Meter Installation in 4848 Reactor
Controller
1. Unplug the power cord of the 4848 Controller.
Remove the (2) screws located on the top/front
cover at the rear corners of the controller. Gen-
tly lift the cover forward, which is hinged at the
bottom, taking care not to apply tension on any
internal wiring.
2. If applicable, remove and discard the black hole
plug on the sloped front panel above the “PRES-
SURE” or “TEMPERATURE” text. This can be
done by pinching the clasps on the back of the
plug from the inside of the front plate. Place
“MOTOR OUTPUT” label over existing text.
3. Insert the MTM module (2084E) through the
panel cutout, from outside in, making sure the
rubber gasket is on the outside of the controller
front panel. (If wires are preinstalled, remove the
terminal connector by releasing the tabs on the
sides of the module and gently pulling the termi-
nal connector off. Reference photos below.) Slide
the white mounting bracket onto the module with
the mounting screws pointing towards the front
panel. Slide the mounting bracket forward until
it touches the controller panel. The clasps on the
mounting bracket should align with the groves
on the module. Gently tighten the screws until
the module is held into place. (If removed, reat-
tach the terminal connector.)
