Fuses
There are three (3) fuses associated with the Trinity Lx150-400 controller but only one (1) with the Lx800
controller. Check these fuses before replacing the controller or any other electrical component; if the fuse is
blown, it will prevent the protected device(s) from functioning.
To check, and if necessary replace, the fuses:
•
Remove all 120VAC power from the appliance. Be careful to check that the unit is not powered from more
than one source e.g. a UPS (uninterruptible power supply).
•
Remove the front cover.
•
On models Lx150-400 the control panel is located below the heat exchanger. Fuses "A" and "B" are
accessible by removing the spring-loaded knurled knob of their respective holders. Push the knob toward
the panel, and twist approximately 1/4 turn counter-clockwise.
•
To access Fuse "C", remove the two #10 pan-head Phillips screws and lift the top cover from the panel. The
auto blade type fuse is installed in an "inline" style fuse holder.
•
On model Lx800, the control panel is located above the heat exchanger toward the back of the unit. Fuse
"A" is accessible by removing the spring-loaded knurled knob from its holder. Push the knob toward the
panel, and twist approximately 1/4 turn counter-clockwise.
After inspecting and if necessary replacing fuses, replace the panel cover and front cover. Restore power to the
appliance and confirm proper operation.
Only replace fuses with identical parts, see Figures 14-1(a) and (b). Failure to follow this
warning may result in component failure, fire, property damage, serious injury or death.
