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 po-
sitioned 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 connec-
tions,) 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 op-
portunity to fill with water,) top off the water bath tank by rotating the handle of the Water Bath Valve coun-
terclockwise 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.
