2.

a. Mechanical refrigeration systems containing a Group A1 or B1 refrigerant which are used only for air conditioning for human occupancy and which have their mechanical components located outdoors with the discharge from any relief valve located at least 20 feet from any building opening are exempt from periodic inspections.

b. An air intake opening that is part of an outdoor self-contained system under subd. 2. a. is not considered a building opening for the purposes of this subdivision.

(b) Any mechanical refrigeration system using a Group A2, B2, A3 or B3 refrigerant and having a capacity rated at or greater than 10 horsepower, 10 tons or 10,000 volt-amperes shall be inspected by the authorized agent or the department at least once every 12 months.
