The PSKIT8100 pressure sensor is designed for use with the EH8100 Series enclosure. The sensor ensures 
that enclosure pressure stays at an acceptable operation level. The PSKIT8100 provides contact closure 
when the internal pressure of the enclosure falls below the required 5 psi.

1. Disconnect power to the enclosure.

2. Remove the ground wire from the ground stud on the back of the enclosure.

3. Remove the electrical connector from the rear of the enclosure. Turn the outer ring counterclockwise 

and pull off the mating portion of the connector.

4. You may remove the enclosure from its mount to make the installation process easier.

5. Remove the cap from the Schrader valve (refer to Figure 1).

6. Relieve internal enclosure pressure by depressing the center stem of the Schrader valve. 

7. Remove the rear plate of the enclosure (refer to Figure 1) and perform the following steps:

a.

Use a screwdriver to pry the end of the spiral retaining ring from the retaining ring groove.

b.

Pull on the T-handle to remove the rear plate from the housing.
