If the air conditioner is mounted to the cabinet door you must be sure that the door hinges 
will support the additional weight of the air conditioner. Also be certain that when the door 
is opened fully, the cabinet does not become unbalanced. The actual weight of the unit can 

be found in the Technical Data on page 12.

2.

Attach two hooks to your enclosure with supplied hardware. 

3.

Route the power cord through the bottom cutout in your enclosure. It is recommend that a lift truck be 
used to mount the air conditioner. Hang the air conditioner on the hooks. Before the lift truck lowers the 
air conditioner make sure that the hooks are located inside of the small cutouts on the front panel.   

4.

Tighten the air conditioner bottom flange to your enclosure with supplied hardware (see mounting 
drawing). 

5.

If the mounting panel of your enclosure is not stiff enough (moment inertia is less than 0.005"

4

) it is 

recommended that the three additional supplied screws be used at approximately the middle of the unit 
height for proper gasket compression. The screws must be started from inside your enclosure. 

6.

Attach the supplied drain hose to the drain tubing on the bottom of the air conditioner using the plastic 
clamp.
