Wall and Ceiling Troughs
Thermo King recommends enclosed wall or ceiling troughs be used for SPECTRUM multi-temperature applications.
Troughs not only protect refrigeration tubes and electrical harnesses from damage, but also help prevent air leakage
between compartments.
The following installation standards are recommended:
•
Only one trough (Wall or Ceiling) is required.
•
Refrigeration tubes should be routed neatly in the trough.
•
Refrigeration tubes should be secured by clamps every 600 mm (24.00 in.) inside the trough.
•
Electrical harness should be secured by clamps or tie bands every 600 mm (24.00 in.) inside the trough.
•
Insulate all hot gas and suction refrigeration tubes inside the trough.
•
Trough covers are recommended to protect refrigeration tubes and electrical harnesses from damage.
