8.2. Checking for Leaks
The BlastOff
®
provides early warning alarms for potential leakage. With a suspected leak, first, listen
for leaks and spray soapy water around the connections. When a leak occurs, isolate the area, and
relieve pressure before working on it. Fix the leaking part and return the system back to operation. If
no leak is heard (or bubbles visually seen with the soapy water), turn off the unit and try isolating
sections to see if there is a pressure loss. Consult with your installer if you cannot find the leakage
area.
To determine if the leak is between the Generator and the Nitrogen Tank:
1. With the unit powered on, close off both ball valves on the nitrogen tank. Note the storage tank
pressure.
2. Allow the system to continue running. Within 10 minutes or less, the system should reach the
“Standby” mode.
3.
Wait 5 minutes and if the system remains in “standby” mode, then the leak is after the nitrogen
generator. Read the nitrogen tank pressure and if the pressure has changed, the leak is within
the storage tank fittings. If the nitrogen tank pressure did not change, check the pipelines in the
building for leaks.
4.
Returning to “run” mode indicates the leak is within the cabinet. Check lines back to the tank.
