DESCRIPTION

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.
