Crestron MMK-9L & WMKM-9L Mud Mount Kits

Mud Mount Kits: MMK-9L &
WMKM-9L

Description

Mud Mount Kits are the preferred method of mounting the Crestron Isys®
TPMC-9L 9” Wall Mount Touchpanel when the cutout made in the drywall for
touchpanel installation is too large. These kits provide support for additional
plastering that can be applied to hide large irregularities in the touchpanel cutout.

NOTE: If mounted into a material other than drywall (for example, wood lectern,
concrete or rock) use the cutout template, available in the post-construction kit
WMKM-9L. For concrete and rock mounting material, allow for proper ventilation
before mounting the touchpanel.

There are two Mud Mount Kits. The MMK-9L is an optional accessory for the
BB-9L back box and PMK-9L pre-construction mounting kit. Pre-construction refers
to framed walls prior to hanging drywall. It is designed to compensate for drywall
cutout imperfections, providing a grated surface suitable for the application of
drywall compound for a finished appearance.

The WMKM-9L mounting kit provides a quick solution for installing a TPMC-9L 9”
Wall Mount Touchpanel display in an existing wall or similar flat surface (e.g.,
lectern or podium). The WMKM-9L is designed with a mounting plate so it can be
mounted without the support of a stud. Designed for post-construction applications,
the WMKM-9L includes an MMK-9L mud ring to compensate for drywall cutout
imperfections.

NOTE: If necessary, consult the latest version of the TPMC-9L Operations &
Installation Guide (Doc. 7030) for a complete list of mounting options. The
document is available from the Crestron website (www.crestron.com/manuals

).

Crestron MMK-9L & WMKM-9L Mud Mount Kits

Setup

Supplied Hardware

The MMK-9L consists of three parts. These parts produce an assembly that attaches
to the BB-9L or PMK-9L. The WMKM-9L consists of six parts, three of which
make up the MMK-9L, as well as a mounting plate, cutout templates and mounting
screws.

The mounting plate provides the necessary support for a touchpanel in an existing
wall or similar flat surface (e.g., lectern or podium) which can have joint compound
applied to it. Two overlay cutout templates (4511894) are supplied. One is in the
shape of the required opening; the other is similar to a frame, with the inner area of
the frame the shape of the required opening. (Refer to the illustrations on page 3).
Use the template that is most convenient.

The hardware supplied with the MMK-9L and WMKM-9L is listed in the following
table.

Installation

This section provides an installation procedure for each Mud Mount Kit. The
“MMK-9L Procedure” starts below and the “WMKM-9L Procedure” starts on page

7. Be sure to review each procedure before starting.

MMK-9L Procedure

This section provides the necessary steps for the assembly of the MMK-9L with
either the BB-9L or PMK-9L (both sold separately). It is assumed the BB-9L or
PMK-9L has been secured to the stud according to the instructions in the latest
revisions of their Installation Guides (Doc. 7031 and Doc. 7032 respectively). It is
also assumed that drywall is in place and a cutout is made in the drywall along the
inside of the mounting plate for touchpanel installation.

Complete the steps in the order provided. The only tools required and not supplied
are four standard drywall screws (#2 Phillips flat head screws), a #2 Phillips
screwdriver, a level and tools/material to apply drywall joint compound.

CAUTION: Allow an air gap of at least 12 inches (305 mm) in the wall cavity
above and below the touchpanel for heat dissipation.

Crestron MMK-9L & WMKM-9L Mud Mount Kits

NOTE: The MMK-9L has been optimized for mounting in 5/8” (15 mm) drywall.
You may use 1/2” – 1” (13 mm – 25 mm) without issue. Thinner or thicker drywall
will cause issues with the installation.

NOTE: The illustrations in this procedure show the installation of the MMK-9L
with the PMK-9L. Even though the illustrations only show the PMK-9L, the
procedure is identical for the BB-9L.

1. Pass an adjustment plate through the opening and align its two center holes
with the top two pins on the PMK-9L (or BB-9L). Verify the pins on the
adjustment plate are not between (facing) the adjustment plate and the
PMK-9L (or BB-9L). Refer to the illustration below for guidance.

(2028255)

2. Slide a push-on fastener over each pin of the PMK-9L (or BB-9L) to
loosely secure the adjustment plate and the mounting plate. Do not push the
push-on fasteners all the way down onto the pins. Slide them on enough to
keep the adjustment plate and mounting plate as one adjustment/mounting
plate assembly.

3. Use the second adjustment plate and repeat steps 1 and 2 using the lower
two PMK-9L (or BB-9L) pins.

NOTE: When installing into the PMK-9L, verify the 18 AWG bus wire
securing the cables for the touchpanel remains attached.

4. Insert the symmetrical mud ring plate into the opening, as shown in the
following illustration.

5. When the mud ring is in position, bend the top two flanges of the ring
upward and the bottom two flanges downward.

• If mounting into the PMK-9L, bend the flanges approximately 90

degrees.

• If mounting into the BB-9L, bend the flanges back as far as they can

go.

6. Use four standard drywall screws (length should not exceed drywall
thickness by more than 1/2” (13 mm)) to secure the mud ring plate to the
rest of the assembly. The screws pass through the clearance holes in the
PMK-9L (or BB-9L) and are secured in the extruded holes of the
adjustment plates.

7. Verify the mud ring plate is level.

NOTE: Do not over tighten screws. Doing so can rip the mud ring plate.

8. Use a #2 Phillips screwdriver and tighten the drywall screws by hand so
they slightly dimple into the holes in the mud ring plate.

9. Apply joint compound as needed to finish the cutout. Avoid covering the
four tapped mounting holes.

10. Run the necessary cables for the touchpanel and secure them behind the
drywall.

11. When the joint compound is dry, the TPMC-9L can be installed using the
four tapped holes in the PMK-9L or BB-9L. Refer to the latest revision of
the TPMC-9L Operations & Installation Guide (Doc. 7030) for details.
Refer also to the following comprehensive illustration.

compound.

CAUTION: Allow an air gap of at least 12 inches (305 mm) in the wall cavity
above and below the touchpanel for heat dissipation.

NOTE: The WMKM-9L has been optimized for mounting in 5/8” (15 mm) drywall.

You may use 1/2” – 1” (13 mm – 25 mm) without issue. Thinner or thicker drywall
will cause issues with the installation.

NOTE: Before installation, be sure to consider the needs of your particular
situation. For example, screw type may vary depending on the mounting surface, etc.
