Your Decade 1021 Vac Back chair is available in
two configurations:
1. As part of an integrated delivery system that is
connected into the regulated air and water
supplies of an existing delivery system; or
2. As a free-standing delivery system that does
not require air and water connections to an
existing delivery system.
The Vac Back comes equipped with the following
instrumentation: autoclavable saliva ejector,
autoclavable high volume evacuator (HVE), auto-
clavable syringe, and solids collector.
The Master On/Off toggle turns the water to the
Vac Back chair ON or OFF. When the system is left
unattended or is no longer in use, the Master
On/Off Toggle should remain in the OFF position.

When the Master On/Off toggle is in the ON
position, the On/Off Indicator will be red, indicating
that the unit is pressurized. (This is not a lamp; the
indicator is operated by air pressure.)
The Master On/Off toggle and On/Off Indicator
are located on the top of the floor box (See Figure 1)
for free standing configurations only. For other
configurations, the Master On/Off toggle can be
found on the delivery system.
Autoclavable Syringe. The syringe on your Vac
Back Chair is A-dec’s autoclavable air and water
syringe (see Figure 2).
Autoclavable Saliva Ejector. The saliva ejector is
equipped with an on/off control valve (see Figure 2).
Autoclavable HVE. Your 1021 Vac Back comes
with one (standard) or two (optional) autoclavable
HVE(s) (see Figure 2).

Solids Collector. The solids collector, located
on the chair back, collects solids and prevents
them from entering the central vacuum system
(see Figure 3).
For operating instructions, refer to your Assistant’s
Instrumentation Owner's Guide ( A-dec Publication
No. 85-2610-00).
Your A-dec autoclavable syringe and vacuum
instruments were designed for easy cleaning and
infection control.
For vacuum instrument and syringe asepsis, refer
to your Assistant’s Instrumentation Owner’s Guide
(A-dec Publication No. 85-2610-00) and your
Autoclavable Syringe Owner’s Guide (A-dec
Publication No. 85-0680-00)
For further asepsis instructions, refer to your
Equipment Asepsis Owner’s Guide (A-dec Publication
No. 85-0696-00).

For system air and water adjustments, refer to
your Floor Boxes Owner’s Guide (A-dec Publication
No. 85-2611-00).
If the instrument holder arm on your chair starts to
droop when all the instruments are in place, or if the
arm swings too freely, an adjustment is necessary.
To adjust the horizontal angle of the arm, lift
the arm up and evenly tighten the break-away
mechanism screws (see Figure 4) with a 5⁄32-inch
hex key. Adjust arm to the desired position.
To adjust the tension at the joints of the arm
(see Figure 4), use a 3⁄32-inch hex key and turn the
adjustment screws clockwise to increase the tension,
counterclockwise to reduce the tension.

Syringe air and water flow are controlled by
two pinch valves in the chair back (see Figure 5).
Remove the four chair back cover screws, then
remove the cover to access the pinch valves
(see Figure 4 on page 5).
Move the Master On/Off toggle to the ON
position and make sure there is air and water
pressure to the syringe. To adjust the water flow,
press the left syringe button and turn the water
pinch valve clockwise to decrease flow or
counterclockwise to increase flow. A strong
water flow is recommended.
Push both syringe buttons (the spray position)
and adjust the air flow pinch valve to achieve the
desired spray.

Given proper care, your Vac Back chair will
provide years of reliable service. In the event
that something does go wrong with the unit,
this troubleshooting guide will tell you what
to do before calling to have it serviced.
This guide is not intended to isolate every problem
that could arise. Rather it is designed so you can
quickly identify the problems that can be repaired
without special training or equipment.
If the following procedures do not identify and
correct the problem, then you should call your
authorized A-dec dealer. Any time you call your
dealer, be prepared to provide them with this
information:
1. Model number*
2. Serial number*
3. Symptoms of the problem
4. What action you have taken toward
correcting the problem
*The Vac Back chair model and serial number tag is
located under the seat/toeboard, beside the spring. In all
cases, the first four digits on the tag are the model number,
the rest of the digits are the serial number.
