CAUTION 
If mounting the air conditioner to the enclosure door, confirm with the enclosure manufacturer that the 
door’s hinges will support the air conditioner’s added weight (see equipment specifications). Insure 
that when the door is fully open that the enclosure will not topple over due to the off-center load.
