Abstract: In a door bearing, a bearing arm having a bearing bore is fastened to a stationary construction, such as a door frame. A bearing pin which is axially displaceable in the door engages the bearing bore. In order to permit quick and simple release of the bearing in a minimum amount of space, an open recess is provided within the door. Through this open recess, the bearing pin can be reached manually or by means of a tool in order to withdraw it from the bearing bore.

Abstract: In order to permit a motor-compressor unit to be connected with the coolant circuit of a cooling device without interference from the walls of a compartment provided in the cooling device for housing the motor-compressor unit and to secure the motor-compressor unit in the compartment, the motor-compressor unit is placed at least partially outside the compartment and is pushed into the compartment and secured therein only after its coolant conduits have been connected with the coolant circuit and the electrical connections have been made. For this purpose, a mounting plate is temporarily installed in the compartment and the motor-compressor unit is loosely placed on it. After the connections have been made, the motor-compressor unit is pushed into the compartment on the mounting plate and then the mounting plate is removed. The tongues on rails secured to the motor-compressor unit are then screwed into the housing of the cooling device at the entrance to the compartment.
