SECOND STAGE<br />
LOW PRESSURE<br />
PRODUCT DESCRIPTION<br />
The Type 776 is a second-stage, low presure regulator<br />
The Type 738 is a second-stage low presure regulator suitable to<br />
be installed in double stage pressure regulated domestic installarion.<br />
Both <strong>regulators</strong> cannot be used as single stage <strong>regulators</strong>,<br />
but they always have to be installed after a 1st stage regulator.<br />
The type 738 reduces the pressure at the outlet from the 1st stage<br />
directly to the utilization pressure <strong>of</strong> the final appliances.<br />
See diagram schematic: D-13, D16 (page C07), D-23 (page C12)<br />
and D-26 (page C13) for installation system.<br />
SAFETY DEVICES<br />
Under-Pressure Shut Off (UPSO) Protection<br />
The Type 776 is provided with a third safety device, called UPSO,<br />
which will operate when the installation supply pressure is insufficient<br />
and, therefore, the regulator is unable to guarantee a correct<br />
operating pressure. After activation <strong>of</strong> UPSO devices and removal<br />
<strong>of</strong> any anomalies, it is necessary to reset the safety devices by<br />
hand in order to resume the regulator correct operation.<br />
GAS<br />

ACCESSORIES<br />
On request, it is possible to supply a mounting bracket for the correct<br />
position on every surface <strong>of</strong> the regulator and with a protection cover.<br />
