Hi people I wanted to know if it is possible to change the r134 for the yh12 xq I have only yh12

HELLO FRIEND, IT IS NOT POSSIBLE WITHOUT CHANGING THE REST OF COMPLEMENT. WE LEAVE THE SIMILAR COMPRESSOR: NOW YOU'LL HAVE TO CHANGE THE CAPILLARY AND OF course FILTER. AND THE AUTOMATIC CUTTING PROBABLY ALSO DID NOT BE THE SAME COLD. EL 134 IS COLDER THAN 12. AND AN ACCORDING OIL. IN MY HUMBLE OPINION, TRY TO GET THE 134 THAT UNTIL YOU GET IT IN THE FREE MARKET AND SEND IT TO ANYWHERE. REGARDS .

Hi Naza, I commented the YH12 I have used it for many years I never had problems is more similar to R409A with an evaporation temperature of -31 ° C a little cooler than 134 or mp39 is an HCFC gas and the recommended oil It is Alkylbenzene but it works well with mineral oil and can also be used in Poe oil but many say no, I used it and it never brought me problems PEEEROOOO is safer if you change the oil poe to AB. And on the other hand you must charge in liquid phase since it is a mixture of gases, with respect to the capillary of the refrigerator because in some cases I worked well without touching capillary and in others I had to shorten capillary since for 134 it is longer than for r12 but I tell you that although rarely happened to me there were teams that did not work as expected and I had to put yes or yes r134 although it is not a gas of my liking. The 134 works very well just be careful with moisture and a very good replacement for 134 and r12 is the ISCEON MO 49 plus that is used for all oil. good luck

Put the MP39 without changing anything, it will work perfect for you, I will do it for years, but unfortunately in my place of origin, there is no longer the MP39, r12, pure r134a hehe, greetings and luck.
