Instrumentation Wiring Harness Connection

Exhaust System Hoses/Tubes Connection

1. Exhaust hoses/tubes must be connected to exhaust elbows so that they do not restrict

the flow of discharge water from the elbow. If hoses/tubes are connected incorrectly, a
hot spot in the hose/tube can occur, and can eventually burn through.

2. Exhaust hoses/tubes should be secured at each connection with at least 2 hose clamps.
