after the job is finished. During operation of the unit the front plate of
the  unit  should  be  attached.  Settings  are  still  possible  to  be  made
through the inspection opening.

NOTICE

Make  sure  that  all  outside  panels,  except  for  the  service
cover  on  the  electrical  component  box,  are  closed  while
working.

Close the lid of the electrical component box firmly before
turning on the power.
