Failure to respect the above equation may lead to malfunctions of the system or to premature breakage of the diaphragm inside
the expansion vessel.
Considering the expansion vessel capacity of only 1 litres, any operation to check the air pressure must be performed by connecting
the pressure gauge very rapidly: on small volumes the loss of even a limited quantity of air can cause an appreciable drop in
pressure. The quality of the expansion vessel ensures the maintenance of the set air pressure value, proceed to check it only at
calibration or if you are sure of a malfunction.
Any operation to check and/or reset the air pressure must be performed with the delivery system not under pressure: disconnect
the pump from the power supply and open the utility nearest to the pump, keeping it open until it no longer gives any water.
The special structure of the expansion vessel ensures its quantity and duration over time, especially of the diaphragm which is
typically the component subject to wear for items of this type. However, in the case of breakage, the entire expansion vessel must
be replaced and exclusively by authorised personnel.

2. INSTALLATION
The system is designed for indoor use: do not install the system outdoors and/or directly exposed to atmospheric agents.
The system is designed to be able to work in environments where the temperature remains between 1°C and 50°C (on condition
that the electric power supply is ensured: see par. 5.6.8 “anti-freeze function”). Esybox mini operates correctly with a difference
between ambient and liquid temperatures of no more than 30°C (with the ambient temperature higher than the liquid
temperature). Besides this temperature difference, the humidity limit must not exceed 50%, otherwise there is a risk of
condensation forming, which can cause irreparable damage to the electronic board.
