NOTE
The temperature chart recorder power cable and sensor cables will need to be pulled
through the cutouts in the hinged mount bracket when removing the temperature
chart recorder.
17. Remove chart recorder (Figure 4, Item 3) and attached cable (Figure 4, Item 7 and Item 8) from hinged mount
bracket (Figure 4, Item 2).
NOTE
A new temperature chart recorder will come with both temperature chart recorder
sensor cables and a power cable already attached. The temperature chart recorder
sensor cables will be completely removed from the MTRCS for each evaporator and
remain attached to old temperature chart recorder when removed. Steps 22 through
28 are to be performed for each evaporator temperature chart recorder sensor.
18. Feed power cable (Figure 4, Item 7 and Item 8) through cutouts in mount bracket (Figure 4, Item 6) and install
new chart recorder (Figure 4, Item 3); then secure using two bolts, (Figure 4, Item 4) and new lock washers
(Figure 4, Item 5).
19. Feed new sensor (Figure 5, Item 5) and cable through container feed through by pushing sensor end through
container pass through from outside container wall to inside container wall (Figure 6, Item 5).
20. On inside of container, carefully pull sensor (Figure 5, Item 5) and cable through until enough is through to mount
sensor on evaporator cover (Figure 5, Item 3).
21. Carefully pull return air sensor (Figure 5, Item 4) and temperature chart recorder sensor (Figure 5, Item 5) through
hole in cover (Figure 5, Item 3).
22. Mount return air sensor (Figure 5, Item 4) and temperature chart recorder sensor (Figure 5, Item 5) to cover and
secure with two tie wraps (Figure 5, Item 6).
23. Install tie wraps (Figure 5, Item 6) as needed from mount location forward to where sensor cables pass through
container wall while removing slack in cables as needed.
24. On outside of container, secure temperature chart recorder sensor cables using tie wraps up to point where
cables enter temperature chart recorder feed through (Figure 5, Item 9).
