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- A water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the flex- ible water line. This strainer is supplied loose with the dispenser. (See Fig. 2 for proper locations)

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.

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.

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.

2.Pull the overflow tube from its retaining clip and connect it to the main water source (black gasket is supplied in install kit).

3.Connect dispenser to the power source.

4.Slowly open the water shut off valve and fill the water bath until water trickles from the overflow. The dispenser will beep for three seconds when bath is approaching full. Reduce the flow rate at this time.

5.After 3 minutes of power, slowly add more water to the tank until water trickles from overflow again.

6.Once water bath is filled, remove water source, cap dispenser fill line, and store the fill tube in it’s holder (the fill tube can now be used as a sight glass).

7.Replace the splash panel and drip tray.

8.Place refrigeration switch to the “ON” position. It will take approximately three hours at 75° F (24° 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 Plumbing, Loading, Priming and Adjustment.
