Refrigerator Storage
GLASS SHELVES
To remove or adjust a glass shelf, tilt up, then lift up and out.
To reposition, insert shelf in the tracks along the back wall,
then lower the front until it locks into position. Refer to the
illustration below.
IMPORTANT NOTE: Use care when handling glass shelves to
prevent breakage or scratching the interior.
CAUTION
Glass shelves should warm to room temperature before
immersing in warm water.
SLIDE-OUT BINS
Integrated rails mounted below the glass shelves allow
slide-out bins to be positioned in a variety of locations. To
remove or adjust a slide-out bin, pull the handle of the bin
forward until it stops, lift up and out of the rails. Refer to the
illustration below.
Keeping Food At Its Best
This Sub-Zero features a unique dual refrigeration system
to keep food fresher longer. Three separate controls allow
the refrigerator, refrigerator drawers and freezer to be set at
different temperatures.
With the Sub-Zero dual refrigeration system, individual
refrigerator and freezer systems have been designed to
maintain accurate, consistent temperatures and proper
humidity levels for longer food life expectancy. Dual refrig-
eration eliminates transfer of fresh food odors to frozen
food and ice and does not freeze the moisture out of the
air in the fresh food section.

both sides of the drawer front and pull out. To reinstall, raise
the front of the drawer and place onto drawer slide tracks.

The water ltration system of Sub-Zero PRO 48 models

tasting 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 con-
tainers 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,
whichever comes rst. When the lter needs to be replaced,
‘REPLACE FILTER’ will be visible in the external display.
Replacement Sub-Zero water lters can be ordered online
