•  Ensure that the intake vents do not recycle hot air from the exhaust ven\
t.
•  When operating the projector in an enclosed space, ensure that the surro\
unding air 
temperature within the enclosure does not exceed operation temperature w\
hile the 
projector is running, and the air intake and exhaust vents are unobstruc\
ted.
•  All added enclosures should pass a certified thermal evaluation to ensure that the 
projector does not recycle exhaust air, as this may cause the device to shutdown even 
if the enclosure temperature is with the acceptable operation temperatur\
e range
.
Caution:
Ceiling  installation  must  be  done  by  a  qualified  professional.  Contact  your  dealer  for  more  information.  It  is 
not recommended you install the projector by yourself.
