REPLACE CONTINUED
23. Install fitting (Figure 4, Item 4) in new valve (Figure 4, Item 1).
24. Align replacement valve assembly (Figure 4, Item 1) into accumulator.
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, flush with clean water and seek
medical attention. Failure to observe this warning may result in serious injury to
personnel.
CAUTION
Before soldering, be sure that suction service valve can be installed into the saddle
clamps. This is critical to the life of the valve.
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.
25. Solder suction service valve (Figure 4, Item 1) assembly at joint (Figure 4, Item 2) coming off of CPR valve
(Figure 4, Item 3) and fitting (Figure 4, Item 4) on CPR valve before accumulator.
NOTE
When installing insulation, do not cover portion of valve that was soldered during this
procedure until leak check has been completed.
26. Install insulation onto suction service valve tubing from accumulator to CPR valve.
27. Place suction service valve assembly into refrigeration unit.
28. Install nut (Figure 3, Item 1) and washer (Figure 3, Item 2) on bottom of accumulator to secure accumulator to
refrigeration unit chassis.
29. Clean surface area of compressor prior to installing a new gasket. Be sure all cables are secured out of the way
using wire ties.
30. Install rear portion of both saddle clamps (Figure 5, Item 19 and Item 20) behind tube locations.
31. Install new suction service valve (Figure 5, Item 10) and gasket (Figure 5, Item 18) onto compressor and
temporarily secure in place using four bolts (Figure 5, Item 16) and four washers (Figure 5, Item 17). Do not
tighten bolts at this time.
32. Install saddle clamp cap and spacer (Figure 5, Item 9) over suction tube and secure using two bolts (Figure 5,
Item 6), washers (Figure 5, Item 7), and nuts (Figure 5, Item 8).
33. Install saddle clamp cap and spacer (Figure 5, Item 4) over suction tube and secure using two bolts (Figure 5,
Item 1), washers (Figure 5, Item 2), and nuts (Figure 5, Item 3).
