This is an addon to the Luxaire Warranty thread. Bristol Comp Co also abides by the Rheem "max refrig in a system chart" for their entire residential line of comps.They vary from 6lbs of freon for a 62k comp and a 36k comp. But for a 42k they go upto 9lbs in the entire system. So use a CCH or don't use one ,thats your call. I really like being known for having comps that last and last and last.My longest surviving comp was a measly 30 years . so again ,you tell me!!!!!

An update, a Territory Manager for United Refrigeration said "off the top of my head it's about 9-10 lbs for Copeland". So again ,you tell me!

    One more little fact, Bristol uses a CCH in their entire commercial line of comps.

    What gas?

    Are these for current 410 units or for dry units?

    The Rheem chart is for r22 ,but I'm going to say I don't know if it applies to 410a, but now I'll have to go check that out.

    I saw this in the I/O for their dry unit. I guess they figure the units will be overcharged in order to work with the who-knows-what ancient evap. But guys that do dry units on old coils aren't real likely to worry about how long the dry unit will last.
