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 & 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.
• Before installation, Check the insulation on the inner side of
the sleeve. If there is no insulation, place the insulation.

fill the gap with putty.
