Chapter 4.I. Selecting and Installing Product-Dispensing Systems*

Introduction Several types of wall-mounted product-dispensing systems are available. Most product vendors have a preferred system that they provide for their products. They can assist with the selection of systems and the type of installation. The following information provides useful material to discuss with a vendor and what should be considered when planning to install a dispenser. x Features of product-dispenser models o There are numerous options, including flow options, supporting hardware, dilution ratios for specific concentrates, backflow options, installation options, the number of products and containers that can be filled by a system, and so forth. o A dispensing system could be gravity-fed, pneumatic, or electronically monitored (or similar). o Many vendors will supply a dispensing system at no cost when a specified amount of product is purchased from them. x Recommendations for selecting product-dispensing systems o Use only manufacturer-authorized products with the manufacturer’s specific dispensing system. o Consider the system’s security. Some have a lock and key mechanism or a tamper-resistant feature built into the system. If the dispensing system is not designed with this feature, a dispensing system enclosure is an alternative. o A dispensing system should have a backflow prevention feature to prevent cross- contamination of the potable water system. Some municipalities require this. x Installation criteria for product-dispensing systems o The installation and maintenance of the product-dispensing system should be conducted by the manufacturer in accordance with manufacturer’s instructions and requirements. o The product-dispensing system should be physically and visually accessible from the front for operation and for normal maintenance with tools, test equipment, and replacement parts. o The product-dispensing system should be installed in an area that has adequate storage facilities for the product concentrates, available potable water source connections, and adequate ventilation.
