Installation – Refrigerant Connections

The Hybrid Cooling Module has two refrigerant connections on the service side of the unit as

shown in Figure 1. Each connection is 7/8". Each connection is identified with a label saying

"Compressor" or "Earth loops". Check Figure 1 and the table on page 4 to determine coupling

sizes to match the line set vapor tube size.

The Hybrid Cooling Module is factory charged with dry nitrogen. Relieve

the nitrogen from the system by means of the Schrader valve located on

the compressor unit connection and/or earth loop connection shown in

Figure 1.

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 Hybrid Cooling Module.

After locating the Hybrid Cooling Module as noted earlier, a trench 3 to 4 feet deep is to be

excavated running from the Hybrid Cooling Module to the earth loop line set. If the lines to and

from the Hybrid 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 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.
