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 1200 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 1200 assures brewery quality
beverage presentation while it eliminates excessive foaming and wasted beer.
The Nitro-Draught 1200 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 60% / 40%.
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 Pure nitrogen can be withdrawn directly from the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 1200 will enter into Economy Mode at 100 psi tank pressure and then return to Production
Mode when the tank pressure drops to 90 psi, as nitrogen is used.
This manual contains the information necessary for the correct use of the Nitro-Draught 1200.
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.
Warning: Request assistance from another person or persons
when lifting or moving this product. Physical damage or personal
injury may result from a single person attempting to lift or carry this
product.

SECTION 5
Maintenance & replacement parts
5.1 Recommended maintenance
Replacement of the compressor air inlet filter 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 1200 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
(Filter Kit P/N 82000)
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.

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 1200 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 100 psi 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 2-3 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.

SECTION 7
