Refrigerant Line Connections
The EarthWise™ purge liquid separator requires three
refrigerant connections:
1. Vapor connection between the purge liquid separator
and
the purge su
ction gas line.
• Install a 5/8” “T” in the purge vapor
line which runs
from the chiller condenser to the purge tank (see
Figure 16 ). 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
th
e moistu
re indication sight glass.
• Install 3/8” copper tubing from purge liquid separator
to the sight glass.
3. Liqu
id return connection from the liquid separator to
the chiller evaporator.
• I
nstall 3/8” copper tubing from the purge liquid
se
para
tor 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.
