Joint Gap
• There are sharp edges that can cause serious cuts.
• If the unit is to be installed close to the seaside, it needs
additional treatment on the heat exchanger.
• When lifting the air conditioner, it is HEAVY.
Use 2 people to lift.
For existing sleeve,
you should measure the wall sleeve
dimensions.
You can 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 the 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.
• Before installation, Check the insulation on the inner side
of the sleeve. If there is no insulation, place the insulation.
• Check the bottom corner's joint gap of the sleeve, If there
is, fill the gap with putty.
To maintain the best
performance of the LG PTAC,
an insulation strip must be
attached. The insulation strip
is provided with the box.
Refer to the diagram below.
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) If anyone would like 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.)
