DNA Engine & DNA Engine Tetrad Operations Manual
Troubleshooting the DNA Engine Tetrad
The Tetrad is subject to the same problems with operations, protocols,
and reaction results as the DNA Engine (see chapter 11).
Maintaining the DNA Engine Tetrad
Cleaning
Clean the DNA Engine Tetrad according to the instructions in chapter 10
for cleaning the DNA Engine.
Changing the Fuses
Each quadrant of the Tetrad is protected by a fuse mounted in a plug on
the back panel of the base (fig. 12-6). Blown fuses may be replaced by any
15A fast-acting fuse (0.25” x 1.25”3AB or 3ABC).
To replace a fuse, first
unplug the power supply from the wall
. Twist the
fuse cap a quarter turn to the left and pull out the fuse plug. Replace the
blown fuse. Press the plug back into its socket, and twist it a quarter turn
to the right to seat it. The plug is spring-loaded, so firm pressure may be
required.

Warning:
The DNA Engine incorporates neutral fusing, which
means that live power may still be available inside the
unit even when a fuse has blown or been removed. Never
open the DNA Engine Tetrad base; you could receive a
serious electrical shock. Opening the base will also void
your warranties.
