TIMER ADJUSTMENT

The amount of water dispensed automatically during a brew cycle is controlled by the timer.

Place empty decanter under brew chamber. Press BREW button. Brewer should dispense one decanter of water. To adjust amount:

Remove brew chamber and button plug. Adjust knob on timer; clockwise increases time. Run several cycles to check amount of water delivered. Replace button plug.

REMOVE TANK LID ASSEMBLY

Unplug brewer or turn circuit breaker OFF. Turn OFF water supply. Remove top panel. Pull vent tube and inlet elbow out of basin pan.

Pull water inlet tube out of basin pan. Remove basin pan.

On models with faucet, disconnect inlet pipe at faucet shut-off valve and outlet pipe at faucet.

Disconnect all wiring from thermostat, hi-limit, and heating element.

IMPORTANT: Water pressure must be between 20 p.s.i and 90 p.s.i. flowing pressure.

If water pressure exceeds this value, or if water pressure varies greatly, a pressure regulator must be installed in the water supply line.

IMPORTANT: Before setting assembly into tank, make sure tank lid gasket is properly seated on flange of lid.

DO NOT OVER-TIGHTEN.

IMPORTANT: When mounting thermostat, be sure a new seal washer is placed below the fitting on the capillary line. Push sensing bulb thru tank lid until fitting seats.

Tighten capillary lock nut only enough to ensure no water leakage. Excessive tightening is not necessary.
