  • Toshiba ESTIA A09-01P, Quick Reference Guide - Page 11 Pump operation / configuration Change Pump speed, so that water flow is always greater than the minimum flow rate. If water flow is lower than the minimum rate during operation, the unit detects error. Water charging Charge water until the pressure gauge shows 0.2 MPa (2 bar). Hydraulic pressure may drop when the trial run begins. In that case, add water. Air may enter if the charged hydraulic pressure is low. Loosen the purge valve cap by two turns to release air. Loosen the cap of the pressure relief valve to release air. Water may come out of the pressure relief valve. Rele
