SECTION I: GENERAL INFORMATION
PHE units are factory assembled heat pumps designed for outdoor
installation on a rooftop 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
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
