Superb rendition. Drawings (schematics) complete and unabridged. I do a great deal of vintage audio restoration. Documentation is essential for successful repairs. I have found sources over the years that offer good documentation, but rarely all that is necessary. Owner's Manuals has filled that void with complete and legible documentation. They have narrowed my "favorites" to a more manageable collection. This Denon manual in particular contained the latest revisions level, and offered alterations favorable to updating the item. The Illustrated Parts Breakdown (IPB) was well enough detailed to simplify part symbols and physical locations. You will not be disappointed!

2. DEFROSTING (1) No defrosting operation is necessary No defrosting operation is necessary. As this machine is so designed that a built-in evaporator cools air and a fan circulates cooled air, neither the freezer nor the refrigerator is frosted, though the evaporator is frosted. The frosted evaporator is defrosted automatically due to the function of defrosting timer and heater, requiring no defrosting operation.

(2) Where is melted ice brought 1. Melted ice is brought into the evaporating pan at the bottom of the set and is evaporated here by the heat of sub condenser. 2. Be sure that the evaporating pan is inserted correctly and is level.
(3) The following circuit diagrams in the table show automatic defrosting function of the refrigerator with timer and defrost thermostat. Operation 1. Cooling (Normal) Electric diagram
Defrost thermostat ON Compressor running Timer motor running Thermostat Timer contact
Description The integration timer integrates running time of the compressor. When it reaches 10 hours 50 min. at 50Hz, the timer contact is changed to start defrosting.
