SAFETY INFORMATION

DO NOT REMOVE CAP ON FILL PORT UNTIL ALL PRESSURE IS OUT OF DRYER.

DO NOT REMOVE OR ADJUST ANY EQUIPMENT ON DRYER UNTIL ALL PRESSURE IS OUT OF THE

DRYER.

DO NOT OPERATE DRYER ABOVE MAXIMUM WORKING PRESSURE.

DO NO ALTER VESSEL IN ANY WAY, SUCH AS WELDING OR GRINDING.

LOCATION

For maximum performance, always locate dryer where the inlet compressed air temperature is lowest. Inlet air

temperature to dryer must be no more than 10°F above the lowest temperature in the air system. Outlet dew point

(level of dryness) from dryer depends on inlet temperature of the compressed air.

If temperature of air from the compressor is not within this 10°F range, an aftercooler is required to reduce the air

temperature before it is processed through the dryer. An air-cooled aftercooler sized for a 10°F approach is

recommended for installation before the dryer. The aftercooler compensates for changing atmospheric

temperatures by exchanging heat between the atmospheric and compressed air so that inlet compressed air

temperature to the dryer is within the 10°F range. A separator is then required on the aftercooler outlet to remove

the condensed water.

Where air lines or equipment are located outdoors, install dryer outdoors in coolest location.

In systems where air usage fluctuates or there are sudden demands, protect dryer against air flow surges.

For best efficiency, locate dryer where air pressure is highest in system; more air can be dried at higher pressures.

INSTALLATION

1. Install dryer in an upright (vertical) position on a level surface with fill port on top. On wall-mounted models

DD-12 thru DD-48, provide strapping or additional support to prevent stress on piping to dryer.

2. Install by-pass piping with inlet, outlet and by-pass valves to isolate dryer for adding desiccant.

3. Connect inlet air piping to dryer inlet (lower connection) and outlet piping to dryer outlet (top connection).

Compressed air must flow through dryer from bottom to top of vessel or air will not be sufficiently dried.

WARNING: ALWAYS INSTALL PARTICULATE FILTER AFTER DRYER TO PREVENT ANY ACCIDENTAL

FLOW OF MATERIALS FROM DRYER INTO DOWNSTREAM EQUIPMENT.

4. Connect drain line to coupling on bottom of dryer vessel, and install manual valve at end of line. Note: Install

motorized drain (optional equipment) as indicated on instructions supplied with automatic drain.

5. Install pressure relief valve to conform to OSHA Standard 1910.169; also check local codes.

6. Remove cap from fill port on top of dryer and pour in recommended amount of Deli-Dry desiccant (see chart

below). Check to make sure that vessel is filled to within 1 or 2" of dryer top.

7. Replace cap on fill port, and tighten securely.

8. Close inlet and outlet shutoff valves; also close drain valve.

9. Start compressor: then slowly open dryer inlet valve to pressurize dryer gradually.

10. Open outlet valve slowly; close by-pass valve.

CAUTION!!!!!

MAKE SURE THAT DRYER IS NOT SUBJECTED TO AIR SURGES WHILE IT IS BEING PRESSURIZED.

OPERATION

START-UP: Slowly open outlet shutoff valve and then inlet valve. Close by-pass valve.

SHUT-DOWN: Maintain pressure in dryer during shut-down by following this procedure before shutting off air

supply to dryer: Open by-pass valve. Then close dryer inlet and outlet shufoff valves.

MAINTENANCE

*Drain dryer after every 8 hours of operation.

Open manual drain valve and allow all collected drain solution to discharge from dryer. On dryers equipped with an

automatic drain, check periodically by pushing test button to make sure that drain is operating properly.

WARNING

Always drain dryer regularly. If drain solution reaches an abnormally high level, air flow may force

solution into system piping and cause damage to downstream equipment.

*Inspect tablet level through sight window regularly. Add DELI-DRY TABLETS when top of bed is level with

sight window. Use the following procedure:

1. Isolate dryer from air system by closing inlet and outlet valves; open by-pass valve.

2. Open drain valve; depressurize dryer completely.

3. After all pressure is out of dryer, unscrew cap on fill port.

4. Add enough tablets so that vessel is filled.

5. Replace cap on fill port and tighten securely.

6. Slowly open outlet valve and allow air to bleed through drain valve.

7. Close drain valve, and open inlet valve slowly to pressurize dryer graduallly.

8. Close by-pass valve.
