PLUMBING REQUIREMENTS

Hot Water Rinse Connection

Hose assembly to be

replaced after Hot Water Rinse

Hot Water Connection (See Caution)

Install Cap with Hot Water Connection

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100 psi (138

and 690 kPa). This water source must be capable of producing a minimum ﬂow rate of 3 ﬂuid ounces (88.7 milliliters) per second. A shut off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). Also if the install location experiences pressure ﬂuctuations greater than 20 psi (138kPa). The main water inlet is a 3/8” (9.52 mm) male ﬂare. Additionally, the dispenser’s rinse connection may be connected to a HOT WATER system.

Caution: MAXIMUM RINSE WATER TEMPERATURE: 170 degrees F (76.6 degrees C)

Use BUNN-O-MATIC tubing, part number 34325.10_ _ (see Illustrated Parts Catalog for complete part number) for hot water connection. The rinse water operating pressure must be between 20 and 100 psi (138 and 690 kPa). A shut off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). The rinse water inlet is a 3/8” (9.52 mm) barb connection. NOTE- At least 18 inches (457 mm) of an FDA approved ﬂexible beverage tubing, such as reinforced braided polyethylene, before the dispenser will facilitate movement to clean the countertop. It can be purchased direct from BUNN-O-MATIC (part number 34325.10_ _ [see Illustrated Parts Catalog for complete part number.]) BUNN-O-MATIC does not recommend the use of saddle valves to install the dispenser. The size and shape of the hole(s) made in the supply line(s) by saddle valves may restrict water ﬂow. NOTE- On early models dispensers without water inlet valve, a water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the ﬂexible water line. This strainer is supplied loose with the dispenser. 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.

This equipment must be installed to comply with the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models installed outside the U.S.A., you must comply with the applicable Plumbing/Sanitation Code for your area.

PLUMBING HOOKUP CAUTION: The dispenser must be disconnected

from the power source throughout the plumbing hookup. For early models without the water inlet valve, plumbing connections are located behind the dispenser’s splash panel. Hoses are connected to the water valve(s) and travel under the water bath tank and out the rear of the dispenser. A .38" female ﬂare connector is attached to the hose and connects to the supplied water strainer. The water strainer is shipped loose, taped to the bottom panel. For late models with the water inlet valve, a hose assembly from the water bath shut-off valve travels over the top of the water bath tank to the product coil and the water inlet valve. A .75" hose to .38" male ﬂare ﬁtting attaches to the water inlet valve. To access the water valves in the front of the dispenser, remove the drip tray assembly; remove

INITIAL FILL

CAUTION: The dispenser must be disconnected from the power source throughout the initial ﬁll except when

speciﬁed in the instructions.

1. Remove drip tray assembly and splash panel from the dispenser. Set the drip tray back into place.

2. Ensure that the Main Water Valve (Early models) and the Water Bath Valve Fig 3, are turned off (handles positioned at 3 o’clock and 9 o’clock, respectively,) and that the Refrigeration Switch Fig 2, is in the OFF (rear) position.

3. Turn on the water supply.

4. Connect the dispenser to the power source.

5. For late models with the water inlet valve, simultaneously press the two hidden switches (C, Figs 4 & 5) to enter the program mode. This activates the water inlet valve at the rear of the dispenser and allows water to ﬂow to the water bath valve at the front of the dispenser.

6. While observing the water bath sight gauge (the clear tube located just to the left of the plumbing connections,) begin ﬁlling the water bath by rotating the handle of the Water Bath Valve counterclockwise to the 6 o’clock position. The dispenser will beep for three seconds when the bath is approaching full. Reduce the ﬂow rate at this time.

7. When the water level in the sight gauge comes within 1 inch (25.4 mm) of the clear plastic tee, reduce the water ﬂow by rotating the handle of the Water Bath Valve clockwise to the 8 o’clock position.

8. When the water in the water bath sight gauge begins to trickle down into the drip tray, turn the Water Bath Valve off by rotating the handle clockwise to the 9 o’clock position.

9. After approximately 3 minutes (this allows the recirculating pump and cabinet cooling components an opportunity to ﬁll with water,) top off the water bath tank by rotating the handle of the Water Bath Valve counterclockwise to the 8 o’clock position.

10. Again, when the water in the water bath sight gauge begins to trickle down into the drip tray, turn the Water Bath Valve off by rotating the handle clockwise to the 9 o’clock position.

11. Place the Refrigeration Switch ON (forward.)

12. It will take approximately 4 hours at 70 degrees F (21 degrees C) ambient to create the ice bank required for full dispenser performance. During this time, some further trickling from the water bath is expected due to expansion caused by ice bank formation. While the refrigeration system is creating the ice bank, the dispenser may be readied for use as described in Loading, Priming and Adjustment.

13. The dispenser will safely store concentrate once the “COOLING” indicator completely extinguishes (not lit steadily or ﬂashing.)

14. For early models, after the refrigeration compressor switches off, turn Main Water Valve on by rotating the handle counterclockwise to the 12 o’clock position.

15. Replace the splash panel and drip tray assembly.

LOADING Frozen Concentrates

1. Thaw the frozen concentrate in a refrigerated 35-40 degrees F (1.6-4.4 degrees C) environment for 36 to 48 hours before use.

2. Thoroughly mix the thawed concentrate by vigorously shaking the product container.

3. Open the dispenser door.

4. Prior to placing the product container in the dispenser, make sure that the o-ring on the container adapter is lubricated. This will ease removal of the container when it becomes necessary.

5. Place the product container in the desired position and press it ﬁrmly into the bottle adapter opening.

6. Open the vent hole in the product container.

Note: Concentrate in the container must be completely thawed and be within the temperature range of 35-40

degrees F (1.6-4.4 degrees C.) Product outside of this temperature range, especially below, will produce an “out of brix” drink.

38218.1 030306

INITIAL FILL (cont)
