YOUHAVERESPONSIBILITIESTOO

Thisinstallation,operationandmaintenancemanualcannotcovereverypossibility,situationor

eventuality.Regularservice,cleaningandmaintainingtheequipmentisnecessary.Ifyouarenotcapable

ofperformingthesetasks,hireaqualifiedservicespecialist.Failuretoperformthesedutiescancause

propertydamageand/orharmtothebuildingoccupantsandwillvoidthemanufacturers’warranty.

INTRODUCTION

EngineeredAirunitsarehighqualityproductsdesignedandmanufacturedtoprovidemanyyearsof

trouble‐freeoperation.Werecommendthatthismanualbereadthoroughlytoensureproperinstallation,

efficientoperationandpropermaintenanceofthisequipment.Thesubmittalrecordisconsideredtobe

partoftheInstallation,OperationandMaintenanceManual.Pleasereportanyomissionstothenational

servicemanager.



Natatoriums(Indoorswimmingfacilities)haveinherentissueswithhighrelativehumiditywithinthe

buildingenvelope.Excessivehumiditywithinastructurecancompromisethebuildingintegrityorpromote

thegrowthofmoldandmildew.Itisnecessarytocontroltherelativehumiditytominimizetheassociated

problems.Theprimaryfunctionofapooldehumidifier(PDseriesunit)istomanagethehumiditylevels

withinthefacilities.Thishelpstoreducetheadverseeffectsofhighhumidityonthebuilding.

Additionalfunctionsforthepooldehumidifiermayincludespaceventilation,comfortheatingand/or

coolingandpoolwaterheating.



ControlisnormallyaccomplishedbymeasuringthesensibleroomtemperatureandtheRH%.Thisisthen

calculatedbythecontrollertodeterminethedewpoint.



SAFETYPRECAUTIONS

Read,understandandfollowthecompletemanualbeforebeginningtheinstallation,includingallsafety

Improperinstallation,adjustment,alteration,serviceormaintenancecancause

propertydamage,injuryordeath.Readtheinstallation,operatingandmaintenance

instructionsthoroughlybeforeinstallingorservicingthisequipment.

Warning:Thisunitisconnectedtohighvoltages.Electricalshockordeathcouldoccurif

instructionsarenotfollowed.Thisequipmentcontainsmovingpartsthatcanstart



ConsulttheSubmittalRecordforspecificunitmounting.EngineeredAirunitsareconstructedforthree

typesofmounting:



1. Basemounting–ConsulttheSubmittalRecordfortypeofmounting.Unlesstheunitisspecifically
