Filters
The FreshSaver filter is located in the fresh food drawer and
will last for 1 year. Some models are equipped with a
FreshSaver FILTER LED. After a 1-year refrigerator
operation time the FreshSaver filter LED will illuminate as a
reminder for the owner to change the filter. The LED can be
readjusted by pressing and holding the HOLD 3 SECS key for
3 seconds. The LED will flash while the key is pressed, it will
remain illuminated for 3 seconds after the key has been
released and turned off.
Some models are equipped with a water filter that is located
in the upper corner of the right side of the cooler
compartment. The filters are designed to be used for up to 18
hours of valve open time or 1 year of clock time.
When 90% of the filter time has passed (valve open time or
clock time, whichever comes first) the main control board will
illuminate the filter reminder LED (amber). When 100% of the
filter time has passed, the main control board will illuminate
the filter reminder LED (Red).
Hinge and Door Closing System
The hinge clamps are not adjustable in the cabinet. The
cooler door can be adjusted up and down using the hinge
adjustment pin (located on the bottom hinge of the cooler
door).
This refrigerator is equipped with an open / close door detail.
This detail consists of a loaded spring arm located in the
lower part of the cabinet for each door. The arm stops the
door when it is partially open and automatically closes the
door when it is almost closed.
IMPORTANT: The refrigerator rollers must be properly adjusted
for proper door closure. When the wheels are adjusted correctly,
the door should close easily when it opens approximately 45
degrees (half way).
Air Flow (Cabinet Interior)
AIR FLOW
The freezer cabinet is designed so that air is carried inside the lower part
of the air tunnel and through the evaporator when the evaporator fan is
operating. The cold air is then pushed out towards the top of the freezer.
The cooler compartment receives cool air through an electronic shock
absorber that is located in the upper rear of the cooler between the freezer
cabinet and the cooler cabinet. The cushion is controlled by the main
control board and when it is opened, it allows the cold air from the freezer
air tunnel to move inside the cooler's air tower. The cold air tower of the
cooler contains a cooling fan that draws cold air from the freezer (through
the damper) into the air tower. The air tower directs cool air through the
top of the cooler cabinet to two exits. The air tower also directs cool air
down the back of the wall of the cooler cabinet. The cold air draws the air
out of the tower through fans in the tower.
The air returns from the cooler cabinet to the freezer cabinet through an
upright located on the left side of the fresh food drawer.
