MINI INSTRUCTIONS
For complete instructions on installation, operation, and maintenance, consult manual.
I . INSTALLATION
1. Install on level surface.
2. Ambient temperature range: 35 to 120°F (1.7 to 49°C) [ if low ambient package supplied: -10 to 120°F (-23 to 49°C) ]
3. Install purge mufflers if shipped separately.
4. Connect air from compressor to inlet.
• Maximum compressed air temperature: 120°F (49°C)
• Maximum compressed air pressure: Refer to serial number tag.
• Minimum compressed air pressure: See section 2.2.1.2 .
5. Connect outlet to air system.
6. Refer to serial number tag for correct voltage. Make electrical connection to terminal strip in electrical enclosure. Standard units: connect
line to position 5, neutral to position 6 and ground to position 7.
Automatic purge saving system: connect wires to positions 2 and 3; ground to position 1.
7. Set controller for 120V or 240V using selector switch.
I I. START UP
1. Set or verify controller settings. See section 3.1.1.
2. SLOWLY pressurize unit.
3. Energize dryer by turning on/off switch on. ("I" is on; "O" is off)
4. Adjust purge air flow rate. Turn purge rate valve until Purge Pressure Gauge reads as shown in the following table.
NOTE: One tower must be purging when setting purge pressure.
III . OPERATIONAL CHECKPOINTS
1. Check that dryer is energized (indicating lights are illuminated)
2. MOISTURE INDICATOR - Indicator should be green (Allow 4 hours after start up for indicator to turn green).
3. TOWER PRESSURE GAUGES -
• Tower on line should read line pressure
• Tower off line should read 2 psig or less while purging. If pressure exceeds 2 psig replace purge muffler elements.
NOTE: An extra set of elements is shipped with dryer.
4. PURGE PRESSURE GAUGE - Verify proper setting.
5. CHECK FOR ALARM CONDITION.
IV . DEPRESSURIZATION
Isolate dryer. Run timer until both tower pressure gauges read 0 psig.
