•
The DR90/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.
!
1. Never operate a unit with a damaged power cord. If the power cord is damaged it must be
replaced by the manufacturer, its service agent, or similarly qualified person in order to
avoid a hazard.
2. The appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they
