HOTTANKPRINCIPLESOFOPERATION


AllWaterlogicHotTankshaveabuiltinVentor
ExpansionChamberinthetopofthetankexceptfor
WL270(GF)units.

TheVentChamberallowsforexpansionofthewater
whenitisheated.

Thechambersareseparatedbyawelded‐intank
baffle.

Wateralwaysflowsintothebottomofthetankand
outthetoptothefaucet.

TheHotTankoutlettubehasarestrictorinitsbase.
Thisensuresthereservoirisalwaysfullbyallowing
morewaterinthanout.

Thereisasmallholeinthesideofthetankoutlettube
thatallowsairandwatertopassintothevent
chamberasitisheated.

Waterintheventchamberissuctionedbackthrough
theoutlettubeventholewhenwaterisdispensed.

Expansionofwaterasitisheatedinthereservoirwill
pushthewateroutthefaucetwhentheoutlettube
ventholebecomespluggedwithdebrisorscale.

ThesmallOutletVentHoleissusceptibletoscalebuild
upandisakeyindicatorthatdescalingisrequired.

ItiscriticaltodescaletheHotTankthroughthevent
lineandoutletlineonaregularbasistopreventthis
problem.

Descalingthroughtheinletand/oroutletlinesonly
willnotcleantheventchamberandoutletventhole
