•
The DR90A3000/DR120A3000 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.
•
DR90/DR120 should be installed on a stationary base or sitting on the floor. It should not be
mounted above other HVAC components such as the A-coil.
!
