Installing a new front panel assembly:
1) Remove the protective backing from the bottom side only of the new membrane panel.
2) Hold the upper weldment upright against a well-lit backdrop to assist in aligning the
membrane panel with the cutouts in the upper weldment.
3) Handle the ribbon cable carefully to prevent any damage to the silver contact area.
Carefully slide the ribbon cable out through the slot in the upper weldment.
4) Be very careful when aligning the membrane panel - once it is applied, it cannot be
removed without destroying it. Carefully align the membrane panel with the upper weldment,
making sure the cutout for the rotary switch is centered over the well in the upper weldment
and that all display windows align over the corresponding openings. Press the membrane
panel into place making sure the adhesive is well seated in all places.
5) Turn the ventilator over. Reconnect the ribbon cable (see instructions on page 8-86). Be
careful not to scratch the ribbon cable.
6) Replace the power board (see instructions on page 8-105).
7) Replace the alarm sounder , (see instructions on page 8-55 ).
8) Reconnect the 2-wire fan connector, 4-wire rotary switch connector, and 2-wire sounder
connectors to the power board. These are keyed connectors and can only be installed in
one direction. They will snap into place when properly connected.
9) Reconnect the flexible tubes to the Flow Xducer and Exh Valve fittings on the side panel of
ventilator following the internal flexible tube routing tables, instructions and diagrams on
page 8-33 . Inspect all flexible tubes for tears at the connecting ends and replace worn or
damaged tubes if necessary.
NOTE
Tubing Configurations - If tubing is worn or damaged and needs to be replaced, consult the
tables and instructions in Internal Flexible Tubing beginning on page 8-33 for tubing diameters,
lengths and routing diagrams.
