REPLACE CONTINUED
NOTE
The accumulator will need to be loosened from its mounting position in order to gain
the needed movement in the tubing to be de-soldered so that the joint can be
separated. The entire accumulator will not have to be removed, just the mounting
hardware securing it to the refrigeration unit chassis.
10. Remove mounting nut (Figure 1, Item 13) and washer (Figure 1, Item 14) from bottom of accumulator (Figure 1,
Item 15) to facilitate separation of tubes during desoldering operation.
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
component to be soldered in wet rags will act as a heat sink and minimize exposure
to heat. Excessive heat will damage the valve assembly.
NOTE
Before desoldering the CPR valve, make sure to note the orientation of the valve on
the piping as installed so that the replacement valve can be installed in the same
position and orientation.
11. Desolder one end of CPR valve (Figure 1, Item 6) flared fitting joint from suction vibrasorber (Figure 1, Item 7).
12. Desolder one end of CPR valve (Figure 1, Item 6) from 1 1/8-inch suction tube (Figure 1, Item 8) at flared fitting
(Figure 1, Item 6).
13. Remove CPR valve (Figure 1, Item 6).
14. Solder one end of new CPR valve (Figure 1, Item 6) to 1 1/8-inch suction tube (Figure 1, Item 8) leading into
accumulator.
15. Solder other end of CPR valve (Figure 1, Item 6) into suction vibrasorber (Figure 1, Item 7).
WARNING
Piping will remain very hot following soldering procedures. Make sure to wait long
enough for pipes to cool before performing maintenance or attaching clamps.
16. Install mounting nut (Figure 1, Item 13) and washer (Figure 1, Item 14) to secure accumulator (Figure 1,
Item 15) to chassis.
17. Install both halves of saddle clamp (Figure 1, Item 12) and secure CPR valve to frame using two bolts (Figure 1,
Item 9), washers (Figure 1, Item 10), and nuts (Figure 1, Item 11).
18. Install clamp (Figure 1, Item 5) over CPR valve (Figure 1, Item 6) and secure to mounting plate using one screw
(Figure 1, Item 1), new lock washer (Figure 1, Item 2), washer (Figure 1, Item 3), and nut (Figure 1, Item 4).
