Electrical Requirements

WARNING

Electrical Grounding Instructions --This refrigerator is equipped with athree-prong(grounding) plug for protection against possible shock hazards. If atwo-prongwall receptacle is encountered, contact a qualified electrician and have thetwo-prongwall receptacle replaced with a properly groundedthree-prongwall receptacle in accordance with the National Electrical Code.

Refrigerator is designed to operate on a separate 103 to 126 volt, 15 amp., 60 cycle line.

Do not under any circumstances cut or remove the round grounding prong from the plug. Refrigerator must be grounded at all times. Do not remove warning tag from power cord.

WARNING

Do not use a 2 prong adapter.

Do not use an extension cord.

Grounding Information

Standard color for ground wires is green or green with yellow striping. Ground wires are not to be used as conductors carrying current. Compressor, condenser fan motor, evaporator fan motor, defrost timer, temperature control, and ice maker are grounded through an individual wire attached to electrical component and another part of refrigerator. Ground wires should not be removed from individual components while servicing unless component is removed and replaced. It is extremely important to replace all grounds prior to completing service. When nib-headedscrew is used to complete grounding circuit, replace screw with a like screw.

Locate and predrill 1/4" holes in 2x4. Countersink 2x4 for bolt heads using a wood bit. See "Installation Specifications".

2.Remove 2x4 mounting board from top rear of refrigerator. Bolt 2x4 securely to wall studs with supplied bolts. If application does not have studs such as a framed wall mount to wall, not surface, using a minimum 1/4" diameter fasteners (not supplied). If cabinets are deeper than 24" mounting board must be shimmed and structurally secured to the 2 x 4 board. Longer bolts are required to shim mounting board.

3.To avoid water line damage, verify water line is secure so refrigerator does not run over water line. See "Installation Specifications" for water line location.

4.Repair any loose flooring in cutout.

5.Tape door and drawer shut with masking tape.

Before moving the refrigerator in place, confirm the finished dimensions, electrical and plumbing locations, and minimum door and drawer clearances are accurate.

6.Position refrigerator in front of cutout.

Sound Information

Normal Operating Sounds

This new refrigerator may be replacing a differently designed, less efficient or smaller refrigerator. Today’s refrigerators have new features and are more energy efficient. As a result, certain sounds may be unfamiliar. These sounds are normal and will soon become familiar. These sounds also indicate the refrigerator is operating and performing as designed.

Freezer and fresh food fan air rushes and whirs.

Sealed system (evaporator and heat exchanger) refrigerant flow gurgles, pops or sound like boiling water.

Defrost heater sizzles, hisses or pops.

Condenser fan air rushes and whirs.

Compressor has a high pitched hum or pulsating sound.

Ice cubes from ice maker drop into ice bucket.

Ice maker water valve hookup buzzes when ice maker fills with water. This occurs whether or not refrigerator is connected to water supply. If refrigerator is not connected to water supply, stop sound by raising ice maker arm tooff position.

Foam insulation is very energy efficient and has excellent insulating capabilities. However, foam insulation is not as sound absorbent as previously used fiberglass insulation.
