Energy Saving tips
• Let hot foods cool to room temperature before placing in the unit. Overloading the unit forces the
compressor to run longer.
• Be sure to wrap foods properly, and wipe containers dry before placing them in the unit. This cuts
down on frost build up inside the unit.
• Unit wire rack should not be lined with aluminum foil, wax paper or paper towels. Liners interfere
with cold air circulation, making the unit less efficient.
• Organize and label food to reduce door openings and extended searches. remove as many
items as needed at one time, and close the door as soon as possible.
