Does my system need to be connected to a facility exhaust? If so what should be connected?

Connection of the facility exhaust is optional and not strictly needed for system operation. For the installation and startup of a system, facility exhaust is not normally required.

While connecting the system to an exhaust is not required for proper operation, it is strongly recommended on systems where potentially hazardous substances are used.

If you choose to connect your system to an exhaust the main things that normally need to be connected are the purge valve, vacuum pump, and regeneration exhaust outlet.
