The EG4 Line Set Extension Kit offers an extra 16.4 feet (5 meters) of lines for your EG4 mini-split air conditioning unit. This extension is ideal when the standard 16.4 ft. (5m) lines provided with the mini-split are insufficient. Both the line sets in this kit and those with the EG4 mini-splits come pre-vacuumed and feature Plug-N-Cool connectors. Additionally, the kit includes connectors to link the Plug-N-Cool line sets together without needing an HVAC professional.*
*3 percent efficiency reduction without adding refrigerant
Adding a line set extension increases the system's volume, potentially causing around a 3% efficiency drop per additional line set. To offset this, a certified HVAC technician can introduce refrigerant (.2 oz./ft.) into the system.
The line sets in this kit and those with the EG4 mini-splits are pre-vacuumed and equipped with Plug-N-Cool connectors
Line set extensions should be installed during the initial setup of the indoor and outdoor units. This extension kit is not designed to lengthen the line sets of a system that has already released refrigerant by opening the outdoor unit's refrigerant valves.
