Installation, Operation & Maintenance
STEP 2.
•
Ensure you have the correct gas for the device type prior to application.
•
Screw the regulator/valve into the gas cylinder outlet.
•
Once sealed, the regulator pressure gauge (if available) will indicate cylinder pressure.
•
Offer up the applicator hose/cone and fully cover the sensing element on the front case.
•
Open the valve/regulator to allow the gas to be delivered at a pre-set flow rate.
•
Apply gas.
•
The detector Alarm LED will illuminate at the alarm set point.
•
Remove applicator hose/ cone and turn the gas cylinder regulator/valve off.
•
Wait for detector to stabilise / return to normal.
•
Reset the service reminder by shorting out the unmarked header.
•
Test complete.
Always remove the regulator/valve after use - All cylinders will re-seal upon removal of the regulator!
Never use expired or 'near empty' gas cylinders!
Always give at least five (5) minutes between testing the same unit or until gas has fully dispersed!
Always consider safety and use equipment in accordance with Safety Data Sheets!
