Note - If installing an additional pressure gauge, ensure that the correct Vacuum
or Pressure Transducer Modules are installed on the Interface Module, and
that the Interface Module has been programmed to recognize the new gauge.
1. With your hand, turn the bezel counter-clockwise about
bezel, glass, gasket, and mask ring. This requires a fair amount of initial force.
2. Gently slide the gauge out of its housing.
3. Gently pull the scaleplate programming tab out from under the connector on the
printed circuit board.
4. Remove the scaleplate by allowing the gauge pointer to pass through the cut on
the scaleplate.
1. Attach the scaleplate to the gauge as shown in Figure 4-2.
2. Referring to Figure 4-3, insert the gauge body into the housing. Ensure the con-
nector extends through the rear of the housing. The three round notches around
the edge of the printed circuit board fit over the round guides on the inside of the
housing. The gauge is correctly inserted when the two round notches in the front
of the gauge fit over the two round guides on the inside of the housing and the
connector extends slightly out the rear of the housing.
3. Hold the gauge and housing face up. Line up the hole in the finger of the mask
ring over the warning LED in the gauge body and place the mask ring down
over the scaleplate. When the mask ring is correctly installed, the two round
notches on the outside will mate with the two guides on the inside of the housing.
4.
Center the gasket over the mask ring.
5. Center the glass faceplate over the gasket.
6. Line up the tab on the back of the bezel with the cut-out in the housing, then
twist the bezel
turn clockwise until it clicks into place.
