Minimum Circuit Ampacity
The minimum circuit ampacity is used to help select the
wire size of the electrical supply. (Minimum circuit ampacity
is not the N2Fusion System’s running amp load.) The wire
size (or gauge) is also dependent upon location, materials
used, length of run, etc., it must be determined by a
qualified electrician.
Voltage
A dedicated electrical circuit is required, a power cord
is provided with all units. Some models are available in
different voltages and may be equipped with a different
plug.
The following precautions must be observed:
• The equipment must be grounded.
• A separate fuse/circuit breaker must be provided for
each unit.
• A qualified electrician must determine proper wire size
dependent upon location, materials used and length
of run (minimum circuit ampacity can be used to help
select the wire size).
• The maximum allowable voltage variation is ±10% of
the rated voltage at equipment start-up (when the
electrical load is highest).
• Check all green ground screws, cables and wire
connections to verify they are tight before start-up.
Preparing the power cord (International units only)
The following instructions cover the installation of a 220
VAC, 50/60 Hz (international) unit. An appropriate 3-wire
power receptacle must be located within 6 ft (1.8 m) of the
unit. Unpack the unit from its transportation packaging and
visually check for any signs of damage.
NOTE: Only use an approved plug for the country in which
the unit is being installed.
Important
The wires in the power cord/mains lead are colored in
accordance with the following code:
• Green / Yellow = Ground/Earth
• Blue = Neutral
• Brown = Line/Live
1. Locate a 3-terminal plug. This plug (not furnished with
unit) must have a ground-wire-connecting terminal.
2. Locate the loose end of the power cord attached to
the unit. All three (3) wires are stripped to 1/2" (1.3 cm)
length from the end.
3. Connect all three (3) wires to the plug using the
1/2" (1.3 cm) stripped ends or any other terminal
requirements. Different plugs and terminals may
require different stripped lengths.
4. Inspect the cord and plug connection for any loose or
bare wires.

a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded/
earthed in accordance with all local codes and ordinances.
Check with a qualified electrician or serviceman if the
grounding instructions are not completely understood or if
in doubt as to whether the product is properly grounded.
Do not modify the plug provided; if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.

REMOTE TOWER INSTALLATION
These instructions are only for units that require remote
Mounting & Routing
placement of the dispensing tower. If this is a self contained
unit with out remote setup continue to “Nitrogen Regulator
& Tank Assembly” on page 13.
Checklist
Make sure the rubber counter top gasket is in place on
the tower before routing conduit and mounting tower.
Important
Tower location should be no more than 20.70"
(53 cm) from edge of the counter.
TAP #2
Nitro/Gas

TAP #1
Plain
base cabinet.
Make sure location has space for the drip tray
shipped with the unit.
NOTE: Drip trays equipped with a drain are also available
but are not standard equipment.
Location
1. Identify the counter top location for the tower making
To Cabinet

the 2" (5 cm) conduit and tower mount screw holes will
be drilled.
4. Route conduit from the tower down through the 2in
(5 cm) hole and mount the tower to the counter top
with the provided plate and screws.
NOTE: Make sure the rubber gasket is properly seated on
the tower and seals to the counter top.
5. Run the conduit from the tower to the N2Fusion™ cabinet.
6. Remove the two (2) screws from the solenoid cover
mounted to the inside top of the cabinet to gain access
to solenoids 1 and 2.
3. Cut and drill holes in the counter using the markings.
NOTE: Drip trays equipped with a drain will need a 7/8"
(2.22 cm) hole drilled into the counter using the provided
template for routing to a floor drain.
7. Route tubing through the top of the cabinet and attach
to the corresponding solenoids.
NOTE: Tubing already routed to the solenoids in the cabinet
should be marked with yellow 1 & 2 stickers.

NITROGEN REGULATOR & TANK ASSEMBLY
DANGER
Tank under high pressure. Do not drop or allow tank to
fall over. Tank must be chained and secured to prevent
movement as per OSHA requirements. Do not attempt to
handle or connect to tank unless properly trained.
NITROGEN IS AN ASPHYXIANT GAS. A LEAK IN AN
ENCLOSED AREA COULD DISPLACE OXYGEN AND CAUSE
ASPHYXIATION. ALWAYS TEST GAS HANDLING SYSTEMS
FOR LEAKS. A N2 GAS DETECTOR IS RECOMMENDED.
Nitrogen cylinders contain high-pressure gas which can
be hazardous if not handled properly. Make sure you READ
and UNDERSTAND the following procedures for nitrogen
cylinders BEFORE installation.
6. ALWAYS check the D.O.T. test date on the cylinder neck
before installation. Ask your gas supplier for D.O.T. test
requirements.
7. NEVER connect a product container unless there is
a safety in the pressure system at or on the nitrogen
regulator.
NITROGEN INSTALLATION/REPLACEMENT
NOTE: During initial installation of the unit a bracket for the
nitrogen cylinder must be installed to solid wall nearby and
a chain used to secure it to the bracket.
Warning
n
Verify gauge orientation
before setting pressures!

INTEGRAL SAFETY
DEVICE
Important
Use only food grade nitrogen (99.5% pure).
1. ALWAYS connect the nitrogen cylinder to the primary
regulator and NEVER directly to the unit, keg, or
dispensing system. Failure to do so could result in
an explosion with possible death or injury when the
cylinder valve is opened.
2. ALWAYS follow correct procedures when cylinders are
changed.
3. ALWAYS secure the cylinder in an upright position with
a chain.
4. NEVER drop or throw a nitrogen cylinder.
5. ALWAYS keep a nitrogen cylinder away from heat.
1. Make sure cylinder valve “A” is closed.
2. Unscrew (counter clockwise) regulator key “B” as far out
as it will go. (The regulator is now in the off position.)
3. Remove regulator from empty cylinder at “D”.
4. Remove dust cap from new cylinder at “D”. Open and
close valve “A” quickly to blow dust from outlet.
5. With cylinder valve “A” in closed position, re-attach
regulator to cylinder at “D”.
6. Open valve “A” all the way. (This is important because
this cylinder valve seals in two places.)
7. Screw regulator key “B” in (clockwise) until required
pressure is reached “E”.
NOTE: Drinks will not pour if outlet valve “A” is closed.
Store extra cylinders in a cool place (preferably 70°F).
Securely fasten with a chain in an upright position
when storing.
