SECTION 1 – EQUIPMENT OVERVIEW Thank you for purchasing CARON equipment! Before using the equipment, familiarize yourself with key components of the product and thoroughly read this manual.
SECTION 2 -- INSTALLATION High concentrations of many gases can cause asphyxiation. The use of monitors and alarms is recommended for areas where gas can collect. Model GASG201 is designed to work with N2 or CO2. Do not connect this unit to a combustible gas source. The model GASG201 Stand Alone Gas Guard from CARON is designed to allow two tanks of either CO2 or N2 to be connected to an incubator requiring approximately 15 psig of gas pressure.
Once the cylinder regulators are installed and adjusted on each tank, connect the outlet of the regulator on Tank 1 to the hose barb fitting labeled Tank 1 on the back of the unit using the tubing and clamps provided. Repeat the process for Tank 2. The gas outlet connection on the back of the unit can then be connected to the incubator using the supplied tubing and clamps. Turn on the regulated gas supplies and check the connections closely for leaks.
The factory default “master tank” is Tank 1. When the appropriate gas pressure is supplied to both tanks, the master tank will always be used as the gas source. The unit will swap from the master tank to the alternative tank whenever a low gas pressure condition is detected. The alarm switch is used to disable the audible alarm when a low gas condition is detected. The audible alarm can be silenced while a new tank is installed by selecting the silence position.
