CONTENTS
Self-contained Water System
Service information and warranty information
are located on the inside front cover and
front page.
The A-dec self-contained water system is
designed so you can optimize the quality of your
dental unit water. With an A-dec self-contained
water system, you control the quality of water
expelled from dental handpieces and syringes
in two ways: (1) you select the quality of your
dental unit water source, and (2) you perform
waterline asepsis and treat your waterlines with
the proper disinfectants.

Self-contained Water System
About Your Self-contained Water System
Caution
Use caution when using the self-contained water
system on any dental units equipped with
components which might fail when the water
supply is interrupted. Scalers and water heaters
(except the low voltage inline water heater/heated
syringe tubing) are examples of components which
can be permanently damaged if operated without a
continuous water source.
Note
The benefits from using your A-dec self-contained water
system are realized only when periodic system flushing and
disinfection procedures are followed. Failure to follow the
procedures in this manual may expose patients to
water with higher than normal microbe counts.
The disinfection procedures in this Owner’s Guide were
developed to enhance the water quality from an A-dec
handpiece delivery system. These procedures are
recommended for all A-dec handpiece delivery systems.
If you have questions regarding the A-dec self-contained
water system with non-A-dec equipment, contact
your equipment dealer or the manufacturer of your
delivery system.
Air, regulated to 40 psi (276 kPa), is supplied to
the water bottle through a restrictor barb attached
to the bottle cap. The air pressure in the bottle
forces the water from the bottle up into the water
pickup tube and out to the handpiece control
blocks and the syringes. Your dental unit water
system becomes a closed system, isolated from the
municipal supply.

The correct water for you to use in your A-dec selfcontained water system (for patient treatment)
depends on the quality of water available from your
municipal source and the goals you have for using an
A-dec self-contained water system.
Tap water: If you have confidence in the quality
of water delivered by your municipal supply, you
may consider using fresh tap water in your A-dec
self-contained water system. Use of tap water must
be done in conjunction with the operation and
maintenance procedures prescribed in this
manual. Failure to follow all procedures in this
manual can result in dental unit water that
contains higher than normal microbe counts.
Distilled water: If you have concerns about the
quality of water delivered through your municipal
supply, we recommend the use of water which has
been distilled under the standards of the United
States Pharmacopoeia (U.S.P.). Water distilled under
these standards has been processed in optimum
conditions. Most reputable bottled water
companies operate under U.S.P. standards.

Self-contained Water System
The Correct Water To Use
Throughout the remainder of this Owner’s
Guide, the water you have chosen to use will be
referred to as treatment water. It is important that
whenever treatment water is specified in this
manual for a procedure, you should be consistent
in using the same type of treatment water (fresh
tap water or distilled water).
5
Self-contained Water System
CAUTION
Do not use saline solutions, mouth rinses, or any
chemical solutions not specified in this manual in
your A-dec self-contained water system. These may
damage the water system components and cause the
failure of your dental unit. If you need to use such
solutions, a water supply system separate from your
dental unit should be used. As a general rule, water
that is suitable for drinking is suitable to run through
your delivery system. (See “Disinfectant Solution” on
page 8 )
1. Use only A-dec water bottles.
2. Never use PET
®
material soda pop-type bottles.
3. Never use two liter bottles.
The water bottle should be mounted where
visible so you and your staff can easily monitor the
level of water in the bottle.

Self-contained Water System
About The Water Bottle
WARNING
NEVER USE GLASS BOTTLES ON THE A-DEC SELFCONTAINED WATER SYSTEM. GLASS BOTTLES CAN
POSE A SERIOUS SAFETY HAZARD IF BROKEN
WHILE PRESSURIZED.
WARNING
NEVER INSTALL A DAMAGED BOTTLE.
To use the A-dec self-contained water system, fill
the bottle with treatment water. If the dental unit is
not ON, move the master on/off toggle to the ON
position.
Align the full bottle with the self-contained water
cap, making sure the 1/4-inch (6.4 mm) clear
pick-up tube extends straight down into the water
bottle. Screw the bottle onto the cap until it is
secure. Air can be heard filling the bottle until the
bottle is pressurized to 40 psi (276 kPa), which may
take up to 60 seconds. Operate the syringe and
handpieces to clear any air from the water system.
To prevent running out of water during midprocedure, we recommend that you refill the bottle
with treatment water before running too low.
Replace a near-empty bottle by unscrewing it from
the cap (slowly, to release the air pressure) and
replace it with a filled bottle. There is no need to
move the dental unit master on/off toggle to the
OFF position while changing bottles.

Self-contained Water System
WARNING
Before handling, filling, and installing water bottles
on the A-dec self-contained water system, take special
care to wash hands with anti-microbial soap. Then
wear a new pair of exam gloves. Avoid touching the
water pickup tube (see Figure 1, page 3).
Activating The System
There are three major elements of asepsis for
A-dec self-contained water systems:
1. Bottle disinfection.
2. Daily purging with air.
3. Weekly water system purging and disinfection.
We recommend a disinfectant solution of
one part household bleach (5.25% sodium
hypochlorite) plus nine parts treatment water.
This 1:10 (one-in-ten) solution should be used in
all bottle and waterline asepsis.
For the following procedures, fill a treatment
bottle with approximately 600 ml (about 20 oz) of
the 1:10 disinfectant solution. Simply mix 60 ml
(about 2 oz) bleach with 540 ml (about 18 oz)
treatment water. Make certain to prepare fresh
solution for each clinic week.
8
Self-contained Water System
Disinfectant Solution
Caution
When using a chemical such as sodium hypochlorite
which can stain or bleach tile, carpeting, or upholstery;
take the necessary precautions to prevent spills and
dripping. While flushing the system, hold the syringe
and handpiece tubings over a sink, basin or bucket.
Suggested Asepsis For A-dec
Self-contained Water Systems
To disinfect an A-dec water bottle pour about half
a cup of the 1:10 solution into the bottle, cap and
shake for about five seconds, then allow it to stand
for 10 minutes. Shake the bottle again. Empty the
bottle and rinse twice with treatment water.
Your dental unit should be purged with air at the
end of each clinic day. Make sure the handpieces
have been removed from the tubings before
purging the system.
1. Remove and empty the installed water bottle,
then reinstall it.
2. Hold handpiece tubing and syringe over a
basin or bucket. Turn the unit on, wait a few
moments, then operate the unit flush valve,
syringe, and foot control until the water is
purged from the system.
3. Turn off the unit.
9
Self-contained Water System
Bottle Disinfection
Caution
Plastic water bottles cannot withstand heat
sterilization. Attempting to do so will destroy the
bottle and may damage your sterilizer. The A-dec selfcontained water system was not designed to deliver
sterile water from handpieces and syringes.
Daily Procedures (Purging the Dental Unit)
The following procedures should be performed at
least once a week, preferably at the beginning of
each clinic week, before the first patient.
1. Make sure the handpieces have been
removed from the tubings before purging
the system.
2. Make certain the unit has been purged with
air (see Daily Procedures on page 9).
3. Fill and flush with disinfectant:
a) Make sure the unit is off. Remove the empty
water bottle and set it aside for disinfection
(see Bottle Disinfection on page 9).
b) Add approximately 600 ml (about 20 oz) of
the 1:10 disinfectant solution (refer to
Disinfectant Solution on page 8) to a
disinfected bottle. This will be referred to as
the disinfectant bottle. Install the bottle.
c) Hold handpiece tubings and syringe over a
basin or bucket. Turn the unit on, wait a
few moments, then operate the unit flush
valve, syringe and foot control until a
steady stream of disinfectant solution
begins flowing through the tubings
(about 15–20 seconds).
4. Allow disinfectant to remain in the unit
for at least 10 minutes (never more than
30 minutes).

Weekly Procedures
5. Purge the unit with air:
a) Install an empty disinfectant bottle to the
unit. Hold the handpiece tubings and
syringe over a basin or bucket. Turn the
unit on, wait a few moments, then operate
the unit flush valve, syringe, and foot
control until the disinfectant solution is
purged from the system.
b) Turn off the unit.
6. Fill with treatment water:
a) Make sure the unit is off. Remove the empty
disinfectant bottle. Then install a disinfected
bottle filled with treatment water.
b) Hold handpiece tubings and syringe over a
basin or bucket. Turn the unit on, wait a few
moments, then operate the unit flush valve,
syringe, and foot control until a steady
stream of treatment water begins flowing
through the tubings (about 20–30 seconds).
Your dental unit is now ready for use.
In some applications, dental units may have long
periods of downtime between use. For units that
will not be operated for longer than one week, we
recommend the above flushing and disinfecting
procedure immediately before and after each
lengthy downtime period. Follow Weekly
Procedures 1–5 (see page 10).
For surface cleaning and disinfecting instructions,
refer to your Equipment Asepsis Owner’s Guide,
