Line Set
Field refrigerant piping consists of liquid and suction lines
connecting the condensing unit and the indoor unit. Liquid
and suction service valves are located in a compartment at
the corner of the unit below the control box. Piping can be
routed directly from the service valves or field supplied
elbows can be added to divert the piping as required
Refer to table 1 for field-fabricated refrigerant line sizes for
runs up to 50 linear feet (15 m).
Table 1. Refrigerant Line Sizes for Runs
Up to 50 Linear Feet
Unit Liquid Line Suction Line
TPA 090 5/8” (16 mm) 1-3/8” (35 mm)
TPA 120 5/8” (16 mm) 1-3/8” (35 mm)
Refrigerant Line Limitations
You may install the unit in applications that have line set
lengths of up to 50 linear feet (15 m) with refrigerant line
sizes as outlined in table 1 (excluding equivalent length of
fittings). Size refrigerant lines greater than 50 linear feet
(15m or greater) according to the Lennox Refrigerant
Piping Design and Fabrication Guidelines (Corp. 9351-L9)
or latest version.
Electrical Connections
WARNING
Electric Shock Hazard. Can cause injury
or death.
Line voltage is present at all components
on units with single‐pole contactors, even
when unit is not in operation!
Unit may have multiple power supplies.
Disconnect all remote electric power
supplies before opening access panel.
Unit must be grounded in accordance
with national and local codes.
In the United States, wiring must conform with current local
codes and the current National Electric Code (NEC). In
Canada, wiring must conform with current local codes and
the current Canadian Electrical Code (CEC).
TRANSFORMER - 24VAC, 70VA - PROVIDED
NOTE — The addition of accessories to the system could
exceed the 70VA power requirement of the
factory‐provided transformer. Measure the system's
current and voltage after installation is complete to
determine transformer loading. If loading exceeds the
factory‐provided transformer capacity, a larger
field‐provided transformer will need to be installed in the
system.
