Installation Instructions
Installation Requirements

• A water filtration system is required to maintain trouble-free operation. Wilbur Curtis Co., Inc. recommends a Wilbur Curtis approved water filter. See the Curtis Equipment Catalog for a full line of Wilbur Curtis approved water filters.
• Potable water supply line connection from the water filter capable of supplying the minimum flow rate required by the specifications. The water supply line must be able to connect to the flare fitting on the back of the unit. See the SPECIFICATIONS section for the correct size. The water line should also be capable of being controlled by a shut off valve. Do not connect the water line to a saddle valve or needle valve.

NSF International requires the following water connection:

1. A quick disconnect or additional coiled tubing (at least two times the depth of the unit) is required so that it can be moved for cleaning underneath.
2. This equipment is to be installed with adequate back-flow protection to comply with applicable federal, state and local codes.
3. Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed and maintained in accordance with federal, state and local codes.

The International Plumbing Code of the International Code Council and the Food and Drug Administration (FDA) Food Code manual, direct that this equipment must be installed with adequate back-flow prevention in compliance with federal, state and local codes. For units installed outside of the U.S.A., make sure that the installation is in compliance with the applicable plumbing/sanitation code for your area.

1. Position the unit on a level counter too capable of supporting its operating weight. See the SPECIFICATIONS section.
   Connect the Water Supply

2. Make sure that the water supply valve on the back of the unit is in the OFF position.

3. Flush the water supply line before connecting It to the unit to purge air and debris from the water filter and tubing.

4. Connect the water supply line to the flare fitting on the back of the unit.

5. Open the water supply valve running to the unit. Also, turn the valve handle on the back of the unit itself to the ON position.

6. Sanitize the dispensing system according to the instructions in the CLEANING INSTRUCTIONS section before using the unit for the first time. While flushing out the system, check the connections on the incoming water line for leaks.

OPERATING INSTRUCTIONS

Use Instructions
WARNING – DO NOT refrigerate unused tea overnight for later consumption. Never hold dispensed tea for more than eight hours at room temperature. Discard any unused tea after eight hours.
NOTICE – Curtis strongly recommends that the water supply valve, behind the unit, be turned off during non-business hours.

The liquid concentrate tea/coffee dispenser is factory preset for optimal performance.

1. Make sure that the appropriate liquid concentrate bag(s) are connected to the unit. See the instructions below.

2. The main water supply and the water valve on the back of the unit should both be in the on position.

3. Hold a cup under the faucet and pull forward on the handle to dispense.

Changing/Attaching the Liquid Concentrate Bag
Reload the concentrate bag and re-prime the unit immediately when the bag is empty.

| |
---|---|---
1 Remove the top cover from the TCC dispenser and pull the empty concentrate bag and hose out.| 2 On units with a Scholle type connector, unscrew the connector from the bag and pull it up and off.| 3 On units with a QCD type connector, release it by pulling up on the hose
and cap assembly on the opposite sides. The plunger will pop up in the center of the QCD. Slide sideways to remove.
| |
---|---|---
4 Place the new tea/coffee concentrate bag on the counter next to the TCC dispenser. Remove the shipping cap on the spout.| 5 On units equipped with a Scholle type connector, place the connector over the
bag spout and thread the connector all the way into the spout. Skip to step 8.| 6 On units with a QCD connector, place the QCD next to the spout, then
slide sideways until it stops.

7 Push in on the QCD plunger until it snaps into place.

8 Carefully lift the bag and set it inside the dispenser. Rest the tubing on top of the bag. Route the tubing to the opposite product intake hole on the floor of dispenser, as shown.

9 Replace the top cover and dispense beverage from each faucet until darker product starts to appear (approximately 5 to 10 seconds).

Mixing Valve Adjustment

1. Usually, the factory settings do not require adjustment. However, for customers who wish to adjust the flavor of the drink, the mixing valve changes the water to concentrate ratio. This valve is very sensitive. Only slight rotation of the mixing rod is needed to change the ratio (1/16th to 1/8th of a turn). The factory setting Is approximately 7:1 ratio, which will result in a 5 to 8 percent brix when sweet tea concentrate is used.
   NOTICE – Do not rotate the adjusting rod more than 2 full turns from the closed position. More turns will cause the adjustment rod to disengage from the mixing valve, resulting in a leak.

2. Tilt the dispenser on its side.

3. Before adjusting the mixing valve, check to make sure that the pressure regulator is set to 15 psi. If the regulator is not properly set, the mixing valve will not work properly. See Setting the Pressure Regulator for instructions.

4. Locate the adjusting rod (see diagram below). Turn it counter-clockwise (looking from the bottom) for a stronger concentration — turn clockwise for a weaker concentration. Taste the tea/coffee with each adjustment to determine the desired consistency.

Setting the Pressure Regulator
NOTICE – Do not exceed 25 psi (static). Equipment failure or leakage will result.

IMPORTANT – Do not use the pressure regulator alone to adjust the taste/brix level. Confirm that the regulator is properly set, then adjust the taste/brix level using the Mixing Valve Adjustment instructions.

The purpose of the regulator is to provide uniform water pressure, so that the mixing valve can produce a stable and uniform blend of concentrate and water, and also to protect the hydraulics of the dispensing unit from excessive line pressure.

1. Tilt the dispenser on its side.
2. Locate the regulator adjustment knob and turn it until the pressure level on the gauge reads 15 psi.

CLEANING INSTRUCTIONS

NOTICE – Do not use cleaning liquids, compounds or powders containing chlorine (bleach) or corrosives.
These products promote corrosion and will damage the finishes. USE OF THESE PRODUCTS WILL VOID THE WARRANTY. Do not immerse the unit in water or any other liquid.

Daily Cleaning

1. Prepare a mild cleaning solution of dish-washing detergent and warm water.

2. Wipe any spills, dust or debris from the exterior surfaces, with a damp cloth. Apply a stainless steel polish to prevent scratches.

3. Turn off the water supply at the valve behind the unit.

4. Open the faucet to relieve pressure in the system lines.

5. Remove the top cover and clean with the detergent solution.

6. Clean the faucet assembly:
   • Remove the handle/seat cup assembly from the faucet by holding the bonnet and unscrewing.
   • Inspect the seat cup. Replace if torn or damaged.
   • Clean the bonnet and silicone seat cup.
   • Use a spiral brush soaked in cleaning solution to clean inside the faucet body.

7. Rinse and dry parts that were removed. Assemble the dry parts onto the unit.

Weekly Cleaning and Sanitizing

The following cleaning process requires a mild solution of dish-washing detergent and warm water for washing, and for sanitizing, One-Pro Beverage Equipment Cleaner (Curtis PN WC-79001) or BevClean Bag-in-Box (BIB) type cleaning solution. Note: For BevClean BIB solution, multi-outlet manifolds are available for sanitizing up to eight beverage lines at one time.

1. Turn on the water supply to the dispenser.

2. Remove the QCD (quick disconnect) from each concentrate bag.

3. Pull the cap off of the QCD(s) and place in a bucket containing the mild detergent solution.

4. Place alarge empty container under the faucet.

5. Open the faucet and dispense until only the detergent solution is being dispensed. Repeat for additional faucets.

6. Allow the dispenser to sit for 20 minutes before proceeding to step 7.

7. Flush the system by placing the QCD(s) in a bucket filled with clean hot water (no detergent solution). Open the faucet(s) until all the detergent solution has been flushed from all the lines in the system.

8. Remove the QCD(s) from the bucket. If using BevClean BIB sanitizer, replace the QCD cap(s).
   Sanitizing

9. Setup for the sanitizing process: : If using BevClean, place the BIB sanitizer container(s) next to the TCC dispenser (one for each faucet). Pull the spout from the sanitizer BIB through the marked area. Remove the protective cap from the spout. Since the BIB has an inner seal the cap can be removed without spillage. Snap the QCD onto the bag spout(s) and push the plunger on the end in until it clicks into place.
   If using One-Pro Beverage Equipment Cleaner, mix 1 oz. (28 g.) of cleaner in a 5 gal. (19 L) bucket of hot water (122°F/50°C min.).

10. With an empty container underneath, open the faucets and allow liquid to flow until sanitizer (clear liquid) Is flowing.
    DO NOT FLUSH. Allow the sanitizing solution to sit in the system lines overnight before proceeding with the line flushing steps below.

11. Flush the sanitizer out of the unit:
    If using BevClean, remove the QCD(s) from the BevClean BIB and reattach the concentrated BIB product. Open the faucet(s) and allow fluid to run out until mixed beverage flows from each faucet.
    If using One-Pro cleaner, flush out the system by placing the QCD(s) in a bucket filled with clean hot water (no cleaning solution). Open the faucet(s) and flush the lines until 2 gal. (8 L) of water has been flushed through each line. Remove the QCD(s) from the bucket and replace the QCD cap(s). Reattach the concentrated BIB product. Open the dispensing faucet(s) in front of the dispenser and allow fluid to run out until mixed beverage flows from each faucet.|

TROUBLESHOOTING GUIDE

Troubleshooting Guidelines
This troubleshooting guide identifies some, but not all, of the possible causes for common problems that can Occur.

Nothing Comes Out of the Faucet

1. Check to make sure that both the water supply valve for the water supply line and the valve on the back of the unit are turned on.
2. Check for a clogged water supply filter.

Only Water Flows from the Faucet, Not Tea/Coffee

1. Check to make sure that the concentrate bag is not empty.
2. Check to make sure that the concentrate supply hose is not kinked or blocked. Trace the hose all the way from the concentrate bag to the mixing valve.
3. Check to make sure that the mixing valve is not completely closed. If it is, turn it 1/4 counter-clockwise (looking from the bottom of the unit).
4. Check to see if the check valve in the concentrate line is stuck closed.

Tea/Coffee is Weak

1. Check to see if the mixing valve is out of adjustment. See Mixing Valve Adjustment in the OPERATING INSTRUCTIONS.
2. Check to see if the check valve in the concentrate line is stuck closed. Check to make sure that the valve is installed in the correct orientation (arrow must point in direction of flow).

Tea/Coffee Coming from the Faucet is Foamy or Bubbly

1. Make sure all air is purged from the concentrate bag.
2. Check the O-ring/gasket on the concentrate bag connector. A worn out O-ring/gasket can allow air to be sucked into the hose.
3. Check for lose clamps on the concentrate hose. All clamps must be tight. Check all of the clamps tracing from the concentrate bag to the mixing valve.

Faucet Drips Constantly

1. Check for a worn or dirty faucet seat cup. See CLEANING INSTRUCTIONS.
2. Check to make sure that the pressure regulator is set to 15 psi. If the regulator cannot be adjusted down to 15 posi, check to make sure that the incoming pressure does not exceed 90 psi. If it does, an external pressure regulator may be required to lower the incoming pressure. If the pressure going into the regulator is within specifications (less than 90 psi), but cannot be adjusted down to 15 psi, the regulator is probably defective.
