PRE-CHARGE PRESSURE ADJUSTMENT
The accumulator tank is pre-charged at 17.4 psi / 1,2 bar. lf your pump's electric pump cut-in pressure is
signi cantly different, you may adjust the tank pressure to better suit your particular installation. Air pres-
sure in accumulator tank should be 3 psi (0,2 bar) over water pump cut-in pressure.
To increase air pressure in tank, shut pump off, open a faucet to relieve system pressure, and adjust pre-
charged pressure using ordinary tire gauge and tire pump at valve in end of tank. Pressure should be
checked regularly. To check tank pressure turn off power to water pump, open a faucet to relieve pres-
sure. Check tank pressure, adjust if necessary. Close faucet and turn on power to pump.
