INITIAL OPERATION INSTRUCTIONS
IMPORTANT: • Brewer must be level or slightly lower
f'n
front to siphon properly.
• Electrician's and Plumber's instructions are provided on page 2. These instructions
should be carefully followed before proceeding with initial operation instructions.
• Be sure all electrical and plumbing connections are tight.
NOTE: Be sure thermostat is in OFF position.
Turn power to brewer ON.
Place brewing funnel in proper position for brewing. Place a decanter containing a little water on
center warmer and turn ON-OFF toggle switch to the ON position. This switch must be ON to operate
a brew cycle. _
Deflect the start switch. This will start a brew cycle and allow water to flow into the tank. Water will
run approximately two minutes before timed cycle ends. Repeat this cycle three additional times;
water should overflow tank into the decanter on center warmer during the fourth cycle.
Turn power to brewer OFF. Remove front panel via two screws. Adjust timer to deliver desired amount
of water. To increase amount of water, increase time of water flow by turning timer dial slightly
clockwise. To decrease amount of water, decrease time of water flow by turning timer dial slightly
counterclockwise.
6. Turn control thermostat knob fully clockwise to the ON position. Turn power to brewer ON and allow
approximately 10 to 20 minutes for water in tank to heat. (F-35 approximately 10 minutes-F-20 ap-
proximately 15 minutes-F-15 approximately 20 minutes.) When the water reaches brewing
temperature, the contronhermostat will click off and the heating noise will stop. On initial heat up,
normal water expansion will occur in the water tank. Water may drip from the funnel due to this ex-
pansion, but will not occur thereafter.
7. Turn on-off switch to the ON position. Place empty decanter on center warmer under the funnel and
deflect start switch. Run a partial cycle to remove expanded water from the tank. Now run a full cycle
to check for proper timer setting and to cycle control thermostat.
8. When control thermostat clicks off and heating noise stops, run a cycle to check for proper
temperature setting. With an accurate thermometer, take the temperature of the water at the point
below the funnel opening and at the time when the decanter is about half full. Recommended
temperature of the water is approximately
1950
F. Due to higher altitude locations (5,000 ft. above sea
level) thermostat may have to be readjusted to prevent boiling.
9. If water volume and temperature are correct, replace front panel. Coffee brewer is now ready for brew-
ing coffee.

CLEANING TIPS
1. For cleaning all metal surfaces, use any reputable stainless steel cleansing compound.
2. Sprayhead should be checked and cleaned regularly. (At least once a week.) Sprayhead holes must be
kept open.
3. To prevent "LIMING" problems in the water tube and air tube, remove sprayhead and insert deliming
spring all the way into the tank through both tubes. When inserted into tank properly, no mora than
two inches of the spring should be visible. Saw back and forth five or six times. This will keep tubes
open and clear of lime. In hard water areas this should be done every day; this takes less than a
minute.
