LG Electronics LFC20740, LFC22740 Connecting the Water Line, Before YOU Begin, What YOU will Need

Page 29

CONNECTING THE WATER LINE

NOTE: Water line installation is needed when the Automatic Ice Maker and/or Water Dispenser features are available on your product.

BEFORE YOU BEGIN

This water line installation is not warranted by the refrigerator or icemaker manufacturer. Follow these instructions carefully to minimize the risk of expensive water damage.

Water hammer (water banging in the pipes) in house plumbing can cause damage to refrigerator parts and lead to water leakage or flooding. Call a qualified plumber to correct water hammer before installing the water supply line to the refrigerator.

To prevent burns and product damage, do not hook up the water line to the hot water line.

If you use your refrigerator before connecting the water line, make sure the icemaker power switch is in the O (off) position.

Do not install the icemaker tubing in areas where temperatures fall below freezing.

When using any electrical device (such as a power drill) during installation, be sure the device is double- insulated or grounded in a manner to prevent the hazard of electric shock, or is battery-powered.

All installations must be in accordance with local plumbing code requirements.

NOTE: Wear eye protection.

WHAT YOU WILL NEED

Copper Tubing, 1/4” outer diameter to connect the refrigerator to the water supply. Be sure both ends of the tubing are cut square.

To determine how much tubing you need: measure the distance from the water valve on the back of the refrigerator to the water supply pipe. Then add 8 feet

(2.4 m). Be sure there is sufficient extra tubing (about 8 feet [2.4 m] coiled into 3 turns of about 10 [25 cm] diameter) to allow the refrigerator to move out from the wall after installation.

Be sure that the kit you select allows at least 8 feet (2.4 m) as described above.

A cold water supply. The water pressure must be between 20 and 120 p.s.i. on models without a water filter and between 40 and 120 p.s.i. on models with a water filter.

Power drill.

1/2” or adjustable

wrench.

Straight- and Phillips-

blade screwdriver

Two 1/4” outer diameter

compression nuts and

2 ferrules (sleeves) to connect the copper tubing to the shutoff valve and the refrigerator water valve.

If your existing copper water line has a flared fitting at the end, you will need an adapter (available at plumbing supply stores) to

connect the water line to the refrigerator OR you can cut off the flared fitting with a tube cutter and then use a compression fitting.

Shutoff valve to connect to

the cold water line. The shutoff valve should have a water inlet with a minimum inside diameter of 5/32” at

the point of connection to the

COLD WATER LINE. Saddle-type shutoff valves are included in many water supply kits. Before purchasing, make sure a saddle-type valve complies with your local plumbing codes.

INSTALLATION INSTRUCTIONS

Install the shutoff valve on the nearest frequently used drinking water line.

1. SHUT OFF THE MAIN WATER SUPPLY

Turn on the nearest faucet to relieve the pressure on the line.

2. CHOOSE THE VALVE LOCATION

Choose a location for the valve

that is easily accessible. It is best to connect into the side of a

vertical water pipe. When it is necessary to connect into a horizontal water pipe, make the connection to the top or side, rather than at the bottom, to avoid

drawing off any sediment from the water pipe.

3. DRILL THE HOLE FOR THE VALVE

Drill a 1/4” hole in the water pipe (even if using a self- piercing valve) using a

sharp bit. Remove any burrs resulting from drilling the hole in the pipe. Take care not to allow water to drain

into the drill. Failure to drill a 1/4 hole may result in reduced ice production or smaller cubes.

LFC20740, LFC22740 specifications

LG Electronics has long been a leader in innovative home appliances, and its refrigerator offerings, particularly the LFC22740 and LFC20740 models, showcase their commitment to quality, functionality, and modern technology. These two refrigerator models are designed to meet the needs of contemporary households while adhering to the highest standards of energy efficiency and performance.

The LG LFC22740 is a 22 cubic feet, French door refrigerator that provides ample storage space without overwhelming a kitchen. One of its standout features is the Smart Cooling System, which employs advanced cooling technology to maintain optimal humidity and temperature levels. This system ensures that food stays fresh longer, thereby minimizing spoilage. The Linear Compressor, which is central to the Smart Cooling System, operates with fewer moving parts, leading to improved energy efficiency and reduced noise levels.

On the other hand, the LG LFC20740 offers similar quality but in a slightly smaller 20 cubic feet capacity. This model also utilizes the Smart Cooling System, ensuring that your groceries are kept at the perfect temperature, whether it’s a hot summer day or a chilly winter night. Both models feature a multi-air flow system that allows cold air to circulate throughout the refrigerator, maintaining consistent temperatures in every corner of the unit.

In terms of storage options, both LFC22740 and LFC20740 come equipped with adjustable shelving. This flexibility allows users to customize their storage space according to their needs, whether it’s for large party platters or day-to-day items. Additionally, the refrigerator compartments include humidity-controlled crispers, which are ideal for storing fruits and vegetables, ensuring they stay fresh and crisp longer.

For added convenience, both models feature an external ice and water dispenser. This not only provides instant access to chilled water and ice but also adds a touch of sophistication to the overall design.
