Refrigerant Line Connections
The EarthWise™ purge liquid separator requires three
refrigerant connections:
1. Vapor connection between the purge liquid separator
and the purge suction gas line.
•
Install a 5/8” “T” in the purge vapor line which runs
from the chiller condenser to the purge tank (see
). Install 5/8” copper tubing from the “T” to
the liquid separator. Slope the line to allow any
refrigerant to drain into the liquid separator.
2. Liquid return connection from the liquid separator to
the moisture indication sight glass.
•
Install 3/8” copper tubing from purge liquid separator
to the sight glass.
3. Liquid return connection from the liquid separator to
the chiller evaporator.
•
Install 3/8” copper tubing from the purge liquid
separator to an access valve on the chiller evaporator.
Maintain a minimum two inch per foot pitch toward the
evaporator.
Maintenance
Routinely check the purge moisture indicating sight glass
and change the filter drier as necessary. It is important to
maintain the chiller’s refrigerant charge in a dry condition.
