GENERAL PRECAUTIONS
Before you begin installation, read the entire manual. Gather
all materials and tools needed. Improper installation voids
warranty.
WARNING
Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the softener.
WARNING
SODIUM INFORMATION: Water softeners using
sodium chloride for regeneration will add sodium
to the water. Persons who are on sodium-
restricted diets should consider the added
sodium as part of their overall sodium intake.
NOTE: Sodium Chloride or Potassium Chloride are
recommended for regeneration.
NOTE: The efficiency of this softener shall be valid only at the
stated salt dosage calculation is made on 120g.
RECOMMENDATION: We recommend that a qualified plumber
be contracted to make all difficult piping installations.
CAUTION: Softener must be protected against freezing, which
can cause cracking of the softener and water
leakage.
CAUTION: Do not treat water over 43°C because hot water
will damage the softener and void warranty.
CAUTION: Locate the softener within 500 cm of drain.
Drain must be capable of handling a maximum
backwash flow rate of 19 liters of water per minute.
CAUTION: Maximum allowable inlet water pressure is
8 Bars if daytime pressure is around 8 Bars,
nighttime pressure may exceed the maximum.
Use a pressure-reducing valve if necessary. Use a
pressure-reducing valve if necessary.
NOTE: Handle softener with care. Do not turn upside down,
drop, or set on sharp objects.
NOTE: The valve requires a minimum inlet pressure of 2 Bar
at 1.2 m3/h.
NOTE: If you are on a private well system, check minimum
water pressure with an accurate gauge. (Gauges on
older water systems are often inaccurate). Pressure
that is less than 2 Bar may cause low flow rate and
inadequate regeneration, but depending by the
pressure droop of the system.
CAUTION: When connecting your unit, take note that the
inlet, outlet, and drain connections are made in
accordance with state and local plumbing codes.
CAUTION: Do not over-tighten pipe to piping boss.
CAUTION: Due to some homes using piping as a source of
electrical grounding, a grounding strap must be
installed where required.
CAUTION: Do not heat piping if it is in contact with the control
valve.
NOTE: Do not put excessive force on the inlet/outlet drain
connections of the control valve.
NOTE: Do not use pipe joint compound or plumber’s putty
when threading pipe into the piping boss. Use only
Teflon®Tape.
WARNING
Do not use any chemical substance (out off
suggested in Pg. 6) to clean resin or softener
component with out the approval of the producer
Electrical Precautions
WARNING
The unit must be plugged into an outlet.
WARNING
Do not use any extension cords.
WARNING
Locate cord where it cannot be accidentally
unplugged or cause any bodily harm.
WARNING
Electrical components are not waterproof.
CAUTION: Make sure power source matches the rating on the
unit.
CAUTION: Make certain the electrical supply cannot be turned
off accidentally.
NOTE: The outlet you select must not be controlled by a wall
switch.

PRE-INSTALLATION CHECKLIST
Installation by a licensed plumber is recommended.
1. Valves, grounding straps, wire, clamps and wall pipe, are
not supplied with the water softener.
NOTE: Ball or globe valves are recommended.
2. Electrical Requirements: AC 220V, 50 or 60HZ current
supply is required.
CAUTION: Make certain the electrical supply cannot be turned
off accidentally.
3. Location of Softener and Drain: We recommend that the
softener be installed on a sound plumbing system within
500 cm from the drain.
NOTE: Outside faucet should be bypassed and left on
hard water.
4. Bypass Valves: Bypass valves allow you to turn off the
water to your unit but not the water service to your home.
Figure 2
5. Pre-Filtration: To prevent your softener from incoming
sediment and iron particles we recommend the installation
of a pre-filter on the water line going to the unit
INSTALLATION
RECOMMENDATION: We recommend that a qualified plumber
be contracted to make all difficult piping installations.
1. SHUT OFF FUEL SUPPLY TO WATER HEATER. See
manufacturer’s instructions.
2. Shut off all water at main supply valve.
3. Open faucet nearest pump or water meter to relieve
pressure and drain system.
CAUTION: The water filter system should be installed
with the inlet, outlet and drain connections
made in accordance with the manufacturer’s
recommendations and to meet applicable
plumbing codes.
4. Set the water filter in place.Place in a firm concrete floor or
slab base. Be sure unit is reasonably level.
NOTE: Do not shim the tank directly for leveling. If
necessary to shim, fabricate a platform base to
set the tank on and then shim under the platform
base.
5. Shut off the water to the home. Open the highest faucet
in the plumbing system and then the lowest (you cannot
work on pipes with water in them). Make necessary piping
changes for connection of the filter to the plumbing of the
home (see Figure 5).Harmonyfalls softeners are suplied
with 1”BSP connection
6. It is highly recommended that the bypass valve accessory
be installed
Make certain the untreated water piping connects to
the control valve on the right and the softened water is
connected on the left (Figure 4).
Figure 4
7. Connect the inlet and outlet piping. The valve connection
threads are 1” BSP. Be sure you have the incoming water
connected to the right side (Figure 4).
NOTE: Do not use pipe joint compound or plumber’s
putty on the backplate threads. Use only Teflon®
Tape.
NOTE: Do not over-tighten fitting to backplate.
8. Make certain proper piping alignment is maintained. Do
not apply heat to any fitting connected to the conditioner or
damage to the valve may occur.
9. Move conditioner into position and level. Check all
connections for tightness.
CAUTION: To prevent water leaks, connections to softener
must be straight when the tank is leveled
CAUTION: Review Drain Requirements section before
connecting drainlines.
10.Carefully attach valve drain line to drain on the back of the
valve.
CAUTION: Do not raise drain line over 2m from floor

DRAIN REQUIREMENTS
If at all possible, locate the softener for optimum drain line
conditions as follows:
WARNING
To prevent electrical shock, do not place
electrical equipment or electrical cords over or
near the drain.
CAUTION: When running the drain line to a floor drain the
area around the drain may become wet during
the regeneration process. Keep floor drain area
clean at all times to prevent any damage.
NOTE: Some states and/or counties have restrictions when
connecting the drain line to your septic system. Check
with your local authorities first.
• Drain line should be as short as possible.
• If available, a floor drain or sump drain is most desirable.
• An elevated drain installation requires precautions as
detailed under Special Drain Line Situations below.
Typical Drain Hookups (Figure 6)
• Floor drain in basement or utility room. (Holes in drain
cover MUST be kept open.)
• Sump pit. (Sump must NOT discharge to surface watering
of lawn, shrubs, trees, etc.)
• Dry well (if legal).
• Laundry tub or clothes washer drain.
• Sanitary sewer line with sink type trap.

DRAIN REQUIREMENTS continued
Drain Adapter (Figure 7)
A drain adapter should be use to accommodate 1/2” tubing
drain line material.
On tube or hose drain line, use a hose clamp to secure drain
line to barbed fitting. Also, select a firm hose that will not
soften and collapse or kink at high temperature, at suspension
points or at sharp bends. Plumbing codes do not permit a
direct connection into any sanitary or storm drain. An air gap
of at least 5cm is usually required so sewer backup will not
contaminate the system. Clamp the drain line securely to a rigid
surface to prevent it from moving during regeneration. Entire
drain system must be able to handle maximum regeneration
flow of 19 l/min. Drain should not be elevated more than
1.5 m a bove the control valve. If conditions mandate that the
drain must be higher, see discussion of special drain situations
below.
Figure 7
Special Drain Line Situations
On some installations it may be necessary to have the drain
line rise more than 1.5 m above the control valve. Explained
below are special modifications for improving performance
under these adverse conditions.
Figure 8
In cases where drain line empties into an “overhead” sewer
line, a “sink” type trap must be used. Do not connect or seal
drain line to trap. Secure drain line to provide an air gap or use
an air gap device.
Figure 8

regeneration time, the manual regeneration request
shall be cleared.
DISINFECTION OF WATER SOFTENERS
NOTE: Every water softener should be disinfected after
installation; some will require periodic disinfection
during their normal life. In a few cases, disinfection with
every regeneration is recommended.
NOTE: Depending upon the conditions of use, the style of
softener, the type of ion exchanger, and the disinfectant
available, a choice can be made among the following
methods:
Sodium or Calcium Hypochlorite
5.25% Sodium Hypochlorite
IMPORTANT: Do not use any other chemical substance with
out manufacturer approval.
1. Dosage: 0.022 fluid liters
2. Proceed with the normal regeneration.
ADDING SALT
NOTE: Your softener comes pre-charged and will supply you
with a day or two of soft water. Salt must be added to
the salt tank for the system to regenerate properly. This
must be done within the first 24 - 28 hours. For the
start up use the 10Kg salt bag included
Types of Salt
Any pellet type salt is recommended due to its cleanliness
and availability. Other salts such as block, solar and rock salt
can be used; however, they may alter performance or cause
maintenance problems.
Amount of Salt
One tank units have a salt capacity of (see table pag 2).
You are not required to fill your salt tank to capacity. It is
recommended that the salt level in the salt tank always be
above the water level in the tank. This will assure that the unit
always has the correct salt dosage when it regenerates.
MAINTENANCE AND REPAIR
This unit is designed and constructed to treat the most difficult
of water. Various screens have been included in the system to
protect orifices.
BEFORE doing any service work, be sure all screens are clean
and will pass water. Periodic cleaning of the screens will insure
long-term unit performance.
Lack of treated (soft) water is constant.
1. No salt in tank — Add salt to tank
2. Dirty screens — Clean screens
3. Faulted timer motor — Replace
Lack of treated (soft) water is intermittent.
Intermittent is often indicated by untreated water from the
heater (hot water) while the cold water tastes good. Intermittent
indicates excess water usage, a change in water chemistry,
or an improper frequency of regeneration. Review entire
application.
1. Low salt setting — Adjust brine value
2. Water consumption increased — Check for household leaks
3. Too infrequent regenerations — Review sizing and
reprogram timer
Brine tank overflow
1. Plugged screens or injector — Clean
2. Defective Brine Valve — Clean or replace
3. Defective timer or timer motor — Replace
