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 floor.
1.3 Piping connections
A. Air Inlet - Connect compressed air line from air source to
air inlet. (Reference markings on dryer 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:
130°F (54°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. If dryer is supplied with a cord and plug, install in a
receptacle of proper voltage.
C. Electrical entry on larger dryers is through a hole in the
cabinet. It is located on the right side panel when facing
the front of the unit. Connect power source to terminal
strip in electrical enclosure as shown on the wiring
diagram included with the dryer.
NOTE: The dryer should NOT be wired to cycle on/off with
the air compressor.
1.5 Moisture separator
A. Models 90-140:
Separator (and Oil Removal Filter where
applicable) has an internal drain which
automatically discharges condensate.
Models 190-675:
Separator (and Oil Removal Filter where applicable) has
an electronic demand drain (EDD) which automatically
discharges condensate.
NOTE: It may be desirable to pipe the condensate from
the Automatic Drain outlet to a suitable drain.
B. Models 90-140:
Separator has a knurled fitting with flexible drain
tubing attached. Be sure knurled fitting is tightened
by turning counter-clockwise before operating dryer.

TURN COUNTERCLOCKWISE
C. Models 190-675
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 EDD 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. The valve is then automatically energized every 4
minutes for 5 seconds. Check the drain operation. Push
drain (push-to-test) button on the drain or the Electronic
Controller (if equipped) to energize drain. A flow of
condensate and/or air should be present at the drain
outlet. The alarm mode automatically clears after the
drain returns to normal operation.
