(par. 5.5.1) in bar
So, by the manufacturer: Pair = 3.0 – 0.3 – 0.7 = 2.0 bar
If different values are set for the parameters SP and/or RP, regulate the valve of the ex
-
pansion vessel releasing or letting in air until the above equation is satisfied again (e.g.:
SP=2.0bar; RP=0.3bar; release air from the expansion vessel until a pressure of 1.0 bar
is reached on the valve).
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.
