INSTALLATION
Back Load Cell
Front Load Cell
1/8” – 1/4” Clearance
Location
The scale should be installed in a location with a flat, level floor. Note that the weighing
platform will not sit completely against the floor. This will not affect the accuracy of the scale
as the weighing platform will settle to the floor when the patient is placed on the scale.
The front load cells of the weighing platform will be off the floor. The back
load cells must be sitting completely on the floor.
There should be 1/8” to 1/4” clearance between
the sides of the scale frame and the floor. This
clearance is required for the lift mechanism to
close completely. The included shims can be
used to raise the scale if there are slight
imperfections with the floor or wall mount
installation that sits the wall mount too low and
prevents the scale from closing completely. If
the wall mount is too high the back load cells
will not touch the floor when the weighing
platform is lowered. If the wall mount is too
high, the wall mount must be moved lower on
the wall or the scale will not function correctly.
NOTE: It may be necessary to remove any base molding/chair rail/wall guard or to remove a
section of the base molding/chair rail/wall guard to provide space to mount the scale in a true
vertical position. An alternative method would be to shim the wall mount away from the wall to
accommodate any base molding/chair rail/wall guard.

Step 2 – Install the Wall Mount
35 1/2”
Top Edge
to Floor
NOTE: Due to the various types of wall construction, no mounting hardware is
furnished with the scale. Appropriate mounting hardware suitable to the wall’s
construction will need to be obtained to secure the wall mount to the wall.
The wall mount allows the scale to be adjusted up or
down and left or right to accommodate floors that
may not be perfectly flat. This insures the accuracy
of the weighing platform and prevents undue stress
to the scale.
The wall mount should be secured to the wall using
mounting hardware suitable to the wall’s construction.
The six (6) holes (in groups of two, sixteen (16) inchs
apart) in the wall mount allow for 1/4" hardware to be
used to secure the wall mount to the wall.
1. Determine the desired location where the scale is
to be mounted.
2. With an assistant, place the wall mount against
the wall. Insure it’s level and 35 1/2” from the top
edge of the wall mount to the floor.
3. Mark the holes to mount the wall mount.
4. Remove the wall mount and drill the required
diameter holes for the mounting hardware used.
5. Fasten the wall mount to the wall.
