Control panel clearance is 36 or 40 inch (914 or 1016 mm) depending on voltages, starter type, unit application
and local code; 42 inch (1067 mm) clearance required to other grounded parts; two units with panels facing
each other or other live parts require a clearance of 48 inch (1220 mm).
**
Sound attenuator may increase the footprint - submittal should be used.
