Introduction

The problem that is identified below does not have a known permanent solution. Until a permanent solution is identified, use the solution that is provided below.

Problem

Orientation of the ladder clip and sensor angle of 38° instead of 45° is incorrect and can cause supply wire G828-WH(White)to break from the connector.

Solution

If fault is found perform visual inspection for wire damage and sensor orientation. Repair damaged wire and reposition the sensor and ladder clip if orientation is incorrect. If the initial repair does not correct the issue, replace the previous sensor with the 274-6717 Pressure Sensor (ATMOSPHERIC AIR). Reposition the sensor and ladder clip to the correct orientation of degrees of angle.
