A-dec Service Guide, Vol. II A-dec Tubing
How to Identify
A-dec Tubing
There are four sizes of tubing used in A-dec products;
1/8", 1/4", 3/8", and 5/16".
A-dec 500 Tubing
The A-dec 500 product uses the new 5/16" tubing size for all
high flow air and water applications. Tubing functions are
identifiable by reading the tubing color and tracer markings.
Figure 3. Tracer patterns for identifying A-dec
tubing. (A) tracer pattern identifies the specific
tubing; (B) tubing color is the color of the
tubing material

Quick-Connect Fittings
Some tubing connections in the A-dec 500 equipment use quick-connect fittings.These fittings provide
fast, secure, push-on installation of tubing. These quick-connects also make removal of tubing during
servicing easy.
How to Use
Quick-Connect Fittings
Connect Tubing
1. Cut the tubing square, to ensure a secure connection.
2. Push the tubing into the connector until it can go no further.
3. Pull gently on the tubing to verify grip action.
Disconnect Tubing
Depressurize the unit. Push and hold the release
ring on the connector. Remove the tubing
from the connector.
Push and hold

Data Communication System A-dec Service Guide, Vol. II
Data Communication
System (DCS)
A-dec 500 equipment uses an electronic communication tool called the Data Communication System.
The DCS allows each module to communicate with each other, and automatically detects when new ones
are added. For example, when connecting a cuspidor to the system, the DCS will automatically recognize
the cuspidor module without having to program or change any settings.
Modules can be plugged into any of the data line connectors on the circuit board.The circuit board
recognizes which module has been plugged in and allows operation of that module to begin. Should a
module malfunction or fail to work, the DCS will maintain service to the rest of the modules. Other
modules will continue to function in spite of the one that has failed.
