceplate does not fit into recessed area of display, proceed with the steps in this section.

1. Determine depth of recessed mounting holes relative to back surface of display (against which faceplate will contact).

2. Select proper length spacer and screw from table below:

NOTE: All spacers used should be the same length. If the recess depths result in multiple spacer lengths, then select the longer spacer.

IF recess DEPTH is: THEN use spacer: AND		screw:
3/8" or less L (3/8" long) J (M4 x 20mm)
More than 3/8" up to and including 3/4"	M (3/4" long)	H (M4 x 30mm)

CAUTION: Using screws of improper size may damage your display! Proper screws will easily and completely thread into display mounting holes.

1. Using Phillips screwdriver, carefully install two selected screws (J or H) through selected spacers (L or M) into the upper mounting holes on the display. Thread screws completely into display, then back out 3 complete turns. (See Figure 14)
2. Pick up and align display so that screws (K) (installed on the back of the display in the previous step) fit into the mounting holes on the faceplate. Lower the display firmly into place. (See Figure 14)

Adjustments

Pivot Adjustment

1. Array arms may pivot toward the front of mount up to 15^ per arm. (See Figure 16)

WARNING: Pivoting array arms toward the back of mount may cause K3 Series mount to tip over causing serious personal injury or damage to equipment! Do not pivot arms toward back of mount! (See Figure 16)
