SIZE 07
All units are pre-wired, tested, and pre-charged with Puron® (R-410A) HFC refrigerant
at the factory. 48PG units are one-piece ultra-high efficiency rooftop cooling units with gas
heat. 50PG units are one-piece ultra-high efficiency cooling units with optional electric
heat. Units are factory tested in both heating and cooling modes. The unit is rated in accordance with ARI Standard 210 and 360, tested in accordance with UL Standard 1995 and
listed by UL and UL, Canada.
The 48PGD model is low heat, the 48PGE is medium heat, and the 48PGF model is high
heat. The 48PGL model is low heat with stainless steel heat exchangers, the 48PGM is
medium heat with stainless steel heat exchangers, and the 48PGN model is high heat with
stainless steel heat exchangers. The 48/50PG unit is field convertible from factory-furnished
vertical airflow to horizontal airflow.
