4.2.2.6 Replacing the Differential Pressure Switch

Prerequisites

●

The differential pressure switch needs to be replaced.

●

A spare differential pressure switch of the same model is available and

functional.

●

Tool: Phillips screwdriver

Context

The differential pressure switch can be maintained only from the rear door.

Procedure

Step 1 On the controller home screen, tap Shutdown, and turn off the smart cooling

product switch in the upstream PDC.

NO TICE

Exercise caution because the device is still energized after it is shut down on the
