Requirements section,

Requirements section, item 2, utilizing the manufacturer's published capacities for an entering water temperature of 90°F (cooling); however, the total cooling capacity shall not be more than two times the total cooling load. The gallon per minute flow rate shall be within the range specified by the manufacturer. − Earth Coil Design ⇒ The earth coil shall be sized and installed as recommended by the "Closed Loop/Ground-Source Heat Pump Installation Guide" and the "Ground Source Systems: Design and Installation Standard" by the International Ground Source Heat Pump Association. The earth coil design length shall satisfy the heat gain or heat loss, whichever is greater, for the structure. ⇒ The final earth coil design shall be determined by the QCN member, equipment distributor, and/or heat pump manufacturer. A computer printout (or equal) and sketch of the earth coil layout shall be available for review at the request of the inspector. − Earth Coil Installations ⇒ Earth coils may be installed in either parallel or series. When parallel coils are used with a reduced header design or a reverse return header design, the total effective length of the individual loops shall be within 5 percent of each other to ensure balanced fluid flow through the loops. ⇒ Pipes entering the building through a foundation wall or floor shall be sealed and/or protected. The pipes shall be contained in a sleeve to protect them from chafing on the floor or wall as they expand and contract. If the possibility of ground water seepage through the opening exists, the area around the piping shall be protected and sealed
