Mounting the Filter System

Stop the flow of cold water to the refrigerator and distribute the water from the refrigerator door as long as the water flow stops to free the pressure inside the pipes before beginning installation. Keep a tray or towel under water to hold excess water after the pipe is cut out.

Choose a place under the sink, near the refrigerator, and basement where the filter is to be mounted. When the filter gathers is mounted by the side of a wall near the drawers, take out the drawers.

The cabinet wall can be very thin to support the filter assembly. We suggest using a 3″ x 3″ x 1/2″ wood block by the side of the cabinet to permit the screw to enter through the cabinet and to the wood block.

The system permits the filter assembly to support well. Apply the filter head assembly as a template and drill two 1/4-inch gaps in the side wall. Keep the block of wood behind these two holes and drill 2 1/8 inch holes into the block.

Apply two screws given to mount the filter assembly head to the inside wall and for the block of wood.

Filter water must be set in a vertical position. Apply mounting bracket to indicate a template to refer screw locations. Mount filter head in indicating the location of the used screws.

Cutting or Disconnecting the Tubing

Select a seven to eight-foot coil of plastic tubing between the refrigerator and the outlet of the filter.

Measure the length of plastic tubing to add to the inlet as well as the outlet of the filter.

Take a utility knife to cut the tube cleanly. Keep a minimum of two inches of tubing after shutting off the valve so that the tubing must be re-cut at a later time.

Connecting the Tubing and Fittings

NOTE: If water does not flush through the existing water dispenser, add T- Flush valve first and connect the outlet of the filter just like step 3A. Look at Page 1 to see T-Flush valve diagram.

Connect the Intel. Assemble adjusts as a present, by an entering tube 5/8 inch to inlet fitting of the head.

Connect the filter like as step (3A).

Installing the Cartridge

Catch the cartridge from the beneath if you like to change or install the cartridge. Be careful not to scrape knuckles on the bracket while locking the cartridge to the place.

Line up the arrows of the cartridges along with the unlocked padlock on the head. Enter the cartridge and then move the arrow to lock the padlock. Details are shown in Diagrams R2 and R3.

Putting the Filter into Operation

NOTE: In a drinking water cartridge, there is a carbon fine. As there is carbon fine in the ice maker, discard the ice. Start the water supply to fill the filter with water. Notice if have any leaks. When there is a leak, see Troubleshooting.

  • Flush the filter up to ten minutes by water dispenser or when the appliance is decorated with only an ice maker, by the T-Valve and abandon water.

User Review On Culligan US-EZ 1 Water Filter

Inexpensive and works

We have purchased the filter to eliminate chlorine taste from the water of the city; it functions amazingly. The faucet is an excellent chrome like finish, and it can flow quite well.

Culligan US 1 EZ-Change Under-Sink Drinking Water Filtration System

Installation needs to know some ways how. If you have no other hole in the tank, you need a hole.

The whole size is 1.5  inch. If you got a sink just like me, try to get a bi-metal hole saw. If you like to get water from the filtration system, you have to need an adapter which you need to install the cold water valve.

People who have threaded pipes this will do perfectly for them.

I had gone to the hardware store and bought a new water valve that has outlet 1/4 inch water line. Thrown away the adapter. I would suggest this new valve, and you can turn off the supply of water system very simply if you need to do so.

At the time of buying the new valve, do not forget to purchase the compression and little insert ring for 1/4   inch water line.

The tricky part is to remove the old compression ring. There are some special tools to do so, the elbow and pliers can do it.

Long-Term Benefits

My wife gets pure drinking water for the whole day. She is wise enough so she did not buy bottled water but she enjoys the taste of clean and pure water.

She used the Britta Pitcher for the last four years and left the black junk from water, always is the way and added eight dollar filter for the last two months. I installed it on the edge of the sink so that the cup may sit well on the counter.

We installed it three months ago, and we are happy now to have safe water. The filter is working well and has not matter of funny taste. It has got five instead of four stars for faucet can be heavier duty.

I have bought the cheapest one from the shops, so you will obtain what you pay for. It may break anytime soon, and I suggest it to anyone.
