PRESSURETESTING
1.Dotheprecedingsanitizingproceduresbefore
pressuretesting.
2.Openthewatersupplyshutoff valvetotheRO.
3.Openthemainwatersupply valveandseveral
housefaucetstopurgeairfromthesystem.Close
faucetswhenwater runs smooth.
4.Inabout2 hours,pressurewill start to buildinthe
ROsystem.Then,carefullycheckallfittings andcon-
nectionsforwaterleaks.Correctleaksifanyare
found.
Note:Whenthesystemisfirstpressurized,water
may‘‘spurt’’fromthefaucetairgapholeuntil airis
expelledfromtheROsystem.
PURGING ROMEMBRANE
Importantpurginginstructions:TheROcartridge
contains a food gradepreservativethatyoushould
cleanfromitbeforeusingwaterfromthesystem.The
preservativewill giveproduct wateranunpleasant
tasteandodor.
1.Allow thestoragetanktofill forabout4hours.
Then,opentheROfaucetuntilthetankisemptyand
flowstops.
2.ClosetheROfaucetandallow thetanktofillagain
