c. single-split, multi-split, and multi-circuit systems with matching assemblies or single package for use in ducted and/or non-ducted distribution systems;
d. intended for space-heating and/or air-conditioning applications in buildings;
e. electrically driven, mechanical, vapour-compression-type systems; and
f. rated below 65,000 Btu/h (19.0 kW ) heating or cooling at standard rating conditions, [in accordance with Clause 5.2].

Note: This includes space constrained single-package or split-system and small-duct high-velocity central air conditioners and heat pumps matching assemblies of the type classified in Clause 1.2 and intended for air conditioning and space-heating  applications in buildings.

1.2 Unitary equipment
Unitary equipment within the scope of this Standard is outlined in Table 1.

1.3 Terminology
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.

1.4 Units of measurement

The values given in IP (inch-pound) units are the standard. Metric values given in parentheses are for information only.
