Refrigerant Piping
Units should be interconnected pre-
ferably by copper pipes.
The Table 04 presents connection
sizes for Onix units and remote
TRCE/TRAE condensing units, as
well as liquid and suction piping si-
zes recommended for the intercon-
nection.
The equivalent lengths indicated al-
ready include losses due to valves,
curves, elbows, reductions, etc.
Maximum Distances
(Recommended)*
Distance between units:
46m
Difference between unit levels:
18m
(*) – Calculated distance, considering equivalent
length of connection elements.
Contact
Trane
for distances above
the recommended ones.

Instructions for Fixing the Expan
-
sion Valve Thermostatic Bulb
- In the suction line, as closest as
possible to the evaporator outlet.
- Before external equalization, in an
horizontal line run.
Tab. 04 - Connection and Pipe Sizes Recommended by Circuit.
Note: For equivalent lengths above the values indicated, please contact Trane or an authorized installer.
- The copper tube must be comple-
tely clean.
- At the 12h position for pipes smal-
ler than 7/8”, and 4h or 8h position
for 7/8” or larger pipes.
- Then insulate the pipes using ther-
mal sheets.
