Supplement #1 to CSA F379 Series-09, Packaged solar domestic hot water systems (liquid-to-liquid heat transfer)

1.1
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 packaged 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 procedures. 

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 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 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 requirements. 

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.

F379.2-09 - Packaged solar domestic hot water systems for seasonal use

Scope

1.1
This Standard applies to the performance, durability, and safety of packaged seasonal-use solar domestic hot water (SSDHW) systems that are not intended to be operated in freezing conditions. In these systems, freeze protection is accomplished manually (e.g., complete drainage) with or without a device intended to offer limited freeze protection. 

Note: This Standard was developed to specifically address systems not intended for use in freezing conditions. For the most part, the other requirements of this Standard are similar to those of CSA F379.1. It may be assumed that any system that meets the requirements of CSA F379.1 is recognized as meeting or exceeding the requirements of this Standard. 

1.2
This Standard covers systems that provide all, or a significant fraction of, the seasonal hot water requirements of small buildings, including vacation homes, by solar energy. 

1.3
This Standard applies primarily to systems that heat process water directly or use water as the heat-transfer fluid, but it does not exclude other systems. 

1.4
This Standard specifies requirements for packaged systems as proposed by a manufacturer and for all subcomponents and materials. 

1.5
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 procedures. 

Note: The installation of systems that meet the requirements of this Standard is covered by CSA F383. 

1.6
This Standard is not intended as a design specification or an instruction manual for untrained persons. 

1.7
In CSA Standards, "shall" is used to express a requirement, i.e., a provision that 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 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 requirements. 

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
