DESCRIPTION
Units are a single piece , gas heating/ele ctric cooling unit , with a low profile , pre-wired, tested and charged at the factory.
The units have the capabi lity for convertible supply and return openings and are inte nded for installation on a n accessory
curb (ordered separatel y), or for slab mounting (for horizontal duct connections). Unit s a re designed to accept a fieldinstalled economizer, enthalpy contro l, m anual or 2-posi tion o utside air da mper, roof curb , as wel l as 3 ch oice s of ga s heat.
Refer to accessory chart below fo r full li sting.
