Flushing lines on a mini split - R410a to R22
Hi all,
In a previous post I was experimenting with propane in a R410 mini split which had lost its gas due to a pipe fracture. To cut a long story short, it was not the most efficient and because its hard (and expensive!) to buy R410 in Australia I have gone and bought an R22 unit off eBay. To make sure any old oil and crud is not left in the pipes it is best practice to flush the lines.... There are commercial flush fluids available but in the past I have used mineral spirits (Shellite) in automotive A/C to flush system components with no problems. Question: does R22 use mineral oil like old car R12 sytems? Not sure the date of manufacture, possibly 4-5 years old..but never installed. Thanks, James. |
