Viking FDFB5363 Installation Instructions - Page 37

General Information Water Supply Requirements WARNING To avoid serious illness or death, DO NOT use unit where water is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts. The contaminants or other substances removed or reduced by this water treatment system are not necessarily in your water. Use only 1/4" (6 mm) copper tubing for water line. DO NOT install copper tubing in area where temperatures drop below 35˚ F (1.7˚ C). Before attaching copper tubing to the unit, flush at least 2 quarts (1.9 L) of water through the copper tubing and into a bucket to remove any particles in the water line. • Viking Range, LLC is not responsible for property damage due to improper installation or water connection. • Connect 1/4" (6 mm) flexible copper tubing to household plumbing in compliance with local codes and ordinances. • Length of copper tubing must reach from water supply connection to the unit connection with an additional length to facilitate moving the unit out of enclosure for cleaning or service. Tubing should be soft instead of rigid and ends should be free of burrs. • Copper tubing route must be above 35˚ F (1.7˚ C) to prevent water line from freezing. • DO NOT use plastic water lines from the household plumbing to the water inlet valve connection on the refrigeration unit. • DO NOT use the self-piercing feature of a saddle valve. The hole made by the piercing lance is too small for the water flow rate required by the ice maker. • If saddle valve is not used, place a separate shut-off valve in an easily accessible location between water supply and the unit. DO NOT install shut-off valve behind the unit. • The installation of Viking units with a reverse osmosis system is acceptable as long as the water pressure remains within the allowable PSI as stated below. It is important to note that with many reverse osmosis systems, the pressure starts off high, but then it decreases as the water level of the reverse osmosis storage area drops. This must be considered when checking the water pressure coming into the unit. • Connect a vertical or horizontal 1/2" (1.2 cm) to 1-1/4" (3.2 cm) COLD water line near water area. • Run water line through the floor, back, or side wall. Tubing should lay flat on floor underneath the unit. Clamp tubing to wall or floor. • Water pressure must be greater than 20 psi and less than 120 psi on non-dispensers and greater than 35 psi and less than 120 psi on dispensers. 37
