Figure 2. Auxiliary Cooling Module Refrigerant Connections
The Auxiliary Cooling Module has two refrigerant connections on the service side of the unit as
shown in Figure 2. The connections are the same size as each other. These sizes are listed in
Figure 2 for each Auxiliary Cooling Module model. Each connection is identified with a label saying
“To compressor” or “To earth loops”.
The refrigerant connections have caps brazed on at the factory. They should be un-brazed at the
time that tubing is to be connected to the Auxiliary Cooling Module.
After locating the Auxiliary Cooling Module as noted earlier, a trench 3 to 4 Feet deep is to be
excavated running from the Auxiliary Cooling Module to the earth loop line set. If the lines to and
from the Auxiliary Cooling Module are to be run parallel to and within 10 Feet of the building
foundation or basement wall, both lines are to be insulated with ½” wall thickness Armaflex

tubing insulation, cased within a 4” PVC pipe. The PVC pipe must be a minimum of 3
Feet from the building foundation or wall. This is illustrated for a typical application in Figure 3.
