Atlantic CORSUN 1 Installation, Betrieb Und Wartung Seite 19

Recommendations:In very hard-water regions (Th>20°F), the use of a softener will not
invalidate the warranty as long as the softener is set up in accordance with standard practice
and is checked and maintained regularly. The water hardness must remain above 10°f.
5.1. Hydraulic safety
All installations must include hydraulic protection against:
1. Excess pressure in the distribution network,
2. Excess pressure due to rises in temperature (expansion during heating),
3. Excess pressure due to the failure of a thermostat or a contactor relay.
Drainage due to excess pressure must not be impeded. This means that the drain tube must
have a continuous and suffi cient slope and its diameter must be suited to the network.
Regardless of how the system is installed, it must have a cold water tap upstream of the
safety unit.
5.2. Hydraulic safety dimensions
The safety unit must comply with the standard. It must be positioned directly on the cold
water inlet.
The scale of the hydraulic safety provision depends on the capacity of the device.

Important:
• If an array of several devices is installed, a valve assembly must be fi tted to each tank and
a non-return fl ap on the overall supply pipe.
• If the pressure of the distribution network exceeds 5 bar, a pressure reducer must be fi tted
to the overall supply pipe.
• If metal piping is used, use a cast-iron sleeve or a dielectric pipe joint (brass connectors
are prohibited).
5.3. Hydraulic safety installation
5.3.1. Safety units:
Safety units are always installed on the cold water inlet to the tank. When installing the unit,
respect the fl ow direction indicated by arrows on the body of the security unit.
