Hey I got a question. I just received the new compressor, condenser, drier
It says my compressor is prefilled with 8oz of Pag 46. 8oz is max oil for my system will this disperse thru the system from the compressor?
What I would do is
- drain the oil from the compressor (the Sanden doc attached gives generic instructions for draining)
- measure the amount drained from the compressor
- assume 0.5oz will remain in the compressor after draining
- add the above two values, that's the total oil charge provided from the compressor (they're usually filled with the correct amount,
but sometimes they aren't...)
- add/remove any shortfall / excess to what you've drained...
-- e.g., if the system needs 8oz and you drained 7oz (and remember there's 0.5oz remaining in the compressor), then add 0.5oz to what you've drained
-- e.g., if the system needs 8oz and you drained 9oz from the compressor, pour-off 1.5oz (remember there's 0.5oz remaining in the compressor)
- place half of the oil you now have in the accumulator (3.75oz in this example, more or less, it's not critical)
- (re)place the rest of it in the compressor
That's how I do it.
Upon initiating operation, the circulating refrigerant will carry oil from the accumulator to the compressor, which aids lubrication.
Long-term, yes, even if you didn't follow the instructions above, all oil in the compressor would (eventually) find itself dispersed throughout the system.
Use clean measuring devices. Any debris/crap introduced into the oil will circulate in the system
forever.
Peruse the Sanden information attached, it's somewhat generic to all compressors and there may be instructions within that you may find interesting.
