Question Answer
Why is my tap timer making a
funny noise and not opening?
☑ If you are running a low pressure
drip system, you need to install an
Air Release Valve (102646) at
the highest point of your system
and above your drippers
☑ This breaks the air in the drip line
and allows it to suck in air through
the air release valve, preventing
the drippers from blocking due
to dirt. This also allows for the
diaphragm to work properly
My tap timer is currently
watering, how can I stop it?
☑ To stop manual or automatic
watering press
Why has my tap timer stopped
all programmed watering?
☑ The battery could be flat. The
battery indicator has 5 levels. 4
levels of battery and 1 flashing
bar when the battery is flat
☑ The Tap Timer will not water when the
battery is in this mode. We advise to
change the battery when it is down
to 2 bars to ensure reliable watering
If I use my timer manually, will
I need to reset my timer?
☑ No. If you press the ON/MANUAL
button, your timer will run for the
duration set then turn off. This
will not affect the program
Air
Release
Valve
102646
It can be used to release air from the drip line
when the system is turned on. Eliminating
any air pockets. It also allows air to freely
enter the system when it is shut down. This
ensures a vacuum does not draw debris into
the drip line via the dripper outlets.
