HOW YOUR WATER CONDITIONER WORKS
Your Rainfresh Softener re oves hardness using a process called Ion Exchange. In this process, when hard water flows
through the unit, hardness-causing inerals such as Calciu & Magnesiu , are trapped by the edia (called Resin) and an
equivalent a ount of sodiu ions are released into the water. When the capacity of the resin to trap hardness inerals is
exhausted, the unit is re-charged by softener salt in a process called Regeneration. During regeneration, the unit first
backwashes to re ove any sedi ent, rust or other particulates, that ay have accu ulated in the unit. This is followed by
introduction of a saturated salt solution (brine) that bu ps off the trapped hardness to drain and recharges the resin with
sodiu .
Once you progra the unit at the ti e of installation, the regeneration process happens auto atically. All you need to do is
to ensure that there is always enough salt in the salt tank.
CAUTIONS BEFORE INSTALLATION
-Install a pressure regulator and water ha er arrestor if pressure exceeds axi u rating at any ti e. Note: If
dayti e pressure is over 80 psi, night ti e pressure ay exceed axi u pressure rating.
-Do not install on water that is icrobiologically unsafe without adequate disinfection before or after the unit. For
effective disinfection install a Rainfresh Drinking Water Syste or Rainfresh UV disinfection syste .
-For use on cold water only.
-Only use thread seal tape (Teflon® tape) for fitting connections into unit. DO NOT USE pipe dope or chemical
sealants.
-If water pipes are used to ground electrical syste , install ju per wire (#4 gauge solid copper wire) across the unit
to aintain proper grounding of your electrical syste
-rotect your unit from freezing - drain the unit if freezing te peratures exist.
-NOTE: IF SOLDER TY E FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections. All solder joints
should be ade before joining pipe to filter head.
-DO NOT over-tighten etal fittings on to unit connections.
-Follow all applicable province/state and local regulations.
-You will need softener salt with this unit (not included). Softener salt is sold at ost retailers.
-Place the unit & salt tank on a flat level surface. Do not place shi s under the unit to level it. The weight of the unit
full of water and salt can cause the tank to crack at the shi .
-The unit should only be oved by 2 or ore people due to heavy weight. Failure to do so can result in back or other
injury.
-The unit ust be installed in an area where there is reasonable access to the salt tank for regular salt filling.
At the stated service flow rates, the pressure drop through
these devices will not exceed 15 psig.
