CAUTION
Use wet rags on either side of soldering points in order to dissipate heat. Use a
reflective plate (stainless steel) behind fittings when soldering in order to protect walls
from heat. Failure to observe precautions can cause equipment damage.
10. Remove grommet (Figure 6, Item 3) on rear hole of evaporator near 3/8-inch and 1/2-inch refrigerant pipes
before performing soldering procedures.
11. Solder evaporator 1/2-inch refrigerant pipe (Figure 6, Item 1) to existing 1/2-inch container refrigerant pipe
coupling (Figure 4, Item 2).
12. Solder evaporator 3/8-inch refrigerant pipe (Figure 6, Item 2) to existing 3/8-inch container refrigerant pipe
coupling (Figure 4, Item 4).
13. Solder evaporator 7/8-inch refrigerant pipe (Figure 7, Item 2) to existing 7/8-inch container refrigerant pipe
(Figure 3, Item 4).
14. Route temperature chart recorder sensor cable (Figure 9, Item 10) through cutout on forward side of evaporator
(Figure 9, Item 2) and pull sensor carefully into evaporator and install grommet in cutout.
15. Reinstall any insulation removed from piping to gain better access.
16. Connect evaporator return air sensor (Figure 9, Item 9) to evaporator return air sensor electrical connector
(Figure 9, Item 11).
17. Install evaporator cover (Figure 9, Item 7) onto evaporator hinged area.
18. Route temperature chart recorder sensor (Figure 9, Item 10) and return air sensor (Figure 9, Item 9) wiring
through evaporator cover (Figure 9, Item 7).
19. Mount return air sensor (Figure 9, Item 9) and temperature chart recorder sensor (Figure 9, Item 10) to cover
and secure with two tie wraps (Figure 9, Item 11).
20. Connect evaporator electrical connector (Figure 9, Item 1) to forward side of evaporator (Figure 9, Item 2) as
tagged. Remove tag.
21. Install ground strap (Figure 9, Item 4) to evaporator (Figure 9, Item 2) and secure using one screw (Figure 9,
Item 3), washer (Figure 9, Item 23), and nut (Figure 9, Item 24).
NOTE
Heating element wires are located inside the drain lines. The heating element wires
will have to be fed into the evaporator drain tubes.
22. Route two heating element wires through two elbows (Figure 9, Item 13) and install elbows on evaporator
(Figure 9, Item 2).
23. Carefully feed two heating element wires into two drain tubes (Figure 9, Item 12) on forward and aft side of
evaporator (Figure 9, Item 2).
