REPLACE CONTINUED
NOTE
Due to the fragile nature of the accumulator neck flanges and the tight workspace
needed for desoldering the connections to the accumulator, the accumulator will be
removed with piping attached and placed on a work bench for desoldering piping
from the accumulator. Piping removed will be reused on the new accumulator and
soldered back onto the new accumulator before installing it into the refrigeration unit.
8. Remove two screws (Figure 2, Item 1), lock washers (Figure 2, Item 2), washers (Figure 2, Item 3), and nuts
(Figure 2, Item 4) securing 3/8-inch refrigerant pipe clamp (Figure 2, Item 5) and CPR valve clamp (Figure 2,
Item 6) to clamp mounting plate (Figure 2, Item 7) near CPR valve (Figure 2, Item 8). Discard lock washers.
9. Remove 3/8-inch refrigerant pipe clamp (Figure 2, Item 5), CPR valve clamp (Figure 2, Item 6), and clamp
mounting plate (Figure 2, Item 7). Retain for reinstallation.
10. Remove one screw (Figure 2, Item 9), lock washer (Figure 2, Item 10), washer (Figure 2, Item 11), and nut
(Figure 2, Item 12) securing two clamps (Figure 2, Item 13) to two refrigerant pipes (Figure 2, Item 14) at filter
drier (Figure 2, Item 15) inlet. Discard lock washer.
11. Remove two clamps (Figure 2, Item 13) at filter drier (Figure 2, Item 15) inlet. Retain for reinstallation.
12. Remove one screw (Figure 2, Item 16), lock washer (Figure 2, Item 17), washer (Figure 2, Item 18), and nut
(Figure 2, Item 19) securing two clamps (Figure 2, Item 20) to two evaporator refrigerant pipes near filter drier
(Figure 2, Item 15) inlet. Discard lock washer.
13. Remove two clamps (Figure 2, Item 20) near filter drier (Figure 2, Item 15) inlet. Retain for reinstallation.
14. Loosen 3/8-inch refrigerant pipe fitting (Figure 2, Item 21) from filter-drier (Figure 2, Item 15) outlet.
15. Remove 3/8-inch refrigerant pipe (Figure 2, Item 21) from filter-drier (Figure 2, Item 15) outlet.
16. Cut 1/2-inch refrigerant pipe (Figure 2, Item 14) leading to evaporator vibrasorber (Figure 2, Item 22) at cut
location (Figure 2, Item 23).
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.
CAUTION
Use care when soldering and desoldering components into the system so as not to
overheat the component being soldered or surrounding components. Wrapping the
components to be soldered in wet rags will act as a heat sink and minimize exposure
to heat.
17. Wrap CPR valve (Figure 2, Item 8) with wet rags to serve as a heat sink and use a heat shield where required
in order to protect surrounding components, hoses, and/or wiring.
