PLUMBING REQUIREMENTS

The dispenser may be connected to a cold or hot water system (140°F Max.) 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 3/8” flare. Dispensers set up to deliver to 1.8 Oz./sec. (53.2 ml/sec) per dispense tip, require a water supply source that can deliver a minimum of 1.7 gpm (6.4 lpm) at the inlet fitting. Dispensers set up to deliver 2.6 Oz./sec. (76.9 lpm) per dispense tip, require a water supply source that can deliver a minimum of 2.4 gpm (9.2 lpm) at the inlet fitting.

NOTE: Bunn-O-Matic recommends 3/8” tubing from the 1/2” water supply line. At least 18 inches of FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the counter top. 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.

ELECTRICAL HOOK-UP

CAUTION: Improper electrical installation will damage electronic components.

1.An electrician must provide electrical service as specified in conformance with all local, state and federal electrical codes.

2.Using a voltmeter, check the voltage and color-coding of each conductor at the electrical source.

3.Connect the dispenser to the power source.

4.If plumbing is to be hooked up later, be sure the dispenser is disconnected from the power source. If plumbing has been hooked up, the dispenser is ready for Initial Fill & Heat.

PLUMBING HOOK-UP

1.Flush the water line to remove any debris or foreign material.

2.Securely attach the water line to the 3/8” flare fitting, on bottom right side of the dispenser.

3.Turn on the water supply and check for leaks.

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.
