Plumbing Requirements, Plumbing HOOK-UP

PLUMBING REQUIREMENTS

This dispenser must be connected to a cold water system with operating pressure between 20 and 90 psi (138 to 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 (690 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 dispenser will facilitate movement to clean the countertop. Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. 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.

NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between backflow pre- venter and dispenser. Installing the shock arrestor as close to the dispenser as possible will provide the best results.

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.

PLUMBING HOOK-UP

1.Flush the water line and securely attach it to the elbow fitting on the bottom of the dispenser.

2.Turn on the water supply.

INITIAL FILL & HEAT

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 ten minutes.

3.When the tank is full of water, open the front door and place the ON/OFF/NIGHT switch in the “ON” (upper) position. A tank full of cold water will take approximately eighty minutes for the water to heat on 120 volt versions, and forty minutes on 120/240 volt and 220-240 volt versions.

4.Fill the hopper(s) with the dry product to be dispensed.

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 recom- mended temperature for the hot powder product being used.

LIQUID LEVEL CONTROL

The system automatically maintains the hot water tank’s level by energizing the refill solenoid when the water level drops below the liquid level probe. If the system has not successfully refilled in 10 minutes, a refill error occurs. When a refill error occurs, the refill solenoid is de-energized. Once the cause of the refill error has been investigated and cured, the system can be reset by either disconnecting (for at least 5 seconds) and then reconnecting the power to the machine, or by entering one of the program modes (see Programming Modes.)
