Installation Requirements
1. Install a minimum of 1" above flood level of fixture if factory
deck mounted or a minimum of 6" if general plumbing
application.
2. Install bonnet side up and allow for accessibility for testing/
service. Do not install in concealed locations or areas where
water leakage can cause damage due to normal wear of the
internal parts.
3. Do not undersize supply or oversize the valve in relation
to demand.
4. Do not install where backpressure can occur.
5. Protect assembly from freezing.
Note: Use "L" suffix for left-hand outlet.
6. The installation of a strainer ahead of the backflow preventer
is recommended to prevent fouling of the check assembly
and resultant spillage from the valve during start up and
repressuring.
