CT150 15" LCD Monitor – Industrial
Mount Bezel Installation
Overview
The “Industrial Mount Bezel” is a user-installable bezel option for the CT150 15" LCD Chassis
monitor. When properly installed, the industrial bezel creates an IP 66 level seal between the bezel
and the touch screen on the display, providing ingress protection against dry and wet contaminants.
When properly integrated, both the bezel-to-touch screen seal (inner gasket) and the bezel-to-cabinet
seal (outer gasket) will provide an IP66 level of protection. This seal has been tested to IP66 sealing
standards by an independent laboratory. However, due to 3M’s inability to control the enclosure
surface quality and finish against which the outer gasket will seal, we cannot guarantee an IP66 level
of sealing in this location. Each integration is unique and one needs to ensure that the housing surface
against which the outer gasket will seal is reasonably smooth, planar and free from deep scratches
which radiate across the sealing band. The gasket used in this location is relatively soft and
compliant, and therefore is forgiving of minor surface irregularities. However, it is always preferred
to have the surface as smooth and planar as possible around the entire perimeter of the bezel to ensure
high seal integrity, as well as preventing torsion of the bezel (forcing it out of plane) during
installation. Generally, a surface finish comparable to that of an average counter top laminate is an
ideal sealing surface for this type of gasket.
Industrial Mount Bezel Part Number: 29368 - 15"

Bezel Installation Instructions
1. Place a soft, clean towel on a solid, flat work surface to prepare for the bezel installation.
2. If your CT150 monitor has another bezel on it, you must first remove the existing bezel from the
monitor prior to installation of the industrial bezel. If necessary: Place the monitor face down on
the protected work surface. Remove the bezel affixing screws from the back of the unit (screw
locations shown in figure 1 below) and gently separate the bezel from the display.
Figure 1 – Bezel screw locations
3. Unpack the industrial mount bezel from its box and plastic bag. You should note that there are
two gaskets mounted to the bezel at the factory. The inner gasket provides the ingress protection
seal between the bezel and touch screen. The outer gasket is installed to provide an ingress
protection seal between the larger diameter of the bezel and enclosure into which the monitor will
be mounted.

4. Inspect the bezel assembly. Confirm the presence and integrity of both gaskets. Confirm the
presence and integrity of 8 threaded studs on the outside diameter of the bezel. Confirm the
presence and integrity of 10ea.- I.D. threaded extensions on the inside diameter of the bezel. See
Figure 2.
Figure 2 – Part identification
5. The bezel is designed such that the frame piece immediately outside of the I.D threaded
extensions pilots on the outside of the monitor frame. Place the bezel “face down” on the
protected work surface with the studs and threaded extensions facing you. Loose-fit the bezel
onto the CT150 monitor by carefully lowering the chassis monitor into the bezel frame. Be
careful not to drop the monitor onto the bezel as damage to the monitor may result.
Note: There is no top or bottom to the bezel - either orientation is correct.

6. Loosely secure the bezel with the ten M3 x 12mm phillips screws provided as shown by the red
circles in the figure below. Install the four corner screws first to ensure that the bezel is seated
uniformly. Then install the six remaining screws. Install all of these screws only until you begin
to feel the resistance of the shoulder of the screw seating against its mating surface on the monitor
case.
7. Torque the screws. All bezel affixment screws need to be tightened to a torque of 7 in/lbs to
effect a proper seal. Utilize and repeat an alternating cross pattern as shown in Figure 3 until the
7 in/lb. torque rating is achieved at all screw locations. Do not over tighten the screws or you
may damage the chassis or the LCD display.

8. The eight studs on the outside of the bezel require an M5 nut. Due to the array of unique
installation possibilities, these are not provided by 3M.
