Installation of unit 6RWU0-02A
PTAC
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. The wall sleeve
used to mount the new air conditioner must be in good struc-
tural 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 with-
in 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 the unitʼs energy efficiency, it is recommended
to change the outer grille with a plastic grille.(This is option-
al for old models but New models readily comes with the
plastic rear grille)
4) Insulation strip prevents the exhaust air from re-entering
from either side of condenser space which may decrease
the cooling efficiency of condenser.

Insulation strip must be attached to prevent the re-circulation of exhaust
air to inward side from either side of condenser space. The insulation
strip is provided with the box.
