Leg Assembly

The legs must be unbolted from their collapsed shipping position and extended prior to placing
the unit on its pad. Each leg extends down approximately 18 inches (457 mm) and reattaches
using the same bolts.
NOTICE: Failure to extend the legs will result in poor air distribution
over the cooling coil resulting in significant capacity reduction and
system failure.
Concrete pads are often used to provide support for the heat exchanger when set on the
ground. Bolt holes in the bottom of each leg can be used to anchor the unit. Units mounted
on the roof should be placed on or suitable curbs or rails designed to distribute the unit weight.
Standard practices and in accordance with local codes should be followed in either instance.
