3.2 Installation of the System
The system should be located indoors on a flat surface, and be protected from direct sunlight, moisture, and
dust (Refer to section 2.1 of this user guide for the system’s environmental specification). When considering
the final location of the system ensure that:
• The system is positioned within easy access of the electrical supply.
• There is adequate space available around the system for ventilation, maintenance access.
• Casters are locked when system is in position.
• The tubing is NSF ¼ in (.63 cm) with 150 psig (10.3 bar) pressure rating.
• Max length of tubing: 300 ft (91.4 m).
• Clearance: Top, bottom, left and right sides: None. Back 6 - 8 inches (15.2 cm - 20.3 cm) to allow
clearance for tubing and power cord, Front: Minimum 12 in (30.5 cm) to allow for ventilation.
Due to the nature of operation, there is a possibility of oxygen enrichment surrounding the
system. Ensure that the area is adequately ventilated. Where the risk of oxygen enrichment
is high, such as a confined space or poorly ventilated room, the use of oxygen monitoring
equipment is advisable.
The DN-6 Series is capable of delivering nitrogen at a flow rate of 6 SCFH (2.8 lpm). Nitrogen is
not a poisonous gas but, in a concentrated form, there is a risk of asphyxiation. If the system
is operated within a confined space ensure that adequate ventilation and oxygen monitoring
equipment is fitted.
DO NOT
• Position the system so that it is difficult to operate or disconnect from the electrical supply.
• Position the system directly above electrical equipment as condensate may collect at the base
of the system.
• Use noxious chemicals or machinery that produces fumes within a 20 ft (6 m) radius of the system.

4 Operating the equipment
4.1 Starting the equipment
1. Install the equipment at the desired location and plug the electrical cord into a properly grounded
electrical outlet.
2. Press the power switch ON (symbol “I” illuminates green) located at the rear of the unit to start the
system. DO NOT CONNECT THE DOWNSTREAM EQUIPMENT YET. The cooling fans will start immedi-
ately and after approximately 2 minutes the on-board compressor will start.
3. Initially, the RED, ”SYSTEM FAULT” light on the front panel will illuminate because the internal nitrogen
storage tanks are empty. Allow the system to operate normally until the pressure gauge displays a pres-
sure within the GREEN range (75-85 psig (5.1-5.9 barg)) and the GREEN “READY” light illuminates (6-8
minutes). The RED, ”SYSTEM FAULT” light will go off.

4. The compressor will continue to cycle on and off about every 2 minutes until the internal nitrogen storage
tanks are fully pressurized.
5. With no nitrogen being withdrawn from the output fitting, the system should go into standby mode within
a short time and the cooling fans will stop. Allow the system to sit for an additional 15-20 minutes before
connecting any output tubing. During this time the compressor should not operate. If the
compressor operates during this time, it may indicate an internal system leak.
6. Connect the tubing barb valve coupling to the downstream tubing. Then connect that coupling to
the Nitrogen Outlet Port coupling on the back of the system. Make sure that the downstream tubing
has a check valve (not supplied) to prevent back-flow. Refer to section 3.1 for recommended
installation diagram.
7. Nitrogen will immediately begin pressurizing the dispensing system to approximately 80 psig (factory
preset), and the system should come out of standby mode, as indicated by the operation of the cooling
fans. If the internal tanks are de-pressurized sufficiently, the compressor will begin to cycle on and off
to re-pressurize the internal storage tanks.
8. The system should now be ready for supplying nitrogen and will maintain approximately 80 psig output
pressure as nitrogen is withdrawn from the system.
9. If the RED, ”SYSTEM FAULT” light comes on during use, it may: (1) indicate a gas leak in the dispensing
system causing an excess of nitrogen to be withdrawn from the system or (2) indicate an over-temper-
ature condition in the system caused by insufficient cooling air flow. This could be caused by debris
blocking the inlet duct at the bottom-rear of the unit next to the floor, or an obstruction of the exhaust
vent located at the front of the unit.
Refer to Section 2.1 Technical Specifications for ambient temperature specifications.
The nitrogen generation process will consist of a compressor run sequence followed immediately by
an exhaust sequence. These cycle times vary depending upon the model of generator as shown below.
An audible pressure release will indicate that the unit is producing nitrogen.
Model Compressor Run Time
(Seconds)
Exhaust Time
(Seconds)
DN-6 Series 130 120
The system will initially take 15-30 minutes to fully pressurize the internal storage tanks with
no nitrogen being withdrawn from the system.
The system is designed to run continuously and requires no further intervention, other than
regular scheduled maintenance. (See Section 5 for maintenance instructions).

14
Standby Mode
In the event of zero flow, the system cycle will continue until the internal tanks are fully pressurized
whereupon it will enter standby mode. In standby mode, the unit will cease cycling and the fans will turn off.
When the nitrogen pressure falls below a predetermined set point the unit will re-enter normal operation and
the cooling fans will start, followed by cycling of the compressor.
4.2 Shutting Down the System
1. Push the power switch to the “OFF” position (O) and ensure that the green illumination of the switch is off.
Make sure that the power cord is unplugged before performing any maintenance and service.
Failure to do so may result in electrical shock or serious injury.
4.3 Depressurizing the System
Follow this procedure to depressurize the system before
performing any maintenance or service.
1. Push the power switch to the ‘OFF’ position (O) and
unplug the cord set.
2. Remove the system’s cover to access internal components.
3. Loosen the bleed screw (See Figure 5) by turning
counter-clockwise by hand, 2-3 turns until gas can be
heard escaping.
4. Allow the system to de-pressurize until the pressure
gauge on the front of the unit indicates zero pressure.
5. Once the system is relieved of pressure, re-tighten the bleed
screw by turning clockwise while the system is depressurized.
Figure 5: Bleed Screw
The generator will remain pressurized after shut down. Before performing any maintenance
or opening any piping systems, always depressurize the system. Failure to do so may result
in injuries.

15
5 Maintenance
It is essential that the system is powered down and fully depressurized before carrying out
any servicing procedures (Refer to sections 4.2 and 4.3)
The quality and reliability of the system is maintained through preventative maintenance performed on
a scheduled, regular basis. Although the frequency of this maintenance is determined by particular use
conditions, it is recommended that filter elements are changed at least every twelve months.
5.1 Cleaning
Clean the system with a damp cloth only and avoid excessive moisture around any electrical components. If
required you may use a mild detergent, however do not use abrasives or solvents as they may damage the
warning labels on the equipment.
5.1.1 Exterior
It is highly recommended that an internal inspection of the unit be performed after the first 6 months of
operation following installation. One of the main purposes of this inspection is to check the hour meter on
the PLC. See section 5.4.5 for accessing the hour meter on the PLC. Access and record the number of
RUN hours and ECO hours for the unit operation as shown on the PLC display. In general, the number of
ECO hours should be many times that of the RUN hours (for example, for 1 year of operation, 400-600 hours
of RUN time, and 8000 hours or more of ECO time would be considered normal). The number of ECO hours
should be ten to fifteen times that of the number of RUN hours for a leak tight system. If the number of ECO
hours is only two or three times the number of RUN hours, this indicates that the system likely has nitrogen
leaks either internally or externally causing the compressor to operate excessively and reducing the life of
the system. With a high number of RUN hours, the system’s replacement filters will need to be changed out
more frequently in order to maintain optimum system performance and reduce the chances of further system
damage.
To check for internal leaks, the nitrogen outlet tubing can be disconnected from the generator and the
compressor operation monitored. With the outlet tubing disconnected, if the compressor operates more
than once per hour, then internal leaks are likely and leak test solution (soap + water) can be used to isolate
internal leaks. If the compressor does not operate with the outlet tubing disconnected, and there are a high
number of RUN hours, then leaks in the coffee dispense system are likely (keg o-rings, etc). Find and repair
any dispense system nitrogen leaks to minimize the number of RUN hours of compressor operation. Re-
connect nitrogen output tubing once internal system leaks are checked and repaired if necessary.
With the cover removed, vacuum any excessive dirt and dust from the air intake duct area, exhaust screen,
and check coalescing filter for debris. Replace any filters if necessary, especially the coalescing and
compressor air intake filter if an excessive number of run hours are observed.
