Installation Guidelines - Single Housing - 3M Drive-Thru G5 Installation Manual

3M™ Drive-Thru System Model G5
C. Installation Guidelines - Single Housing
The microphone and speaker are contained within a single housing. Component installation is the same for both the microphone and the
speaker. The microphone and speaker must be separated from each other by foam.
• Ensure that the inside of the housing is clean and dry.
• Install the 3M™ Vibration Control Tape to the inside of the top and side walls of the housing
(Figure 4).
- Using a pair of scissors, cut one piece of tape to be approximately 1" less than the length
of the inside of the top wall. The four pieces of tape used for the side walls can be used
as is from the kit and do not require trimming.
- Peel and discard the release liner from the back of the tape.
- Center a piece of tape on the inside of the top of the housing. Locate the
position of the microphone (speaker) and center a piece of tape on the inner wall of the
housing centered with the microphone. Repeat for the opposite wall. Repeat this step for
the speaker.

• Install the TUFCOTE
tape (Figure 5).
Standard method:
- Cut one piece of foam to be positioned between the speaker and microphone. In order
for the foam to fit securely, cut it slightly larger than the innerdimensions of the housing.
It should fit snugly between the walls of the housing without buckling.
- Check the fit of the faced foam to the inside of the housing, in the areas
adjacent to the microphone and the speaker. Cut into individual pieces to fit
the inside of each wall of the housing as shown in the illustration.
Alternative method:
- Form one piece of insulation into a "u" shape and position it in the upper pan of the
housing.
- Form the second piece of insulation into an upside-down "u" shape and position it in the
lower pan of the housing.
- Peel and discard the release liner from the back of the faced foam.
- Align the center of the foam with the centerline of the top wall of the cavity and then
work toward the edges until the foam is centered on the inside of the top and side walls
of the cavity.
- When positioned correctly, press the foam firmly to secure it in place.
• Install the Thinsulate™ Acoustic Insulation (fig. 6)
- Loosely line the housing with the acoustic insulation. For the best appearance, position
the black side of the insulation toward the outside of the housing.
- If there is excess insulation, overlap it against the inside of the first layer.
