Connecting Vacuum Pumps

Connecting Vacuum Pumps and Filter Chambers to the Network

Make sure that all previous installation steps have been done first before starting this task. You’ll use two yellow patch cords to connect.

To connect a vacuum pump to the network:

1.Attach one connector of the first yellow patch cord to the lower terminal on the vacuum pump terminal box. Tighten the cord grip ring until snug.

2.Attach the other connector to the upper left terminal of the ArmorBlock. Tighten the cord grip ring until snug.

3.Attach one connector of a yellow patch cord to the upper terminal on the vacuum pump terminal box. Tighten the cord grip ring until snug.

4.Attach the other connector to the upper right terminal of the ArmorBlock. Tighten the cord grip ring until snug.

Note: Retain the terminal caps from the ArmorBlock. They may be used later.
