General
UP Model NL units are factory assembled air conditioners
designed to be installed along side the home or building. Field-
installed electric heater accessories are available to provide
supplemental electric heat combined with electric cooling.
The units are completely assembled on rigid base rails. All
piping, refrigerant charge, and electrical wiring is factory
installed and tested. The units require only electric power and
duct connections at the point of installation.
The electric heaters have nickel-chrome resistance wire
elements and utilize single point power connection.
