Refrigerant Coil Piping
Note:
Refer to the
“Responsible Refrigerant Practices!” section on page 2
for information on
handling refrigerants.
Use
Figure 54
to determine the proper, relative sequence of the components in the refrigerant lines
that connect the condensing unit to an evaporator coil. Refer to
“Examples of Field-Installed
Evaporator Piping” on page 60
for more detailed schematics of evaporator piping.
See SS-APG002-EN Application Guide: Tube Size and Component Selection for TTA and TWA Split
Systems and SS-APG001-EN Application Guide: Tube Size and Component Selection for RAUC
Split Systems for more information.
