INTRODUCTION
Thank you for purchasing our Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale. The 7550
wall-mount wheelchair scale features a unique fold-up storage design that saves space when
not in use. The 7550 easily accommodates most wheelchairs with its spacious 36 in W x 33 in
D / 91 cm W x 84 cm D platform, and yet requires very little floor space when folded up. The
slim 7.3 in / 18.5 cm profile takes up minimal space when installed in a medical facility hallway,
clinical office, or patient room. When you’re ready to weigh, simply lower the platform and the
gas spring lifting mechanism will gently lower it into place. The patient may be easily rolled
onto the scale in a wheelchair, weighed in a chair, or while standing. The scale features a high
1,000 lb x 0.2 lb / 450 kg x 0.1 kg capacity for bariatric weighing, two-way ramps, and built-in
Wi-Fi and Bluetooth 5.0 for EMR/EHR.
This manual is provided to guide you through the setup and operation of your scale. Please
read it thoroughly before attempting to set up or operate your scale and keep it available for
future reference.
This manual is for the following models of the 7550 Wall-Mount Fold-Up Wheelchair Scales:
7550, 7550-AC, and 7550KGEU

StableSENSE® can be used with clinical scales to lessen the effects of the patient’s
movement or vibration on the scale. Any application affected by vibration or movement on
the scale platform can benefit from using StableSENSE®.

SITE PREPARATION REQUIREMENTS
The Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale is a precision weight indicating
instrument. As with any precision instrument, it requires an acceptable environment to operate
at peak performance and reliability. This section will assist you in obtaining such an
environment.
Environmental
For indoor use only.
Suitable for dry environments only RH < 90% and non-condensing environments.
NEVER allow the scale to get wet.
The scale meets or exceeds all certification requirements within a temperature range
of 14 to 104 °F (-10 to +40 °C).
The scale should be placed out of direct sunlight and to provide adequate air circulation, keep
the area around the scale clear.
Do not place the scale directly in front of a heating or cooling vent. Such a location will subject
it to sudden temperature changes, which may result in unstable weight readings.
When using the AC power adapter, ensure that the scale has good, clean AC power and is
properly grounded. In areas subject to lightning strikes, additional protection to minimize
lightning damage, such as surge suppressors, should be installed.
Electrical Power
The Detecto 7550 Wall-Mount Fold-Up Wheelchair Scale has been designed to operate from a
100V to 240V AC 50/60Hz 12V DC 1A wall plug-in UL/CSA listed AC power adapter (Cardinal
part number 6800-1045). NOTE: On installations using 220V to 240V AC, use the optional 100
to 240V AC 12V DC 1A Multi-Pin Input AC power adapter (Cardinal part number 6800-1047).
The socket-outlet supplying power to the indicator should be on a separate circuit from
the distribution panel and dedicated to the exclusive use of the indicator.
The socket-outlet shall be installed near the equipment and shall be easily accessible.
Electrical Noise Interference
To prevent electrical noise interference, make certain all air conditioning and heating
equipment, lighting, or other equipment with heavily inductive loads, are on circuits separate
from the system. These sources of disturbances can affect the operation of the scale. Steps
must be taken to prevent possible adverse effects on the scale. For example, using simple line
filters, isolation transformers, power regulators, or uninterruptible power supplies.

UNPACKING
IMPORTANT: UNPACKING AND INSTALLATION OF THIS PRODUCT
SHOULD BE PERFORMED BY TWO PEOPLE. PLEASE READ THROUGH THE
INSTRUCTIONS CAREFULLY BEFORE STARTING TO INSTALL THE SCALE.
NOTE: Make certain the scale has been received in good condition. Check for any damage
incurred in shipping. If the scale has been damaged, place a claim with the carrier. It is the
responsibility of the purchaser to file all claims for any damages or losses incurred during
transit. Keep the carton and packing material for return shipment if it should become
necessary.
1. Cut the shipping straps and remove the shipping carton top to unpack the scale.
2. Remove all cardboard inserts from around
the scale, and then cut the tape securing
the flaps on one end of the carton.
3. Turn back the packing material, exposing
the scale. With an assistant, lift the scale
high enough in the shipping carton to
remove the box containing the shims,
owner’s manual, and other documents, and
the Wall Mount from under the scale. Lower
the scale back down into the carton.
4. With an assistant, slide the scale out of the
carton and raise it to an upright position.
NOTE: DO NOT lift the scale by the
strap securing the weighing platform
to the scale frame to raise the scale
to the upright position.
CAUTION! DO NOT remove the
strap securing the weighing platform
to the scale frame until instructed to
remove.
Leave this strap on until
instructed to remove!
DO NOT lift the scale by
this strap!

INSTALLATION
Choose the Scale 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.
NOTE: The front load cells of the weighing platform will be off the floor.
The rear 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
rear load cells will not touch the floor when the
weighing platform is lowered. If the wall mount
is too high, it 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.
