Directions for the Coleman Thermoelectric Cooler

The Coleman Thermoelectric Cooler has no moving parts and does not require Freon refrigerant. Thermoelectric coolers are heat pumps that use electrical current and a principle called the Peltier effect to remove heat from the interior of the cooler. Though not as efficient as standard compressed gas refrigerators, thermoelectric units have the advantage of light weight and portability and are an alternative to ice chests for camping and outings. The Coleman Thermoelectric Cooler Model 5644 has a 40-quart capacity and cools contents to 40 degrees below the outside ambient temperature. Power can be supplied by a 12-volt DC power source or plugging the optional adapter into a standard outlet. The Model 5644 is 21.75 inches high, 15 inches wide and 17.125 inches deep and weighs 17 pounds.

Instructions

    • 1

      Connect the cooler to the cigarette lighter or 12-volt power outlet of a vehicle with the engine running, to a 12-volt battery connected to a charger or to the optional Coleman DC power supply adapter plugged into a standard household outlet.

    • 2

      Pre-chill items in your home refrigerator for faster, more efficient cooling in the thermoelectric cooler.

    • 3

      Place ice substitutes such as sealed reusable cold packs in the cooler to speed up cooling. Do not put real ice in the cooler.

    • 4

      Allow at least three hours for an empty cooler to cool down to 40 degrees below the outside temperature. A cooler stocked with warm items that have not been pre-chilled will take longer to cool.

    • 5

      Open vehicle windows slightly to provide ventilation if the cooler is running in a parked car, because thermoelectric coolers generate heat.
