7. Open the faucet/tap and hot and cold water riser shutoff valves to purge
any air entrained in the valve or hoses and to insure there are no leaks at
any connections.
8. Remove the locking screw from the battery compartment cover on the
valve. Insert the batteries in their proper orientation into the compartment
on the valve. Be sure to match the positive (+) and negative (-) ends of the
batteries with the corresponding polarity symbols on the bottom of the
housing. Installing one battery in reverse will result in improper system
operation. Return the locking screw to its proper position when the
batteries have been installed.
CAUTION:
Short circuit hazard. Improper battery installation may
cause personal injury or property damage due to short
circuit or battery leakage.
This installation method applies to most situations where faucets/taps are
connected to hot and cold water supply lines with braided flexible hose/shut-off
valve arrangements. If the under-sink arrangement is different, for example the
risers are hard copper or plastic, then other parts not listed here may be
required for the installation.
