Checking the Accumulators’ Precharge Pressures
Check pressure at least once a month; more often as required by operating
conditions. An accumulators’ correct precharge pressure is written on its label.
See the Series 111 Accumulator Product Information manual (part number
011553304) for the complete details on checking the precharge intervals and
servicing the accumulators. Record both the pressures and the room temperature
in a logbook. Use these readings as a basis for increasing or decreasing the
interval between pressure checks. Generally, recharging is required when there is
a change of ±1.4 MPa (200 psi) in the pressure line accumulator or ±50% in the
return line accumulator.
