A. SYSTEM SPECIFICATIONS & DIMENSIONS
* Note: Install pressure regulator and water hammer arrestor if pressure exceeds rated pressure at any time.
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.
These softeners conform to NSF/ANSI 44 for the specific performance claims as verified and substantiated by test data. These models are efficiency
rated. The efficiency rating is valid only at the stated salt dose and maximum service flow rate. They have a demand initiated regeneration (D.I.R.)
feature that complies with specific performance specifications in-tended to minimize the amount of regenerant brine and water used in their
operation. These softeners have a rated softener efficiency of not less than 3350 grains of total hardness exchange per pound of salt (based on sodium
chloride) and shall not deliver more salt than their listed ratings. The rated salt efficiency is measured by laboratory tests described in NSF/ANSI
Standard 44. These tests represent the maximum possible efficiency that the systems can achieve. Operational efficiency is the actual efficiency after
the system has been installed. It is typically less than the efficiency due to individual application factors including water hardness, water usage, and
other contaminants that reduce the softener’s capacity.
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.
B. 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 an automatic 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. It then goes through a final rinse & refills the salt tank with water for the next regeneration.
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. The unit automatically calculates when to regenerate based on
your water hardness and use.
C. SAFETY PRECAUTIONS AND CAUTIONS BEFORE INSTALLATION
Follow all applicable province/state and local regulations.
Handle your water softener carefully. Do not lie on side, turn upside down, drop or drag.
This unit requires softener salt (sodium chloride) to regenerate. Softener salt is available at most retailers. Persons
on sodium restricted diets should consider the added sodium as part of their overall intake. Potassium chloride can
be used as an alternate in such situations. Please consult Rainfresh technical support.
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. Use only lead-free solder and flux.
DO NOT over-tighten metal fittings on to unit connections.
Place the unit 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 cabinet 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 injury.
The unit must be installed in an area where there is reasonable access to the salt tank for regular salt filling.
D. INSTALLATION
Electrical Requirements:
The automatic control valve requires a constant power supply - 110V AC. We recommend a GFI (ground fault
interrupter) outlet within 5 feet of the softener. Extension cords are not recommended.
If water pipes are used to ground electrical system, you will need to install a jumper wire across the filter unit.
Unpacking the unit
The unit includes:
Unpack the unit and discard the plastic air pack inside the unit. Place the unit at the location where you intend to install it.
Stand back and look at the softener to make sure it is standing straight up and not tilted to one side. Make sure your
chosen location will be fairly level, dry, and protected from possible freezing
conditions. The softener can sit directly on the floor and will not corrode. DO
NOT set the softener onto make shift platforms as this can damage the salt tank,
or may cause it to topple.
The system has 3 connections - an inlet, an outlet, and a drain line connection. If
you are looking at the back of the unit (fig 1), the inlet is on the left side.
Warning: Make sure that you have correctly identified the inlet of the system.
REVERSING THE CONNECTIONS WILL RESULT IN RESIN BEADS BEING THROWN
INTO YOUR HOME'S PLUMBING SYSTEM CAUSING DAMAGE TO IT AS WELL AS
THE SOFTENER.
The following pipe can be used for installing your new system - Copper, CPVC, and PEX are the most popular.
1) Softener with
built-in salt
tank and
bypass valve
2) Inlet/outlet elbow fittings (2)
–¾” Male NPT
3) Allen key (for ease of opening
& closing bypass valve)
4) Brine overflow fitting
5) Drain hose (15 ft) with hose
clamp
6) AC power adapter

Plumbing in your softener
If your hot water tank is electric, turn off the power to it to avoid damage to the element in the tank.
If you have a private well, turn the power off to the pump then shut off the main water shut off valve. If you have
municipal water, simply shut off the main valve. Go to a faucet, (preferably on the lowest floor of the house) turn
on the cold water until all pressure is relieved and the flow of water stops.

Position the softener in the desired location. The unit comes with
two 90°¾” male NPT elbow fittings (see fig 1). You can rotate them
at any angle to suit your installation. Make sure that the bypass
valve is in bypass mode as shown in fig 2.
Note: To change the connection fitting, simply remove the locking
clips by hand and pull the fitting out. Insert new fitting and reinstall
locking clip (fig 3).
Plumb in the softener using appropriate fittings.
Unscrew the cabinet top using a screwdriver and move the top
aside, making sure that the electronic cable underneath does not
detach from the circuit board.
Attach the drain hose (15 ft included) to the drain fitting and secure
it with a hose clamp (fig 4) (included).
Run the drain line to a nearby laundry tub, standing pipe or floor
drain (fig 5) and cut off excess tubing.
NOTE ABOUT DRAIN LINE : You can run the drain hose from the unit to
the ceiling joists (max 8 ft ceiling) and run it to the nearest laundry tub
or drain pipe. This can be run up overhead or down along the floor. Use
band clamps to hold the drain tubing in place. If running drain line more
than 15 feet from the softener (max 25 ft), increasing the line size to
3/4" will be required. Please follow your local plumbing & other
applicable codes for where to run softener discharge water. NEVER
MAKE A DIRECT CONNECTION INTO A WASTE WATER DRAIN. A
PHYSICAL AIR GAP OF AT LEAST 1.5" SHOULD BE USED TO AVOID
BACTERIA AND WASTEWATER TRAVELING BACK THROUGH THE DRAIN
LINE INTO THE SOFTENER (see fig 5). If you have other water
conditioners, such as an iron filter, carbon filter, tannin filter etc., RUN
THE DRAIN TUBING FOR EACH UNIT SEPARATELY. DO NOT TEE (COMBINE) DRAIN TUBING FROM OTHER UNITS.
You can also use code-approved air-gap attachments available at most plumbing stores.
Attaching the overflow tubing: If the overflow fitting is not pre-attached to the cabinet, then
drill a ¾” hole on the side of the softener about ¾ of the way from the bottom (fig 6). Insert
the over flow fitting from the outside and tighten the nut from the inside to lock it.
Attach the rest of the drain tubing to the overflow fitting and run to the floor drain with an
appropriate air gap, as shown in fig 5. If you do not have any more drain tubing left, you will
need to purchase extra tubing at your local plumbing retailer. WARNING : DO NOT TEE THE
OVERFLOW TUBING TO THE DRAIN TUBING
Re-attach the cabinet top and secure it with the screws.

The salt tank is pre-connected to the control head. Lift the cabinet lid and add about 5 gallons of water in the salt
tank. This is not a critical level but just helps with the process for the first regeneration. Then add 2 bags (20 Kg
bags) of salt to start with. DO NOT ADD MORE THAN 2 BAGS OF SALT to prevent salt bridging.
Turn main house shut-off valve on slightly and watch for leaks. Ensure a faucet is on somewhere and that its aerator
is removed to avoid clogging from loosened scale in the pipes. If you have no leaks, proceed to the next steps.
Turn on the water supply
Using the Allen key (included), turn the bypass inlet slightly (refer to fig 2) to allow water to run into the unit. The
water should initially fill the tank slowly. Once the tank is full of water, you can open valve fully. This prevents resin
from being pushed up into the control head by the initial surge of water going in.
Make sure there are no leaks in your plumbing before proceeding.
At the nearest cold treated water tap remove the faucet screen and open the faucet.
Using the Allen key (included), open the outlet side of the bypass valve and let water
run a few minutes or until the system is free of any air or foreign material resulting
from the plumbing work. Close the water tap when water runs clean, and then proceed
to start up instructions.
Connect the control valve to the power adapter (fig 7) & connect the adapter to the
power supply.
NOTE: Your unit is not yet ready for service until you complete manual
regeneration (see pages 7-11)

STEP 4: Setting Water Hardness
This value is the hardness value of your water in grains per gallon (GPG). If you have the reading in PPM or mg/L,
simply divide that by 17.1 to get the reading in GPG. You must also add (5 x iron level in PPM) to the hardness value.
HARDNESS VALUE = YOUR WATER HARDNESS + (5 x Iron concentration in PPM)
For example, if your water hardness is 20 GPG and the iron level is 0.3 PPM, the hardness value you enter must be
20 + 5 x (0.3) = 20 + 1.5 = 21.5 GPG
Note: If you do not know your water hardness, please call customer service for details on how to send us a water
sample and receive a free water analysis. In the meantime, you can leave the hardness value at default
setting. You can also visit www.rainfresh.ca for details.
STEP 5: Setting Vacation Mode
This function may be activated during a prolonged absence, such as a vacation for more than 2 weeks. The system
will perform a brief backwash and rinse based on advanced setting. The purpose is to keep the water fresh in the
softener tank and plumbing system.
When you return from vacation, return the holiday mode to "NO".

F. OTHER FEATURES
Control Operation During a Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours. The programmed settings
are stored in a non-volatile memory and will not be lost during a power failure. If power fails while the unit is in
regeneration, the valve will finish regeneration after power is restored. If the valve misses a scheduled regeneration
due to a power failure, it will queue regeneration at the next regeneration time once power is restored.
Safety Float
The brine tank is equipped with a safety float which prevents your brine tank from overfilling as a result of a
malfunction such as a power failure.
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts approximately 2 hours.
During this time, you may hear water running intermittently to the drain.

Manual Bypass
In the case of emergency, such as an overflowing brine tank, you can isolate your water softener from the water
supply using the bypass valve located at the back of the control. To resume soft water service, open bypass valve by
rotating the knobs counterclockwise.
G. MAINTENANCE
Adding Salt
Fill the salt tank only with nugget or pellet salt that is specifically for water softeners only. DO
NOT USE rock salt, road salt or other types of impure salts. Use only high grade water softener
salt (Sodium Chloride). You can use Potassium Chloride but you will need to increase salt settings
(see page 11). Check the salt level monthly. It is important to ALWAYS maintain the salt level
above the water level. To add salt, simply slide the cabinet lid and add the salt directly into the
brine tank. Be sure the brine well cover is on and fill only to the height of the brine well. The salt
tank should never be empty.
DO NOT OVERFILL THE SALT TANK TO THE TOP. Once you can see the water level in the tank, do
not fill more than 2-3 bags of salt.
Preventing and breaking a Salt Bridge
Humidity or wrong type of salt may create a cavity between the water and the salt. This action,
known as “bridging”, prevents the brine solution from being made, leading to your water supply
being hard. If you suspect salt bridging, pour some warm water over the salt to break up the
bridge. Allow at least four hours to produce a brine solution, and then manually regenerate the
softener. This should always be followed up by allowing the unit to use up any remaining salt and then thoroughly
cleaning out the brine tank.
If you are unable to break the bridge this way, take a strong rod and carefully push down the salt, working it up and
down (see fig on the right). Do not pound on the walls of the tank.
If the wrong kind of salt has been used, take it out and fill with nugget or pellet salt.
Care of Your Softener
To retain the attractive appearance of your new water softener, clean occasionally with mild soap solution. Do not
use abrasive cleaners, ammonia or solvents.
Cleaning the Injector Assembly
Sediment, salt and silt will restrict or clog the injector. A clean water supply and pure salt will prevent this from
happening. The injector assembly is located on the right side of the control valve. This assembly is easy to clean.
Shut off the water supply to your softener and reduce the pressure by opening a cold soft water faucet. Using a
screwdriver, remove the two screws holding the injector cover to the control valve body. Carefully remove the
assembly and disassemble as shown in Figure 6. The injector orifice is removed from the valve body by carefully
turning it out with a large screwdriver. Remove the injector throat the same way. Carefully flush all parts including
the screen. Use a mild acid such as vinegar to clean the small holes in the orifice and throat.
Reassemble using the reverse procedure.

J. Limited Warranty
This “C” Series Softener System is warranted to the original Consumer purchaser for a period of one (1) year, from the date
of purchase, against defects in materials or workmanship. The electronic controls and mineral tank are warranted for 5 and
10 years respectively against defects in materials or workmanship. The company's obligation under this warranty shall
consist of repair or replacement, at its option, of any part found by company inspection to be defective, provided that the
product has not been misused, abuse, altered or damaged by Consumer with respect to the original installation, as
determined by the company. This warranty will not apply if water passing through the System has a) Turbidity / Suspended
Solids > 5 ppm (mg/l). b) Hydrogen Sulphide concentrations greater than 0.05 ppm (0.05 mg/l). c) Iron concentration greater
than 0.5 ppm (0.5 mg/l) or Manganese greater than 0.05 ppm (0.05 mg/l), f) Tannins or colour. This limited Warranty applies
only to a unit when returned to the Warrantor at the owner’s expense and in accordance with shipping instructions received
from the Warrantor. This warranty does NOT cover, and is intended to exclude, any liability on the part of Envirogard for any
incidental damages, consequential damages, labour charges or any other costs incurred in connection with the purchase,
installation, use, maintenance or repair of the system whether under this warranty or any other warranty implied by law.
Some provinces/states do not allow the exclusion of incidental or consequential damages, so the above limitation or
exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights, which vary
from province/state to province/state. This warranty applies only to softeners purchased in Canada or the U.S.A.
