When water leaks from this hole (air gap hole) this means the drain line which runs from the base of the reverse osmosis faucet to the kitchen sink drain is clogged and needs to be cleaned.

Some gurgling from your reverse osmosis is normal. If the noise is excessive you may need service. If this is a new installation it may take seven to tens days for all of the air to come out of the system then it will quiet down.

In most situations cloudy water is caused by air in the water, it is not harmful. Take a sample of the water in a clear container; if the bubbles rise to the top and form a white ring and the water is clear, this is air. If particles form and sink to the bottom call for service.

The reverse osmosis supplies approximately ½ as much pressure when compared to the incoming house pressure, therefore when the system is connected to the refrigerator there will be less pressure than if hooked up to house supply. Remove the refrigerator filter and replace it with the factory plug to help increase pressure.

The most common cause of reverse osmosis tubes banging is backpressure caused from some other water source. In most cases if you have a swimming pool with auto filler the float is turning off and on rapidly causing the reverse osmosis lines to bang. It could also be your water conservation valve that is bad.

The meter that comes with the KR15 system measures total dissolved solids (TDS) in the water. Take readings of the tap water and the reverse osmosis water and follow the formula below to obtain the percentage of removal. If the percentage is above 70% the membrane is working ok. R/O TDS reading divided by tap water TDS reading – 1 = % of removal

Filters in a reverse osmosis system should be changed annually to prevent the build up of foreign material that the filters trap.

After a filter change the ice maker can be turned back on eight hours after the second tank draining.

Before measuring the pressure in the tank it must be empty, after this is done the pressure in most cases should be set at 10-12psi.

Average membrane life is two to five years. The more a system is used the longer a membrane tends to last.

The length of time you are gone is the determining factor. If you are going to be gone for more than 30 days the system will either need to be drained and allowed to refill, this is best if done every two weeks, or the membrane removed for cold storage in the refrigerator. If you leave for the summer it is best to shut the system down and remove and discard the filters, have the unit serviced when you return. if you are gone less than 30 days there is no need to do anything except shut the unit off if you wish to. Upon your return drain the tank and allow it to refill.

Your water softener is a fully automatic Demand Initiated, metered system. This means the softener meters, or keeps track of, the water used in the home. It uses this information to determine when to perform the regeneration, or cleaning cycle. The control of the softening process automatically adjusts to your water use. For example, if you have company and your water use increases substantially, the softener will adjust to insure you don’t run out of soft water. If you go away for a time and are not using any water in the home, the softener will adjust again and not perform a regeneration cycle thereby saving salt and water.

Your softener uses about as much electricity to operate as an alarm clock. Other costs include water and salt but vary depending on how much water you use. A typical household will use about 1 to 1.5 bags of salt per month (about $3-4.50/bag).

Basically, salt is salt. However, some makes of salt contain more dirt in the bag than others. We recommend Morton™ or Diamond Crystal™ salt pellets. Salt is readily available at most grocery stores and home improvement centers. Solar Salt not recommended.

Depending on the system you purchased, somewhere between 40 and 60 gallons.

Potassium can also be used in the water softener. When Potassium is used however, the softener control valve will need to be adjusted. Add 3 grains to the feed water hardness setting i.e. feed water = 18 grains + 3 for potassium = 21 grains entered for the feed water setting. Also keep the level of potassium in the brine tank low.

We recommend keeping the level of salt in the brine tank about half full for most households. Larger households can start out with more. Let the salt level drop down to the water level before adding more salt. Potassium should be kept as close to the water level as is practical to help prevent a “salt bridge”. Periodically you may experience a salt bridge. A salt bridge occurs when the salt forms a crust right at the water level in the brine tank. The salt remains suspended above the water and cannot make the brine solution required for the regeneration of the softener bed. If you do experience a salt bridge, simply tap a broom handle down in the salt to break up the bridge. Wait at least 1 hour, and then manually regenerate the softener.

Please refer to the Specifications and Limitations page in our manual.

Normally it is not necessary to clean the brine tank. In time, dirt and silt can build up in the brine tank and if you choose you can clean it out. Let the salt level drop down very low. The night before you clean, manually regenerate the softener. Disconnect the brine line and dump out the old salt, (Do not dump the old salt anywhere near living plants). Reconnect the brine line, add about (3) gallons of water, and add the new salt.

It is not necessary to change the control valve settings other than the ones described in the owner’s manual. Over the course of several months it is possible the display will not show the correct time of day due to power fluctuations. Reset the control to the correct time of day. If your feed water hardness changes, reset the control to the new hardness. Other settings are programmed at the factory for optimum efficiency and do not need to be changed.

The softening process does add some sodium or potassium to the conditioned water. The following chart shows approximately how much sodium or potassium is added to one quart of conditioned water based on the amount of feed water hardness. CHART IMAGE HERE!!!!! For comparison, (2) slices of white bread contain approximately 278 milligrams of sodium and (2) cups of milk contain approximately 226 milligrams of sodium. One large banana contains approximately 600 milligrams of potassium.

See the owner’s manual for instructions on bypassing the softener. You may need to bypass the softener for service or if you do not want your household water to pass through the softener. The instructions are also shown on the bypass valve. Make sure you depressurize the system before performing any service or removing the softener. See the “WARNING” in the owner’s manual.

It is not necessary to shut down the softener for periods of non-use equal to two-week to one-month vacations. If however, you are a temporary resident and leave for periods of four to six months, we recommend you shut the softener down. Put the softener in bypass and unplug it. When you return you will need to start the softener up. Make sure there are approximately (3) gallons of water in the brine tank, plug the softener in, and manually regenerate the softener.
