Introduction
2001 SxS Energy models are being introduced in response to
the requirements of more energy-efficient refrigerators by mid-
2001, along with improvements in features and operation.
The
primary differences in this cooling system are the defrosting
adaptable system (watch Pub # 31-9062), control board,
software, and systems control that operate regardless in the
sections of the cooler and freezer. The new high-efficiency
control system has the ability of cycling components and
adjusting the fan speeds as required, to maintain the
temperature adjustment ranges in the cooler and freezer
sections.
The feedback systems are digital inputs and relay
outputs. The sensors (thermistors) are used to measure the
temperature with communication to the main board, which
controls the components of the
unity.
The refrigerator has key controls to give inputs to the
microprocessor.
The cooler and freezer controls are of the
temperature control point type and have settings of 0-9 with 9
being the coldest possible temperature. The new NON-
CLEAN condenser is repairable from the back and is designed
to
prevent the customer from having to
clean the condenser in conditional normal use.
The sealed operation system and the compressor are working
in the same way as the previous models, with some minor
changes.
The collateral models Profile Performance and Arctica are
the affected models.
These models are available with cold
water through the door and ice dispenser, and a water filter
detail that can be filled.
In models that require an ice
machine, the new electronic ice machine model (see Pub. #
31.09063) has been or can be installed.
The freezer has built-in grills, a spill-proof grill that pulls out,
an Easy Space grill, deep door grills, based on the model.
The
chiller section has a Baking Soda holder, a fruit and vegetable
drawer, drawer dividers, and a moisture-adjustable drawer
and a convertible meat drawer.
The new high-efficiency refrigerator is a combination of the
most efficient refrigeration systems and the most desirable
customer details available.
