DESCRIPTION
All units are pre-wired, tested, and pre-charged with Puron® (R-410A) HFC refrigerant
at the factory. The 48PG units are one-piece ultra-high efficiency rooftop cooling units with
gas heat. The 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 360, tested in accordance with UL Standard 1995 and listed
by UL and UL, Canada.
The 48PGD model is low heat, the 48PGE model is medium heat, and the 48PGF model
is high heat. The 48PGL model is low heat with stainless steel heat exchangers, the 48PGM
model 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 available in vertical airflow or
horizontal airflow models.
