GENERAL SAFETY
INFORMATION
1. Pressurized devices: This equipment is a pressure
containing device. Do not exceed maximum operating
pressure as shown on equipment serial number tag.
Make sure equipment is depressurized before working
on or disassembling it for service.
2. Electrical: This equipment requires electricity to operate.
Install equipment in compliance with national and local
electrical codes. Standard equipment is supplied with
NEMA 4, 4x electrical enclosures and is not intended for
installation in hazardous environments.
Disconnect power supply to equipment when performing
any electrical service work.
3. Breathing Air: Air treated by this equipment may not be
suitable for breathing without further purification. Refer
to OSHA standard 1910.134 for the requirements for
breathing quality air.
4. Noise: Do not operate dryer without mufflers installed.
5. High Velocity Air: Do not stand near mufflers during
tower depressurization.
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: 100 psig (6.9 barg)
5. Connect outlet to air system.
6. Refer to serial number tag for correct voltage. Make electrical
connection to terminal strip in control panel. Connect line to
position 5, neutral to position 6 and ground to position 7.
7. Verify voltage selector switch (115V or 230V). Position should
match voltage on Serial Number Tag.
II. 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.
MINI INSTRUCTIONS
For complete instructions on installation, operation and maintenance, consult manual.
III. OPERATIONAL CHECKPOINTS
1. Check that dryer is energized (indicating lights are illumi-
nated)
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 (0.14 barg)or less while
purging. If pressure exceeds 2 psig (0.14 barg) 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 (0 kgf/cm
2
)(test mode may be used to speed up cycle).
