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. • If a reverse osmosis water filtration system is connected to your cold water supply, This water line installation is not warranted by the refrigerator or icemaker manufacturer. Follow next instructions carefully to minimize the risk of expensive water damage. • If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 40 to 60 psi (2.8 kgf/cm2 ~ 4.2 kgf/cm2, less than 2.0~3.0 sec to fill a cup of 7oz capacity). • If the water pressure from the reverse osmosis system is less than 21 psi (1.5 kgf/cm2, more than 4.0sec to fill a cup of 7oz capacity): • Check to see whether the sediment filter in the reverse osmosis system is blocked. Replace the filter if necessary. • Allow the storage tank on the reverse osmosis system to refill after heavy usage. • If the issue about water pressure from reverse osmosis remains, call a licensed, qualified plumber. 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. saddletype shutoff valve, a union, and copper tubing. Before purchasing, make sure a saddle-type 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.
