18. Desolder 1-1/8-inch refrigerant pipe (Figure 2, Item 24) between accumulator (Figure 2, Item 25) and CPR valve
(Figure 2, Item 8) at flared fitting (Figure 2, Item 26) location.
19. Use a heat shield where required in order to protect surrounding components, hoses, and/or wiring, and
desolder 1-1/8-inch pipe (Figure 2, Item 27) from accumulator (Figure 2, Item 25) at elbow (Figure 2, Item 28).
20. Remove one nut (Figure 2, Item 29) and one washer (Figure 2, Item 30) securing accumulator (Figure 2, Item
25) to refrigeration unit chassis.
21. Carefully remove accumulator (Figure 2, Item 25) with refrigerant piping attached from refrigeration unit and
place on a work bench.
CAUTION
If using a vise or clamps to hold the accumulator in place during desolder or solder
operations, use care so as not to damage the accumulator.
NOTE
It is important to note the direction of the piping coming out of the accumulator before
desoldering and install the piping into the new accumulator with the same orientation
so that the accumulator will fit back into the refrigeration unit, and piping will align
with existing refrigeration unit piping.
22. Remove insulation as required from accumulator piping. Retain for reinstallation.
WARNING
Many of the chemicals used while soldering are toxic. Avoid prolonged exposure to
fumes. Wear rubber gloves and eye protection. Failure to wear proper protective
clothing may result in skin irritation and/or serious eye injury. Wash hands with soap
and water after handling solder. If inhaled, move soldier to fresh air and seek medical
attention. If contact with skin or eyes is made, wash with clean water and seek
medical attention.
23. Desolder one 3/8-inch refrigerant pipe (Figure 3, Item 2) from accumulator (Figure 3, Item 3). Retain pipe for
reinstallation.
24. Desolder one 1/2-inch refrigerant pipe (Figure 3, Item 1) from accumulator (Figure 3, Item 3). Retain pipe for
reinstallation.
25. Desolder two 1 1/8-inch refrigerant pipes (Figure 3, Item 4 and Item 5) from accumulator (Figure 3, Item 3).
Retain pipes for reinstallation.
26. Refer to Figure 3 and temporarily install piping into new accumulator without soldering piping to accumulator.
27. Temporarily install new accumulator into refrigeration unit in order to fit-check piping alignment before soldering.
28. Make any needed piping alignment changes with accumulator in place to align with refrigeration unit piping.
