2. All series Earth Loops: V1, D1, T1, V1.5, D1.5, V2, D2, D3, H1, H5 3. ACMs are for CC, SC, SD, SCW and SW compressor units only. ® Note: Desuperheater and all EarthLinked thermostats can be utilized throughout capacity range. Figure 1. Model Numbers Guidelines for the general layout of the system components are shown in Figure 2. -
Page 4: Placement & Mechanical Information
Figure 2. General System Layout Placement ® EarthLinked compressor units may be located outside or inside the building, following these guidelines. OUTSIDE Locate compressor unit: • On a standard HVAC condensing unit pad, resting on firm, level, settled ground. •... - Page 5 • For SD compressor units (which have potable domestic water connections) where the surrounding air temperature remains above 40°F. • Where suggested clearance is 3 feet on both sides, top and front, for access. However, local codes and applicable regulations take precedence. Clearance from back panel to wall and minimum side clearance should be at least one foot.
- Page 6 Compressor units are shipped from the factory with a low pressure nitrogen holding charge. Carefully relieve the holding charge when the compressor unit is being prepared to connect refrigerant system piping. The compressor unit package contains a service valve kit and an adapter kit. The two service valves are to be installed on the earth loop vapor and liquid connections of the compressor unit, using the adapters to right-size to the proper earth loop line set.

System Start-up Evacuation/Charging 1. SC, SD, SCW, HC, HCW, HW and HWW Models Refer to Figure 20 and the following description: a. Seal Test Evacuation and Initial Charge 1. Carefully vent the nitrogen charge from the compressor unit. 2. After installing and nitrogen brazing the HVAC system components and compressor unit service valves, turn the service valves “OFF”... - Page 26 6. Initiate the system evacuation. Evacuate the system down to 230 MICRONS as read on the digital micron gage. After 230 microns has been achieved, turn off the LP and HP valves and turn “OFF” the vacuum pump. Reading the digital micron gage, the system pressure must not exceed 280 MICRONS WITHIN 5 MINUTES.
