3. Cycle Operation The Model LF 220 Microflush Toilet is an electrically operated drop through type toilet using approximately two quarts of water per flush Wastewater is flushed from the bowl through a Hopper and drops directly into a holding tank A Flapper valve at the bottom of the bowl holds fresh water in the bowl and seals out odors from the holding tank 1 When the flush lever is operated a motor driven cam begins to turn which opens the Flapper valve at the bottom of the bowl allowing the wastewater to flow down into a holding tank Simultaneously the water solenoid valve opens allowing fresh water to flow from the rim and rinse the bowl The cam continues to turn and the Flapper will close again after approxi mately 4 5 seconds 2 After the Flapper has closed fresh water continues to enter the bowl to a predetermined level until the Timer closes the solenoid valve An adjustment on the Timer allows adjustment of the water level in the bowl to compensate for water pressure fluctuations A vacuum breaker is provided as an anti siphon device Flush Cycle an i KOT YZ m Model LF 220 Downward Discharge All dimensions 0 5 Elongated 26 5 Round 24 5 ne 18 75 Me eee z Electrical 7 a Connection Finished Wall gt Pipe Thread oes t oa 1 i p pn i no E La O D Pipe Size tma ee bs cede i Er 233 z it to accomo
