RECEIVING, MOVING, AND UNPACKING
A. RECEIVING
This shipment has been thoroughly checked, packed and
inspectedbeforeleavingourplant.Itwasreceivedin
good condition by the carrier and was so acknowledged.
CheckforVisibleLossorDamage.Ifthisshipmentshows
evidence of loss or damage at time of delivery to you, in-
sist that a notation of this loss or damage be made on the
delivery receipt by the carrier’s agent.
B. UNPACKING
Check for Concealed Loss or Damage. When a shipment
has been delivered to you in apparent good order, but
concealed damage is found upon unpacking, notify the
carrier immediately and insist on his agent inspecting the
shipment. Concealed damage claims are not our respon-
sibility as our terms are F.O.B. point of shipment.
C. MOVING
Inmovingortransportingdryer,donottipdryerontoits
side.
D. STORAGE/SHUT DOWN
Dryer should not be stored outside (either
packed or unpacked) or exposed to the weather. Damage to
electrical and control components may result.
IMPORTANT: WATER-COOLED UNITS-Iftheunitisshut
down in below freezing temperatures, the water-cooled con-
denser may freeze and cause permanent damage. Condenser
must be drained when the unit is shut down.
IMPORTANT: Do not store dryer in temperatures above 130°F
(54.4°C).

IMPORTANT:READPRIORTOSTARTINGTHISEQUIPMENT
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. ammo-
nia) are not drawn into the air system.
C. Free Air Flow Clearances
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: 40 to 110°F (4 to 43°C).
Water-cooled: 40 to 130°F (4 to 54°C).
E. Installationsinaltitudesabove4500feet(1370meters)
– Dryer is adjusted to operate in altitudes up to 4500 feet
(1370meters).Ifdryerisinstalledinanaltitudeabove
this, and has not been preset at the factory for this altitude,
contact manufacturer’s Service Department.
There shall be no external forces or vibrations
transmitted to the dryer inlet/outlet connections from the piping.
External piping must be properly supported. The installation of
aexibleconnectionorvibrationdampener,withintheair/gas
stream, prior to the dryer is recommended to further reduce the
possibility of damage from vibration or pulsations. Failure to do
so may void the warranty.
NOTE: Outdoor installation – Standard units are designed for
indoor installation. Contact manufacturer if installing outdoors.

1.2 Mounting
Mount the dryer on a level solid surface. Holes are provided in
thedryerbasetopermanentlymountthedryertotheoor.
1.3 Piping Connections
A. AirInlet-Connectcompressedairlinefromairsource
to air inlet. (Reference markings on dryer or see call out
drawing on page 10 for air inlet/outlet connection loca-
tions.)
NOTE:Useback-upwrenchwhenmakingpipingconnec-
tions.
There shall be no external forces or vibrations
transmitted to the dryer inlet/outlet connections from the piping.
External piping must be properly supported. The installation of
aexibleconnectionorvibrationdampener,withintheair/gas
stream, prior to the dryer is recommended to further reduce the
possibility of damage from vibration or pulsations. Failure to do
so may void the warranty.
RefertoSerialNumberTagformaximum
working pressure. Do not exceed dryer’s Maximum Working
Pressure.
NOTE:Installdryerinairsystemathighestpressurepossible
(e.g. before pressure reducing valves).
NOTE: Installdryeratcoolestcompressedairtemperature
possible. Maximum inlet compressed air temperature: 120°F
(49°C).Ifinletairexceedsthistemperature,precooltheair
with an aftercooler.
B. Air Outlet – Connect air outlet to downstream air lines.
NOTE:Useback-upwrenchwhenmakingpipingconnec-
tions.
There shall be no external forces or vibrations
transmitted to the dryer inlet/outlet connections from the piping.
External piping must be properly supported. The installation of
aexibleconnectionorvibrationdampener,withintheair/gas
stream, prior to the dryer is recommended to further reduce the
possibility of damage from vibration or pulsations. Failure to do
so may void the warranty.
C. Bypasspiping–Ifservicingthedryerwithoutinterrupting
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:Usecoppersupplywiresonly.
A. Dryer is designed to operate on the volt-
age, phase, and frequency listed on the
serial number tag.
B. Ifdryerissuppliedwithacordandplug,
install in a receptacle of proper voltage.
C. Electrical entry on larger dryers is through a hole in the
cabinet.Itislocatedontherightsidepanelwhenfacing
the front of the unit. Connect power source to terminal
strip in electrical enclosure as shown on the wiring dia-
gram included with the dryer.
NOTE: Refrigeration condensing unit is designed to run con-
tinuously and should NOT be wired to cycle on/off with the air
compressor.
1.5 Moisture Separator
A. Separator has an external drain which auto-
matically discharges collected condensate.
NOTE:Itmaybedesirabletopipethecon-
densate from the Automatic Drain outlet to a
suitable drain.
B. For manual draining, convenient dryer depressurization,
and drain valve maintenance, a three-way valve assembly
is installed between the drain port on the moisture separa-
tor and the drain valve. On all models, the three-way
valve is mounted to the bottom of the separator vessel
using a pipe union. Review the following for proper drain
function:
• AutomaticDraining-Valvehandleshouldbepositioned
parallel to the valve body (as shown), with the arrow
onthehandlepointingtowardthedrainvalve.Inthis
position,condensatewillowfromthebowltothedrain
valve.
• DrainIsolation(Shutdown)-Valvehandleshallbe
turnedperpendiculartothevalvebody(rotate90°).In
thisposition,condensateowisshutoff.
Pipe Union 3-Way Valve
Manual Discharge Line
Solenoid Valve
Automatic Discharge Line
• ManualDraining-Drainvalvehandleshallberotated
slightly past the drain isolation position to allow
throttling through the valve for manual discharge and
depressurization.
• NOTE: The pipe union 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.

Ifwaterispresentdownstreamofthedryer,
always verify that any condensate drains installed upstream of
the dryer are draining properly before attempting to readjust
the LED setting.
1. For minimum inlet air pressures that fall between column
values, the setting for the lower pressure is recommended.
(i.e. select the 300 psi column values for 324 psi inlet pres-
sure listed in Table 1.)
2. Where the dryer is consistently operating at less than max-
imum capacity, it may be possible to increase the LED set
point to minimize air loss. Discretionary adjustments to the
dryer should only be made on a hot, humid day when the
maximumexpectedairloadisowingthroughthedryer.
Failure to do so may prevent the condensate from draining
completely when operating under peak load conditions.

handle when compressed air to be dried is at 350 psig and
90°F; ambient air temperature is 80°F?
