Setup and Installation
- Battery Installation: The AquaTimer requires two (2) AA batteries (not included). Open the battery compartment, insert the batteries according to the polarity indicators, and securely close the compartment. The unit will retain programming through battery changes.
- Attaching to Faucet: Connect the timer's metal coupling to your outdoor faucet. Ensure a tight, leak-free connection using the rubberized grip.
- Connecting Hose: Attach your garden hose to the outlet at the bottom of the timer.
- Initial Time Setting: Upon first power-up or after battery replacement, the display will prompt you to set the current time. Use the control buttons (likely indicated by '+' and '-' on the device) to adjust the hour and minute, then confirm.
Operating Instructions
The Melnor 3015 AquaTimer offers flexible programming for various watering needs.
Programming Automatic Watering Cycles
- Set Current Time: Navigate to the "TIME" setting on the display. Adjust to the current time using the control buttons.
- Set Start Water Time: Go to "START WATER". This sets the time your watering cycle will begin. The timer supports up to 6 watering times per day.
- Set Water Duration: Select "WATER FOR". Specify how long you want the water to run for each cycle (e.g., 120 MIN).
- Set Watering Frequency: Choose "WATER EVERY". This determines how often the watering cycle repeats (e.g., 12 HRS, or daily, every other day, etc.).
- Activate Program: Ensure the "PROGRAM" setting is set to "ON" or "AUTO" to enable the scheduled watering.
Manual Operation
To use the timer like a standard faucet for immediate watering, navigate to the "MANUAL" setting. Activate manual mode, and the water will flow until you manually turn it off or a pre-set manual duration expires.
Rain Delay Feature
The "RAIN DELAY" function allows you to pause your watering schedule for a specified period (e.g., 24, 48, or 72 hours) in anticipation of or during rainfall, conserving water. Activate this feature from the display and select the desired delay duration.
Maintenance
- Battery Replacement: When the "BATTERY" indicator shows "LOW" or "REPLACE", replace both AA batteries promptly to ensure continuous operation and prevent loss of programming.
- Cleaning: Periodically inspect the screen and buttons for dirt or debris. Wipe clean with a soft, damp cloth. Avoid abrasive cleaners.
- Winterization: Before freezing temperatures, disconnect the timer from the faucet and hose. Drain any remaining water and store the unit indoors in a dry, protected area to prevent damage from freezing.
