kg). The FCD-4 i de igned for indoor u e only.
1. Set the di pen er on the counter where it will be u ed. The
FCD-4 require a minimum of 4 inche (102 mm) of air
clearance at the rear and 8 inche (203 mm) of air clear-
ance above the di pen er. Minimal clearance i required
between the di pen er ide and the wall or another appli-
ance. For optimum performance, do not let warm air from
urrounding machine blow on the FCD-4. Leave ome
pace o the di pen er can be moved for cleaning.
2. A emble the cup top in the third lot of the drip tray
cover a hown in Fig 1.
3. Place the cover/cup top a embly on the drip tray and
in tall on the di pen er.
ELECTRIC L REQUIREMENTS
C UTION: The di pen er mu t be di connected from the power ource until pecified in Electrical Hook-Up .
The di pen er ha an attached cord et and require a 2-wire, grounded, individual branch circuit rated 120
volt ac, 15 amp, ingle pha e, 60Hz. The mating connector mu t be a NEMA5-15R. (Refer to the dataplate for
exact electrical requirement .)
ELECTRIC L HOOK-UP
C UTION: Improper electrical in tallation will damage electronic component .
1. An electrician mu t provide electrical ervice a pecified.
2. U ing a voltmeter, check the voltage and color coding of each conductor at the electrical ource.
3. Connect the di pen er to the power ource.
4. If plumbing i to be hooked up later, be ure the di pen er i di connected from the power ource. If
plumbing ha been hooked up, the di pen er i ready for Initial Fill .

3. En ure that the Main Water Valve and the Water Bath Valve Fig 4, are turned off (handle po itioned at 6 o’clock
and 12 o’clock, re pectively,) and that the Refrigeration Switch Fig 3, i in the OFF (rear) po ition.
4. Turn on the water upply.
5. While ob erving the water bath ight gauge (the clear tube located ju t to the left of the plumbing connection ,)
begin filling the water bath by rotating the handle of the Water Bath Valve counterclockwi e to the 9 o’clock
po ition.
6. When the water level in the ight gauge come within 1 inch (25.4 mm) of the clear pla tic tee, reduce the water
flow by rotating the handle of the Water Bath Valve clockwi e to the 11 o’clock po ition.
7. When the water in the water bath ight gauge begin to trickle down into the drip tray, turn the Water Bath Valve
off by rotating the handle clockwi e to the 12 o’clock po ition.

Bath Valve off by rotating the handle clockwi e to the 12 o’clock po ition.
11. Place the Refrigeration Switch ON (forward.)
12. It will take approximately 4 hour at 70 degree F (21 degree C) ambient to create the ice bank required for
full di pen er performance. During thi time, ome further trickling from the water bath i expected due to
expan ion cau ed by ice bank formation. While the refrigeration y tem i creating the ice bank, the di pen er
may be readied for u e a de cribed in
Loading, Priming and Adju tment.
13. The di pen er will afely tore concentrate once the “COOLING” indicator completely extingui he (not lit
teadily or fla hing.)
