1.2 To Open the Brute LX
To open the Brute LX for maintenance and servicing,
the upper and lower plastic panels are designed to 'pop'

covers the heat exchanger, and the lower panel which
holds the low voltage connections and covers the pump
and other lower components.
To remove these panels for further access into the
Brute LX, there are two screws that hold each panel in
place. Remove the 2 screws on the upper panel and slide
the upper metal panel up and out. For the lower panel,
remove the 2 screws and hinge the lower metal panel
downward.
The center panel containing the On/O Switch, Gauges,
and User Interface is not removable.
