Refrigerant Screen
During manufacturing, service, and repair there is always the
potential for debris to accidentally enter the sealed refrigeration
system. Filter screens are positioned around the refrigerant
circuit to prevent any possible debris from entering critical
components; expansion valves, compressors, etc. These
screens are not bi-direction and must be installed in a specific
direction if replaced. Please be aware that these screens are
not desiccant filters and provide no moisture protection for
compromised systems.

Indoor Expansion Valve
The Indoor Expansion Valve (EVI) is a 12 VDC stepper motor
driven valve. In cooling mode EVI is used to control the
superheat and expand the refrigerant entering the Indoor Coil,
operating as an evaporator, in much the same way as a TXV
on a conventional air conditioner.
