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). Ensure
that when the door is fully open that the enclosure will not topple over due to the off-center load.
