    Jackryan,
    A few things I think in no particular order.
    - check & drain oil in oil from all drain points, oil pot, column etc.
    - operation of level control, solenoids, float switches working & look ok, no moisture inside etc.
    - liquid pump pressure normal
    - liquid pump condition, seal, bearing monitor depending on type hermetic or open drive.
    - change over liquid pump if has standby.
    - gauges, pressure switch, valve condition.
    - relief valve condition on oil drain pot & vessel.
    - corrosion of pipe & fittings.
    - 6 monthly high level safety cut out check
    - 6 monthly relief outlet & pipe check for fouling/ deterioration.
    - relief calibration due date
    - vessel inspection due date
    - insulation condition
    - vessel leg condition
    - sight glass or bullseye clean.
    - excessive ice formation on/ around valves in case of emergency

    Probably other things, see if anyone can add.
