IMPORTANT: READ PRIOR TO STARTING THIS EQUIPMENT
1.0 INSTALLATION
1.1 Location
A. For typical placement in a compressed air system, see
drawing.
B. Air compressor intake – Locate air compressor so that
contaminants potentially harmful to the dryer (e.g.
ammonia) are not drawn into the air system.
C. Clearances Free air flow
Front 36 inches (914 mm)
Back 6 inches (152 mm)
Sides 36 inches (914 mm)
Service - To facilitate maintenance leave 36 inches
(914 mm) of clearance in front of dryer.
D. Standard units are designed to operate in ambients:
Air-cooled: 45 to 110°F (7 to 43°C).
Water-cooled: 45 to 130°F (7 to 54°C).
E. Installations in altitudes above 4500 feet (1370 meters) –
Dryer is adjusted to operate in altitudes up to 4500 feet
(1370 meters). If dryer is installed in an altitude above
this, and has not been preset at the factory for this
altitude, contact manufacturer’s Service Department.
F. Theinstallationofaexibleconnectionpriortothe
dryer is recommended to prevent possible damage from
vibration.
NOTE: Outdoor installation – Standard units are designed
for indoor installation. Contact manufacturer if installing
outdoors.

1.3 Piping connections
A. Air Inlet - Connect compressed air line from air source
to air inlet. (Reference markings on dryer or see callout
drawing on page 14 for air inlet/outlet connection
locations.)
RefertoSerialNumberTagformaximum
workingpressure.Donotexceeddryer’sMaximumWorking
Pressure.
NOTE: Install dryer in air system at highest pressure possible
(e.g. before pressure reducing valves).
NOTE: Install dryer at coolest compressed air temperature
possible.Maximuminletcompressedairtemperature:120°F
(49°C).Ifinletairexceedsthistemperature,precooltheair
with an aftercooler.
B. Air Outlet – Connect air outlet to downstream air lines.
C. Bypass piping – If servicing the dryer without interrupting
the air supply is desired, piping should include inlet and
outlet valves and an air bypass valve.
D. Water cooled models – cooling water inlet and outlet
1. Connect cooling water supply to cooling water inlet.
2. Connect cooling water return line to cooling water
outlet connection.
NOTE: Strainer and water regulating valve are supplied on
water cooled models.
1.4 Electrical connections
IMPORTANT: Use copper supply wires only.
A. Dryer is designed to operate on the
voltage, phase, and frequency listed on
the serial number tag.
B. Connect power source to terminal strip in electrical
enclosure.
NOTE: Refrigeration condensing unit is designed to run
continuously and should NOT be wired to cycle on/off with
the air compressor.
NOTE: CHECK FOR CORRECT PHASING OF UNIT. After starting
the dryer, if an unusual noise is heard, or if the discharge
line does not get hot, the refrigeration compressor may be
running in the reverse direction. Immediately stop the dryer,
reverse two of the power leads, restart the dryer, and verify
the unusual noise is corrected and the refrigerant discharge
line is hot. FAILURE TO DO SO MAY DAMAGE THE COMPRESSOR
AND VOID THE WARRANTY.
1.5 Moisture separator
A. An automatic electric demand drain (EDD)
discharges condensate removed by the
separator. It may be desirable to pipe
the condensate from the EDD outlet to a
suitable drain.
B. Formanualdraining,convenientdryerdepressurization,
and EDD service, a three-way valve assembly has been
installed at the bottom of the moisture separator (and
cold coalescing filter where applicable). Review the
following for proper drain function:
• AutomaticDraining-Valvehandleshouldbe
positioned parallel to the valve body (as shown), with
the arrow on the handle pointing toward the EDD. In
this position, condensate will flow from the bowl to
the EDD.
• DrainIsolation(Shutdown)-Valvehandleshallbe
turned perpendicular to the valve body (rotate 90°). In
this position, condensate flow is shutoff.
• ManualDraining-Drainvalvehandleshallberotated
slightly past the drain isolation position to allow
throttling through the valve for manual discharge and
depressurization.
• NOTE: The quick disconnect fitting allows removal of
the entire drain assembly. However, the unit must
be depressurized prior to disassembly or serious
injury may occur.
NOTE: Discharge is at system pressure. Drain line should be
anchored.
NOTE: Condensate may contain oil. Comply with applicable
laws concerning proper disposal.
1.6 Operation
A. Verify that isolation valves are open. If the drain fails to
dischargeafterthevalveisenergized,theelectronic
controlcircuitwillrepeatedlyenergizethevalveinan
attempt to clear the discharge port. If, after 60 seconds,
the drain still fails to discharge, the control circuit then
switches to the alarm mode. In this mode the valve
isde-energizedandtheredalarmlightisactivatedon
the drain and the dryer controller. The valve is then
automaticallyenergizedevery4minutesfor5seconds.
Check the drain operation. Push drain (push-to-test)
button on the Energy Management Monitor control
boardtoenergizedrain.Aowofcondensateand/orair
should be present at the drain outlet. The alarm mode
automatically clears after the drain returns to normal
operation.
B. Condensate enters the reservoir (1) through the inlet
port. When the condensate level in the reservoir covers
the capacitance sensor, an electronic signal is sent to the
solid state countdown processor. The processor delays
the opening of the solenoid valve for a given period
of time. Once the time has elapsed, the solid state
processortransmitsinformationtoenergizethecoilin

b. Press ‘ESC’ at any time to return to the Main Menu.
NOTE: On dryers with air-cooled condensers, regular
condenser cleaning is recommended. Dirtiness
of ambient air at installation site will determine
frequency of service. Typically once a month is
recommended. Dryers contain an integral 3 micron
filter. As the filter element accumulates solid
contaminants, differential pressure increases. Solid
particulate load in the compressed air supply will
determine frequency of service. Typically element
changeout is recommended at least annually.

C. Starting dryer
IMPORTANT:Dryermustbeenergized24hoursbeforestart-
ing refrigeration compressor.
NOTE: It is recommended that dryer be started 15 minutes
before compressed air flow begins.
1. On water-cooled models: after 24 hours, begin cooling
water flow.
2. Check for proper electrical voltage.
3. Slowlypressurizeunitairsidebyopeninginletisolation

4. After 15 minutes, open outlet isolation valve slowly.
5. Close air bypass valve.
6. Dryer may be operated in Manual or scheduled modes.
NOTE: CHECK FOR CORRECT PHASING OF UNIT. After starting
the dryer, if an unusual noise is heard, or if the discharge
line does not get hot, the refrigeration compressor may be
running in the reverse direction. Immediately stop the dryer,
reverse two of the power leads, restart the dryer, and verify
the unusual noise is corrected and the refrigerant discharge
line is hot. FAILURE TO DO SO MAY DAMAGE THE COMPRESSOR
AND VOID THE WARRANTY.

3. Check interface panel.
NOTE: Interface panel will scroll through three screens
(Current Time/Operating Status, Hours to Service and Total
Operating Hours).
a. Verify that current time is correct.
b. Check HRS TO SERVICE: this indicates time remaining
until service is required; allow time for required
maintenance items to be ordered.
c. Check operating status:
MANUAL OVERRIDE - Dryer is either running
continuously (not being controlled by the scheduled
on/off times) or the refrigeration compressor has
been shut off using the ‘On/Off’ button.
SCHEDULE RUNNING - Refrigeration compressor
is being turned on and off by the monitor per-
programmed schedule (see B.3. to set schedule).
d. Check Temperature indicator - indicator should read
in the green area.
e. Check Alarm/Service light If illuminated, check
Interface panel.
1) If SERVICE DRYER appears, scheduled maintenance
time has elapsed (HRS TO SERVICE is 0). Perform
needed service and reset service interval (see B.3.).
2) If ALARM appears, a dryer fault is indicated; see
Troubleshooting Guide for possible remedies.
After fault correction push Reset button to turn
Fault alarm off.
Type of FAULTS:
LOW PRESSURE - the refrigeration compressor
control circuit has opened because of low suction
pressure.
HIGH PRESSURE - the refrigeration compressor
control circuit has opened because of high head
pressure. The high pressure switch must be reset
manually once the fault is corrected. Red reset
button is located on pressure switch inside unit.
HIGH TEMPERATURE - compressed air temperature
is above the set point.
