INSTALLING DESICCANT CARTRIDGES & MUFFLERS

After base assembly is mounted, install desiccant cartridges to base assembly as follows:

1. Install o-ring into groove of each center thread adaptor in base assembly.

2. Lubricate both o-rings and threads.

3. Lubricate contact surface of flat gasket located in cartridge plate.

4. Start cartridge onto thread adaptor, being careful not to cross thread. Turn cartridge

clockwise until flat gasket contacts casting surface. After gasket contact turn

cartridge only ½ additional turn.

NOTE: Do not over-tighten cartridge or future removal will be difficult.

5. Apply ant-seize compound to muffler threads & install a muffler into each exhaust

port of the DA Series.

MICRO LOGIC TIMER (MLT) ELECTRICAL CONNECTION

1. Plug-in MLT power cord to 110-120 Volt AC grounded receptacle.

NOTE: The MLT device is polarity sensitive. MLT will not operate if power (+) and

neutral (-) leads are switched.

START-UP/CHECK

1. Ensure that all air lines fittings are properly connected.

2. Pressurize system.

3. Check air line fittings for leaks and repair leaks.

4. Observe operation of the DA Series for proper function as described in the DA

Series OPERATION/CYCLE section

DA Series OPERATION/CYCLE

1. The Micro Logic Timer (MLT) controls drying and regeneration cycles of the DA

Series by energizing and de-energizing the “air control valve” of the DA Series at

120-second intervals. An indicator light on MLT will be on during energized cycle

and off during the de-energized cycle.

2. The DA Series “air control valve” controls air-flow direction through the DA Series.

During operation one desiccant cartridge is drying air and other cartridge is being

regenerated.

3. During operation there will be a light flow of air from ONE exhaust port of each DA

Series unit. This is normal, regeneration , air flow and the air flow will alternate

(every 120 seconds) from one exhaust port to the other in conjunction with the MLT

cycles. When the DA Series cycle alternates there will be a momentary burst of air

from one of the exhaust ports. This is normal and is beginning of regeneration

process.
