Door Closing
Models 601R, 601RG, 601F,
561, 642, 632, 680 and 690
Your refrigerator and freezer
doors have spring-loaded closure
mechanisms. As the doors are
closed, the door closure engages
to help close and seal the doors.
A 90° door stop is available
through your Sub-Zero dealer.
Door and Drawer Closing
Models 611, 611G, 650 and
650G
Your refrigerator door has a door
closing cam to help in closing
the door. With the door opened
to about 120° the cam will hold
in the open position if the door is
stopped. As you close the door,
the cam will take over at about
15° to help close the door.
Your freezer drawer has a self-
closing mechanism. The incline,
built into roller assemblies on
the drawer, uses gravity to assist
in closing the drawer.
If your Series 600 unit is
positioned in a corner, you may
want to install an optional door
stop kit which limits door
opening to 90°. This door stop is
provided with each Model 611,
611G, 650 and 650G, and is
shipped in a plastic bag in the
grille area.
Condenser Fan Motor
Operation
All 600 Series models have a fan
behind the grille to cool the
compressor area. This fan runs
with either compressor.
Automatic Defrost
For convenience, your Sub-Zero
unit is equipped with an
automatic defrost system. The
refrigerator section will defrost
during each off cycle of the
refrigerator compressor. The
freezer section is controlled by
an energy-saving Adaptive
Defrost system, which defrosts
as needed. (Not available on the
Model 561).
Sounds
You may hear some noises in
the normal operation of the unit.
Surrounding acoustics like
walls, floors and cabinets may
affect the sound of your unit.
For example, a gurgling or
running water sound is probably
refrigerant circulating through
the tubing. In Models 680 and
690, the ice dispenser valve
inside the refrigerator door
snaps closed five seconds after
either the water or ice dispenser
key is released.
During the ice maker cycle you
may hear the sound of ice
dropping into the container or
the solenoid valve operating
while refilling the ice maker
with water. During the freezer
defrost you may hear crackling
and/or sizzling as the heat from
the defrost element clears the
frost from the freezer coil and
water runs into the water pan.
While the compressors are in
operation you may hear a slight
hum. During the startup and
shutdown of the compressor,
you may feel vibration for a
few seconds.
Some of these noises may be
enhanced when the units door(s)
are open.
