SV KIT INSTALLATION
1. After ensuring the compressor unit and earth loop line set has no refrigerant or nitrogen holding
charge, and after power has been turned “OFF” to the compressor unit and all other
EarthLinked® and field supplied system components (at the appropriate breakers), remove the
front and top panels of the compressor unit cabinet.
2. Within the compressor unit, locate the charging port on the earth loop liquid line. Remove the
core and connect a nitrogen tank hose to the charging port, which will be used later to purge the
earth loop system of oxygen.
3. Cut the VAPOR line in convenient proximity to the compressor unit, as shown in Figure 2. The
line should be cut squarely, maintaining the roundness of the tube ends. Deburr the cut ends
and clean the cut ends of the tubing.

4. Adjust the VAPOR service valve so it is in the “open” position. Remove the service port core
from the valve. Clean the inside of the service valve line set ports and
insert the line set
tubing into the service valve so the service port is on the earth loop side of the valve.
See Figures 3 and 4.
