OPERATION
Figure 19
A gurgling sound or running water
sound may be evident as the refri-
gerant circulates through the
tubing.
In Model 590, the ice dispenser
valve within the refrigerator
door
snaps closed 5 seconds after
either the water or ice dispenser
switch is released.
During the icemaker cycle you
may
hear the sound of ice
dropping
into
the container or of the solenoid
valve while refilling the icemaker
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 defrost
water pan.
While the compressors are in
operation a slight
hum
may
be
evident. During the startup and
shutdown of the compressor,
some vibration may occur lasting
only a few seconds.
MAINTENANCE AND
CLEANING
!ACAUTION I
We
recommend for main-
tenance
and
cleaning, that the
circuit breaker
or
master
power
switch
if
applicable to the re-
frigerator
be
shut
off
and
pro-
tective gloves (when cleaning
the condenser) be worn.
CONDENSER:To
insure
proper
performance,
the cleaning of your
unit's
condenser
is required. This
should be
performed
every 3 to6
months
under normal use. To
clean, remove grille. See page
14.

Certain noises may be evident with
the normal operation of the unit.
Surrounding acoustics like walls,
floors and cabinets may affect the
sound level of your unit.
MASTER POWER
SWITCH
MODEL 590
The Model 590 features a Master
Power Switch. This switch, which
is
located behind the top grille, will
turn off all electrical power to the
equipment. See Figure 19. This
eliminates having to shut power off
at the circuit breaker or having to
pull the power plug from the wall
receptacle. This switch
can
be
used for either shutting
down
the
equipment for servicing or during
extended vacations.
In
order to access this switch, the
front inner grille panel assembly
must be first removed (refer to
panellized grille removal instruc-
tions on Page 14, Figure 23).
during
each off cycle of the refrig-
erator. The freezer section is con-
trolled
by
a timer which defrosts as
needed.

For your convenience your Sub-
Zero unit
is
equipped
with an auto-
matic defrost system. The
refrigerator section will defrost
The level of ice in the ice containers
is
controlled by an ice level arm.
When the containers are filled with
ice the ice level arm senses the
level and shuts
down
the icemaker
As ice
is
used, the level
drops
and
the level arm signals the icemaker
to restore ice production.
These
icemakers
are designed
to
produce
an
adequate
supply of
ice
for normal family
consumption.
The length of time
between
ice
harvest
cycles
will
vary depending on load condi·
tions,
door
openings and ambient
room temperatures. On the
average, you can expect a harvest
of ice every 2 hours.
If
ice
is
not used regularly
it
will
tend to fuse together
To
avoid this,
empty the ice container periodically.
