•
The DR90 is designed to be installed indoors in a space that is protected from rain and flooding.
•
Install the unit with space to access the front panel for maintenance and service.
•
Avoid directing the discharge air at people, or over the water in pool areas.
•
If used near a pool or spa, be certain there is no chance the unit could fall into the water or be splashed,
and that it is plugged into a ground fault interrupt (GFI) outlet.
•
To ensure quiet operation, do not place the device directly on the structural supports of the home.
•
A drain pan must be placed under the unit if installed above a living area or above an area where water
leakage could cause damage.
