** CORRECT PROCEDURES FOR BREWING COFFEE AS RECOMMENDED BY THE COFFEE BREWING CENTER **
1. Use fresh urn grind or drip grind coffee . . . spread evenly on filter for proper extraction.
2. Urn should be connected to cold water supply and water heated to 197°-205°F (92°-96°C) before brewing coffee.
3. While brewing, leave cover on urn to preserve aroma and prevent excessive steaming. Total contact time for urn grind should be
approximately 4-6 minutes.
4. Remove grounds and filter as soon as coffee has dripped through. Never pour coffee back through spent grounds.
5a. Urns with automatic agitator (FE and INS series) blend coffee automatically at end of brewing cycle. Press and hold agitator ON switch
(31) for additional blending.
b. If urn has a manual agitator (CL series), press and hold agitator ON switch (31) for 15 seconds after brewing cycle to blend coffee.
c. On urns without agitator (CRS series), blend coffee by drawing off about half of batch and pouring back into brew (after removing
grounds and filter).
6. Hold coffee at 185°-190°F (85°-88°C) (about 8 on thermostat). Brewed coffee should not be held for longer than one (1) hour
and should never be reheated.
SOLID-STATE TIMER ADJUSTMENT (ALL FE's, INS's and CRS's): A factory pre-set electronic solid-state timer controls the volume of
water for each brew cycle. If more or less water is desired, follow these instructions:
Turn knob of timer (18, III.3) clockwise to increase volume of water or counterclockwise to decrease it. Run through a complete brew
cycle after each adjustment. Since timer cannot be readjusted in mid-cycle, simply push cycle stop switch (25) at bottom right of side
box if water gets too high. If maximum setting of timer fails to deliver enough water, check water pump and spray head and follow
instructions under maintenance.
NDTE: The FE200 features a dual timer. The upper knob is factory-adjusted for a 11b. brew, the lower knob for the full 2 Ib. brew.
MECHANICAL TIMER ADJUSTMENT (ALL CL's): The factory pre-set mechanical timer can be adjusted for more or less water by
following these instructions:
Remove timer knob and loosen lock nut holding stop pin. To increase volume of water, rotate stop pin clockwise. To decrease, rotate
counterclockwise. Tighten lock nut and replace knob.
SPRAY ARM BY-PASS ADJUSTMENT (ALL FE's, INS's, CL2DD and CRS661 (See III. 2).: Adjustable bypass allows proper brew
extraction even with variations caused by soft or treated water. If bypass requires adjustment to correct for local water conditions, proceed
as follows:
Position spray head over center of coffee liner and press BREW switch. Turn by-pass adjustment screw clockwise to decrease by-
pass flow (for stronger coffee) or counter-clockwise to increase it (for less strong coffee). At end of brewing cycle, note volume of
water in coffee liner. Readjust timer if necessary to obtain the correct volume of water.
THERMOSTAT ADJUSTMENT: To adjust temperature of water in urn jacket (205°F or 96°C), turn thermostat knob (33, III. 3) to 10
(maximum clockwise position). Pull off knob and insert a small screwdriver into adjusting screw in center of shaft when temperature on dial
thermometer (32) approaches the "W" in the word BREW. Slowly rotate screw clockwise until thermostat pilot light goes out. Turning screw
clockwise lowers temperature and turning counter-clockwise raises it. Apply a sealer (glyptol or fingernail polish) to screw after adjustment
has been made.
** MAINTENANCE TIPS **
SPRAY ARM ASSEMBLY: The new improved spray head system was designed to facilitate easier cleaning and maintenance. The swivel
valve has a larger flow opening and the spray head cap is equipped with a stainless steel disc, used to control the flow of water.
When ordering replacement parts, be sure to order the correct disc and spray cap for each urn, as shown in Illustration 2.
