PREPARING JOBSITE FOR UNIT INSTALLATION —
To save time and to reduce the possibility of costly errors, set
up a complete sample installation in a typical location at
jobsite. Check all critical dimensions such as pipe and wire
connection requirements. Refer to job drawings and product
dimension drawings as required. Instruct all trades in their
parts of the installation. Units must be installed in compliance
with all applicable local code requirements.
IDENTIFYING AND PREPARING UNITS — Be sure
power requirements match the available power source. Refer to
unit nameplate and wiring diagram. In addition:
• Check all tags on unit to determine if shipping screws are
to be removed. Remove screws as directed.
• Rotate the fan blade by hand to ensure that the fan is
unrestricted and can rotate freely. Check for shipping
damage and fan obstructions.
Step 2 — Position the Unit —
recommended for outdoor use. For single unit installation, see
Fig. 3. For multiple or parallel unit installation, see Fig. 4. Unit
should be mounted on concrete and fastened to anchor bolts to
prevent the unit from tipping. Units installed in areas that are
exposed to ambient temperatures below freezing (32
should be installed on a snow/ice stand as defined by local
codes.

each connected diagonally to bottom rigging hole locations.
Make sure each cable is at least 26 feet long, to avoid excess

to the unit from lifting cables; 2-in. thick wood, cloth, or
cardboard spacers should be installed between cables and
contact surfaces of the unit.
Do not stand below the unit while it is suspended in the air.
If the unit falls, it will lead to severe personal injury or
death.
