If your system requirements are more complex, please consult your sales representative or equipment installer for
more detailed installation instructions.
1.
The BrewBlast
™ BrewBlast™ 70CPH
is supplied with
½” NPT female inlet and outlet fittings. Make sure to use
Teflon tape or similar on all fittings so they do not leak.
2.
Connect the BrewBlast
™ BrewBlast™ 70CPH
to the storage tank and then to the coffee system.
3.
Once connections are made, slowly open the syst
em’s On/Off Valve.
A. You will hear air rushing through the system and N
2
filling the BrewBlast
™ BrewBlast™ 70CPH
storage tank.
B. If you hear a leak or have a bad connection, shut the valve off and make the correction.
C. If there is a leak within the unit, remove the cover and locate the issue. If you have to replace any
parts, use only factory parts supplied from your distributor or South-Tek Systems. Consult the
manufacturer if there are any questions.
4.
Once the BrewBlast
™ BrewBlast™ 70CPH fills the storage tank to 85 PSIG, the system will enter standby – the
system’s green N2 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 shut off the air compressor once it reaches the air
tank cutout pressure.
A. This will prolong the life of your compressor
’s motor.
B. This also prolongs the life of the nitrogen generator
’s media and filter.
i. Lesser quality systems have a constant purge flow through their systems which decreases
system life and increases the need for maintenance.
5.
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 around the connection ports. If a leak is found, isolate the area
so that there is no pressure on it. Fix the leaking part and return the system back to operation. If no leak can be
heard, turn off the unit and try isolating sections to see if there is
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 cabinet:
A. With the unit powered on, close off all output gas. If no ball valve is installed on the output ports, it is
recommended to remove the gas lines and install a plug.
B. Allow the system to continue running. Within 1 h
our, the system should reach the “Standby” mode.
C. Wait for 5 minutes
and if the system remains in the “standby” mode, then the leak is after this point.
Check the gas lines exterior to the cabinet all the way back to the keg system.
D.
If the unit goes back into “run” mode, the leak is within the cabinet. Check all the lines going to the
blender and back to the tank.
To find the leak within the cabinet:
1. Open the front cabinet door and locate the N
2
storage tank.
2. Close off the output ball valve from the tank (upper ball valve on the red manifold).
3. Watch the exterior gauge above the cabinet for 60 seconds. If you see the pressure dropping, the
leak is somewhere between the output ports, to the blender (if one is present), and back to the closed
off ball valve on the tank. Fill and/or listen for leaks and fix them once found. If the pressure is not
dropping, go to the next step.
4. With the unit still running, close off the input ball valve to the tank (lower ball valve on the red
manifold).
5. Within 5 minutes, the system should go into
“Standby” Mode. If it doesn’t, contact your local
provider/installer for further assistance.
