ADJUST HOT LIMIT STOP
SERVICE
nBy restricting HANDLE rotation and limiting the amount of hot water allowed to mix with the cold, the HOT LIMIT SAFETY
STOP (1) reduces risk of accidental scalding. To set the maximum hot water temperature of your faucet, all you need to
do is adjust the setting on the HOT LIMIT SAFETY STOP (1).
nUse a at blade screwdriver or your ngers to
pull up and rotate red HOT LIMIT SAFETY STOP (1).
Follow Step “A” or “B” to adjust min./max.
discharge temperature. “0” being the
hottest to “7” the coldest temperature
setting. Factory set at “0”.
nIf faucet drips, operate CARTRIDGE PIVOT (1) handle several
times from “off” to “on”. Do not apply excessive force.
nClogged CARTRIDGE (3) inlets may cause reduced ow in “full
on” hot or cold. To clean inlets, rst turn off water supply, then:
• Remove and CARTRIDGE (3). Clean inlets and MANIFOLD (4).
• Reassemble CARTRIDGE (3), alternately tightening SCREWS (2).
