The Auxiliary Cooling Module is located outdoors and will be connected to the refrigerant line set outside the building. ® Figure 1. Auxiliary Cooling Module Placement in EarthLinked System Location Requirements for the Auxiliary Cooling Module: 1. Within 40 Feet of the earth loop line set. Minimize refrigerant line lengths. - Page 6 6. On a solid, level mounting slab. The mounting slab should extend a minimum of 2 inches beyond the sides of the Auxiliary Cooling Module. To reduce the possibility of noise transmission, the mounting slab should NOT be in contact with or be an integral part of the building foundation.
