proper air flow and cooling. 
• Do not install these units into a rack or other enclosure that 
doesn't leave room on either side for the unit fans. 
• Do not block the sides of the units (where fans are), or 
disconnect the fan.

or covers before operating the units. 
• Failure to do so can result in the units overheating very 
quickly, which can permanently damage them.
