Safety guidelines & definitions
SECTION 2
Unit safety warnings
Do not operate the Nitro-Draught unit until the information contained in this document has been read
and understood by all personnel concerned. The unit should be connected to an electrical supply in
accordance with local safety regulations. Ensure that the rating plate corresponds to the supply
voltage. Ensure that the unit is grounded.
Nitrogen (N2) & carbon dioxide (CO2) are not poisonous gases but in a concentrated form present a
risk of asphyxiation. The Nitro-Draught unit produces a small flow of mixed gases that quickly
disperse in the atmosphere. However, do not directly inhale any gases produced by the unit. Refer to
Compressed Gas Association publications for further information.
Before service or maintenance is performed on the Nitro-Draught system, the electrical supply must
be switched off and the main electrical cord disconnected. All personnel handling, using or
maintaining the Nitro-Draught unit must employ safe working practices and observe all relevant local
health and safety regulations.
WARNING: The WARNING symbol draws attention to an operating
procedure or practice that can cause injury if it is not observed or
performed correctly. Do not continue past a WARNING symbol until you
have fully understood or satisfied the indicated conditions.
CAUTION: The CAUTION symbol draws attention to an operating
procedure or practice that can damage the unit if it is not observed or
performed correctly. Do not continue past a CAUTION symbol until you
have completely understood or satisfied the indicated conditions.

SECTION 3
Unit description & features
The Nitro-Draught blend gas dispense system extracts nitrogen (N2) from ambient air, blends it with
carbon dioxide (CO2) and supplies the mixed gas to a draught beer system. As a component of a
properly designed and maintained draught system, the Nitro-Draught assures brewery quality
beverage presentation while it eliminates excessive foaming and wasted beer.
The Nitro-Draught system uses proven Pressure Swing Adsorption (PSA) technology with Carbon
Molecular Sieve (CMS) to separate N2from the atmosphere and store it at a purity level of at least
99.8%. It uses a mechanical blender to combine the N2with CO2from another storage vessel into
CO2/ N2“beer gas” blend ratios, commonly two blends are used, 25% / 75% and 70% / 30%. Blends
can be customized for any application. Pure nitrogen can be withdrawn directly from the storage tank
to use in inert wine dispense equipment.
While in Production Mode, the internal air compressor will cycle on and off on approximately two
minute cycles. Each compression cycle will be followed by an exhaust cycle. At the start of the
exhaust cycle, an audible release of internal air pressure will occur. This compress-exhaust
alternating cycle will continue until the unit fully pressurizes the storage tank. At that point the unit will
move into Economy Mode, and power down all internal components after a few minutes. The Nitro-
Draught will enter into Economy Mode at “Switch Off” tank pressure and then return to Production
Mode when the tank pressure drops to “Switch On” pressure (see section 3.1 Technical
Specifications for settings), as nitrogen is used.
This manual contains the information necessary for the correct use of the Nitro-Draught. Should any
questions arise regarding safe and proper installation, operation or maintenance of the Nitro-Draught
system, contact the supplier before proceeding.
Warning: Ensure that all personnel involved in the installation,
operation and maintenance of the Nitro-Draught system, as well
as those persons who will act as supervisory personnel, have read
and fully understand the instructions before attempting to install,
operate or perform maintenance on the unit.

Installation & operation
4.1 Unpacking your unit
Remove the items from the box and check for damage. The box contains one Nitro-Draught unit, a
manual, and a power cord. If any of the items are in a damaged condition, request an immediate
inspection by the carrier. If any of the items are missing, please contact Fizz.
4.2 Powering up your unit
Installation quick checklist
1. Unpack and inspect unit
2. Mount unit to a solid and secure surface
3. Plug into suitable electrical outlet
4. Connect unit port “To Storage” to external pressure vessel and start nitrogen production.
Connect a return pressure line from external vessel to unit port “From Storage.
5. Make CO2and blend gas connections
6. Connect to draught and wine dispense system
7. Recheck connections and equipment for proper operation

SECTION 5
Maintenance & replacement parts
5.1 Recommended maintenance
Replacement of the compressor air compressor inlet filter, coalescing filter element and
exhaust silencer should be performed at least every twelve months or more frequently,
depending on environmental conditions. Cooling vents should be cleaned of any dust
accumulation during filter changes. Verify the unit is leak tight before returning to
service.
Before performing maintenance on a Nitro-Draught unit, disconnect the main power supply.
Failure to perform specified service may result in damage to the Nitro-Draught unit and may invalidate
any warranty. Use only genuine parts as supplied by Fizz.
The quality and reliability of the Nitro-Draught unit is maintained through preventive maintenance
performed on a scheduled, regular basis.
Keep a written record of all maintenance activity.
5.2 Maintenance service kits & instructions
Filter Replacement (Kit p/n 83108)
Switch off the electrical power supply before performing any service on a Nitro-Draught unit. Close
the “CO2Inlet” and N2To Storage” isolation valves. Depressurize the system by switching the unit on
again for 20 seconds allowing it to exhaust (and depressurize). Shut the unit off.
Replace the compressor air intake filter element:
1. Lift up tabs on both sides of filter assembly and pull cover off assembly.
2. Pull the used filter element from the housing cap and dispose of the used element.
3. Fit the replacement element by pushing the element, narrow end first, into the bottom of the
assembly.
4. Replace the cover by pressing it down onto bottom piece until it snaps tight.
Replace exhaust silencer:
1. Unscrew used silencer by turning counter clockwise.
2. Replace with new silencer, tightening only finger tight.
Replace the coalescing filter:
1. Make sure the housing is completely depressurized before continuing.
2. Unplug solenoid electrical connector.
3. Unscrew body/bowl of green coalescing filter.
4. Remove the element from the bowl and dispose in accordance with local waste regulations.
5. Carefully remove the new element from the packaging and insert into the bowl by aligning

proper tabs on element until it seats completely into bowl. There is only one proper
orientation. Screw bowl back into filter head until it seats.

5.4 Factory repair and refurbishment
Fizz will service any unit (whether within warranty period or not) at the request of the customer.
Authorization must be obtained from Fizz prior to shipping any equipment to Fizz facilities. The model
and serial number of the unit must be provided in order to process the return. The customer returning
the goods is responsible for all freight, proper packing, and any damage incurred during shipment of
the goods back to Fizz.
SECTION 6
Troubleshooting
Service or maintenance on the Nitro-Draught should be performed only by Fizz trained and
authorized professional service agents who are familiar with mixed gas pressure systems and all
pertinent safety and service procedures. Fizz recommends the use of Fizz approved replacement
parts.
Symptom –Low pressure in nitrogen storage tank
Low pressure in the nitrogen storage tank may have been caused by excessive demand from
the downstream system, such as a leaking keg coupler. Close the “To Storage” valve on the tank to
allow the generator to build pressure in this line (tank will be isolated). Pressure in the “To Storage”
line will be shown on the N2pressure gauge as well as the controller display screen. If the pressure
increases to “Switch Off” pressure and holds without leaking down, the unit is operating properly. The
storage tank and downstream system should be checked for leaks. Allow the generator time to refill
the storage tank.
If the “To Storage” line pressure does not increase after 3-4 compression cycles, the unit will
need to be serviced by a trained technician.
Symptom –Low blend gas pressure
Low blend gas pressure is usually caused by a lack of N2or CO2pressure coming into the unit.
Verify both of these gases are being adequately supplied to the Nitro-Draught unit.
