Flushing Your Toilet
IMPORTANT!The ush for your toilet is unique. It is a two stage ush designed for superior performance while
using a small amount of water. It will seem as if your toilet is ushing twice. This is proper operation.
NOTE: When you receive your toilet, it is set to ush automatically. The toilet will ush automatically aer
each use. The toilet will determine the appropriate ush type (ush-eco or ush-full) automatically. Refer to the
“Seing - Auto Open, Auto Flush, Deodorizer ″ section for instructions on enabling or disabling the auto ush
feature.
NOTE: There are two ushing options. The [ush-eco] option uses 0.6 (2.3 l) gallons of water and is intended for
liquid removal. The [ush-full] option uses 1.28 (4.8 l) gallons of water and is intended for solid waste removal.
¨For liquid waste remove, select [ush-eco]. The ush takes approximately 30 seconds.
¨For solid waste removal, select [ush-full]. The ush takes approximately 45 seconds. There is a rst-stage
ush, the bowl is partially relled, and a second stage ush takes place.
