Dispensing Coffe
The left tap delivers still cold brew which is refreshing and less acidic than hot coffe . The right tap delivers nitrogen-infused coffee which is the ultimate cold b ew experience. Thousands of micro-nitrogen bubbles are infused as the coffee is di pensed. This creates a naturally slightly sweet taste and thicker and smoother texture.

Troubleshooting

nitrogen tank is not empty and that the nitrogen shutoff switch is in the on position (in-line with the tube). Also assure that the knob on top of the tank is turned all the way counterclockwise. If the tank is empty, replace it with a full one.
Liquid and/or nitrogen ball lock disconnects are not fully connected to product tank.| Attach the liquid/nitrogen ball lock disconnects to the product tank. If they already appear to be connected, disconnect/ reconnect them.
The nose cone of the faucet is clogged.| Detach the nose cone assembly from the stout faucet by turning it counterclockwise. Remove the stainless steel restrictor disc and inspect the small holes to assure that none of them are clogged.
The system is dirty and requires a thorough line cleaning/sanitizing procedure.| Follow the line cleaning procedure above to remove buildup and restore full flo .
Too much or not enough nitrogen being infused into the product (head is too big or too small).| The secondary regulator is set to a pressure that is either too high or low.| If there is less/more nitro effect than desi ed, use the black knob on the secondary regulator assembly to make a change. To adjust the secondary regulator, pull the black knob out until you feel a slight click. This is the adjustment mode. To increase
the level of nitro, turn this knob clockwise. To decrease the level of nitro, turn the knob counterclockwise. Continue adjusting and pouring until the level of nitro meets your requirements. Once you have found your desired level of nitrogenation, push the black knob back in to lock it in place.
The strainer inside of the filter bowl assembly is beginning to clog.| See cleaning section
The system is dirty and needs cleaned.| See cleaning section
Liquid leak.| Loose connection, broken fitting/tub , or loose faucet, nose cone or filter bowl assembly.| Immediately turn the nitrogen off to the ystem, disconnect the quick disconnects from the product tank and call customer support for consultation to assess the system.

Cleaning

CLEANING VS. SANITIZING
This guide will address both the cleaning and the sanitizing of the unit.
Clean the unit to remove dried food and spills, to prevent build-up of grime, and to maintain the natural luster stainless steel surfaces.
Sanitize the unit when exposed to raw meat juice or human germs such as from a sneeze or being touched by someone who is ill. Sanitizing the unit can also be part of regular cleaning routine.
Stainless Surfaces
Stainless door panels, handles and frames can discolor when exposed to chlorine gas, pool chemicals, saltwater or cleaners with bleach.
Keep your stainless unit looking new by cleaning with a good quality all-in- one stainless steel cleaner and polish monthly. For best results use Claire’ Stainless Steel Polish and Cleaner. Comparable products are acceptable. Frequent cleaning will remove surface contamination that could lead to rust. Some installations may require cleaning weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on any glass surfaces.
Clean any glass surfaces with a non-chlorine glass cleaner.

Do not use cleaners not specifically intended for stainless steel on stainless steel surfaces (this includes glass, tile, and counter cleaners).
If any surface discoloring or rusting appears, clean it quickly with Bon-Ami® or Barkeepers Friend Cleanser® and a nonabrasive cloth. Always clean with the grain. Always finish with Clai e ® Stainless Steel Polish and Cleaner or comparable product to prevent  further problems.
Using abrasive pads such as ScotchBrite™ will cause the graining in the stainless steel to become blurred.
Rust not cleaned up promptly can penetrate the surface of the stainless steel and complete removal of the rust may not be possible.

CLEAN INTERIOR COMPONENTS
Use warm or hot water with dish soap to clean all removed components and interior surfaces. You may use a vinegar and water solution in place of soap. Proceed to sanitizing.
Note: Cleaning soaps and vinegar solutions are not sanitizers.
SANITIZE INTERIOR COMPONENTS AND SURFACES
Choose a Commercial Sanitizer Safe for Stainless Steel

• Read the directions for proper use to ensure that the surface will actually be sanitized
• Many products require rinsing with water after use, especially when food will be touching the surface
• Some products require a wait time before rinsing especially when food will be touching the surface
• Verify the sanitizer you are using is safe for stainless steel.
• Some products require a wait time before rinsing

Mix Your Own Sanitizer
Isopropyl Alcohol (rubbing alcohol)
