SHIPPING AND STORAGE

CAUTION:

UNIT LOCATION

Cold Nitro Brew BIB Dispenser Operator’s Manual

Before shipping, storing, or relocating the unit, the unit must be sanitized and all sanitizing solution must be drained from the system. A freezing ambient environ‐ ment will cause residual sanitizing solution or water remaining inside the unit to freeze resulting in damage to internal components.

The CNB BIB unit is not suitable for installation in an area where a water jet could be used.

POWER CORD

The CNB BIB unit must be located in a horizontal position.

This CNB BIB unit is not designed for use in outdoor locations.

If the power cord is damaged, it must be replaced by a special cord available from the manufacturer or its service agent.

SOUND LEVELS

The A‐weighted sound pressure level has been determined to be below 60 dBA.

UNIT CLEANING

GROUNDING INSTRUCTIONS

This CNB BIB unit MUST NOT be cleaned by using a water jet.

This appliance must be grounded. In the event of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance Is equipped with a cord having an equipment‐ground‐ ing conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly Installed and grounded in accordance with all local codes and ordinances.

Improper connection of the equipment‐grounding conductor can result In a risk of electric shock. The conductor with green insulation with or without yellow stripes Is the equipment grounding conductor. If repair or replacement of the cord or plug Is necessary, do not connect the equipment grounding conductor to a live terminal. If in doubt whether the appliance is properly grounded, check with a qualified electrician or serviceman. Do not modify the plug provided with the appliance ‐ if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

This appliance is for use on electrical circuits, as shown in Table 1, and has a ground‐ ing plug that looks like the plug illustrated in Figure 1.

UNIT MAINTENANCE

DAILY MAINTENANCE

Use only products approved by Cornelius in the CNB BIB unit. Failure to do so can result in reduced unit performance or render the unit inoperable.

Perform the items listed in Table 2 on a daily basis.

Step Action

2 Wash and rinse the drip tray grate.

3 Check tap nozzles for coffee grains and clean if required.

4 Check the level of the product BIB.

Table 2.

Wipe the outside, inside, tower, drip tray and taps of the dispenser with a clean disposable towel.

If using a nitrogen generator, be sure the generator is operational and the gauge shows pressure.

If using a nitrogen tank, check the primary nitrogen tank pressures: the pri‐ mary side gauge should be between 500 and 2500 PSI (3.45 MPa and 17.24 MPa) and the secondary gauge should be approximately 80 PSI (0.55 MPa). If either gauge is not in the proper range, alert the manager on duty of the nitro‐ gen level.

Cleaning Products

KAY-5® Cleaner/Sanitizer

Mix one 1 oz. (29.6 ml) packets of Kay‐5 ® Sanitizer/Cleaner solution (or similar brand) in

0.75 gallons (3 quarts) of tap water to insure 330 PPM of available chlorine.

Urnex Sani-Pure Sanitizer & Cleaner

Mix 3 oz. (88.7 ml) of Urnex Sani‐Pure Sanitizer & Cleaner solution (or similar brand), in 1 gallons (4 quarts) of tap water to insure 600 PPM of available chlorine.

IMPORTANT: Use tap water at 75‐95°F (23.89‐35°C). Water above this range breaks down the chlorine count and minimizes sanitation.
