INSTALLER SAFETY INSTRUCTIONS
WARNING
• An experienced, trained installer must install this product in accordance with all instructions. These
i nstructions contain important information.
• Depressurize and drain the piping system before attempting to install, remove, adjust, or maintain any
Victaulic piping products.
Failure to follow these instructions can cause product failure, resulting in serious personal injury and/or property
damage.
GENERAL
1. Read and understand all instructions and refer to the trim
diagrams before proceeding with the installation, maintenance,
and testing of this Victaulic Series 751 FireLock European Alarm
Check Valve Station.
2. Inspect the shipment. Make sure all components are included in
the shipment and that all necessary tools are available for installa-
tion.
3. Use only recommended accessories. Accessories and equipment
that are not approved for use with this alarm check valve may
cause improper system operation.
4. Wear safety glasses, hardhat, foot protection, and hearing pro-
tection. Wear hearing protection if you are exposed to long periods
of noisy job-site operations.
5. Prevent back injury. Larger and pre-trimmed valves are heavy and
require more than one person or mechanical lifting equipment to
position and install the assembly. Always practice proper lifting
techniques.
6. Avoid using electrically powered tools in dangerous environ-
ments. When using electrically powered tools for installation, make
sure the area is moisture-free. Keep the work area well lit, and
allow enough space to accommodate proper installation of the
valve, trim, and accessories.
7. Watch for pinch points. Do not place fingers under the valve
body where they could be pinched by the weight of the valve. Use
caution around spring-loaded components (i.e. clapper assembly).
8. Keep work areas clean. Cluttered areas, benches, and slippery
floors can create hazardous working conditions.
9. PROTECT THE SYSTEM FROM FREEZING CONDITIONS. THE
VALVE AND SUPPLY PIPING MUST BE PROTECTED FROM
FREEZING TEMPERATURES AND MECHANICAL DAMAGE.
MAINTENANCE AND TESTING
1. Notify the authority having jurisdiction. Always notify the author-
ity having jurisdiction before performing any maintenance that
eliminates the fire protection provided by the system.
2. Follow national requirements and/or requirements of the local
authority having jurisdiction for system testing and inspection
schedules. The building owner or their representative is respon-
sible for inspecting the system in accordance with current national
requirements or in accordance with the requirements of the local
authority having jurisdiction (whichever is more stringent).
3. Depressurize and drain the system completely before performing
any maintenance. Water under pressure can cause the cover plate
to blow off during removal if the system is not depressurized and
drained completely.
4. Protect the valve from freezing temperatures, foreign matter,
and corrosive atmospheres. Any condition that might degrade the
system or affect system performance must be avoided.
