Getting Started
Unpacking: Carefully unpack and inspect the entire unit prior to installing. Ensure
there is no visible damage and all contents are included.
Contents: Evaporative Cooler Unit(1), Manual(1)
Choosing Best Location: Ensure the unit location meets the following
• Unit is a reasonable distance from sources of heat, smoke or fumes—and in
accordance with any codes or regulations. It is important that the air being drawn
into your living space is clean and fresh.
• Unit is positioned for optimal access for servicing requirements.
• Roof structure will adequately support the weight of the cooler.
Note: This cooler is designed to be mounted in either a side discharge position or down
discharge position. It is shipped from the factory in the down discharge position. If side
discharge is desired, it will be necessary to remove the motor/prop/brackets from the
down position and re-install in the non-media side.
See Fig. 1 on page 2 of this manual.
This step should be performed with the cooler still on the ground level.
