This document provides installation instructions for the PHM3 Series Package Heat Pumps. It covers various aspects from safety labeling and dimensions to electrical wiring, start-up procedures, and operational sequences.
The PHM3 Series Package Heat Pumps are designed for outdoor installation, providing both cooling and heating functions. These units are self-contained, meaning all major components for both heating and cooling are housed within a single cabinet. They are intended to be placed on a ground-level platform, such as a concrete slab or concrete blocks, ensuring proper drainage and clearance from surrounding structures. The units utilize a circulating blower and a condenser fan for air distribution and heat exchange. Electric heat accessories are available to supplement the heating function when required.
