Question by: Jerry B on Feb 19, 2026, 7:26 AM
So, I gotta pre-charge this accumulator... what's the right way to hook this thing up and get it done without messin' anything up?
Answer by: Customer Support on Feb 20, 2026, 12:29 PM
Installation involves removing the gas valve guard and valve cap, then filling the accumulator about 10% full with system fluid for a cushion. After that, you can install the gas charging assembly on the gas valve stem and start pre-charging slowly with dry nitrogen gas, using a gas regulator.
