INITIAL SETUP - SRU
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.
8. When the desired temperature is attained, place the funnel support, funnel, and funnel cover on top of the
coffee reservoir. Center the discharge of the water swing spout over the opening in the top of the funnel
cover.
9. Place the lighted ON/OFF switch in the "ON" position and momentarily press and release the start switch.
Water should flow from the swing spout into the funnel assembly.
10. Drain and measure the water from the reservoir when the flow of water from this initial cycle stops. If it is
three gallons, proceed to step 12. If it is more or less than three gallons, proceed to step 11.
11. Adjust the brew timer as required. See Adjusting Brew Volumes. Repeat steps 9 & 10.
12. The brewer is now properly adjusted to brew coffee.
Bunn-O-Matic recommends a bead of silicon sealant be placed around the base on the countertop
after the initial operation instructions are completed. B.O.M. #M2509.1001 sealant is available.
