The RBCMVA battery operated timer is factory assembled to fit 3/4" Champion and Orbit manual brass valves. Included in the package, you will find a 1" adapter and seat washer used to fit 1” Champion and Orbit manual brass valves, 3⁄4" and 1" Rain bird and 3⁄4" and 1" Orbit plastic valves. The RBCMVA can covert most manual brass or plastic anti-siphon valves to automatic operation.
NOTE: Please select proper adaptor.
Seven buttons with the center four buttons (left, right, up, and down arrows) are used to select or modify a program parameter. A large button accepts the parameter change and moves or skips to the next step or icon. The upper right button manually powers the timer on or off while the upper left button is used to stop irrigation.
Recommendations: Wrap all fittings with Teflon tape. Do not use pipe cement on the valve as it will damage the valve thread and void the warranty.
