GENERAL DESCRIPTION IMPORTANT: To the user of this manual This manual is a guide for installing, operating, and maintaining this equipment. Refer to Table of Contents for page location of information pertaining to questions that arise during installation, operation, service and maintenance, or troubleshooting this equipment. GENERAL DESCRIPTION This section gives the description, theory of operation, and design data for the four, five, and six flavor Universal Tower Post Mix Dispensing Stations hereafter referred to as units (see Figure 1). UNIT DESCRIPTION The units are equipped with either electric or manually operated dispensing valves and are lightweight and can be island mounted, installed on front or rear countertop, or installed on a drop in ice bin. This unit can be used with a remote electric cooling unit or can be used in cold plate cooling system. The units are set up at the factory to dispense a still (non carbonated) drink from second (facing front of unit) dispensing valve from the left and carbonated drinks from remaining valves. The still drink valve may also be converted to dispense a carbonated drink as instructed in this manual. All adjustments to unit are easily accessible. One dispensing valve cover, with water lever on its side, is loose shipped with unit and allows one dispensing valve (normally No. 1) to dispense carbonated water only when lever is actuated. Installation of unit, installation of LOOSE SHIPPED PARTS, connection of unit to plain and carbonated water supplies and syrup supplies, plugging transformer power cord (if applicable) into electrical outlet with proper electrical requirements, and adjustments is all that is required for unit operation. An optional Lighted Merchandiser Assembly Kit (P/N 167193 000) is available for units not provided with lighted merchandiser. CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be sanitized and all sanitizing solution must be purged from the syrup systems. All water must also be purged from the plain and carbonated water systems. A freezing ambient environment will cause residual water in the Unit to freeze resulting in damage to internal components.

ALL ELECTRICAL WIRING MUST CONFORM TO NATIONAL AND LOCAL ELECTRICAL CODES. 5. Close to a plain water source if still (non carbonated) drink will be dispensed. NOTE: Drip tray drain hose, routed to a waste container, is not recommended due to sanitation and cleaning problems. Connection of drain hose to a permanent drain is recommended. 6. Close to a permanent drain for connection of unit drip tray drain hose. INSTALLING UNIT INSTALLING UNIT ON COUNTERTOP (see Figure 5) 1. Place and tape MOUNTING TEMPLATE (item 17) in position on countertop. NOTE: Access hole, covered by plate on back of unit base, may be used to route lines, drip tray hose, and power cord(s) (if applicable) in and out of unit instead of through holes cut in countertop. 2. Drill and cut indicated holes on template in countertop, then remove template. 3. Remove two screws securing unit top cover, then remove cover. 4. Remove unit back access panel by lifting panel straight up and out. 5. Very carefully, tip unit over and lay on its back side. 6.

SYRUP FLAVOR CHANGE Sanitize syrup system as instructed, then install full tank of new flavor syrup. 9 300205000
CLEANING AND SANITIZING DAILY CLEANING OF UNIT Daily cleaning of unit should be performed at end of daily operation as instructed. WEEKLY CLEANING OF DISPENSING VALVES Dispensing valves should be cleaned at least once a week as instructed. SANITIZING SYRUP SYSTEMS Syrup systems should be sanitized every 90 days following Sanitizer Manufacturer s recommendations as instructed. 300205000 10
SERVICE AND MAINTENANCE This section describes service and maintenance procedures to be performed on the unit. IMPORTANT: Only qualified personnel should service internal components or electrical wiring. PREPARING UNIT FOR SHIPPING OR STORAGE NOTE: When indicator on CO 2 cylinder regulator assembly 1800 psi gage is in shaded ( Change CO 2 cylinder ) portion of dial, CO 2 cylinder is almost empty and should be replaced. 3. Check CO 2 supply daily and if necessary, replenish as instructed. ADJUSTMENTS CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be sanitized and all sanitizing solution must be purged from the syrup systems. All water must also be purged from the plain and carbonated water systems. A freezing ambient environment will cause residual water in the Unit to freeze resulting in damage to internal components. REMOVAL OF TOP COVER, BACK ACCESS PANEL,CUP REST, AND LIGHTED MERCHANDISER DOME (see Figure 5) TOP COVER Top cover (unit without lighted merchandiser) or lighted merchandiser/top cover assembly are removed in the same manner. Remove two screws, then lift top cover or lighted merchandiser/top cover assembly up off unit. BACK ACCESS PANEL 1. Remove top cover as instructed. 2. Remove back access panel by lifting panel up and out of unit. CUP REST Lift cup rest up out of drip tray to remove. LIGHTED MERCHANDISER DOME Pull right side (facing front of unit) of merchandiser housing out far enough to clear end of dome, then lift dome up and out of housing. PERIODIC INSPECTION 1.

SANITIZING SYRUP SYSTEMS IMPORTANT: Only qualified personnel should perform sanitizing procedure. The syrup systems should be sanitized every 90 days following Sanitizer Manufacturer s recommendations. Use Chlor Tergent (Oakite Products, Inc.) or equivalent sanitizer. IMPORTANT: If necessary to disassemble and clean dispensing valves syrup flow regulators, do not intermix their pistons and cylinders as they are precision matched sets. Refer to Remove and Replacement Procedures in this manual section for instructions. 1. Remove quick disconnects from soft drink tanks, then rinse quick disconnects in plain water. 2. Following Sanitizer Manufacturer s instructions, fill clean empty soft drink tank with sanitizing solution. 3. Connect sanitizing solution tank into syrup system to be sanitized. 4. Place waste container under applicable dispensing valve. Open dispensing valve to permit sanitizing solution to purge syrup out of syrup system and valve. Continue to draw from dispensing valve until sanitizing solution is dispensed, then close valve. 5. Repeat steps 3 and 4 preceding to purge syrup from and install sanitizing solution in remaining syrup systems. 6. Follow Sanitizer Manufacturer s application instructions. 7. Remove tank containing sanitizing solution from syrup system and install tank containing syrup. WARNING: Flush sanitizing solution from syrup system as instructed. Residual sanitizing solution left in system could create a health hazard. 8. Place waste container under applicable dispensing valve. Open dispensing valve to permit syrup to purge sanitizing solution from syrup system and valve. Continue to draw from dispensing valve until all sanitizing solution has been flushed from system, then close valve. 9.
