DESCRIPTION OF PRODUCT
The Medical IntelliSwitch™ is a device used to monitor, control and switch the flow of gas from cryogenic or high pressure cylinders
from either of two independent sources to either of two independently controlled and isolated delivery regulators. In turn these
regulators are connected to a single point of use output.
It consists of two electronically controlled inlet valves controlling the flow of gas into two electronically controlled valves that in turn
direct the flow of gas into one of two delivery regulators.
Pressure coming into the Medical IntelliSwitch™ is monitored and displayed on two independent 4-digit displays. The outlet pressure
of the system is monitored and displayed on a 3-digit display. Outlet pressure adjustment is available using an adjusting screw on the
delivery regulators inside the cabinet.
A series of indicator lights show the status of the system at any given time.
The status of the Medical IntelliSwitch™ may be monitored remotely via a serial port or optional Ethernet port. In addition, the
Medical IntelliSwitch™ can interface with a CONCOA Remote Alarm.
OPERATING THE MEDICAL INTELLISWITCH™
For a detailed explanation on the proper operation of the Medical IntelliSwitch™, refer to the CONCOA instruction manual ADI

IN-SERVICE REPAIR VS REPAIR CLASSIFICATION
Some repairs and adjustments can be made to the Medical IntelliSwitch™ while it is delivering gas to downstream users – these are
refered to as in-service repairs. Others require that the Medical IntelliSwitch™ be turned off in order to perform the necessary repairs.
Throughout this manual, each section will indicate either ‘IN-SERVICE REPAIR’ or ‘REPAIR’
CAUTION: When a REPAIR is needed and the unit must be turned off to complete the necessary repairs, actions must be taken to be
able to provide gas to the downstream users.
