  • Page 5: Installation

    Here are the key points to consider before installation: Electrical: All FETCO brewers require NEUTRAL. Ground is not an acceptable substitute. Installation without neutral may cause damage to the electronic components. The electronic controls require at least 105 volts. Less than 105 volts will cause erratic behavior from the brewer.
  • Page 6 Electrical Connection 1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the brewer’s serial number label. Make sure the electrical service includes neutral. 2. The temperature and water tank fill level are pre-set at the factory. There is no need to turn off the heaters during the installation process.
  • Page 7: Operating Procedures

    1. Turn the power switch • The power switch will illuminate to indicate that the brewer has power and is operating. • When the ready light required to gain full operating temperature will vary depending on the electrical configuration that was ordered, and the temperature of the incoming water.
  • Page 8: Service

    Service Warranty All FETCO brewers come with a limited warranty. All warranty service must be pre-authorized by calling the FETCO Service Department at (800) 338-2699. Principles of Operation Fill System The fill system consists of a liquid level control board, a water level probe at the top of the tank, and a fill valve. As the water rises and touches the probe, continuity is established between the probe tip and the tank body, and the fill valve closes.
  • Page 9: Adjustments

    Adjustments Thermostat Adjustment: For equipment manufactured before April 2004 The brewer’s water tank temperature is factory set at 203°F (slightly lower for high altitudes, to prevent boiling). This setting will deliver water at 195°F ± 5° to the coffee grounds. Measure the temperature by holding a thermometer in the stream of water flowing out of the hot water faucet.
  • Page 10: Timer Adjustment

    Timer Adjustment: For equipment manufactured before April 2004 The timers control the amount of water that is used for brewing. The dual sided brewer, (CBS-32A, & 32Aap) has separate timers to control each side independently. All timers are factory set to deliver the correct amount of water. There are three possible types of timers used: •...
