Outdoor units must be moved and stored vertically to prevent oil from leaking from the compressor.
Selection requires knowing the cooling capacity needed, design cold water input and output temperatures, design water flow, design input temperature of air to condensing unit, altitude above sea level, and design fouling factor.
The refrigeration circuit must be extracted and delivered to the gas manufacturer for recycling because it contains greenhouse-effect fluorinated gas.
