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.
