Toshiba compressor kfr33 help please
Hi I have just purchased a kfr-33 toshiba compressor split system ,
These units are sold as easy fit for DIY instilation
I have installed as per instruction book but have now discovered that there is no real way of evacuating the lines without a vac pump , the instructions tell you to open the small pipe valve for 4-5 secs then close , look for leaks then push the large pipe valve with a screwdriver to expel pipe work for 3-4 seconds , then fully open both and run unit ,
My question is if I get a installer to pump down the 410a into the compressor and close both valves then vac the lines is that going to help of has the damage already been done ?
Look forward to your thoughts
Thanks
