1.2 Mounting
Mount the dryer on a level solid surface. Holes are provided in
thedryerbasetopermanentlymountthedryertotheoor.
1.3 Piping Connections
A. Air Inlet - Connect compressed air line from air source to
air inlet.
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. Also, it is recommended to add water
inlet/outlet temperature and pressure gauges to the water
piping.
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. Electrical entry is through a hole in the
top of the cabinet. Route wires through the bottom of the
electrical enclosure. Connect power source to the terminal
strip in the electrical enclosure as shown on the electrical
schematic included with the dryer.
NOTE: Refrigeration condensing unit is designed to run
continuously and should NOT be wired to cycle on/off with the
air compressor.
1.5 Electronic Demand Drain
A. An automatic electric demand drain (EDD)
discharges condensate removed by the
separator.
B. All dryer models are supplied with one
EDD. Models with the additional (optional)
oilremovallteraresuppliedwithasecond
EDD.
C. Thedrainsarepipedtottingsinthelegoftheunit.
Condensateshouldbepipedfromthisttingtoanopen
ventedoordrainorsump.
NOTE:Discharge is at system pressure. Drain line should be
anchored.
NOTE:Condensate may contain oil. Comply with applicable
laws concerning proper disposal.
D. Verify that isolation valves are open. If the drain fails to
discharge after the valve is energized, the electronic con-
trol 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 Manage-
ment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.
E. Description of Operation: Condensate enters the
reservoir (1) through the inlet port. When the conden-
sate 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 sole-
noid valve for a given period of time. Once the time has
elapsed, the solid state processor transmits information to
energize the coil in the solenoid valve (2). The magnetic
force of the coil causes the solenoid core (3) to move,
closing the pilot air supply line and opening the pilot air
exhaust line. After the pilot air above the diaphragm (4) is
vented, pressure in the reservoir opens the discharge port
and forces the condensate through the discharge port and
outlet piping.

2.3 Filter Monitor (optional)
The Filter Monitor continuously monitors the differential pres-
sure (pressure drop) across the standard grade 9 element in
the moisture separator. Models with the optional grade 5 Oil
Removal Filters include a dedicated Filter monitor as well to
alert the operator of the need for element replacement when
any of three operating criteria are met:
1. Maximum elapsed time (service interval) before change-
out - operator alerted when user selected time period
elapses.
2. Maximum allowable differential pressure - operator
alerted when user selected maximum differential
pressure occurs.
3. Intelligence - operator alerted when the optimum time
to replace the element(s) has occurred. The Monitor
calculates this using the element type, the initial
characteristic pressure drop and historical pressure drop
data.

Initialize
Use Initialize on initial start-up or after
replacing elements. See section 2.3
for programming instructions.
If Initialize is selected the program
willignoretherst24hoursofoperationtoallowthe
element(s) to achieve a steady state. After this period,
pressure drop measurements will be averaged over the
next 144 hours to determine an initial characteristic pres-
sure drop. The differential pressure calculation used to
determine the optimum time for element replacement uses
this characteristic drop as the starting point.
After the initialization period, Monitor automatically
switches to the Run mode.
Run
To select Run, press Scroll button so that only
the run icon is displayed. If RUN is selected,
the monitor uses the previous initial charac-
teristic pressure drop as the reference. Use
this mode if the Monitor is re-programmed but the element
is not replaced.

3.0 MAINTENANCE
3.1 Monthly
A. Air-Cooled:Cleanrefrigerantcondenser.Blowthens
of the condenser clean with compressed air, if necessary,
remove heavier soiling with a suitable cleansing agent.
B. Water-cooled - clean strainer monthly, more often if
required. Shut off water, remove small plug to relieve pres-
sure, then remove large plug to remove strainer. Clean
strainer and replace.
C. Check the condensate drains by pressing the Drain Test
button on the control panel (see page 5 for description and
location). Visually check to assess whether condensate is
separated and discharged.
D. Check the dew point temperature on the control panel.
E. Check the inlet compressed air temperature and the ambi-
ent temperature (or inlet cooling water temperature) to
assure they are within the operational limits.
Ref: 3.2, C, 2, e through h
3.2 Annual Maintenance
A. Check all terminals in the switchgear cabinet and tighten
them up if necessary.
Check to be sure the unit is de-energized.
B. Maintenance/Cleaning of the condensate drain.

Check to be sure the unit is depressurized
and de-energized.
Maintenance recommendation:
1. Remove two pan head screws [1] and lift off conden-
sate drain. The elbow adapter stays in place.
2. Disconnect discharge hose [2].
3. Turn the 6 pan head screws [3] until heads are level
with the outer edge and take off diaphragm seat [4].
4. Replace wearing parts. (All necessary service parts
can be ordered in a service kit – See Parts List.)
5. Reassemble condensate drain unit in reverse order.
C. Replacetheltercartridgesinthelter.(Allnecessary
service parts can be ordered in a service kit – See Parts
List.)

SIZING
Determining dryer capacity at actual operating conditions.
Todeterminethemaximuminletowcapacityofadryeratvari-
ous operating conditions, multiply the rated capacity from Table
1 by the multipliers shown in Table 2.
Example: How many scfm can a 60 Hz air-cooled model 1000
handle when compressed air to be dried is at 200 psig and
100°F; ambient air temperature is 80°F?
Answer: 1,000 x 1.22 x 1.12 = 1,366 scfm.
TABLE 1
Rated capacity (scfm) @ 100 psig inlet pressure, 100°F inlet
temperature, and 100°F ambient temperature.

 Whenremovingliquidsatratedowconditions,the
pressure drop will be 5 psi (0.35 bar), or less, across
the entire dryer. An increase in pressure drop will
occuronlyastheseparator/lterelementsbecome
loaded with solid particles. It is recommended, for
maximumltrationefciency,theseparator/lterele-
ments be replaced when the pressure drop across the
dryer exceeds 10 psi (0.7 bar), or every 12 months,
whicheveroccursrst.
2. Replacement of the Separator/Filters
Depressurize the unit before servicing.
Failure to do this may result in injury.
a. Open the bypass between compressed air inlet and
outlet. (if equipped)
b. Close the shut-off devices at the compressed air
inlet and outlet.
c. Press the Drain Test button on the control panel
(see page 5 for description and location) until the
system is depressurized.
d. Switch off the dryer.
e. Remove the insulation [1].
f. Loosenthescrews[2]ofthelterhousing.Caution
is necessary as the system may still be under slight
residual pressure.
g. Removeallscrewsexceptoneandswingange[3]
to the side.
h. Pull out the old cartridges [4].
i. Push new cartridges on to the mounting posts in the
bottom of the separator vessel.
NOTE: Do not touch the foam sleeves of the
cartridgeswithyourngers.
j. Close housing in reverse order.
k. Put on insulation.
l. Switch on the dryer.
m. Repressurize the dryer by slowly opening the
compressed air inlet valve.
n. Slowly open the compressed air outlet valve.
o. Slowly close the compressed air bypass valve (if
equipped).
3.3 Filter Monitor Programming (optional)
A. Each Filter Monitor needs to be initialized whenever a new
lterelementisinstalled.InitializationresetstheIntel-
ligence circuitry to begin establishing a new performance
baseline consistent with the unique signature of each
individual element.
B. To retain the existing settings previously established
simply:
1. Press and hold the “enter” button until the
programmingiconbeginsashing.
2. Slowlypressandreleasethe“enter”buttonve(5)
times.
3. Only the will appear on the LCD display for
therst2minutesofoperation.Initializationisnow
