11. FAQs
11.1. Power Issues
If the N2-BLAST
®
FPS-900 does not have power, the production and storage of nitrogen will
become apparent once the storage pressure drops.
1.
Check the power supply cables for connection and voltage.
2.
Has the building’s circuit breaker or GFCI tripped? Locate the breaker and
reset. If breaker
continues to trip, you may have that circuit overloaded.
11.2. Pressure Issues
The N2-BLAST
®
FPS-900 will produce and store Nitrogen (N2) at 70 (+/-3) psig. Once the storage
tank reaches 70 (+/-3) psig, the system will go into Standby Mode. When the pressure drops by
about 7-10 psig, the system should go into Run Mode and begin to refill the storage. If you are out
specifications, we need to determine where the issue is. Contact the manufacturer or factory trained
technician.
Nitrogen Pressure Check:
The pressure gauge on the front of the cabinet should be between 60 and 70 PSIG. If the pressure is
low, check the following:
•
Check the power.
•
Find out if fire protection system is being tested.
•
Check leaks throughout system.
Refer to section 8.2,
“
Checking for Leaks
”
.
11.4.
Gas Leaks
As with any gas system, only use a spray bottle on non-electrical equipment to find leaks. Fix or
replace leaking fittings or old hose. Push-to-connect fittings will show bubbles and typically have
up to a 5ccm acceptable leakage rate. Contact your local provider/installer for help.
