Desiccant Air Dryer System
ACADAD5 & 15
Description:
The Desiccant Air Dryer (DAD) System provides an excellent alternative to Refrigerated Air Dryers. The DAD dryer is of the regenerative desiccant type that will provide for clean, dry air to -40 degrees Fahrenheit pressure dew points automatically. DAD systems are delivered complete with compressor pressure switch unloader/controller, oil removal filter, electronic drain valve, moisture indicator, desiccant, purge chamber(s), associated flow controls, and manual regeneration valve. DAD systems can be installed on most existing compressor installations, but must be sized according to maximum compressor air flow.
Maintenance:
DAD system should be installed within 5 feet of the air compressor package and interconnected between the compressor head(s) and storage tank, so that only clean, dry air enters the storage tank. A standard 115V wall plug is required. The ACADAD5 and ACADAD15 should be wall mounted with the supplied 3/8” lag bolts to wall studs spaced 16 inch on center.
Note: Choose a wall where sound from the dryer in not objectionable, as this system will produce a small amount of noise during operation.

Technical Service - (800) 233-4151
Compressor Package Preparation:
1.Disconnect electrical power to air compressor at main circuit breaker panel.
2.Open the drain valve located on the underside of the air storage tank to expel all moisture which may have accumulated. Close valve when completely purged.
3.Remove the existing compressor pressure switch and replace with the combination pressure switch/unloader provided with the DAD system.
Note: Prior to disconnecting the pressure switch wires, label or mark the individual wires so that the exact duplication of line and load connections is maintained when installing the new switch.
4.Remove compressor discharge line copper tubing connected between the discharge flex hose(s) and the entrance to the air storage tank.
5.On twin head compressors, install discharge flex “T” block.
6.Remove the air storage tank check valve located at the storage tank entrance. The DAD system is equipped with a storage tank check valve at the purge gauge assembly to facilitate manual purge operation.
Important: Failure to remove check valve may result in poor/abnormal performance.
Installing The DAD System (Refer to installation diagram on Page 1):
1.Install the 3/8” outlet copper tube connecting the DAD purge gauge/moisture indicator elbow compression fitting to the entrance of the air compressor storage tank.
2.Install the 3/8” inlet copper tube connecting compressor discharge flex hose with compression tube fitting at the entrance to the Ultair Filter on the DAD system.
Note: Use all copper tubing supplied to make loop. (See diagram on page 1).
3.Install the 1/4” copper tube from the elbow compression fitting at the outlet of the DAD Ultrair filter to the compression fitting of the compressor pressure switch unloader valve.
4.Check to ensure the bypass valves are in correct operating position.
5.Plug the 115V line cord into a 115V receptacle. Reconnect electrical power, and restart compressor.
6.Check that the DAD purge gauge and compressor storage tank gauge pressurize, and the compressor shuts off at 100 PSI, and automatically unloads the DAD system.
7.Check all tubing connections on the DAD and compressor package for any leaks with soapy-water solution.
Important: Seal all leaks.
