PRO 48 Use & Care
Ice Maker Operation
The ice maker in the PRO 48 is fully automatic and has
been tested at the Sub-Zero factory. To turn the ice maker
on or off, press the ICE MAKER key pad on the control
panel. When the ice maker is on, it will be operating any
time the drawer is closed.
IMPORTANT NOTE: A reverse osmosis system can be
used, provided there is constant water pressure of 20 psi
(1.4 bar) to 120 psi (8.3 bar) supplied to the unit at all
times. In this application, the water filtration system
must be bypassed. Refer to water filter bypass mode on
the previous page.
ICE PRODUCTION
The ice maker is designed to produce enough ice for
normal family use. The timing of ice making cycles will
vary depending on load conditions, door and drawer
openings and room temperature. On average, you can
expect a cycle of ice (eight cubes per cycle) every two
hours.
For extra ice capacity, remove the ice bucket with the ice
maker system on and allow the drawer to fill with ice.
IMPORTANT NOTE: Removing the ice bucket will not
increase the rate of ice production.
If ice is not used on a regular basis it tends to fuse
together. To avoid this, empty the ice bucket periodically
allowing it to replenish with a fresh supply.

DOOR AND DRAWER CLOSING
The PRO 48 refrigerator and freezer door hinges have an
auto-close system that allows doors to finish closing auto-
matically. As you close the door, the built-in cam takes
over to close the door the final 15°. A built-in door stop
allows both doors to stay open at approximately 120°.
For corner applications, an optional door stop kit is avail-
able that limits the door opening to 0°. Optional acces-
sories are available through your authorized Sub-Zero
dealer. To obtain local dealer information, visit the find a
showroom section of our website, subzero.com.
The PRO 48 refrigerator and freezer drawers have an
auto-close system that allows drawers to finish closing
automatically. The drawers have an automatic stop built in
at full extension.
