SECTION I: GENERAL INFORMATION

PHE units are factory assembled heat pumps designed for outdoor
installation on a roof top or a slab. Field-installed optional electric heater
accessories are available to provide supplemental electric heat com-
bined with electric cooling and heating.

The units are completely assembled on rigid, removable base rails. All
piping, refrigerant charge, and electrical wiring is factory installed and
tested. The units require only electric power condensate drain and duct
connections at the point of installation.

SECTION II: SAFETY
