EQUIPMENT SELECTION PROCEDURE Correction Factors Cooling / Heating Correction Factors For Single Zone Extended Piping 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. Find the corresponding cooling or heating capacity correction factors as shown below.
PAGE 44
EQUIPMENT SELECTION PROCEDURE Correction Factors Single Zone Extended Piping Wall Mounted Engineering Manual Check the Indoor and Outdoor Unit Selection(s) Compare the corrected cooling and heating capacities to the load calculations. Is each capacity sufficient for the zone it serves? For the indoor unit, the corrected capacity must be at least equal to the total of the cooling design load (plus ventilation load, if applicable) for the space served by the indoor unit.

PLACEMENT CONSIDERATIONS Indoor Unit Selecting the Best Location for the Indoor Unit Figure 25: Extended Piping Indoor Unit Clearance Requirements. Single Zone Extended Piping Wall Mounted Engineering Manual Follow required best practices when choosing an indoor location for the single zone indoor unit. Do’s • Minimum clearance of indoor unit from the top of the unit to the ceiling must be greater than 8 inches.
PAGE 47
PLACEMENT CONSIDERATIONS 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.

PLACEMENT CONSIDERATIONS Outdoor Unit Planning for Snow and Ice, continued. CAUTION Single Zone Extended Piping Wall Mounted Engineering Manual 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.

PLACEMENT CONSIDERATIONS Outdoor Unit Single Zone Extended Piping Wall Mounted Engineering Manual Minimum Clearance Requirements for Single Zone Extended Piping Systems Proper clearance for the outdoor unit coil is critical for proper unit operation. When installing the outdoor unit, consider service, inlet and outlet and minimum allowable space requirements as illustrated in the diagrams below. Specific clearance requirements in the diagram below are for Single Zone Extended Piping Wall Mounted systems.

PLACEMENT CONSIDERATIONS Installing Outdoor Units Indoors Installing Outdoor Units Indoors Benefits of Installing Outdoor Units Indoors • • • • • Shelters the outdoor unit from direct exposure to prevailing winds that decrease the heating capability of the outdoor unit. Protects equipment from freezing precipitation and / or potential ice build-up that could hinder unit operation. Maintains coil heat transfer efficiency by reducing the number of and shortening the cycle time for defrost operation.

REFRIGERANT PIPING DESIGN Design Guideline Summary Device Connection Limitations Single Zone Wall Mounted Extended Piping Engineering Manual Single-zone systems consist of one outdoor unit and one indoor unit. One of the most critical elements of a single zone system is the refrigerant piping. The table below lists pipe length limits that must be followed in the design of a Single Zone Extended Piping Wall Mounted refrigerant pipe system. Refer to the figure for maximum length and elevation of piping.
