Feed Water Quality:
Iron < 0.5 PPM; Manganese < 0.05 PPM ; Turbidity < 1 NTU ; Free Chlorine < 0.5 PPM ; Hydrogen Sulphide – Nil ; Organics – Nil.
If feed water quality exceeds above limits, please call Rainfresh for advice on additional treatment that may be necessary.
HOW YOUR WATER CONDITIONER WORKS
Your Rainfresh Softener removes hardness using a process called Ion Exchange. In this process, when hard water flows
through the unit, hardness-causing minerals such as Calcium & Magnesium, are trapped by the media (called Resin) and an
equivalent amount of sodium ions are released into the water. When the capacity of the resin to trap hardness minerals is
exhausted, the unit is re-charged by softener salt in a process called Regeneration. During regeneration, the unit first
backwashes to remove any sediment, rust or other particulates, that may have accumulated in the unit. This is followed by
introduction of a saturated salt solution (brine) that bumps off the trapped hardness to drain and recharges the resin with
sodium.
Once you program the unit at the time of installation, the regeneration process happens automatically. 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 hammer arrestor if pressure exceeds maximum rating at any time. Note: If
daytime pressure is over 80 psi, night time pressure may exceed maximum pressure rating.
- Do not install on water that is microbiologically unsafe without adequate disinfection before or after the unit. For
effective disinfection install a Rainfresh Drinking Water System or Rainfresh UV disinfection system.
- 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 system, install jumper wire (#4 gauge solid copper wire) across the unit
to maintain proper grounding of your electrical system
- Protect your unit from freezing - drain the unit if freezing temperatures exist.
- NOTE: IF SOLDER TYPE FITTINGS ARE USED DO NOT USE torch near inlet/outlet connections. All solder joints
should be made before joining pipe to filter head.
- DO NOT over-tighten metal 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 most retailers.
- Place the unit & salt tank on a flat level surface. Do not place shims under the unit to level it. The weight of the unit
full of water and salt can cause the tank to crack at the shim.
- The unit should only be moved by 2 or more people due to heavy weight. Failure to do so can result in back or other
injury.
- The unit must 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.
• The manufacturer reserves the right to make product
improvements which may deviate from the specifications
and descriptions stated herein, without obligation to
change previously manufactured products or to note the
change.
Feed Water Temperature = 4°C - 38°C (39 - 100°F)
• Operating Pressure = 25 (172 kPa) - 100 PSIG (689 kPa)*
• Voltage = 110 V AC
* Note: Install pressure regulator and water hammer arrestor if pressure
exceeds rated pressure at any time.
