PLUMBING REQUIREMENTS
This brewer must be connected to a cold water system with operating pressure between 20 and 90 psi (138
and 620 kPa) with a minimum of 4.0 gpm 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 fitting is 3⁄8" flare.
NOTE - Bunn-O-Matic recommends 3⁄8" copper tubing for all installations 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 flow.
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.
PLUMBING HOOK UP
NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between
backflow preventer and dispenser. Installing the shock arrestor as close to dispenser as possible
will provide best results.
1. Remove the shipping cap from the fitting on the bottom of the brewer.
2. Attach the flare tube assembly (supplied separately with the brewer) to the fitting using the
copper flare gaskets on each end as shown in illustration.

CLEANING
1. The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment. Do NOT clean this equipment with a water jet device.
2. Check and clean each sprayhead. The sprayhead holes must always remain open.
NOTE: Any buildup on the sprayhead may restrict water flow, and impact your coffee brewing. For consis-
tently great coffee, clean sprayheads weekly. Upon visual inspection it may appear that light passes through
all holes in the sprayhead plate, but a thin film of residue can pass light and still impede water flow.
3. Remove sprayhead from brewer. Disassemble by removing the seal.
4. Use the pointed end of sprayhead cleaning tool to remove any mineral deposits from the sprayhead holes.
5. Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times to remove
any mineral deposits from the fitting.
6. Insert the short end of sprayhead cleaning tool into the bypass fittings, and rotate several times to remove
any mineral deposits from the fitting.
7. Reassemble sprayhead and reattach. Sprayhead only needs to be hand tightened.
verify sprayhead flow rate matches programmed flow rate. Brewer may need to be re-calibrated due to lime
build up. If brewer is cleaned and build up removed, brewer must be re-calibrated to achieve desired volumes.
