#1TANKLESSwaterheaterscanbeproblematicforcommercialdishmachines.TheADSmodelET‐AF
dishmachinerequiresthefullcycleamountofwater(1.7gallons)suppliedwithin7seconds.Ithasbeenthe
experienceofADSthattanklesssupplysystemsrequiremultipleunitsplumbedinsequencewitha
recirculationloop
toachieveproperpressureandtemperature.
Checkwiththetanklesswaterheatermanufacturer,theymayrecommendastoragetanktoguarantee
properflowandlinepressuretothemachine.Failuretoprovideadequatewaterquantity,pressureand
temperaturetothemachinewillcausethemachinetofunctionimproperlyandisnottheresponsibilityof
ADS.ImproperlyinstallingADSequipmentinthismannercouldvoidthewarranty.Allcostsassociatedwith
providinganadequatewatersupplytothemachineisthesoleresponsibilityoftheuser.
