Site Requirements; Counter Top Installation; Location Of Serial Number; Initial Setup Plumbing - Bunn Sure Immersion 312 Installation & Operating Manual

The brewer must be disconnected from the power source until specified in Initial Setup. Refer to Data Plate
on the Brewer, and local/national electrical codes to determine circuit requirements.
• Unplug the machine or turn off the main switch before servicing the interior components of the machine.
• Never operate the machine without water.
• Never touch brew module, spouts, and hot water dispense pipes. They are HOT and could cause burns.
• The machine must be operated with clean water. Make sure to use water filters and/or softeners as needed.

Counter Top Installation

1. Remove tape from all five legs.
2. From the parts box, install a 03996.0000 foot pad
on each leg.
NOTE: For through counter grounds disposal,
the rubber feet must be installed on the bottom
of the legs to ensure alignment between the
ground, chute and counter top opening.
Counter Requirements
1. Counter able to support at least 200 pounds (90kg).
2. Counter area large enough for machine.
3. Minimum clearance of 2˝ around machine.
4. Machine must be level within 2˚ for proper operation.
Plumbing
1. These brewers must be connected to a cold
water system with operating pressure between
20 and 90 psi (0.138 and 0.620 MPa) from a 1/4"
or larger supply line. Install a regulator in the line
when pressure is greater than 90 psi (0.620 MPa)
to reduce it to 50 psi (0.345 MPa).
2. Shut off valve should be present between water
supply and machine.
3. Flush the water line and securely attach it to the
inlet fitting at the rear of the brewer.
4. Turn on the water supply.
5. Check for leaks.
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 sup-
ply 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.

Water Treatment

1. No Chlorine, no chloramines
2. Water Hardness 6 to 10 grains (total hardness)
3. Water Filtration System
