This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

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.

The timer contact is changed to start defrosting, the timer motor stops, and power is supplied to the defrost heater. It takes about 20 to 30 min. to defrost. The defrost time will vary depending upon the amount of frost.
