The drink machine at work keeps icing up the coil.
There is no auto defrost system, there is no
reason to need defrosting since the setting is
always above freezing.
I'm assuming it's low on refrigerant.
It has a charge port, appears to have been added.
We've had this machine about 10 years, never added
any before, so it must be a very slow leak.
I've never tried to add to a system this small. It
only holds 8 ozs. If I connect the gauges, won't I
loose so much removing the connections it will
change the amount left in the system? There is
only a port on the low side anyway...
The tag says it uses R12. How can I tell if it
still has R12 or has been changed to 134? Should I
just start over with 134? What about the
compatibility with the oil?
I have 1 can of R12. Don't want to waste it!
Thinking about just connecting it with a simple
hose with a ball valve and giving it a guess...
Any ideas?
Thanks!
