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 ) 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.
