mercury and damaged ADC DIAGNOSTIX ™ instrument. Please call our customer service
department toll free at 1-800-ADC-2670. They will send you out a complete mercury return
kit p/n 985 along with detailed instructions on the proper packing and return of the dam-
aged instrument and collected mercury.
How do I return a broken unit?
Regardless of whether or not the unit is intact (no mercury leakage) it may be
returned to ADC for service via UPS only (USPS does not authorize shipment of mer-
cury). When returning an intact mercurial unit, be sure to include a note listing your
name, address, daytime phone number, and symptoms of the unit. When packing mer-
curial units for transport, be sure to follow the instructions in the “Packing and Shipping”
section below.

If the unit is damaged and mercury has leaked, please call our customer service
department at 1-800-ADC-2670. We will be happy to send you a complete mercury
return kit, part number 985 with instructions on the safe transportation of the
product. Please note that the mercury return kit is NOT necessary but is provided as
a convenience. If you choose not to use an ADC return kit, you will need a leak-
proof, sealable 3 mil plastic bag (for each unit), rubber bands/twist ties/fasteners, a
200 test corrugated carton, and the appropriate shipping labels. Only the manometer
itself and not the inflation system (cuff, connectors, bulb and valve), wall brackets, or
mobile base (depending upon the unit) need be returned. Please be sure to follow
the instructions for shipment in the “Packing and Shipping Instructions” section
below.
Note: We can only accept the return of ADC ’s DIAGNOSTIX™ mercurial instruments
for repair services.
PACKING AND SHIPPING INSTRUCTIONS
Important Note: Failure to follow the proper packing and shipping instructions below
for mercurial return kits could result in mercury leakage during transit. The shipper will
be responsible for all costs associated with cleaning mercurial spills that were caused
by improper packaging and shipping methods.
You will be sealing each mercury unit in TWO polybags with bubble wrap in
between. Only pack a MAXIMUM of 3 units per return. (Assorted styles are accept-
able) It is very important to note that the Department of Transportation (HAZMAT)
requirements will require special caution labels for any boxes that contain 1 pound
or more of mercury. Three mercurial units are below this 1 pound requirement, and
do not require any additional labeling.
1. Remove the inflation system, basket(s), rod, and base from all mercurial
units before packing and dispose of in accordance with local regulations.
ADC will ONLY accept the main mercurial units for return.
2. Put ONE mercurial unit in a polybag and seal it with a twist tie or
rubber band closure.
3. Wrap bubble wrap around the mercurial unit and secure with adhesive
tape. This will help prevent the port connector from puncturing the
second polybag.
4. Enclose the wrapped mercurial unit in another polybag. Seal the polybag

mercury into the tube with the help of a small paper cone or funnel. The instrument
is then tipped in the direction of the reservoir and returned to a vertical position
before the new mercury level is observed. Repeat the process as necessary to bring
the mercury up to the “0” calibration mark.
HOW TO CLEAN OR REPLACE MERCURY
When removing the mercury from an instrument we strongly suggest you wear
disposable rubber gloves and goggles. Be sure to remove all jewelry. Also, an inex-
pensive plastic storage box makes an excellent portable work station. Unscrew the
knurled cap at the top of the graduated plastic tube. Then carefully pour all the mercury
into a paper cup or glass container and tap reservoir in order to get all the mercury
out of the reservoir.
Roll a small cone of ordinary copy paper, leaving a small opening at the end of the
cone, and pour the mercury through this cone into another clean paper cup or glass
container. Repeat a few times. Residue will adhere to paper.
Remove the graduated plastic cartridge tube and clean it. The bore of the tube may be
easily cleaned with alcohol and a lint free pipe brush. The outside of the tube should also
be cleaned occasionally by wiping with a damp cloth.
Replace the graduated plastic tube and return the clean mercury to the instrument
through the opening at the top of the tube, using the paper cone described above.
Check the mercury level - it should be at the “0” line on the plastic tube with the
inflation system disconnected and the instrument in its correct position (vertical for
desk or wall mount models, 15° incline for mobile instruments). If some mercury has
been lost, add enough (through the top of the plastic tube) to bring the rim of the
mercury meniscus to the “0” calibration mark. Then replace the knurled cap at the top
of the graduated plastic tube, and screw it down firmly.
REMOVING THE GRADUATED PLASTIC TUBE
ADC’s EZ-Tube ™ system facilitates removal of the 5mm graduated plastic cartridge
tube. To remove, follow these steps:
1. Force mercury out of the cartridge tube by tilting instrument TOWARDS reservoir
(to the right on 922, to the back on 932, 952, or 972).
Note: The 952 must first be removed from its swivel wall bracket.
2. Secure the mercury within the reservoir by moving the lock switch to the “Off”
position.
Note: Make sure all mercury is out of the cartridge tube.
3. Lift on the spring loaded EZ-Tube ™ mechanism located at the top of the
instrument (932, 952, 972). Tilt instrument forward to free tube. If necessary use a
small flathead screwdriver to help dislodge the top of the tube. On 922, remove
knurled top cap by turning counterclockwise. Remove tube, by sliding upward
until fully dislodged.
4. To replace tube, lift EZ-Tube ™ mechanism and insert base of tube into main
unit, being sure graduation marks face out. Next, position top of tube and
release EZ-Tube
™ mechanism. On 922 replace by sliding down through top cap
opening and position. Secure top cap by turning clockwise until tight. Be sure to
tighten thoroughly.
5. Unlock reservoir and tilt instrument AWAY from reservoir forcing mercury back
into tube.
6. Check for “0” point.
