INSTALLATION

WARNING: ELECTRIC SHOCK HAZARD! Installation of this appliance should be performed by qualified service personnel only. Improper installation could result in electrocution.

SET-UP AND POSITIONING OF BREWER

•Remove the brewer from packaging material and attach legs.

•Position the brewer on a strong, stable table or counter. Check the level front to back and side to side. Adjust legs as necessary to level the unit.

WATER AND ELECTRICAL CONNECTIONS

IMPORTANT:THE PERSON INSTALLING THIS APPLIANCE IS RESPONSIBLE FOR ENSURING THAT ELECTRIC AND WATER CONNECTIONS MEET THE REQUIREMENTS OF THE NATIONAL ELECTRICAL CODE, NATIONAL PLUMBING CODE AND ANY LOCAL ORDINANCES.

The water and electrical connection locations are behind the front panel on the right side of the brewer. Remove the screws fastening this panel to the unit to access these connections.

WATER HOOK-UP

•The water line may enter the brewer through holes in the bottom or rear of the brewer.

•Use 3/8” copper tubing or flexible water line to prevent strain. Do not use low temperature plastic tubing. The connection to the fill valve is 3/8” flare.

•Water line pressure should be between 30 and 70 psi.

•Hot (up to 160°F) or cold water may be supplied to the unit. Hotter water will allow faster recovery between brews.

ELECTRICAL POWER SUPPLY HOOK-UP

•The electric ratings for this brewer are printed on the nameplate attached to the unit. Always see the name plate for rating information for the particular brewer.

•The brewer should be connected to its own dedicated circuit with a fused disconnect switch or circuit breaker near the brewer.

•Attach the appropriately sized cord to the brewer with a cord grip for the 1-1/8” electric input opening in either the rear or bottom of the unit. Use an oil resistant cord such as type SO, SOO, SAO, STOO, SEO, SJO, SJOO, SJTO, SJTOO, SJEO, HSO, HSOO, HSJO or HSJOO. Alternatively, flexible conduit and type THHN wires may be used. Use only copper conductors.

•Standard units are single element units and are wired internally for single phase, 3 wire service. Connect the neutral line to the N terminal of the terminal block and the 2 conductors to L1 and L2 of the terminal block. 3 element units may be connected to single or 3-phase service. 3 element, single-phase units should be connected as described above. For 3 element units intended to operate with a 3 phase power supply, connect the third phase conductor to L3 of the terminal block.

•The body of the brewer must be grounded. Connect the ground conductor to the ground lug located near the terminal block.

WARNING: ELECTRIC SHOCK HAZARD! Never use the ground conductor as a neutral. This could cause electrocution.

INITIAL START-UP

•Turn on the water supply to the brewer. Check for leaks at the supply line to fill valve connection. Remove the controller cover panel.

•Turn on the electrical power. The brewer will begin to fill. Units that require more than 5 min. to fill will display an error message “ER1” on the controller after 5 min. of filling. Press the SELECT button on the controller for 10 sec. to reset the unit and continue filling. To reset the controller, the SELECT button must be pressed while the LED’s indicate ER1. If the SELECT button is momentarily pressed a timer numerical value will be displayed. If this occurs, wait 10 sec. and the error message will again be displayed; press the SELECT button for 10 sec. to reset controller and resume filling.

•After the tank has filled, replace the controller cover panel.

•Turn on power and the water heating cycle will begin; it will take 15-35 min. to complete the heating cycle. The WATER HOT light on the front of the unit will turn on when the water has reached temperature.

•The brewer can now be operated to evaluate brew timer settings and then make adjustments as necessary. The brewer timers settings are preset at the factory to the following values:

Small brew

(0.75 gal.)

120 sec.

Medium brew

(1.25 gal.)

165 sec.

Large brew

(1.75 gal.)

230 sec.

•Insert the brew baskets and place the appropriate container under the brew basket.

•Portion size is selected with the touchpad located on the front of the brewer. The upper right hand area of the touchpad has 2 LEDs. If both are lit the unit is set to brew the large volume. If only the upper LED is lit, the brewer will brew the medium volume; if only the lower LED is lit, the brewer will brew the small brew volume.
