General Information
About Blend-In-Cup
The Blend-In-Cup beverage system is a self-contained
dispensing unit that allows the operator to make flavor
combinations of blended and non-blended drinks. It
holds product flavoring in a refrigerated reach-in base
enclosure, has a refrigerated ice making machine and
includes one or two mixing modules.
The operator controls and accesses the unit using a
lighted touch screen. Icons on the drink selection
screens represent the primary flavor combinations for
the drinks. There are multiple drink size options. Menu
changes and additions are uploaded using a USB
mass storage device and the Menu Connect Software
platform.
On-screen instructions also include operator
procedures for cleaning/sanitizing, checking inventory,
replacing product bags, selecting drink sizes and
manually preparing drinks. Managers and technicians
have access to menu/software updates, diagnostics
and other service screens.
Serial Number Location
The Blend-In-Cup beverage system serial number is
listed on the serial number decal affixed to the middle
of the lower back panel. Another serial number decal
is located on the right side of the machine.

PRODUCT DELIVERY LOCATION
The location selected for the Blend-In-Cup Beverage
System must meet the following criteria.
• The air temperature must be at least 40°F (4°C),
but must not exceed 90°F (32°C), climate class 4.
• The location must not be near heat-generating
equipment or in direct sunlight and must be
protected from weather.
• Plain or Chilled Inlet Water Temperature
min/max = 40°F / 90°F (4°C / 32°C).
• Always use the water supply line supplied when
installing this appliance. Never reuse an old supply
line.
• Verify floor of install location is within 1/2” of level
front to back, side to side.
• Keep equipment area clear of combustible
material.
!
Warning
Carbon Dioxide (CO
2
) displaces oxygen.
Exposure to a high concentration of CO
2
gas
causes tremors, which are followed rapidly by
loss of consciousness and suffocation. If a CO
2
gas leak is suspected, particularly in a small
area, immediately ventilate the area before
repairing the leak. CO
2
lines and pumps must not
be installed in an enclosed space. An enclosed
space can be a cooler or small room or closet.
This may include convenience stores with glass
door self serve coolers. If you suspect CO
2
may
build up in an area, venting of the B-I-B pumps
and / or CO
2
monitors must be utilized.
