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 & Front grille, make certain there
is nothing within 20” back & front of sleeve & front grille,
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.
To maintain the best performance of LG PTAC
1. An insulation strip must be attached to prevent the re-circulation of exhaust air to inward
side from the either side of condenser space. The insulation strip is provided with the box.
2. After assembly of sleeve & Front grille, the gap should be 20” from both sleeve & grille.
For assembly PTAC Model refer the diagram given below.
