Page 28: Figure 16. Anode Wire Insertion
Strip the insulation from the multi-strand anode wire back approximately ¾ inch from the end and, while keeping the strands together, push the anode wire through the gland nut, gland cage, gland and plug body as shown in Figure 16. Loosen one of the two screw terminals on the plug insert to receive all of the strands of anode wire on one terminal. -
Page 29: Figure 17. Install The Plug Insert
Figure 17. Install the Plug Insert Slide the gland forward on the anode wire until it is firmly seated in the plug body as shown in Figure 18. Next, slide the gland cage over the gland, and slide the gland nut firmly against the gland cage, with the gland nut against the plug body. -
Page 30: Figure 19. Secure The Anode Wire
Once the gland nut has been hand tightened into the plug body, use two adjustable wrenches to further tighten the gland nut until it is snug in the plug body as shown in Figure 19 and the anode wire is held firmly in the plug body and will not slip out. Do not over-tighten the gland nut! Figure 19. -

Page 33: Start-Up Process
Start-Up Process System Leak Check CAUTION! During the Evacuation and Initial Charging processes, be sure that ALL ® power to the EarthLinked System is OFF. This includes the compressor unit, air handler and all other electrically powered system components. Failure to do so will cause lockout on start-up. After all indoor and outdoor refrigerant bearing components of the system have been installed and joints have been nitrogen brazed, pressurize the system prior to evacuation to leak test the system. -

Page 36: Evacuation
Evacuation Refer to Figure 26 and the following procedure: 1. Carefully vent any pressurized nitrogen charge from the compressor unit and system.. 2. After venting the pressurized system, use a good quality gage manifold and a non-permeable hose set as shown in Figure 26. If possible, use two Schrader core removal tools. Install one on the discharge line access port and the other on the initial charging port. -

Page 40: Final Charge
Final Charge 1. Remove the Schrader core tool from the hose just taken off of the initial charging port. 2. Crack open the LP valve on the manifold gage set so that a small amount of refrigerant gas flows to purge the hose. Connect the hose to the final charging port, shown in Figure 28. Tighten the hose to the final charging port and turn off the LP valve when the hose connection is secure. -

Page 60: Triple Evacuation
Triple Evacuation Triple evacuation is implemented to evacuate a system to a deep vacuum. It is accomplished by evacuating a system to a vacuum of 1500 microns, and then bleeding a small amount of dry nitrogen into the system. The nitrogen is then blown out to the atmosphere. The system is then evacuated until the vacuum is again reduced to 1500 microns.
