3.1 HOW TO INSTALL THE UNIT

Dimension of air conditioner

CAUTION

There are sharp edges that can cause serious cuts.

When lifting the air conditioner, it is HEAVY. Use 2 people to lift.

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.

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.
