Loading and Enroute Inspections

Single Temperature Loading
Procedures
Additional steps must be taken to insure load temperature
requirements are implemented and maintained when a
multi-temp unit is used to refrigerate a single-temperature load.
Trailer loading procedure will be different depending on how
temperature control has established for each trailer
compartment Zone. See “Operating the Unit in Single Zone
Mode” in the Operating Instructions chapter in this manual.
Figure 2: Two Compartments, Same Setpoint
Temperature, Bulkheads In Place
In the example in Figure 2, each Zone could be individually set
to 35 F. The evaporator in each compartment will then control
the temperature in that compartment to the same 35 F setpoint.
NOTE: Using the above method, it is recommended that the
bulkheads that separate each compartment be in place to
isolate the compartments.
Figure 3 shows two Zones that have the same setpoint. The
bulkhead separating the compartments has been removed. The
Host evaporator senses temperature and controls both
evaporators to the temperature setpoint.

Temperature, Bulkhead(s) Removed
NOTE: Using Method 2, it is recommended that all
bulkheads be removed to create one large compartment.
