GAS CYLINDER REMOVAL INSTRUCTION
A nitrogen gas cylinder is under extremely high vapor pressure which will need to be handled with care during
disconnect from the dispenser. Nitrogen cylinders will have a DOT label identifying the gas and hazards.
Step 1:
Locate the N
2
supply cylinder and verify it only supplies nitrogen to the BUNN nitron
2
Cold Draft
dispenser only.
Step 2:
Turn the main cylinder On/Off valve to the Off position.
Step 3:
Place an empty container under the dispenser nozzles. Pull the “Nitro Coffee” tap handle to relieve the
pressure.
Step 4:
Disconnect the nitrogen supply line to the dispenser.
Step 5:
Disconnect the nitrogen pressure regulator from the cylinder.
Step 6:
Inform the location manager or owner that the Nitrogen cylinder is disconnected and should
be properly stored until gas supplier can pick up.
NOTE:
During removal, if the cylinder is empty, tag the cylinder as “Empty”.
Step 7:
Disconnect or unplug the Nitron
2
Cold Draft dispenser from the power source.
Step 8:
Proceed onto Step 2 under NGM Initial Set Up Instruction.
NGM Initial Set Up Instruction
Step 1
: Determine if the Nitron Gas Module (NGM) is going to be installed to an existing installed Nitron
2
Cold Draft dis-
penser using N
2
gas supply from a cylinder or along side a new dispenser installation.
Existing Nitron
2
Cold Draft Installation - Go to “N
2
Gas Cylinder Removal Instruction” before continuing with Step 2.
Step 2:
Place the Nitron Gas Module (NGM) near or under the Nitron dispenser. Adjust to extend the feet of the Nitron
dispenser approximately 1.0 inch to accommodate NGM placement underneath the Nitron dispenser.
Note:
The Nitron dispenser must be disconnected from the power source until specified in the instruction to power up
dispenser.
Step 3:
Locate the hose and sealing washers that came with the Nitron Gas Module, install the flare washers upon con-
necting the hose from the NGM to the Nitron dispenser flare fitting for proper seal at the flare connections.
Step 4:
Plug-in the NGM power cord into a dedicated 120Volt, 15Amp rated outlet.
Step 5:
Wait a few seconds for the NGM to pressurize the line between the NGM and Nitron dispenser and shut off.
Check for leaks.
Step 6:
Before installing a door cover or an existing door cover on a Nitron dispenser, disable the red LED indicator
light (for an empty N
2
tank) mounted on the inner door by disconnecting the connectors. Locate the black and red
wire coming from the red LED going to a 2-pin connector junction (Fig.1). Disconnect the 2 pin connector (Fig.2). Next,
follow the Door Cover Installation instruction outlined in the Nitron
2
Installation & Operating Guide.

Disconnected
Step 7:
After completion of disconnecting Nitron dispenser’s red N
2
Empty LED and Nitron Door Cover Installation, the
dispenser can be connected to a power source. The NGM is now ready for use. As the pressure is depleted by dispensing
drinks from the Nitron dispenser, the NGM will automatically turn on to re-pressurize the line.
