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.(Referencemarkingsondryerorseecallout
drawingonpage13forairinlet/outletconnectionloca-
tions.)
NOTE: Customer piping needs to be properly supported.
Useback-upwrenchwhenmakingpipingconnections.
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.
NOTE: Customer piping needs to be properly supported.
Useback-upwrenchwhenmakingpipingconnections.
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 volt-
age,phase,andfrequencylistedonthe
serial number tag.
B. 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: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: It may be desirable to pipe the con-
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basepan.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 drain valve. In this
position,condensatewillowfromthebowltothedrain
valve.
• DrainIsolation(Shutdown)-Valvehandleshallbe
turnedperpendiculartothevalvebody(rotate90°).In
thisposition,condensateowisshutoff.
Solenoid Valve
Automatic Discharge
Line
Manual Discharge Line
3-Way Valve
Drain Inlets
• 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: Discharge is at system pressure. Drain line should be
anchored.
NOTE: Condensate may contain oil. Comply with applicable
laws concerning proper disposal.
