EarthLinked compressor unit models. ® Application of the Auxiliary Cooling Module (ACM) to EarthLinked systems will require the use of two (2) field supplied Type ACR copper couplings to match the ACM with the line set vapor tube size. See the table below to determine the required coupling sizes. - Page 4 The dimensions data for the Auxiliary Cooling Module is shown in Figure 1.

Page 5: Installation
The Auxiliary Cooling Module is located outdoors and will be connected to the refrigerant line set (vapor tube) outside the building. ® Figure 2. 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 5. Away from windows, patios, decks, etc., where unit operation sounds may disturb the occupants. 6. On a solid, level mounting pad. The mounting pad should extend a minimum of 2 inches beyond the cabinet size of the Auxiliary Cooling Module. The minimum pad size is to be 22 inches by 46 inches.

A top view of typical Auxiliary Cooling Module and line set vapor line connections are illustrated in Figure 4. For new installations of an EarthLinked system with an ACM, an alternate method to the one shown in Figure 4 is to run a single piece vapor line from the compressor unit to the ACM and another single piece vapor line from the ACM to the vapor manifold of the earth loop system. - Page 8 Figure 4. Top View of Line Set Connections All refrigerant piping joints and connections in the EarthLinked® heating and cooling system, including the Auxiliary Cooling Module, line sets and earth loop system are to be brazed with 15% silver content brazing alloy, utilizing the NITROGEN BRAZING PROCESS.

Installation – Electrical and Start-Up ® 1. After turning “OFF” power to all EarthLinked and field supplied system components at the appropriate breakers remove the Auxiliary Cooling Module control box access panel. 2. Connect appropriately sized line voltage wires and ground wire to the Auxiliary Cooling Module, as shown in Figure 5. -
Page 10: Fan Speed Control
Installation - Fan Speed Control The Auxiliary Cooling Module (ACM) is equipped with a variable fan speed control that varies the speed of the fan as a direct function of the system condensing pressure. When the system is operating in cooling mode and the compressor unit turns on, the Auxiliary Cooling Module fan speed will increase as condensing pressure increases. - Page 11 Figure 7. Field Adjustment Procedure After adjustment has been made, install the sealing plug and replace and fasten the control panel cover prior to restoring power to the Auxiliary Cooling Module. The Auxiliary Cooling Module does not operate in heating mode. ACM-410CP-IM (05/13) Page 11...
