Chapter 4 Maintenance

4.1 Regular maintenance

1) Clean the bath interior and exterior of the equipment periodically to keep the equipment
clean;
2) Check for hydraulic tightness and fastening of the connections for flexible hose, fitting and
coupling;
3) If the immersion heating circulator is removable for convenience of operation, check the
fixing device and bridge to make sure the equipment is secured in place and safe;
4) Check fixing screws periodically, and if any loose, fix it.
Remove the plug from power line before cleaning. Use soft dry tissue to clean the bath interior
and avoid any splashing or washing!
If any water or other conductive material fall into the equipment containing electric and/or
electronic parts and components, disconnect the power immediately. Power on only after water
or foreign material is completely evaporated or removed.

4.2 Regular check of the STB

Regular check of the STB is required for safe operation. Intervals of six months for normal use, or
the first time powering up after repairing or standstill for long period, are recommended for
regular check of the functionality. Check the STB as follows:
1) Fill the tank with water to level just over the highest point of the heating coil;
2) Set the temperature at 10°C above the ambient and/or the liquid, so that it keeps heating,
LED is continuously on;
3) Initiate the temperature control as for normal use, i.e. the pump is circulating and heating
is in full capacity;
4) Drain the bath so that the heater and the STB are exposed to the air completely. Make
sure no liquid spraying out from the circulating return, dripping from the drain device on
the bench or floor;
5) The liquid evaporates immediately from hot surface of the heater. Keep running dry for a
couple of seconds until the Stb warning is displayed. Caution, Never run dry for more than
90 s!
