Sold Out light illuminates
when concentrate no lon-
ger passes through the
pump.
The concentrate is improperly thawed.
The temperature is not maintained
between 34×F - 40×F(1.1-4.5×C)
Assure proper thawing procedures have been fol-
lowed per the Minute Maid company instructions.
Check that McDonald’s walk-in cooler tempera-
ture is on the proper set point.
Check the dispenser cabinet temperature is at
34×F - 40×F(1.1-4.5×C).
High Brix readings result in a poor, pul-
sating/splashing dispense, erratic pump
amp draw, and consequently erratic
sold-out indications.
Check drink brix in procedure described on equip-
ment P.M. card using the hydrometer provided.
Check the drink flow rate under normal operating
conditions. The dispenser should pour a drink at a
flow rate of approximately 1.5 oz. Per second or
greater. If the flow rate is less, a check described
in the Sold Out section should be completed.
Improper loading procedures will usu-
ally result in low brix conditions and
thus erratic sold out indications.
Check that the pouch of juice is properly loaded in
the pouch holder. Tube fitting should be located at
the bottom of the pouch holder and the tube
should be approximately centered in the bottom
portion of the opening of the holder.
Check that the tube is correctly loaded in the
pump and the pump is fully locked (top and bot-
tom slide pins should be fully engaged into the
pump body).
Tube has been stretched through pump
when it was loaded. Pouch may not be
seated correctly.
Adjust pouch. If pouch is loaded correctly there
should be ample tube to reach the mixing cham-
bers without stretching the tube.
Check that the rollers on the pump are
spinning freely with no tube in place.
If the rollers are sticky or locked up see the plat-
form removal and cleaning procedure.
Sold Out light fails to reset
itself after door is opened
and closed (Sold Out light
stays illuminated)
Check the operation of the reset switch
located at the bottom left hand side of
the door.
Adjust Switch.
