Water System Accumulator
Due to the operational requirements of the accumulator design, the high pressure internal gas pre–charge can bleed out during
periods of inactivity. Storing the Hydroject for extended periods of time (3 months or longer) and/or seasonal temperature
variances can affect the accumulators ability to retain a sufficient pre–charge and seasonal servicing (recharge) may be
required.
If one of the accumulator charge indicator lamps illuminates, contact your authorized Toro Distributor for accumulator
maintenance services.
