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 (1116th 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.
   | WARNING – This product can expose you to chemicals including Acrylamide and Bisphenol A (BPA), which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information visit www.P65Warnings.ca.gov.
   ---|---
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 Settingthe 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 W 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.

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 psi, 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.
