INSTALL THE TIMER TO WATER TAP

Open the battery compartment cover and follow the +/- marks to place 2 new 1.5 V 'AA' alkaline batteries.
Attach the water timer (already with a built-in filter) to an outdoor water tap.
An O-ring / adapter / PTFE tape can be used as a protection against water leakage.
Connect water pipes at the zone outlets with quick connectors if needed.

Important Notes:

Intended for outdoor use only.
Do not use tools on the timer. Hand tighten enough.
Do not use water lower than 3°C or higher than 45°C.

Tips:

The water inlet must be equipped with a filter to prevent impurities from blocking the valve, which may result in valve switch failure or water leakage. Please clean or replace the filter in time.
The working water pressure for the timer is 0.05-0.8 Mpa. The timer itself does not generate pressure and needs tap water pressure or water source with pressure to work well.
