Air Delivery Clearances
Standard clearances for cassette air handlers require
5 feet of clearance in each direction. There should be
8 feet of clearance from the face of the cassette grille
to the floor. Inadequate clearances can cause system
freezing and temperature control problems.
Service and Maintenance Clearances
Make sure there are adequate clearances for future
maintenance and service. Allow enough room to access
the condensate pump assembly and the electrical
control box.
