Refrigeration piece of the working condition is a side of the cooling side of the heat, work must be given to the heat surface good heat dissipation, is strictly prohibited in the absence of heat dissipation under power for more than 2 seconds, resulting in overheating burned buyers at their own risk!

Always apply thermally conductive silicone grease when installing a heat sink.

The lettered side is the cold side and the unlettered side is the hot side.

Please note: This refrigeration unit has a large power, change the water dispenser. Car refrigerator do not buy this cooling pads!!!!
