Installation

1. Note the rear diameter of your instrument. If mounting 2 or more
instruments side by side ensure the center points are;
A) apart by at least 1/2” more than the instrument rear diameter;
B) at least half the diameter (radius) plus 1” (25mm) below any
ceiling, shelf or other overhead obstruction; and
C) half the diameter (radius) plus 1/4” (6mm) above any lower shelf,
floor or table fixture.
Otherwise Slide ‘n Lock dovetail engagement cannot be made. If mixing
units of different sizes calculate horizontal center distance based on
the largest unit you intend to use.
2. Also ensure the center points are at least half the diameter (radius)
plus 1/4” (6mm) away from any side obstruction or corner.
3. If mounting 2 or more units vertically above one another, review items
1 & 2 (this section) regarding clearances to top, side and bottom.
Multiple center points must be at least one diameter plus 1/4”(6mm)
apart. If mixing units of different sizes calculate vertical center
distance based on the largest unit you intend to use.
IMPORTANT: Please read Additional tips section below
before continuing.
4. Place the mounting plate firmly on the center point ensuring that the
Weems & Plath logo and part number are upright. Align the 4 existing
recessed lines on the front face of the mounting plate with the pencil
lines previously marked on the wall or bulkhead.
5. Using a pointed tool or pencil, mark through 4 holes to position the
mounting screws on the wall surface.
6. Remove the mounting plate and drill the wall marks with a 3/32" or
2.00mm drill bit.
7. The mounting plate is designed with stepped mounting holes. The
smaller diameter facilitates accurate hole marking and avoids the
errors inherent in measuring or the use of a separate printed template.
The larger diameter is to receive the diameter of the screw thread.
8. As the screws are driven tight, the thin plastic forming the smaller
diameter hole will give way around the screw thread and form a tight
assembly.
9. Weems & Plath advises that on some wall materials such as
fiberglass, it is possible that the material around the drilled hole can
swell and displace forwards causing a volcano ridge around the
screw. This ridge will prevent the mounting plate from being screwed
tight to the wall. It is recommended after drilling the 4 holes that they be
countersunk creating a space to absorb any material displacement.
10. Secure the mounting plate in place with four No.8 round head stainless
steel Phillips screws supplied. These screws will displace the thin
plastic in the holes as they are driven home. Ensure the screws are
tight and the plate is firmly flat against the wall.
11. Place the instrument's back side above the mounting plate and position
on the vertical center line about ¾" (20.00mm) above the horizontal
center line and slide downwards to engage the dovetails
12. When resistance is felt press firmly downwards to cause the Slide 'n
Lock dimples to clip into place. (This is the reverse of step 1 above.)
This will hold the instrument firmly in place to prevent it from moving or
dislodging.
13. To remove the instrument for safe storage, calibration, adjustment or
battery change, reverse steps 8 & 9 of the installation procedure
