ASSEMBLY
STEP 1: Unpack the scale system and check parts
against the PACKING CHECKLIST. If there are
any missing or damaged parts, please call the
Service Hotline at: 1-800-654-6360.
STEP 2: Verify that the serial number on the label of
Wall Box Display matches that on Platform Base.
STEP 3: (Figure 1) Mount Wall Box Display into
wall and run the conduit, with connector cable
inside, down through wall and into pit as shown.
STEP 4: Prepare pit area to accept the Scale
Frame. It is recommended that a properly plumbed
drain be installed in the center of pit to avoid any
water buildup that might damage scale.
STEP 5: (Figure 2) Center the Scale Frame in the
pit using the supplied installation tabs to suspend the
frame in place (see “Pit Area Installation Notes”).
Pit Area Installation Notes
This is a rectangular frame so it is
important to check the placement
specifications to make sure the conduit
connection is properly placed facing the
wall where the conduit/cable connection
is located. There are holes cut for
conduit entry in the center of two sides
of the frame so the scale can be placed
with either the long or short side against
wall (Figure 3). Run conduit/cable
through hole and into pit area.
For 32” x 36” Platforms: If using
supplied installation tabs to suspend
frame while pouring concrete, pit
perimeter dimensions cannot exceed
44”x 48”.
For 32” x 50” Platforms: If using
supplied installation tabs to suspend
frame while pouring concrete,
perimeter dimensions of pit cannot
exceed 44”x 62”.
For 48”x 72” Platforms: If using
supplied installation tabs to suspend
frame while pouring concrete, pit
perimeter dimensions cannot exceed
60”x 84”.

ASSEMBLY cont’d
STEP 6: (Figure 4) Back fill around the perimeter of the Pit
Frame Assembly with 3000PSI concrete. Trowel the concrete
level with the scale frame and existing floor. Trowel the base of
the pit level with the base of the frame with a gradient toward the
centered drain, if used. Conduit and cable should be left free so
cable can be easily connected to the Platform Assembly.
STEP 7: (Figure 5) When the
concrete has set, remove and
discard the installation tabs and
screws. Install the four ¼” long
flat head screws into holes left by
plate removal.

STEP 8: Remove the Platform
Assembly from the Base Assembly
using a 5/32” hex wrench to remove
the four (4) mounting screws and set
aside.
STEP 9: (Figure 6) Place the Platform Assembly
into the Pit Frame Assembly. The cable connection
will plug into the connector on the platform base.
Ensure extra cable does not interfere with platform
top.

ASSEMBLY cont’d
Note: This scale is designed so that the Platform
Assembly is level with the Pit Frame Assembly. When
tiling or carpeting the platform deck, be sure to
compensate for the thickness of the material. Tiling
Tip: If tiling the floor, the use of an extra tile (or
something with the same surface height) is placed
under each of the four leveling feet of the pit frame.
This will bring the scale surface flush with the tiled
floor.
STEP 10: (Figure 7) Adjust the eight (8) Side
Clearance Adjustment Bolts, so that the Platform
Assembly is at an equal distance from all sides of the
Pit Frame Assembly. Tighten bolts to secure Platform
Assembly in place.
STEP 11: (Figure 5) Set the Platform Deck onto the
platform base and secure in place with the four (4) top
mounting screws. Allow 1/8” gap between Platform
Assembly and floor.
STEP 12: Install building ground wire and green ground wire from Display Front Plate into the
terminal lug in the wall box.
STEP 13: Connect Transducer Cable to the mating cable on the back of the Display Front Plate
STEP 14: Connect A/C power wires to the power supply wire leads

REPLACEMENT PARTS AND ACCESSORIES
SYSTEM DESCRIPTION
The SR463iR Series weight systems are precision digital scales specifically designed for installation in
the floor so the weighing surface is flush.
This scale system employs the latest in microprocessor and load cell technology to provide accurate
and repeatable weight data. Four (4) identically matched load cell transducers are strategically placed
to ensure an accurate representation of the patient’s weight regardless of weight distribution.
The SR463iR Series display units use 120v AC line power that is mounted in a recessed wall box so
the display is flush with the wall (Figure 8).
The patient’s weight is displayed on a 16-character dot matrix liquid crystal display. The weight data
may be viewed in either pounds or kilograms, with a displayed resolution of 0.1 for each.
INTENDED USE
The SR463iR Series is designed to be used as a stand-on scale for weighing ambulatory patients as
well as a Wheelchair / Chair / Walker scale for semi or non-ambulatory applications.
