1. All joints to be soldered must have proper fit.
Clearance between tubes to be soldered
should be from .001” to .006”. It is not
practical to actually measure this; however,
you do not want a dry fit or loose fit. Tubing
joints should overlap about the distance of
their diameter except for restrictor tubes,
which should be inserted 1.25”.
2. Clean all joint areas with fine steel wool or
preferably an abrasive cloth, such as grit cloth
No. 23 or Scotch-Brite.
3. Apply a thin film of liquid flux recommended
for silver soldering to surfaces to be joined and
to surfaces immediately adjacent to joint.
4. Align tubing so no stress is on joint. Do not
move tubing while solder is solidifying or leaks
will result.
5. Use a torch of adequate capacity so joint can
be quickly heated with a minimum of heat
travel to other points. Use a good grade of
silver solder.
6. Solder connections. If tubing is properly
cleaned and fluxed, solder will flow readily.
Use only enough solder to make a good bond.
7. Allow joint to cool, then wash exterior with
water to remove flux.

The basic components of a refrigerator are a
compressor, condenser, evaporator, heat
exchanger (capillary tube and suction line), drier
and perimeter hot tube.

To reduce the possibility of condensation forming
on the exterior of the cabinet in high humidity
areas, a perimeter hot tube (refrigerant tube) has
been installed in the unit. The perimeter tube
extends up the left side,across the top of the
freezer and down the right side into the filter drier.
When the compressor operates, warm refrigerant
flows through the primary condenser, then into the
primary hot tube, warming the cabinet front
exterior.
The perimeter hot tube is not replaceable. In the
unlikely event of a leak in the hot tube, a kit is
available to bypass the hot tube in the sealed
system. An electrical heater wire must be installed
within the tubing. Refer to the appropriate parts list
of the model being serviced for the correct kit part
number.

The refrigerant cycle is a continuous cycle that
occurs whenever the compressor is in operation.
Liquid refrigerant is evaporated in the evaporator
by the heat that enters the cabinet through the
insulated walls and by the heat from product load
and door openings. The refrigerant vapor is then
drawn from the evaporator, through the suction line
to the compressor. Compression raises the
pressure and temperature of the vapor in the
compressor and the vapor is then forced through
the discharge valve into the discharge line and into
the condenser. Air passing over the condenser
surface removes heat from the high pressure vapor
which then condenses to a liquid. The liquid
refrigerant then flows from the condenser to the
evaporator through the small diameter liquid line
(capillary tube). Before it enters the evaporator, the
liquid refrigerant is sub-cooled in the heat
exchanger by the low temperature suction vapor in
the suction line. When refrigerant is added, the
frost pattern will improve, the suction and
discharge pressures will rise, the condenser will
become hot and the wattage will increase.
