INSTALLER SAFETY INFORMATION
WARNING
• An experienced, trained installer shall 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 death or serious personal injury and property damage.
1. Read and understand all instructions and refer to the trim
diagrams before installing, maintaining, or testing a Victaulic
Series 751 FireLock
™
European Alarm Check Valve Station. For
proper operation and approval, the alarm valve and accessories
shall be installed in accordance with the specific trim diagrams
included with the shipment.
2. Use only recommended accessories. Accessories and equipment
that are not approved for use with this alarm valve may cause
improper system operation and property damage.
3. Wear safety glasses, hardhat, foot protection, and hearing
protection. Wear hearing protection if you are exposed to long
periods of noisy jobsite operations.
4. Prevent back injury. Valve assemblies require more than one
person (or mechanical lifting equipment) to position and install the
assembly. Always practice proper lifting techniques.
5. Keep work areas clean. Keep the work area clean and well lit, and
allow enough space to accommodate proper installation of the
valve, trim, and accessories.
6. Avoid pinch points. Due to the weight of the valve body, use
caution around pinch points and spring-loaded components
(i.e. clapper assembly) in order to prevent bodily injury.
