– The manual’s filter restriction gauge is accurate, but the internal bypass valve can stick partially open without triggering the maintenance light. Symptom: normal temp but higher than usual current draw. Always manually inspect the filter housing.
Diagnostic flow charts for power issues, pressure fluctuations, and helium leaks. Safety Devices:
Go through the pre-operational checklist on page 1 of the manual. Verify:
Before operation, ensure the pressure gauge reads at least 1.60 MPa (232 psig). If it is lower, a helium refill is required.
