ELECTRICAL WIRING REPAIR - GENERAL.
This task covers:
Refrigeration Unit Service Tool Kit
Soldering Gun Kit
Use disconnect switch (NOT POWER
CABLE) to disconnect power to unit.
Damage to cable connector pins will

result it cable is used.
Disconnect power at power source.
Wire connections must be made mechanically sound before they are soldered; solder alone does not
provide sufficient strength to prevent breakage. Joining surfaces of connections to be soldered must
be clean and bright. Flux should be brushed onto the joint before soldering. Wires should always be
heated to the point at which the solder will melt completely and flow into all parts of the joint. Excessive
build-up of solder "gobs" on the joint should be avoided or removed.
(2) Insulating Joints.
The preferred method of insulating electrical joints is by the use of heat-shrink tubing. To apply, cut a
piece of heat-shrink tubing of suitable diameter to a length of 1 inch (2.5 cm) for covering joints at
terminals or connectors, or to a length about 1/2 inch (1.3 cm) longer than the joint to be insulated.
Slide the tubing over the wire before making the joint. After the joint is made, slide the tubing so that it
rovers the joint, and shrink in place with moderate heat.
