your safety officer to ensure proper precautionary steps are taken before bringing any new gas into
your facility. Toxic or flammable gases should never be used in the IoN 3 MHz.
Gas line integrity can be confirmed simply by opening the valve on the gas cylinder then quickly
closing it again. If the pressure reading on the regulator drops within one minute, there is a
substantial leak that could be dangerous.
Caution:
If oxygen is used
, “NO SMOKING” signs should be posted
near the
instrument and the no smoking ban observed.
NOTE:
The IoN 3 MHz system is designed to be used in a temperature range of 55-85 degrees
Fahrenheit and with a relative humidity of 10-90% noncondensing. The IP rating is IP20.

Interlocks
There are two double interlock switches on the IoN 3 MHz system case (on the top of the left side
cover and on the top of the back-right pump cover), and one single interlock switch that is activated
when the chamber door is closed.
DO NOT OVERRIDE THESE SAFETY INTERLOCKS.
These interlocks are engineered into the IoN 3 MHz to prevent injury to operating personnel. These
will shut off RF power if they are not activated. The chamber door must be closed for the RF to
activate. If all safety interlocks are connected, you will hear the fan activate when closing the
chamber door.
Care should be taken when replacing the electronics covers. The top cover interlock switches are
sturdy, but if broken, the system will not activate the RF. The double interlock switches should be
tested periodically.
An additional safety interlock is provided electronically through the VACUUM VALVE to prevent the RF
from activating unless the pressure system confirms that the IoN 3 MHz chamber is under vacuum.
WARNING:
DO NOT OVERRIDE THE SAFETY INTERLOCKS
