Air Intake Filter
The integrated air compressor, of the N2-Blast
®
FPS-900-
RS, has an air intake pre-filter. It prevents particles from entering
the compressor housing and damaging internal components.
Replace this filter once per year or every 1000 hours, whichever
comes first. To do so, remove the pre-compressor filter cap by
twisting it clockwise. Remove the old element and use a clean
dry cloth to clean the filter bowl before installing the new ele
-
ment.
Air Filter Replacement
The particulate and coalescing filters, after the air compres
-
sor, are designed to capture particulate
and moisture prior to entering the rest of the system. These fil
-
ters need to be replaced once per year or every 1000 hours,
whichever comes first.
Note: Annual Filter replacement kit part # FRP-007
Follow these instructions to replace filters:
1. Turn off the unit and remove the front cabinet door.
2.
Locate the air filters on the bracket in the top-left of the
cabinet (see Figure 10).
3.
Make sure the filters are completely depressurized by
checking the pressure gauge.
4.
Remove both filter bowls by turning them counter-
clockwise.
5.
After removing the filter bowls, rinse debris out of the
bowls with warm water.
6. Dry the bowls with a clean dry cloth and replace old
O-rings with the ones in the kits and lubricate the seals.
7.
Change the filter elements:
a. Particulate Element - Pull the plastic element hous-
ing out of the filter bowl. Twist off the black plastic cover
and pull off the particulate element. Install the new ele-
ment in the reverse order.
b. Coalescing Element - Twist the coalescing element
counter-clockwise. Install the new element in the re-
verse order.
8. After replacing all elements and O-rings and cleaning
the bowls, install the bowls back to their corresponding
filter housings. Hand-tighten only.
After replacing the filters, check the filter bowls for leaks by turn
-
ing on the unit momentarily. Turn the unit off to reinstall the front
cover and then power the unit back on. Once powered up, the
air compressor will turn on and the system will start producing
nitrogen.

FAQS
1. Power Issues
If the N2-Blast
®
FPS-900-RS does not have power, the produc-
tion and storage of nitrogen will become apparent once the stor-
age pressure drops.
• Check the power cord.
• 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.
2. Pressure Issues
The N2-Blast
®
FPS-900-RS will produce and store Nitrogen (N
2
)
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 will go into Run Mode and begin
to refill the storage tank. Contact the manufacturer or factory
trained technician if system does not properly operate within
these ranges
Nitrogen Pressure Check:
The pressure gauge on the storage tank 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 for leaks throughout system.
3. Leaks
As with any gas system, only use a spray bottle on non-electri-
cal 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.
