Fuses
There are three (3) fuses associated with the Trinity Lx150-400 controller but only one (1) with the Lx500-800
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 boiler. 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 models Lx500-800, 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
boiler and confirm proper operation.
Only replace fuses with identical parts, see Figures 17-1(a) and (b). Failure to follow
this warning may result in component failure, fire, property damage, serious injury or
death.
