Initial Setup - Sru - Bunn U3 Installation And Operating Manual

4. Turn the thermostat knob clockwise to an approximate 5 o'clock position. Allow 1-1/2 hours for water to heat. Time
will vary with incoming water temperature.
5. On initial warm-up, some water may flow thru the overflow spigot due to expansion of the cold water in the tank.
This will not recur during the use of the brewer and may be avoided on the initial warm-up by drawing off 1/2 gallon
decanters of water each 15 minutes till brewing temperature is reached.
6. Brewing cycles may be started whenever water temperature is correct. This condition is indicated by the dial
thermometer on front of the brewer. Whenever the pointer is in the green, brewer is ready for brewing. The
recommended brewing temperature is approximately 200
turning thermostat knob clockwise, decreased by turning knob counterclockwise.
7. When desired temperature is reached, insert funnel support, funnel and funnel cover in position. Be sure
the water swing spout is over the center of the funnel cover, turn "ON/OFF" switch to the "ON" position, push
and release "START" and run a brew cycle of hot water only. At the end of this cycle, brewer will be ready for
checking timer adjustment.
8. The timer has been preset for a 4 minute cycle. This setting will deliver approximately 3 gallons of water per
brewing cycle. To increase or decrease amount of water, adjust the timer as required. See Adjusting Brew
Volumes.
9. Having determined final settings of the thermostat and the timer, replace front cupola cover. Brewer is now
ready for brewing coffee.
CAUTION - The brewer must be disconnected from the power source throughout the initial setup, except when
specified in the instructions.
IMPORTANT: Brewer must be level and installed on a sturdy structure.
Electrician's and Plumber's Instructions are provided. These instructions should be carefully
followed before proceeding with initial setup.
Be sure all electrical and plumbing connections are tight.
1. Disconnect the brewer from the power source.
2. Remove the left side panel from the hood and rotate the control thermostat knob fully counterclockwise to
the "OFF" position. Replace the side panel.
3. Connect the brewer to the power source and place the lighted ON/OFF switch in the "ON" position. Water will
flow into the tank and should automatically stop after approximately 15 minutes.
NOTE - The lighted ON/OFF switch must be in the "ON" position to automatically refill the tank. The switch should
be in the "OFF" position whenever the brewer is left unattended.
4. Disconnect the brewer from the power source.
5. Remove the left side panel from the hood and rotate the control thermostat knob clockwise to the 5 o'clock
position. Replace the side panel.
6. Connect the brewer to the power source and wait for the water in the tank to heat to the proper temperature.
This will take approximately 1-2 hours, depending on the incoming water temperature. Some water will flow
from the overflow tube during this time due to expansion. Draw off a 1/2 gallon of water every 15 minutes
during the initial heat-up to lessen the chance of hot water flow from this expansion.
7. Determine the water temperature by checking the water with a thermometer at the hot water faucet (red
handle). The best brewing temperature is between 195˚ (91˚C) and 200˚F (93˚C). The temperature may be
increased by turning the thermostat knob clockwise and decreased by turning the knob counterclockwise.
