Changing the Fuse
** This section applies to the RF-3000LE Electrofusion Processor only. The Rionfuser LT Electrofu-
sion Processor has no external fuse that can be changed.
Important Notes
• The fuse protects the internal electronic circuitry. If the display lights up when power is
turned on, you DO NOT need to replace the fuse.
• This procedure should be performed in a "shop" environment, never a "field" environment.
• The most probable cause of fuse failure is a defective or inappropriately sized generator. If
you have a fuse problem, check your generator first.
Tools Required
• 1/8" Flat Blade Screwdriver
• 5 x 20mm, 250V, 2 Amp Slow Blow Fuse.
Use a Cooper Bussman Fuse Part Number BK1/S506-2-R or equivalent.
Procedure
1. Insert a screwdriver into the slot in the fuse holder cap. Press in slightly while turning count
er-clockwise, then remove the cap. The fuse should come out when the cap is removed.
2. Remove the old fuse and replace it with the new one.
3. Replace the fuse cap by pushing down and turning it clockwise.
