GENERAL
MagnaDRY™ units are single package air conditioners with
optional gas heating designed for outdoor installation on a
rooftop or slab and for non-residential use. These units can
be equipped with factory or field installed electric heaters for
heating applications.
These units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electri-
cal wiring is factory installed and tested. The units require
electric power, gas supply (where applicable), and duct con-
nections. The electric heaters have nickel-chrome elements
and utilize single-point power connection.
