Inspect Shipment The parts required to assemble and install the unit are included in a bag. Thoroughly check the water softener for possible shipping damage and parts loss. Also inspect and note any damage to the shipping carton. Remove and discard (or recycle) all packing materials. To avoid loss of small parts, we suggest you keep the small parts in the parts bag until you are ready to use them.
Specifications & Performance Claims This model is efficiency rated. The efficiency rating is valid only at the minimum salt dose. This system has a demand initiated regeneration (D.I.R.) feature that complies with specific performance specifications intended to minimize the amount of regenerant brine and water used in their operation.
Before You Start = The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, nighttime pressure may exceed the maximum. Use a pressure reducing valve if necessary (Adding a pressure reducing valve may reduce the flow). If your home is equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes and laws.
Installation Requirements Location Requirements Consider all of the following when selecting an installation location for the water softener. = Do not locate the water softener where freezing temperatures occur. Do not attempt to treat water over 120ºF. Freezing temperatures or hot water damage voids the warranty. = To condition all water in the home, install the water softener close to the water supply inlet, and upstream of all other plumbing connections, except outside water pipes.
Installation Requirements Valve Drain Requirements Using the flexible drain hose (included), measure and cut to the length needed. Flexible drain hose is not allowed in all localities (check your plumbing codes). If local codes do not allow use of a flexible drain hose, a rigid valve drain run must be used. Purchase a compression fitting (1/4 NPT x 1/2 in. minimum tube) and 1/2" tubing from your local hardware store. Plumb a rigid drain as needed (See Figure 6).

Installation Instructions Step 5. Complete Inlet and Outlet Plumbing Measure, cut, and loosely assemble pipe and fittings from the main water pipe to the inlet and outlet ports of the water softener valve. Be sure to keep fittings fully together, and pipes squared and straight. Be sure hard water supply pipe goes to the water softener valve inlet side. NOTE: Inlet and outlet are marked on the water softener valve. Trace the water flow direction to be sure hard water is to inlet.
Installation Instructions Step 6. Cold Water Pipe Grounding CAUTION: The house cold water pipe (metal only) is often used as a ground for the house electrical system, The 3-valve bypass type of installation, shown in Figure 8, will maintain ground continuity. If you use a plastic bypass valve at the unit, continuity is broken. To restore the ground, do the following: 1.

Connecting the System to Wi-Fi Step 1. Download the iQua™ App Go to the App Store or Google Play and download the iQua™ app. This must be installed on your phone to set up an account and connect your water softener to the “cloud”. Step 2. Set Up Your Account 1. Activate the iQua™ app. 2. On the welcome screen, click Create an Account. Step 3. Put Water Softener Control into Connect Mode 1. If you haven’t already done so, program the water softener with time, hardness, salt level, etc.

Controller Features Optional Settings: = Salt Efficiency = Clean Feature = Clean Feature Minutes = Maximum Days Between Regenerations = 97% Feature = 12 / 24 Hour Clock = Backwash & Fast Rinse Times 1. To set any of these options, press and hold the SELECT button for 3 seconds until “000” shows in the display. California Efficiency Requirement Your Morton® Water Softener has a “High Efficiency” feature with an ON or OFF setting.
continued from previous page Controller Features However, you can adjust this time from 1 to 30 minutes in length. To change this cycle time, use the p UP button to increase the time, or the q DOWN button to shorten the time. If no change is desired, continue to next step. 4. Press SELECT again to display the “Recharge Days” screen. FIG. 48 FIG. 50 12 or 24 Hour Clock: All time displays are shown in 12 hour (AM/PM) time format at the default setting.
Power Outage Memory Controller Features If electrical power to the softener is interrupted, the time display is blank, but the electronic controller keeps correct time for several hours. When power is restored, you must reset the present time only if the display is flashing. All other settings are maintained and never require resetting unless a change is desired. If the time is flashing after a long power outage, the softener continues to work as it should to provide you with soft water.
Refilling with Salt Routine Maintenance Lift the salt lid and check the salt storage level frequently. If the water softener uses all the Morton® Clean and Protect™ or Clean and Protect™ Plus Rust Defense™ Pellets before you refill it, you will experience hard water. Until you have established a refilling routine, check the salt every two or three weeks. Always add if less than 1/4 full. Be sure the brinewell cover is on.
Routine Maintenance Cleaning the Nozzle & Venturi A clean nozzle & venturi (See Figure 56) is a necessity for the water softener to work properly. This small component creates the suction to move brine from the brine tank, into the resin tank. If it should become plugged with sand, silt, dirt, etc., the water softener will not work, and hard water will result.
Troubleshooting Automatic Electronic Diagnostics This water softener self-monitors electronic components and circuits for correct operation. If a malfunction occurs, an error code appears in the display. Error Codes 01, 02, 03, 04 & 05: FIG. 58 These are the water softener error codes unrelated to the optional water shutoff valve. While one is in the display, the SELECT button remains operational so the service person can perform the Manual Advance Diagnostics, below, to further isolate the problem.
Troubleshooting Resetting to Factory Defaults To reset the electronic controller to its factory default for all settings (time, hardness, etc.): 1. Press the SELECT button and hold it until the display changes twice to show “CODE” and the flashing model code. 2. Press the p UP button (a few times, if necessary) to display a flashing “SoS”. FIG. 61 3. Press the SELECT button, and the electronic controller will restart. 4. Set the present time, hardness, etc., as described on pages 14-16.

Optional Motorized Water Shutoff Valve The Motorized Water Shutoff Valve (sold separately) may be used with this Morton® Wi-Fi connected water softener and the iQua™ app to remotely turn off the home’s water supply. For example, you may want to turn off the water when going away on vacation. Install the motorized shutoff valve in the plumbing, upstream of the softener (see page 10), and plug the cable into the softener’s electronic control board with the power off (see page 10 and Figure 63).
