FAQS
11.1 POWER ISSUES
If the N
2-BLAST
®
FPS-500 does not have power, the production and storage of nitrogen will
become apparent once the storage pressure drops.
1. Check the power cord.
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 N
2-BLAST
®
FPS-500 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 rell the storage. If you are
out specications, 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 re protection system is being tested.
• Check leaks throughout system.
Refer to section 8.2 Checking for Leaks.
11.3 GAS LEAKS
As with any gas system, only use a spray bottle on non-electrical equipment to nd leaks. Fix or
replace leaking ttings or old hose. Push-to-connect ttings will show bubbles and typically have
up to a 5ccm acceptable leakage rate. Contact your local provider/installer for help.
