1. Flush the water line and securely attach it to the inlet fi tting at the rear of the brewer.
2. Turn on the water supply.
PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with operating pressure between 20
and 90 psi (138 and 620 kPa) from a
1
⁄2" or larger supply line. A shut-off valve should be installed in
the line before the brewer. Install a regulator in the line when pressure is greater than 90 psi (620
kPa) to reduce it to 50 psi (345 kPa). The water inlet fi tting is
1
⁄4" fl are.
NOTE - Bunn-O-Matic recommends
1
⁄4" copper tubing for installations of less than 25 feet and
3
⁄8"
for more than 25 feet from the
1
⁄2" water supply line. A tight coil of copper tubing in the water line will
facilitate moving the brewer to clean the counter top. Bunn-O-Matic does not recommend the use of
a saddle valve to install the brewer. The size and shape of the hole made in the supply line by this
type of device may restrict water fl ow.
1. Insert an empty funnel into the funnel rails.
2. Place an empty server under the funnel.
3. Connect the brewer to the power source.
4. Turn on the main ON/OFF switch located on the
left side of brewer (If equipped).
5. Water will fl ow into the tank and stop when the tank
is fi lled to its capacity. Display will show "PLEASE
WAIT...TANK FILLING" until tank is fi lled with
water.
6. Wait approximately twenty minutes for the water
in the tank to heat to the proper temperature.
Display will show "READY TO BREW...WATER
TEMP: 200°" when tank is at operating tempera-
ture. Some water will drip from the funnel during
this time; this is due to expansion and should not
occur thereafter.
7. Place a small container beneath the faucet and
open the faucet handle. Release it when you hear
the tank refi lling.
8. Water volumes and fl ow settings have been preset
at the factory. Refer to adjustments for the Set
Brew Volumes section of this manual should the
volume need to be increased or decreased.
9. The brewer is now ready for use in accordance
with the instructions for Coffee Brewing.
10. Repeat steps 5-9 for remaining side on Twins.
