Then as long as you use the proper gas with the specific compressor you should be okay.  A properly charged and operating soda cooling unit should run between 18 and 20 lbs on the low side.

If my deck does have to be rebuilt, Where do you live at and how much would it cost me? (I am planning on selling this one)

Or if it works better than my Dixie Narco SIII (which is war out) then I will swap it.

The evaporator fan is the one inside the cabinet under the delivery chute and should be running all the time.  The fan in front of the compressor is the condenser fan and it only runs when the compressor is running.  There is a 3 minute or so delay after closing the door before the compressor will start.  The compressor also turns off when opening the door.  These events occur to prevent moisture from freezing on the evaporator due to condensation by opening the door.

OK. Thanks. Im not familar with Royal machines.

So I need to close the door and wait 3 minutes and the compressor will kick on?

That was built in the 3rd quarter of 1998.

Thanks.

That is an automotive brand of R12 and I wouldn't recommend it for true refrigeration work.  It sounds like you want to recharge this yourself, but if you aren't a qualified and certified refrigeration technician I would advise you to find someone who is.  You don't want to break the law or damage your cooling systems because you don't know what you're doing.  This type of work must be done by someone with proper gauges, proper recovery and recharging equipment, a certified knowledge of how refrigeration works and how to service it and who will stand behind their work.  The wrong techniques can ruin a cooling system. 

Ive done Auto A/C systems....

You would need to cross over the model of compressor on the machine now to whatever you can get locally, but it must be an R12 compressor.  Again, you can't put 134A into the R12 compressor and you don't want to put an R134A compressor on your system because you already have the oil from the R12 all throughout your system.  You don't want to contaminate the system with a different oil.

Can I put Freeze 12 in it?
