OPERATION

Water Filtration System

The water ltration system of Sub-Zero PRO 48 models supplies ltered water to the ice maker to produce greattasting ice.

IMPORTANT NOTE: When using the water ltration system

for the rst time and after lter replacement, it is necessary to clear any air from the system and allow the lter to assist in cleaning the water lines. Discard the rst two full containers of ice.

If the water ltration system will not be utilized, it can be placed in water lter bypass mode by removing the lter.

The lter is rated for 750 gallons

(2839 L) or one year,
