[C320-list] Adam's arrogance gets him in trouble

[Jane & Ken]

Adam,
   You must be certain that your unit does in fact use R-12 (freon) as the refrigerant.  The refrigerants--R-12, R-22, MP-39, 401-A, etc CANNOT be safely mixed.  That being said, it is "easy" to re-charge the system using a guage and a supply can of freon.
   If you have the same "The Cold Machine Installation and Operating Manual" dated 4/94 at the bottom left.  Page 2 has a picture of the 'typical completed installation'  at the top.
   Looking at the picture, move your finger one inch to the left and you should notice a black tube (line).  This is the inlet suction valve.The guage and supply freon attach there.
   If the unit is full and stable (not been running for 15-20 minutes) the pressure should be around 75 pounds--anything less will indicate a need to re-charge.
   With the supply and guage correctly connected, turn the unit on and verify that the compressor and fan are running.  Insert some freon just a little and close the supply to see what temperature is indicated on the guage---keep doing this until the teemperature is around -17 F.  The unit should now be okay for another several years unless the leak is getting worse.   Good Luck

Thank you very much.  I have the brochure that came with the unit and it
says that the unit was fully charged at the factory.  Where/how do you add
the R-12.

I thought I had controller problems years ago because the unit would cut off
in hot days.  Turned out to be a lack of ventilation at the compressor which
we remedied by adding some vent holes.  I was looking at the controller this
afternoon in a Defender catalog.  Amazing how it costs about 33% of an
entire new unit.

I am going to trying charging first and then see what happens.

Thank you for your guidance and advice.  It is very helpful.

Adam
