4.DESCRIPTION
Hidrotank-H1 is a device that enables pumps, with a minimum prevalence of 2
bar, to start and stop automatically, with regard to a drop in pressure (opening
of the taps) and to the stopping of the flow through the system (closing of the
taps) respectively. Should the water supply be interrupted for any reason,
Hidrotank-H1 performs the important function of stopping the pump, thus
protecting it from harmful dry running. It is also able to restart automatically,
by means of an inbuilt timer, to check for the eventual presence of water (this
function is only available for versions with automatic reset function). The
integrated 0.4 Lt expansion tank reduces unwanted pressure surges as well
as "pump cycling" which may arise due to the presence of small leaks within
the system. The inbuilt pressure gauge makes it easier to control the pressure
within the system; moreover any leaks in the system itself are easily identified.
Where applicable, the secondary pressure gauge installed on the back of the
unit, facilitates the routine checking of the pre-charge value (fig. 03).
It is strongly recommended that the water is free of any sediment. If
in doubt, it is necessary to install an appropriate sediment filter on
the inlet side.
The device must not be installed inside wells or sealed enclosures,
where heavy condensation is likely to form.
Both Hidrotank-H1 and the pump itself must be protected against
freezing during cold weather spells.
