FR Series Fuse Upgrade

Model:

 FR Series M1200/1400, 110V only

Serial #:

 M1200 prior to SN# AF12626

 Effective 4/28/97

 M1400 prior to SN# AH12657

Problem:

Original fuse (15A) rated too low.  Turn on inrush current causes fuse to
open.

Solution:

Replace the main (F1) fuse with a 20A 250V slow blow fuse.

Attention!: 

Since you will be working directly with the AC power line, 

great care should be

taken in all aspects of the installation

.  Power should be disconnected from the unit prior

to the installation process.
