make the correction.
c.
If there is a leak within the unit, remove the cover and locate the
issue. If you must replace any parts, only use factory parts
supplied from your distributor or South-Tek Systems. Consult
the factory if there are any questions.
5.
Once the
N
2
-BLAST
®
fills the 100# storage tank to 70 PSIG, the system
will enter standby – the system’s green N
2
Production light will change
to orange indicating that the system is in standby. This will shut the air
flow off through the generator and eventually shutting off the air
compressor once it reaches air tank cutout pressure.
a.
This will save air and time on your compressor’s motor.
b.
This also prolongs life of nitrogen generator’s media and filter life.
i.
Lesser quality systems have a constant purge flow
through their systems which decreases system life and
increases the need for maintenance.
6.
When you draw N
2
off the system and the tank pressure falls below
cut-in pressure (approximately 62 PSIG), the pressure switch will trigger
the system back into run mode and start recharging the storage tank
automatically. The pressure switch is preset at the factory – no field
adjustment is required.
CHECKING FOR LEAKS
When a leak is suspected, first try to listen for leaks and/or spray with soapy
water around the connection ports. If a leak is found, isolate the area and
relieve any pressure on it prior to working on it. Fix the leaking part and return
the system back to operation. If no leak is heard (or visually seen with the
soapy water), turn off the unit and try isolating sections to see if there’s a
pressure loss. If the BlastOff™ option is included with your unit, the system
will alarm indicating that there is a leak in the line. Consult with your installer
if you cannot locate the leakage area.
To determine if the leak is within the Generator to the N2 Storage Tank:
1.
With the unit powered on, close off both ball valves on the N2
storage 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 for 5 minutes and if the system remains in the “standby”
mode, then the leak is after the N2 Generator. Read the N2
storage tank pressure and if the pressure has changed, the leak
is within the storage tank fittings. If the N2 storage tank pressure
did not change, check the pipe lines in the building for leaks.
