INITIAL FILL & HEAT
CAUTION - The dispenser must be disconnected from the power source throughout the initial set-up, except
when specified in the instructions.
1. Turn-on the water supply and connect the dispenser to the power source.
2. Water will automatically flow into the tank to the proper level and then shut-off. This will take less than five
minutes.
3. When the tank is full of water, open the front door and place the heater switch in the “ON” (lower) position.
A tank full of cold water will take approximately forty minutes for the water to heat on 120 volt versions or
twenty minutes for 120/208 volt versions, 120/240 volt versions and 220-240 volt versions.
During this waiting period, complete these dispenser set-up steps:
a. Place the drip tray in front of the dispenser. Set the drip tray cover in place.
b. Place a set of keyholes in the cup locator plate over the screws beneath the hopper access door and push
down gently.
c. Fill the hopper with the dry product to be dispensed.

3. Turn-on the water supply.
PLUMBING HOOK-UP (Late Models)

PLUMBING REQUIREMENTS
This dispenser 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
dispenser. 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 fitting is
1
⁄
4
” flare.
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. At least 18 inches of an FDA approved flexible beverage tubing, such as
reinforced braided polyethylene or silicone, before the brewer will facilitate movement to clean the countertop.
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 flow.
NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed
and maintained in accordance with federal, state and local codes.
As directed in the International Plumbing Code of the International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate
backflow prevention to comply with federal, state and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.
PRESET TANK TEMPERATURE
Tank temperatures have been preset at the factory to 180°F (82°C). Bunn recommends that to provide the best
quality beverage, the installer adjust the tank temperature to the powder product manufacturer’s recommended
temperature for the hot powder product being used.
