1) INSTALLATION
1.1) Pre-installation instructions
The cycle times, sequence of cycles, salt dose refill time and exchange capacity are preset to default by
OEM. The dealer must guide the installer to change the values according to the hardness, day override
and time of regeneration.
WATER TEST
Hardness gpg
Iron ppm
pH number
*Nitrates ppm
Manganese ppm
Sulphur yes/no
Total Dissolved Solids
Installer must program the valve to recommended hardness, Day override and time of regeneration. Set
time of day, read normal operating displays, read power loss and error displays.
1.2) General Installation and Service Warnings
The softener is designed so that it can be installed easily with minor plumbing changes on
previous plumbing.
The piping must be clamped properly and the weight of the plumbing must not be on the
softener.
Do not use any kind of lubricant including silicone. A silicone based lubricant can be only used on
O- Rings but not necessary.
The nuts and caps can be fastened and unfastened by hand or the plastic service wrench. Do not
use pipe wrench to tighten the caps and nuts.
1.3) Site Requirements
Water Pressure: - 40-110 psi
Water Temperature: - 40-110°F (4.4-43°C)
Electrical- 115/120 V, 60Hz Uninterrupted Outlet
Current required is 0.5 Amperes
The plug-in transformer is for dry locations only
The tank should be on a firm level surface

Well Water Installation Municipal Installation
1) The softener must be close to drain as much as possible.
2) The salt must be refilled in brine tank with frequency stated by dealer.
3) The water heater’s inlet and outlet must be at least 10ft away from softener.
4) The unit including the drain must be located in a room temperature above 33° F.
5) Never let the vacuum occur in tank this may cause implosion and leakage. If vacuum occurrence
is expected than vacuum breaker must be installed in line.
1.7) Plumbing
The bypass valve must be installed on the control valve.
The outside tap water must be bypassed from the softener.
The shutoff valve must be installed at the inlet of unit’s bypass valve.
The primer, solder or solder flux must not get on the O-rings.
After soldering the lines must be cooled before installing the O-Rings, nuts and caps.
If the electrical system is grounded to the plumbing than copper strap must be connected
between inlet and outlet as shown in figure above.
The plumbing must be done by following the local plumbing codes.
1.8) Brine Line Connection
Install the 1/2” or 3/8” O.D. Polyethylene tube according to specification sheet from the brine tank to
the control valve.

1.9) Overflow Line Connection
The overflow drain line is used where overflow of the brine tank can damage the floor finishing or
structure. The brine tank line is equipped with safety float valve which prevents the overflow so, the
overflow line is only used in case is overflow float valve fails. The overflow line will transfer fluid from
brine tank to the drain hence prevents the spillage.
1.10) Drain Line
The size of the drain must be according to the specifications.
Leave minimum of 6” gap between flow control fitting and solder joints. The gap less than this
can damage the flow control.
Use ¾” or 1” tubing for drain line according to the specifications.
If the drain line is elevated and then emptied into the drain below the level the of control valve
the 7” loop should make at the end of drain line.
The air gap between the drain and the end of the drain line must be twice the diameter of the
tube.
The strap must be tied at the end to secure the line.

1.11) Bypass Valve
The inlet and outlet handles point in the direction of flow
indicated by the engraved arrows on the control valve.
Water flows through the control valve for normal
operation of a water softener. During the regeneration
cycle this position provides regeneration water to the unit,
while also providing untreated water to the distribution
system
The inlet and outlet handles point to the center of the
bypass. The system is isolated from the water pressure in
the plumbing system. Untreated water is supplied to the
building
