All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what will happen if the instructions are not followed.
NOTICE
You can be killed or seriously injured if you do not follow instructions.
You can receive minor or moderate injury if you do not follow instructions.
A message to alert you of potential property damage will have the word “NOTICE”. Potential property damage can occur if instructions are not followed.

Vert-I-Pak Installation Recommendations
For proper unit performance and maximum operating life please refer to the minimum installation clearances
below.
Figure 1
VERT-I-PAK® units must be installed on an outside wall. Confined spaces and/or covered areas should be avoided. Units should be installed no closer than 12" apart when two units are side by side. If three or more units are to operate next to one another allow a minimum of 60" between units or pairs of units. Also, a vertical clearance of 60" should be maintained between units. Units installed on the bottom floor should be mounted at least 6" off of the ground.
