Number

Description

1

Pipe fitting - Nitrogen supply to the seal purge.

2

Label - Warning; If the pump has overheated or the cooling water has failed, connecting 
cooling water to a hot pump will cause severe damage to the pump.
Always allow the pump to cool for at least 20 minutes before connecting the cooling water.

3

Label - Warning; do not remove cover until 4 minutes after disconnecting power from the 
pump.

4

Gas supply fitting - Connect the gas supply to this connection. This compression fitting accepts 
1/4 inch (6.35 mm) diameter tube. Ensure that the tube used is suitable for your application.

5

Label - Gas Module identifier.

6

Pipe fitting - Nitrogen supply to the gas ballast.
