11、1 This Standard applies to the performance, durability, and safety of packaged solar domestic hot water (SDHW) systems that use liquid-to-liquid heat transfer and liquid heat storage media suitable for year-round use.1.2 This Standard specifies requirements for both factory-packaged and add-on packa

12、ged systems.1.3 This Standard applies to the components and materials supplied by the manufacturer, the assembly and installation instructions, and the operation of the system after it has been assembled according to these instructions. It does not apply to site preparation or installation procedure

13、s.Note: The installation of systems that meet the requirements of this Standard is covered by CSA F383.1.4 This Standard is not intended as a design specification or as an instruction manual for untrained persons.1.5 In CSA Standards, “shall” is used to express a requirement, i.e., a provision that

14、the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or

15、capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as r

16、equirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.1.6 The values given in SI (metric) units are the standard. Any values given in parentheses are for information purposes only.2 Reference publicationsThis Standard refers to the follo

17、wing publications, and where such reference is made, it shall be to the edition listed below, including all amendments published thereto.Note: In cases where the editions listed below are amended, replaced by new editions, or superseded by another standard during the life of this referencing Standar

18、d, it is the responsibility of the users of this Standard to investigate the possibility of applying those amendments, new editions, or superseding standards.3(Replaces p. 3, January 2009)F379S1-11 Canadian Standards AssociationMarch 2011CSA (Canadian Standards Association)ANSI Z21.10.1-2009/CSA 4.1
