Extension Cords
Because electrofusion fittings produce a high amperage draw, the use of an extension cord is not encouraged. In the event
such usage is necessary, the following lengths and wire gauges are recommended:
Cord Length
Wire Gauge
Less than 25 feet
12/3
Less than 50 feet
10/3
Less than 100 feet
8/3
Extension cords should not be used when fusing multiple fittings at the same time
.
Calibration Warnings
** This section applies to the
RF-3000LE Electrofusion Processor
only.
Rionfuser™ Electrofusion Processors
are programmed to provide operators plenty of time to schedule a calibration. However, if the
RF-3000LE Electrofusion Processor
reaches its calibration due date, it will stop fusing until it has been calibrated.
When the calibration due date is within 90 days or less, the processor will display reminders whenever the machine is powered
on. The calibration reminder will look similar to this:
90 DAY REMINDER
Calibration Due On
mm/dd/yyy
PRESS START
The processor will countdown the number of days until calibration is due. The text mm/dd/yyyy shows the month, day and year
that the calibration is due.
To avoid being locked out of the processor, Watts recommends scheduling a calibration as soon as it starts to
display this reminder message.
On the date that calibration is due, the processor will display, "Error 113: Calibration Required", and stop fusing until it is
calibrated.
When the RF-3000LE Electrofusion Processor displays Error 113, it will not fuse until it has been calibrated.
To schedule a calibration, please see page 2 for instructions and contact information.
General Maintenance
Changing the Fuse
** This section applies to the RF-3000LE Electrofusion Processor only. The Rionfuser™ LT Electrofusion 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 counterclockwise, 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.
