Safety Features During Operation:
The Regera water heater incorporates an Advanced 3-Level Safety Protection system to ensure safe operation:
- Thermal Cut-out: Automatically shuts off power if water temperature exceeds safe limits.
- Pressure Release Valve: The Multi-Functional Valve (MFV) releases excess pressure if it builds up inside the tank.
- Dry Heating Protection: Prevents the heating element from operating without water in the tank, protecting it from damage.
5. Maintenance
Regular maintenance ensures the longevity and efficient performance of your Crompton Regera water heater. Always disconnect power before performing any maintenance.
Routine Checks:
- External Cleaning: Wipe the exterior of the water heater with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Leak Inspection: Periodically check all water connections and the unit's body for any signs of leaks. Address any leaks immediately.
- MFV Operation: Once a year, manually operate the Multi-Functional Valve (MFV) by lifting the lever to ensure it is not clogged and functions correctly. Water will discharge, so ensure proper drainage.
Internal Maintenance (Recommended Annually by Professional):
- Draining the Tank: For long periods of non-use or for internal cleaning, the tank can be drained. Turn off power and water supply, then open the drain valve at the bottom of the unit.
- Descaling: Although the unit has an Advanced Anti-Scale Heating Element and a Glassline Coated Tank, mineral deposits can still accumulate over time, especially in hard water areas. A professional can inspect and descale the heating element and tank if necessary.
