CAUTION:
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the
appliance.
For controllers not provided with supply cord, the xed installation must
include a disconnecting device for all three poles suitable for overvoltage
category III protection.
WARNING:
The LXME2 controller must be properly surge protected and grounded. Doing
so can help prevent damage to the controller and irrigation system and also
signicantly reduce troubleshooting, repair time and expense. Failure to do so
could result in failure of your controller and voiding the warranty.
Electric shock can cause severe injury or death. Make sure power supply is
turned OFF before connecting power wires.
All electrical connections and wiring runs must be made according to local
building codes.
The current date and time on the controller is retained by a long-life lithium
battery, which must be disposed of in accordance with local regulations.
This controller uses a non-replaceable lithium battery. Lithium batteries
are hazardous and can cause severe or fatal injuries in 2 hours or less if it is
swallowed or placed inside any part of the body. Medical attention should be
sought immediately if this is suspected. Keep batteries away from children
