Before any work#

Check lists#

Daily, or each shift#

  • No leaks at the front panel fittings and the tubing.
  • Vent and drain lines intact and not blocked.
  • Outlet dew point and operating pressure in the normal range. No active alarms.

Monthly#

  • Rear fans running and air openings free of dust.
  • Dew point trend. A slow rise over weeks is a reason to contact HydroXpand.
  • Drain events. A clear increase points to more water coming from upstream.

Yearly#

  • Leak check of all connections at operating pressure.
  • Check the dew point sensor or analyser against a reference, as its maker recommends.
  • Check the power cord, the earth connection and the network cable.
