Assembly of Regulator Diode
(D5801)
Step 1 Apply grease to the heatsink unit C.
Step 2 Mount the regulator diode (D5801) on SMPS P.C.B.
Caution: Ensure pins of the regulator diode (D5801) are
properly seated and soldered on SMPS P.C.B.
Step 3 Fix and screw the regulator diode (D5801) to the heat-
sink unit C.
Caution: Ensure the regulator diode (D5801) is tightly
screwed to the heatsink unit C.
Step 4 Solder pins of the regulator diode (D5801) on the solder
side of SMPS P.C.B.

Diode (D5802)
9.24.1.
Disassembly of Regulator Diode
(D5802)
• Follow (Step 1) to (Step 3) of Item 9.3.
• Follow (Step 1) to (Step 10) of Item 9.6.
• Follow (Step 11) to (Step 13) of Item 9.12.
• Follow (Step 1) to (Step 7) of Item 9.19.
Step 1 Desolder pins of the regulator diode (D5802) on the sol-
der side of SMPS P.C.B.
Step 2 Remove 1 screw from the regulator diode (D5802).
Step 3 Remove the regulator diode (D5802) from the SMPS
P.C.B.
Caution: Handle the heatsink unit C with caution due to its
high temperature after prolonged use. Touching it may
lead to injuries.
Note: Refer to the diagrams of SMPS P.C.B. (Item 18.5) for
location of the electrical components.
