CHAPTER 2. ATTENTION WHEN REPAIRING
[1] HOW TO REPAIR REFRIGERATION
[1] HOW TO REPAIR REFRIGERATION
Before sealed system work can be preformed a refrigerant recovery EPA and LOCALLY approved certication is required,
additionally, EPA and LOCALLY approved refrigerant recovery equipment is required.
1. Sealed system repair
Sealed system repairs should be properly diagnosed before
entering into a repair of the system.
It is important to follow proper procedures when doing a system
repair for safety reasons and that the repair will result in a
restoration of the system to proper factory standards.
2. Safety reminders
1) Do not heat any system component with an open ame for
any reason.
2) Do not solder until you are sure that all refrigerant has been
removed from the system.
3) Do not heat the charging cylinder with an open ame. Use
warm water only and do not exceed 125 F (not too hot to keep
your hand in.)
4) Do not over ll any charging cylinders, as they could explode
when over lled.
5) Use proper wrenches.
6) Use safety goggles when working with refrigerants.
7) Keep a re extinguisher within easy reach.
8) Watch ame direction when soldering so as not to burn
clothing, wiring or other components.
9) Solder in a well ventilated area. If a high concentration of
freon is present, an open ame will create phosgene gas which
can be harmful.
3. Proper soldering
Joint clearances should be maintained so that the brazing alloy
will ow between the closely mated surfaces rather than forming
large llets.
This lms make the strongest joints, capillary attraction also work
best with close tolerance.
The best clearance is between 0.01" to 0.03", the amount of lap
will be approximately 3/8" depending on the swaging tool used.
4. Cleaning tubing
To make a sound, leak tight joint, the brazing alloy when raised
to brazing temperature, must wet and ow freely over the entire
surface of the tubing in the joint area.
To assure this, the tubing surfaces must be free of all dirt,
grease, oil and oxides otherwise the alloy will not wet and ow
properly over any surface with these elements present. Cleaning
can be done with an abrasive cloth or steel wool. Never blow
into the tubing because this will introduce a lot of moisture into
the system. Open tubing joints should be covered if exposed for
long periods of time.
5. Proper uxing
Flux is necessary when using silver solder; it is not required
when using silfos on copper to copper joints.
To do a good job the ux should cover the tube surface
completely. Be careful not to introduce any ux inside the tubing.
Fluxing should be done after the tubing is mated together and
just before brazing is done. Do not allow it to dry out.
When brazing, the ux should become entirely liquid and clear,
like water. The temperature will be at 1100 F and only a little
more heat will allow the alloy to ow freely into the joint.

6. Heating the tubing
Direct the torch ame so that the larger tube receives most of the heat.
Silver solder ows at 1200 F and silfos ows at 1300 F.
Heat all around the tubing.
The ame is composed of two cones, a smaller inner cone (pale blue)
in calor and a much larger outer cone. The hottest part of the ame is
at the tip of the inner cone. The ame should be directed at the joint
with the tip of the cone just touching the surface of the tubing.
7. Dehydrating sealed system
Many servicers feel that since air conditioners run with evaporator temperatures above 33 F, moisture will not present a problem.
Nothing is further from the truth. Oxygen in moisture plus the heat produced during compression will react with the refrigerant oil to
produce harmful acids in the system which will break down motor winding insulation, create sludge and pit component parts, reducing
efciency of the air conditioner and shortening the life of compressors.
There it becomes mandatory that good dehydrating practices be adhered to at all times.
Proper hook up procedures as shown in Figure 5 must be used in order to pull and good vacuum from the system.
The use of a good vacuum pump is very important so that the boiling point of any water in the system will be lowered to a point where
it will vaporize and be expelled from the system in the form of vapor.
7.1. Type of evacuation methods
1. Piston Type Compressor No good.
System parts must be above 110 F.
2. Rotary Vacuum Pump Disavantages.
Low CFMC. 4 oil gets dirty.
3. Single State Vacuum Pump will not clean oil.
Oil must be changed often.
4. Two Stage Vacuum Pump will reach 50 microns.
First stage is below atmospheric pressure.
Moisture is removed into second stage which works up to atmospheric
pressure thus keeping oil clean.
Manometer cannot be read to 1/2 mm. Micron gauge reads from
25,400 microns to 0.
It becomes clear that good equipment and maintained properly must be used in order to remove air and moisture from the system.
When a vacuum of 1,000 to 500 microns is reached, block off the vacuum pump from the system.
This is done by closing the value between the pump and system. If the micron gauge does not increase above 1,000, the system is
free of moisture and no leak exists. If the micron gauge increases to higher levels moisture or a leak exists.

8. Leaks
Several methods are used to detect leaks in systems.
● Electronic Leak Detectors are very sensitive and are able to detect leaks down to 1/2 ounce per year.
A good electronic leak detector is generally far better in locating very small leaks.
● Halide Torch be sure the room is free from refrigerant vapours. Watch the ame for the slightest change in calor.
A very faint green indicates a small leak. The ame will be unmistakably changed to green or purple when large leaks are encountered.
To simplify leak detection pressurize the system to approximately 75 lbs.
Some leaks can be located by a visual inspection of the system components and solder joints and if oil is found at any given location it
generally is a sign that a leak exists at that point due to the fact that ame does carry oil with it travels through the system.
● Soap Bubbles
Liquid detergents can sometimes assist in nding small leaks by brushing detergent on the suspect area and watching for bubbles.
Before applying detergent be sure that the system is pressurized.
Tap line devices are permissible for diagnosis only they are not suitable when evacuating the system. After the diagnosis has been
made they must be removed so that the system will be restored to a hermeticly sealed condition.
