LOKRING METHOD
Lokring is a method to install the evaporator in the freezer
without using a torch. It uses a mechanical connection
instead of a soldered connection. Apply a few drops of
LokPrep (a special cleaning solution and seal) to the
terminals of the pipe you wish to join. The Lokring tool
compresses the connector to ensure a tight mechanical
connection. The parts shown on the right are required to
use the Lokring replacement method.
For additional information on how to use the Lokring, call
1-800-848-7722 & order publication # 31-9067 (Lokring
Repair Procedures Manual) and Publication # 31-9066
(VHS Video Cassette Lokring Repair Procedures)
HEAT PROTECTOR METHOD
The heat protection kit is used to prevent damage to the
refrigerator liner when soldering the evaporator in the
sealed system. See the instructions included in the heat
protection kit. The kit comes with enough heat absorbing
paste, soldering iron and adhesive to finish four repairs.

There are two approved methods to change the evaporator. The
Lokring method does not require welding, since it uses tight
mechanical connections. The heat shield uses the traditional
soldering method, but gives protection to the upper liner while
welding the evaporator connections in the freezer compartment.
Always add a new drying filter when repairing the sealed system.
Follow each step of the instructions included with the evaporator
replacement.
