1.5 MANIFOLD PRES. TRANSDUCER INST.
The transducer is mounted in a temperature controlled environment in
the cabin area utilizing the 10-32 UNF-2B tapped threads. Install the
supplied transducer snubber (hex brass part) to the transducer using
a pipe thread sealant and tighten to prevent leakage. Fabricate an
aircraft grade hose assembly and connect between the snubber (1/8
female NPT) and engine manifold pressure port (see your engine
manual for this location and thread requirements).
Connect to the DPU harness as shown in
‘APPENDIX B: DPU P1 Connector Harness Fabrication’ using the
supplied terminals.
IMPORTANT NOTES:
DO NOT: remove or drill the snubber inner silver filter.
DO NOT: modify, connect to, or break off the small black
plastic hose nipples on the sensor body.
DO NOT: mount the transducer near extremely hot areas such
as heater ducts, etc.
DO NOT: mount the transducer where corrosive or conductive
fluids may contact it during operation or maintenance.
DO NOT: mount the transducer in the engine compartment.
DO NOT: mount the transducer lower than the engine manifold
access port, or accumulated fuel/oil in the hose will not run
back into the engine and may cause sluggish performance.
