Refrigerant Charge - GE ETS22 Technical Service Manual

6. Remove the 2 screws that hold the
evaporator to the cabinet.
Caution:
• If desoldering the evaporator, heat shield,
P/N WR49X10025, must be used to
prevent damage to freezer liner.
• Protect wiring from heat during
desoldering and resoldering.
• To prevent damage to the capillary tube,
the capillary tube must be desoldered
first.
7. Desolder the capillary tube from the
evaporator.
8. Desolder the suction line. Use a pair of pliers
to hold the evaporator.
9. Remove the evaporator.
10. Using a file, score the capillary tube just above
the old solder and break the solder-covered
section off. This will help prevent the capillary
tube from becoming plugged when
resoldering.
11. Position the new evaporator in the cabinet.
Insert the suction line and capillary tube into
the evaporator.
12. Solder the suction line to the evaporator
using silfos.
13. Solder the capillary tube to the evaporator
using silfos.
Note: Heat probe assists in defrosting drain.
During assembly, probe must be installed on
evaporator and in drain to prevent drain from
freezing closed.
14. Install a replacement dryer.
15. Evacuate and recharge the system using
currently accepted procedures.
Evaporator (LOKRING Method)
1. Recover the refrigerant.
2. Remove the evaporator cover.
3. Remove the defrost thermostat.
4. Remove the defrost heater.
5. Disconnect the ground wire from the
evaporator and position all wiring to allow for
evaporator removal.
6. Remove the 2 screws that hold the
evaporator to the cabinet.
Caution: Tubing must be clean and free from
burrs when using LOKRING.
Note: LOKRING connector, P/N WR97X10021
must be used. Two LOKRING connectors P/N
WR97X10021 are required.
7. Replace the evaporator using the LOKRING
method (see Pub #31-9067).
• Cut the copper lines of the old evaporator
as close as possible to the aluminum
evaporator tubes.
• Cut the copper lines of the new evaporator
1-1/8 in. from the edge of the aluminum
evaporator tubes.
• Defrost thermostat can be moved from the
horizontal part of the copper line to the
vertical part, just above the bend.
Note: Heat probe assists in defrosting drain.
During assembly, probe must be installed on
evaporator and in drain to prevent drain from
freezing closed.
8. Install a replacement dryer.
9. Evacuate and recharge the system using
currently accepted procedures.
