17.RunOn–Watercontinuestodispenseoutoffaucetafterreleasingthedispense
button

Reason
“RunOn”or“CarryOn”ispresentinallWaterlogicpressurefedunitswithoutoutletsolenoids.

“RunOn”isdefinedistheamountofwaterthatcontinuestodispenseoutofthefaucetafter
releasingthedispensebutton.

RunOnexistsbecausethetankspressurizeaswaterisbeingdispensed.EveryWaterlogictankhasan
outletrestrictortoensurethetanksremainfullofwaterandwateriscontrolledasitisreleasedtothe
faucet.Theinletsolenoidcontrolsflowintothetanks.Thetankswill“depressurize”oncethe

thefaucetasthetankdepressurizestoatmosphericconditions.

Typical“RunOn”is2‐3seconds.

“RunOn”canbereducedbyinstallingapressurelimitingdevice.

HOTTANKDESCALINGINSTRUCTIONS

TheHotTankrequiresremovalofmineraldeposits(descaling)onaregularbasis.Typicallydescaling
shouldtakeplaceevery6to12monthstopreservethelong‐termhealthofyourunit.

Usenon‐toxiccleanersuchasScaleKleen,DEZCAL,20%CitricAcidSolution,orUndilutedVinegar
Solutiontoremovemineraldepositsasdirectedbythemanufacturerdependinguponfiltrationand
localwaterconditions.

Descalingisanimportantprocessthatremovescalciumdeposits,orscale,thatcanbuildupinsidea
tankovertime.Calciumandscaleisnon‐toxicbutleftunattendedwillhinderyourunit’s
