Units should be installed by licensed contractor according to local code requirements.

After the leak test, apply insulat-

ing material tightly so that there is 
no gap.

When  the  piping  is  to  be  at-

tached to a wall containing metals 
(tin  plated)  or  metal  netting,  use 
a  chemically  treated  wooden 
piece  20  mm  or  thicker  between 
the wall and the piping or wrap 7 
to  8  turns  of  insulation  vinyl  tape 
around the piping.
To  use  existing  piping,  perform 
COOL  operation  for  30  minutes 
and  pump  down  before  removing 
the  old  air  conditioner.  Remake 

flare  according  to  the  dimension 

for new refrigerant.
