EQUIPMENT SELECTION PROCEDURE Single Zone Mega, Standard Efficiency, and Mega 115V Wall Mounted Engineering Manual Correction Factors Cooling / Heating Correction Factors For Single Zone Mega, Standard Efficiency, and Mega 115V Wall Mounted systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit.
PAGE 73
EQUIPMENT SELECTION PROCEDURE Correction Factors Defrost Correction Factor for Heating Operation The outdoor unit heating capacity may need to be adjusted for frost accumulation on air-cooled systems. If design day conditions are below the dewpoint of the surrounding air, frost may not be a problem and no correction factor is needed. In certain weather conditions, however, frost may form and accumulate on the air-cooled outdoor unit coil and impact the coils ability to transfer heat.

PLACEMENT CONSIDERATIONS Single Zone Mega, Standard Efficiency, and Mega 115V Wall Mounted Engineering Manual Outdoor Unit Selecting the Best Location for the Outdoor Unit • DANGER Do not install the unit in an area where combustible gas will generate, flow, stagnate, or leak. These conditions can cause a fire, resulting in bodily injury or death. • Do not install the unit in a location where acidic solution and spray (sulfur) are often used as it can cause bodily injury or death.
PAGE 77
PLACEMENT CONSIDERATIONS Outdoor Unit Planning for Snow and Ice, continued. When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on sidewalks or driveways, which will create unsafe conditions. Properly install and insulate any drain hoses to prevent the hose from freezing, cracking, leaking, and causing unsafe conditions from frozen condensate.

Windbreak Ocean winds will cause corrosion, particularly on the condenser and evaporator fins, which, in turn could cause product malfunction or inefficient performance. • • • • • • Avoid installing the outdoor unit where it would be directly exposed to ocean winds.
PAGE 79
PLACEMENT CONSIDERATIONS Outdoor Unit Minimum Allowable Clearance and Service Access Requirements Proper clearance for the outdoor unit coil is critical for proper operation. When installing the outdoor unit, consider service, inlet and outlet, and minimum allowable space requirements as illustrated in the diagrams below. • Include enough space for airflow and for service access.
