Page 8: Connecting To Syrup Supply
Connecting to Syrup Supply Installations requiring tubing runs over 50 feet may encounter pressure fluctuation issues due to excessive pressure drop and subsequently cause false sold out conditions. Use at least 1/2” ID tubing in these situations. Also consider installing booster pumps on the supply lines. Increasing the regulated CO2 pressure on the syrup pumps can also help maintain proper syrup pressure at the dispenser. -

STARTING UP THE DISPENSER Leak Check and Prime Remove the side panels by loosening the two screws located at the bottom of the panel and then lifting off the frame. Remove the drip tray by lifting and pulling forward and then remove the splash plate and front cover to expose the solution modules. -
Page 21: Initial Power Up
Initial Power Up Plug the dispenser into the power supply and verify by looking at the LCD located behind the merchandiser. The display should be on the home screen showing the status of the barrels. If the firmware has just been updated, then the dispenser will prompt the operator to answer the following questions: 1) desired language, 2) number of barrels, and 3) dispenser serial number. - Page 22 setting. Check the specifications for the flavor if unsure of the target brix. Note: Light or diet product has a low brix and can cause problems with the dispenser if not properly set up. Although these products have ingredients to replace the anti-freezing properties of sugar, they can still create excessive ice if not carefully brixed according to their specifications.

Page 25: Drink Too Heavy
Drink Too Heavy A drink with not enough CO2 will be heavy and may look dark in the barrel. To increase the CO2 content in the drink, increase the setting in the CARBONATION ADJUSTMENT menu. Approximately ten 16 oz drinks will need to be dispensed before the product in the barrel has re-conditioned to the new settings. -
Page 26: Cleaning And Sanitizing
CLEANING AND SANITIZING General Information The 77X dispensers are shipped from the factory cleaned and sanitized in accordance with NSF guide- lines. After installation of the dispenser, the operator must provide continuous maintenance as described in this manual and/or state and local department guidelines to ensure proper operational and sanitization requirements are met. -
Page 27: Sanitizing
Sanitizing The dispenser should be sanitized yearly. Prepare a chlorine solution containing 100 PPM of available chlo- rine with clean water at 90 to 100°F (32 to 44°C). Commercial beverage equipment sanitizing and cleaning solutions such as Kay-5 or Stera Sheen are preferred because they also contain surfactants to assist in cleaning. -
Page 28: Routine Maintenance
ROUTINE MAINTENANCE Air Filter Cleaning The air filter must be cleaned monthly to ensure proper operation of the dispenser. A dirty air filter will reduce the refrigeration capacity and can potentially damage the compressor. To remove the filter, open the front merchandiser and locate the pull handle protruding from the front panel. -

Error #140: Low regulated CO2 PSI The regulated CO2 pressure dropped below 50 PSI. Ensure the CO2 supply is not low. Check the “carbonation” regulator on the header tray and ensure it is set to 60 PSI. Error #150: High regulated CO2 PSI The regulated CO2 pressure is above below 70 PSI. - Page 34 Error #510: Compressor not turning on Manually turn on compressor and ensure the contactor located in the electrical box engages. If contactor does not engage then check for 24 VAC at the contactor coil. Note: The voltage will read ~19 VAC when not powered. Refer to the wiring schematic for details. If no voltage, install a new control board and check for 24 VAC again.
- Page 35 Error #550: Excessive refrigeration pressure The high side refrigeration pressures (as read on LCD display) during a freeze cycle should not exceed 450 PSI. Ensure dispenser has 3” clearance on sides and back and no obstructions overhead. Failure to provide adequate clearances will result in poor airflow or the recirculation of hot discharge air from the condenser.
- Page 36 Error #611, 612, 613, 614: CO2 or Solution Leak The barrel pressure is rising during a fill circuit diagnostic test. Determine if the barrel is filling with CO2 or liquid. If the barrel liquid level is low enough use a flashlight to look at the back of the barrel and see if liquid is entering the barrel.
