A Raindrip model R672CT water timer allows automatic watering of the lawn or garden when homeowners are at work, asleep or away from the home. A water timer screws onto the hose spigot and into a garden hose on the opposite end. The spigot is in the "on" position to allow the timer to work. When the timer reaches the preset frequency, the internal valve opens and allows water to flow for the duration of the setting on the timer. The valve closes after the run time is reached to shut off the water flow. Water timers save time and water lawns efficiently without worry or wasting water.
Grasp the waterproof cover and turn it counterclockwise to unscrew it. Lift the cover straight up and set it aside. Set the controls at the time you want the first watering session to occur.
Turn the frequency knob clockwise to a setting from one hour to 72 hours or to a week. An hourly setting will repeat the water process each amount of hours indicated. For example, setting the hourly frequency at 12 will enact watering at 5 a.m. and 5 p.m. each day. The “Week” setting will water the lawn once a week.
Turn the run time knob clockwise for the duration of watering in minutes. Turn the knob to 30 for a 30-minute watering session for each frequency set.
Place the waterproof cover on top of the timer, and turn it clockwise to tighten it.
