CONNECTING THE WATER SUPPLY wWARNING Connect to safe drinking water supply only. • The water pressure must be between 21 and 121 p.s.i. (1.5~8.5 kgf/cm2 ) on models without a water filter and between 43 and 121 p.s.i. (3~8.5 kgf/cm2) on models with a water filter. • If water pressure does not reach 21 psi (1.5kgf/cm2) or falls below, it is necessary to purchase a separate pressure pump for normal automatic icemaker and water dispensing operation. • It is recommended that the total length of the water feed tube does not exceed 26 ft. (8 m). • Install the water supply line where it will not be affected by heat. IMPORTANT: Read all directions thoroughly before you begin. • If operating the refrigerator before installing the water connection, turn the icemaker to the OFF position to prevent operation without water. • All installations must be in accordance with local plumbing code requirements. • Use copper tubing and check for leaks. • Install tubing only in areas where temperatures will remain above freezing. • It may take up to 24 hours for the icemaker to begin producing ice. Tools Required • Standard screwdriver • 7/16-in. and 1/2-in. open-end wrenches or two adjustable wrenches • 1/4-in. nut driver • 1/4-in. drill bit • Hand drill or electric drill (properly grounded) NOTE: Refrigerator dealers offer a kit with a 1/4-in. saddle-type shutoff valve, a union, and copper tubing. Before purchasing, make sure a saddletype valve complies with local plumbing codes. Do not use a piercing-type or 3/16-in. saddle valve which reduces water flow and clogs more easily. NOTE: The Commonwealth of Massachusetts Plumbing Code 248CMR shall be adhered to. Saddle valves are illegal and use is not permitted in Massachusetts. Consult with your licensed plumber. Cold Water Supply • The icemaker water valve contains a flow washer which is used as a water pressure regulator. • The icemaker needs to be connected to a cold water line with water pressure between 21~121 psi (1.5~8.5 kgf/cm2) on models without a water filter and between 43 and 121 p.s.i. (3~8.5kgf/cm2) on models with a water filter. 17
