These are what is called a critical charge system, please note the word critical there!
Step 1 - Clean coils, ensure condenser is clean, and evaporator is clean.
Step 2 - recover all gas in system, then pull a 1000 to 500 micron vacuum for an hour
Step 3 - it will take exactly 2 cans of redteck 12a (32 ounces equivalent) if set up for the original R12
Step 4 - run unit for a while and observe suction line pressure and monitor clutch it should disengage at apxly 32f equivalent pressure, if it does not then the low side switch will need to be replaced / adjusted
this is off memory while tired, but this will get you in the general area.
