3.1 HOW TO INSTALL THE UNIT
For existing sleeve, you should measure the wall sleeve
dimensions.
Install the new air conditioner according to these installation
instructions to achieve the best performence. All wall sleeves
used to mount the new air conditioner must be in good
structural condition and have a rear grille that securely
attaches to the sleeve or the flange of the sleeve to secure the
new air conditioner.
• To avoid vibration and noise, make sure the unit is installed
securely and firmly.
When installing the sleeve, make certain there is nothing
within 20" of the back that would interfere with heat radiation
and exhaust air flow.
1) Take out the insulation strip from the upper packing.
2) Attach the insulation strip onto the rear upper side of the
wall sleeve.
3) To improve unit energy efficiency, it is recommended the
change of outside grille for an unit protection and an
addition of a plastic rear grille. (This is optional.)
4) Insulation strip prevents the exhaust air from re-entering
from either side of condenser space which may decrease
the cooling efficiency of condenser.
