Useful Tips
BATTERY LIFE
- Only use fresh long lasting alkaline batteries
- Do not use rechargeable batteries
- Turn off the unit when not in use
- Remove the batteries before storage
- Moisture sensor uses more energy
- Frequently watering schedules can cause the batteries to drain faster
CLEANING YOUR TIMER
Your timer should be cleaned periodically. From time to time, you may get
sediment or dirt build-up in your timer. Follow the information below.
1) Turn of your water faucet. Remove the timer from the faucet connection
and your hose connections. Look at the filter washer at the faucet
connection input. Check that the filter washer is clear of any built-up
sediment.
2) If the filter is dirty, remove the filter washer from the timer. Clean out
the filter washer by placing it under running water.

SEASONAL STORAGE
3) Turn the timer upside down and activate the MANUAL mode. This will
open up the valves and allow you to run water into the output connectors.
By doing this, you can see if there are any clogs in the water flow. Once
you see the water flow is correct, deactivate the MANUAL mode.
Cold or freezing temperatures can damage to the timer if still connected
to the faucet. At the first forecast of frost, it is best to remove the timer
from the faucet and place the timer indoors. (Cold water, if left in the timer,
will damage the timer from the ice formed).
- Remove the batteries when the timer is placed in storage
- Recycle used batteries, do not dispose in the garbage
