RECEIVING, MOVING, AND UNPACKING
A. RECEIVING
Thisshipmenthasbeenthoroughlychecked,packedand
inspectedbeforeleavingourplant.Itwasreceivedin
goodconditionbythecarrierandwassoacknowledged.
CheckforVisibleLossorDamage.Ifthisshipmentshows
evidenceoflossordamageattimeofdeliverytoyou,in-
sistthatanotationofthislossordamagebemadeonthe
delivery receipt by the carrier’s agent.
B. UNPACKING
CheckforConcealedLossorDamage.Whenashipment
has been delivered to you in apparent good order, but
concealeddamageisfounduponunpacking,notifythe
carrier immediately and insist on his agent inspecting the
shipment. Concealed damage claims are not our respon-
sibilityasourtermsareF.O.B.pointofshipment.
C. MOVING
In moving or transporting dryer, do not tip dryer onto its
side.
D. STORAGE/SHUT DOWN
Dryer should not be stored outside (either
packedorunpacked)orexposedtotheweather.Damageto
electrical and control components may result.
IMPORTANT: WATER-COOLED UNITS-Iftheunitisshut
downinbelowfreezingtemperatures,thewater-cooledcon-
densermayfreezeandcausepermanentdamage.Condenser
must be drained when the unit is shut down.
IMPORTANT: Do not store dryer in temperatures above 130°F
(54.4°C).

1.3 Piping Connections
A. AirInlet-Connectcompressedairlinefromairsource
toairinlet.(Referencemarkingsondryerorseecallout

tions.)
NOTE: Customer piping needs to be properly supported.
Useback-upwrenchwhenmakingpipingconnections.
RefertoSerialNumberTagformaximum
workingpressure.Donotexceeddryer’sMaximumWorking
Pressure.
NOTE: Install dryer in air system at highest pressure possible
(e.g.beforepressurereducingvalves).
NOTE: Install dryer at coolest compressed air temperature
possible.Maximuminletcompressedairtemperature:120°F
(49°C).Ifinletairexceedsthistemperature,precooltheair
withanaftercooler.
B. AirOutlet–Connectairoutlettodownstreamairlines.
NOTE: Customer piping needs to be properly supported.
Useback-upwrenchwhenmakingpipingconnections.
C. Bypasspiping–Ifservicingthedryerwithoutinterrupting
the air supply is desired, piping should include inlet and
outlet valves and an air bypass valve.
D. Watercooledmodels–coolingwaterinletandoutlet
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 volt-
age,phase,andfrequencylistedonthe
serial number tag.
B. Electrical entry on larger dryers is through
a hole in the cabinet. It is located on the right side panel
whenfacingthefrontoftheunit.Connectpowersource
to terminal strip in electrical enclosure as shown on the
wiring diagram included with the dryer.
NOTE:Refrigerationcondensingunitisdesignedtoruncon-
tinuously and should NOTbewiredtocycleon/offwiththeair

1.5 Moisture Separator
A. Separatorhasanexternaldrainwhichauto-
matically discharges collected condensate.
NOTE: It may be desirable to pipe the con-
densatefromtheAutomaticDrainoutlettoa
suitable drain.
B. Formanualdraining,convenientdryerdepressurization,
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
valveismountedtothebasepan.Reviewthefollowing
forproperdrainfunction:
• AutomaticDraining-Valvehandleshouldbepositioned
paralleltothevalvebody(asshown),withthearrow
on the handle pointing toward the drain valve. In this
position,condensatewillowfromthebowltothedrain

NOTE: Discharge is at system pressure. Drain line should be
anchored.
NOTE: Condensate may contain oil. Comply with applicable
laws concerning proper disposal.
