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
—
Units are
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
F)
should be installed on a snow/ice stand as defined by local
codes.
HANDLING THE UNIT — The angle of inclination should
not be more than 15
when carrying the unit to avoid overturn
of the unit
.
Forklift handling: — When using a forklift for lifting or
transporting the unit, insert the prongs of the forklift into the
rectangular holes as shown in Fig. 5.
Lifting the unit: Make sure the lifting cable is able to
withstand the weight of the unit.
Connect the cables to the
bottom rigging hole locations shown in Fig. 6. Use 2 cables,
each connected diagonally to bottom rigging hole locations.
Make sure each cable is at least 26 feet long, to avoid excess
tension and force on the surfaces of the unit.
To avoid damage
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.

DANGER
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.
