DESCRIPTION
Units are a single piece, gas heating/electric cooling unit, with a low profile, pre-wired, tested and charged at the factory.
The units have the capability for convertible supply and return openings and are intended for installation on an accessory
curb (ordered separately), or for slab mounting (for horizontal duct connections). Units are designed to accept a field-
installed economizer, enthalpy control, manual or 2-position outside air damper, roof curb, as well as 3 choices of gas heat.
Refer to accessory chart below for full listing.
FEATURES
• Standard one-year full product warranty.
• Five-year protection plan for the motor-compressor.
