Safety group
The safety groups protect the water heaters when the internal pressure reaches 7 bar. This also allows the
opening and closing of the water supply to the water heater and the emptying of the water heater by
operating the valve cap. The safety group must be connected to the gutter by means of a drain pipe. The
drain pipe must be free of obstructions so that the excess water can drain off normally.
Electric connection
Where a booster resistor is required, a circuit breaker must be installed. This installation must be carried
out by a certified electrician.
Lightning protection
The load-bearing structure of the collectors must be earthed. If a lightning protection device is already
provided for the building, the metal piping of the solar system must be connected to this device with a
green/yellow conductor cable with a minimum cross-section of 6 mm² Cu (H07 V-U or R). If this is not the
case, an earth spike can also be used for earthing.
Decommissioning and dismantling
The system must be dismantled early in the morning to avoid the risk of burning. Be aware of the system
temperatures before starting dismantling. Cover the collectors the day before if possible, to prevent the
passage of solar radiation.
