2. SPECIFICATIONS AND REQUIREMENTS
2.1 General Requirements
The merchandiser is compatible with only the dispenser that corresponds to its merchandiser series, and will not function
properly if installed onto a dispenser outside of that series. The 771 and 772 multi-flavor dispensers belong to the 77x
series and therefore use the same merchandiser model; whereas, a 372 multi-flavor merchandiser should only be installed
on a 372 dispenser.
2.2 Dimension and Weight Specifications
2.3 Content Specifications
* Flavor images automatically scale without distortion.
† Use exact sizes for the background images. Graphics will be stretched and distorted if the size is incorrect.
‡The video area can display either a video or static image. Use exact sizes. Content will be stretched and distorted if the
size is incorrect.

3. INSTALLATION
The following installation instructions apply to merchandisers that are not already installed on dispensers upon arrival.
Since the merchandiser receives power from the dispenser and communicates with the main control board, it is important
that power and serial harnesses be connected correctly during installation.
3.1 Installation of 372 Multi-Flavor Merchandiser
1 Remove the merchandiser from the packaging and inspect it for damage or missing parts.
2Align the merchandiser hinges with the bolt holes located at the top-front of the dispenser, and secure all hex
bolts through the hinge and into the frame.
3Connect the door power and serial communication harnesses to their respective mate on the dispenser
(black connector with black connector, white connector with white connector).
4Push the merchandiser down until it snaps into place. Ensure that the pneumatic faceplate’s activation hose
stays looped and is not pinched when the merchandiser is closed.

4.2 Screen Layout
The multi-flavor setup allows the user to add one or more flavors to dispense with the base flavor in the barrel. The user
can select any variety of flavors; each flavor will be marked as it is selected. When one or more is selected, the POUR
button will appear to indicate that a drink is ready to be dispensed. The dispenser will continue to pour for as long as the
POUR button is held. If the POUR button is pushed without any flavors selected, only the base flavor will dispense. In
addition to displaying the flavor images, the screen will also show status messages.
The flavor messages are displayed as image overlays. When the status message appears, the flavor image will be obscured
so that the message can be seen. There are two flavor messages: "Selected" which is displayed when that flavor has been
selected for dispensing and "Sold Out" which is displayed when a flavor syrup is out.
The status messages will appear at the bottom-center section of the display. These messages will provide status information
for the barrel. For a list of all status messages, please refer to Section 7 of this manual.
After flavor selections are made, the status message area of the display will change to a "PUSH TO POUR" button.
Item Description
1 Flavor Buttons: Select flavor add-ins. Flavor messages will appear over flavors as image overlays.
2 Base Flavor Button: Flavor of the base syrup.
3 Barrel Status: Shows status of barrel.
4 Pour Button: Press and hold to dispense a drink.
5 Video Portion: Displays video (see Section 4.1)
4.3 Initial Set-Up
The flavor images will need to be set as part of the initial set-up of the merchandiser. Please refer to Section 5.1 for
additional information on menu options and Section 5.2 for additional information on updating the images for the flavors
(flavor add-ins and base syrup). Additionally, all flavor injection modules will need to be calibrated before the dispenser is
ready for store operation. Please refer to Section 5.8 for additional information on calibrating flavor modules.
All other door and dispense settings will be pre-configured.

5.7 Alternative Flavor Lockout
The "Alternative Flavor Lockout" can prevent any flavor set up as an "alternative" flavor from being dispensed. This icon
will only be shown in the menu when at least one alternative flavor has been set up under the "Configure Flavors" menu
option (please refer to Section 5.8 for additional information on setting up flavor types).
This option is available only to the store manager and service technician. The icon will appear for store operators if there
are any alternative flavors set up and, when selected, the screen will prompt for a password to be entered. Only the store
manager or service technician passwords can enable or disable the lock.
When the lockout is engaged (closed lock), any flavor set up as an alternative flavor will appear as locked on the main
