Recommended installation space
For maintenance operations to take place, there must be:
- a clear space of at least 50 cm in front of the plastic cover to allow access to the lateral flange,
- direct access to the safety assembly,
- particular case of installation in a bathroom (NF C15 100).
Advice :
To prevent overconsumption of energy, it is recommended
that the heater be positioned as closely as possible to the
hot water usage points. (a distance of less than 8 metres is
recommended).
Water connection and preliminary operations
- Verify that the useful thermal power from the generator exceeds the power that the tank can absorb by more than 15%.
- Verify that the volumes and the pre-charge pressure of the secondary circuit expansion reservoir are suitable for the system.
- If the water in the circuit is excessively hard (TH > 25°F), install (upstream of the tank), a correctly adjusted water softener.
- If impurities are found in the water in the circuit, install a suitable filter, making sure that the circulators have sufficient flow and a sufficient
extractor and that they rotate regularly.
- Verify that the thermostat sensor is correctly positioned.
- Verify that the thermostat controls are functioning correctly, if using an optional electrics kit.
- Install a safety assembly that meets current national and EU standards, and which is suitable for the maximum working pressure
indicated on the product identification label.
