INTRODUCTION
USE OF THIS GUIDE
This guide is intended to assist regulatory authorities, designers, and installers in determining the
suitability of specific swimming pool, spa, hydromassage bathtub and fountain products in a
particular installation and use, and to address concerns related to fire, shock, plumbing, gas,
and/or mechanical hazards.
Products are Listed or Classified by UL under an appropriate product category. A four-letter code
(shown in parenthesis) following every category title in this guide is the UL product category code
designation. A list of product categories evaluated by UL, along with the applicable standard(s),
can be found in Appendix B.
Each UL product category code provides a direct link to the Guide Information for the product
category. The Guide Information includes the scope of the products covered, information relating
to limitations or special conditions applying to the product, the requirements used for the
investigation of the products, installation and use information, and information on product
markings and the UL Mark to be used on the product. Guide information is available in the UL
White Book and online at www.ul.com/database.
The product markings identified in this guide do not include every possible marking that could be
provided either on a product or in its installation or operation instructions. The purpose of these
markings is to provide you with an indication of the type of text and location of markings that
address features that may be critical in determining if a product is certified and / or if it is installed
correctly. Refer to the specific Guide Information for the product category for additional marking
information.
The numbering for code sections used in this document may change as the specific code is
updated. A list of model codes and standards applicable for each product can be found in
Appendix C.

INFORMATION ON LISTING VERSUS CLASSIFICATION
Most codes and regulations require the certification of this equipment to applicable safety-related
standards. They also may require this equipment to be certified to energy performance standards
as well. Products that are certified to safety-related standards have been evaluated with regard to
all reasonably foreseeable safety-related hazards, including fire, electrical shock and mechanical
hazards. Such products are termed ―UL Certified‖ or ―UL Listed.‖ Products that are certified to a
limited range of hazards, or for use under specific conditions are termed ―UL Classified‖.
It is important to distinguish the difference between ―UL Certified‖ or ―UL Listed‖ and ―UL
Classified‖ and the relation these terms have with the term ―listed,‖ as used in various codes. The
term ―listed‖ in the codes generally indicates that the product is required to be evaluated in
accordance with the appropriate standard(s) by an independent third party certification
organization such as UL. The term ―listed‖ in the codes should not be confused with the term ―UL
Listed,‖ as explained above. It is important to recognize that not all certification agencies make
this distinction in their certification services.
