Removing Condensate

Condensatemustbedrainedfromthedryertopreventre-

entrainment. The dryers are equipped with automatic drain

valves and internal drain hoses up to the drain connections

on the dryer cabinets. The user must install a separate

dischargelineatthedrainconnectiontocarryoffcondensate

to an environmentally approved condensate collection/

disposalsystem.Pipingorcoppertubing1/2inchorlarger

isrecommendedforcondensatedischargelines.Installthe

drain lines so that condensate can be seen as it drains.

Electrical Connections

ThedryersareconstructedaccordingtoNEMAType1

electrical standards. Field wiring must comply with local and

nationalre,safetyandelectricalcodes.Installationmust

beinaccordancewiththeNationalElectricalCode.Conrm

that your line voltage is the same as the voltage listed on the

dryerdataplate.RefertoFigure1forelectricalschematics.

Operation of dryers with improper line

voltage constitutes abuse and could affect the dryer

warranty.
