The authority having jurisdiction may
also require a high-pressure alarm.
2.
Set the air supervisory switches to activate at 0,3 Bar be-
low the minimum air pressure required.

HYDROSTATIC TESTING
The Victaulic Series 756 European Dry Valve is manufactured
and listed for a maximum working pressure of 16 Bar and is fac-
tory tested to 41 Bar. The station can be hydrostatically tested to
14 Bar and/or 3,5 Bar above the normal water supply pressure
(2-hour limited time period) for acceptance by the authority hav-
ing jurisdiction.
CAUTION
• Make sure foam spacers are removed before
attempting to install the valve.
Failure to follow this instruction could cause
improper valve operation, resulting in serious
personal injury and/or property damage.

• If air testing is required, DO NOT exceed 3,5
Bar air pressure.
Failure to follow this instruction could result in
serious personal injury, property damage, and/
or product damage.
