ATTENTION! NEVER SWITCH THE WATER HEATER ON WITHOUT FILLING WITH WATER:
For models fitted with an electrical resistance, this would automatically be deteriorated.
- The secondary circuit must be filled. Before switching on, open the hot water taps and
bleed the pipes until there is no air inside.
- Check the pipes and door seal under the cover are airtight. In the event of a leak, tighten
moderately. Check that the hydraulic safety and drainage devices are in good working order.
- Switch the unit on.
- After between 15 and 30 minutes, depending on the capacity of the unit, the water should
flow drop by drop from the drainage outlet. This normal phenomenon is the result of
the water expanding. Check the pipes and seal are airtight. When the water is heating,
and depending on the quality of the water, reinforced water heaters may emit a bubbling
sound; this noise is normal and does not mean that the unit is in any way damaged. The
thermostat is set to 65°C as standard.
- IMPORTANT: If a constant emission of steam or boiling water is observed via the drainage
valve or by the opening of a tap, cut the electric power supply to the water heater and
contact a professional.
