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
properly.

(~7:00tothe~5:00positions).

Youshouldbeabletoturnthescrewfromthefactorysetpointof41°F
(~12:00position)about45degreesclockwise(2:30onaclock)toreduce
