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. Gently 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 Blank Plate located at
the Primary Temperature position on the front panel. This
can be done by removing the (2) 6-32 keps nuts and washers
from the plate located on the inside of the front panel.
3. If replacing an existing meter, make a note of where the
wires are installed on the existing primary temperature
meter. The pin numbers are printed on the back of the
meter itself. They should match the Pin Out table on the
next page. Using tape to designate each wire, record the
pin number each wire is attached to. If not replacing an
existing meter move on to step 6.
4. Using a Phillips screwdriver, remove the wires from the back of the primary temperature
meter.
5. Using a Phillips screwdriver, remove the two screws on the top and bottom mounting
brackets. Pull the meter out.
6. Insert the new meter through the panel cutout, from
outside in, making sure the rubber gasket is on the
outside of the controller front panel. Slide the
mounting brackets onto the meter 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
brackets should align with the grooves on the meter.
Gently tighten the screws until the meter is held
into place.
7. If applicable, connect the free wires (disconnected
in step 3) to the new meter. Check the positions
carefully. If a wiring kit was included the wires may be attached to the Primary Temperature
Controller. Reference the Pin Out Table for proper wiring connections.

Final Steps:
Close the controller and replace the two screws on the top plate. Plug the 4848 Controller back in
and turn it on. The display should show room temperature with the thermocouple connected. It is
useful to check that the settings on the display are set correctly. Check these against the Factory
Default Settings.
