Descaling Heater Tank Before Filter Activation
HBA HBA 12 & 14
Descaling Heater Tank Before Filter Activation
This procedure ensures that the internal heating components and hot water delivery mechanisms are completely free of mineral buildup before any new water treatment system is engaged.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Descaling solution leak detected outside the tank: Stop immediately. Contain spill per solution safety data. Do not resume until leak source is identified and sealed.
- Tank shows signs of corrosion or metal degradation beyond scale: Stop descaling. Document findings with photos. Escalate to supervisor for tank replacement evaluation.
- If corrosion or significant degradation is observed on the tank structure, immediately stop and contact a qualified technician.
- If the descaling process fails to remove scale, do not proceed; contact a qualified technician for advanced chemical treatment or component replacement.
