3.6 UBER BOILER LOADCELL REPLACEMENT
Remove the Display Board Bracket, as described previously.
3.6.1 Loadcell Attachment to Tile:
Ensure the loadcell has the connector crimped on. Place 2 x O-rings on the 2 x M5 screws
and place 2 x M6 washers between the load cell and the mounting plate. Tighten the 2 x M5
screws into the threaded holes on the loadcell, as shown below. Do not over-tighten the
screws or the O-rings will squash out the side. The O-rings are needed to ensure a
watertight seal. The washers are needed to to provide operational clearance between the
load cell and mounting plate. Note the arrow mark on the loadcell showing which way the
load is to be applied. Ensure visually that the holes are centrally in line with the 32mm
diameter hole in the driptray.
3.6.2 Fixing Support Platform to Loadcell:
Ensure the platform support is fully sanded and that M4 rivet nuts are attached. Pass the 2 x
M5 screws through the top and through the plastic spacers. Now place it on the loadcell and
loosely begin to screw them in, locating the threaded holes in the loadcell. Be careful not to
press down hard with the screwdriver and overload the loadcell which should only be
subjected to 5kg of force or it will break. When it is level and ready to be tightened, place the
4 spacers around the sides and tighten it fully. Again be careful not to press down too hard.
The spacers will keep it central. Any suitable spacers can be used to centre the platform.
