Cautions
Do Not Use products containing petroleum distillates or formaldehyde on any rubber parts.
Use only Silicone Lubricants!
Do Not Use any “Loctite” brand adhesive on any plastic or Delrin components as fumeswill cause damage to plastic parts. System vacuum breaker is not intended to be pressurized longer than a normal flushing cycle.
System vacuum breaker is not intended to be
pressurized longer than a normal flush cycle.
Flush 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.

Model LF-220 Downward Discharge (All dimensions +/- 0.5")
Installation
Refer to Rough-In Dimensions
Note: This toilet is a drop-thru unit. No horizontal waste line runs may be utilized. Contact the factory for specific application data.
Mounting Toilet
Turn toilet upside-down and place enclosed Wax Ring (P/N 27208), onto the bottom of mouting flange of the toilet hopper. Carefully turn toilet right-side up and place over the center of a standard floor discharge flange. Press toilet down firmly and evenly to form a seal between the wax ring and the floor flange. Mount the toilet to the floor with the four Closet Screws and install Bolt Caps over the closet screws (both provided).
Electrical Connection
See Rough-In Dimensions and Exploded View. Connect 12 volt DC power source to the insulated
.25” spade connector near the Timer and Thermal Circuit Breaker: red wire to positive (+), black wire to negative (-).
Water Connection
See Rough-In Dimensions.
Connect fresh water from an angle stop to the 1/2” threaded water supply connection on the side of the bowl installing Filter Screen (P/N 29146). Take care not to cross the threads. Incoming water pressure must be between 20-50 PSI, with a minimum flow rate of 2.5 GPM at the toilet.
Ideal water pressure is 35 PSI at the toilet. Be sure water lines are free of debris before connecting water supply to toilet. Water supply to the toilet is to be 1/2” OD plumbed directly to the toilet. Do not install filter(s) in the toilet water supply line.
Water Level
The normal water level is factory pre- set to the top of the Flapper.
Water Level Adjustment
Locate the timer on the bracker under the china lid. Turn Timer adjustment knob clockwise to increase water level, and counterclockwise to decrease. Do not turn past stops.
Seat Installation
Place the seat over the bowl opening, so that the mounting hinges on the seat align with the two holes in the bowl just behind the bowl opening. Insert the two seat mounting screws provided with the seat into the hinges’ holes and mounting holes in the bowl, from the top. Install washers and mounting nuts provided with the seat, from under- neath, and tighten firmly. Install screw head cover tabs or other hardware provided with the seat, per seat manufacturer’s instructions.
Maintenance
If the toilet is to be out of service for a period of time, spray 100% silicone on the flapper seal when the flapper is open to prevent if from becoming dry.
Winterizing
Shut OFF water to toilet. Flush toilet three times or until water no longer flows into the bowl. Unhook water supply at angle stop. Empty water in line into receptacle.
