How the YILIN Electronic Water Timer works.
Your electronic water timer will water your garden and
hanging baskets completely automatically according to the program you choose. You can set the timer to
water your garden early in the morning or late at night when water evaporates the least. It will continue to
water whilst you are on holiday. It provides two flexible methods to control irrigation:
1. Manual: press Man/Auto button to switch between: On - Off – Auto.
2. Automatic: Can water up to 8 times per day. Choose quickly from 15 different day combinations to
control which days of the week the timer operates.
TIMER INSTALLATION:
1. Unscrew and remove waterproof cover. Slowly slide out the battery box from its compartment in the face
of the timer. Install two new 1.5V alkaline batteries (size AAA). Replace battery box.
2. Hold the unit steady. Loosen the LARGE LOCKING COLLAR RING located in the top of the timer until
the inner FAUCET COLLAR is loose. Screw the FAUCET COLLAR onto the faucet/tap until it is hand
tight, and then hand tighten the LARGE LOCKING COLLAR RING. Turn on the faucet/tap to open the
flow of water. (DO NOT USE WRENCHES OR PLIERS TO TIGHTEN THE COLLARS.)
