Wind shields are required to block prevailing winds across the outdoor coil. Shielding of the outdoor unit can be accomplished by building design or by appropriately placed shrubbery or by a site-constructed wind shield. Contractors should also consult the Canadian Electrical Code for minimum spacing requirements; 12" is adequate for airflow but the electrical code will require greater clearances depending on the type of material used.
