OPERATING INSTRUCTIONS

1. Adding More Water To Toilet Bowl

Pull up the flush handle (3300 model) or push "Add Water" switch (3400 model) until the desired water level is attained. To prevent overflowing the toilet, a timer inside the control module limits the amount of water that can be added.

2. Flushing The Toilet

Push the flush handle down (3300 model) or push "Flush" switch (3400 model) for a moment, then release it. Holding the handle or switch down will not prolong the flush cycle nor start a new flush cycle. The handle or switch must be allowed to return to the neutral position before another flush can occur.

3. Mode Switch

The Mode switch is located on the right side of the control module. It lets you switch between three function settings:

NORMAL

Use this setting for flushing the toilet.

SERVICE

Use this position for cleaning the toilet bowl and flush ball seal. The flush ball will open automatically and re- main open in this position. Lifting up the flush handle or pushing the "Add Water" switch provides water to the bowl.

MANUAL OVERRIDE

Use this position to flush the toilet manually in the event of power or battery failure. This switch disconnects the electronic brake in the flush valve motor, and allows manual flushing via the override access hole in the side of the vitreous china base.

Note: The control module allows 15 seconds of water flow for cleaning. If more water is required, return the switch to the NORMAL position, then back to the SERVICE position.

A safety circuit in the control module monitors flush ball operation. If foreign objects or low voltage prevent the flush ball from closing, this circuit prevents personal injury or damage to the flush valve motor. If this condi- tion occurs, reset the control module by placing the Mode switch into the SERVICE position temporarily, then returning it to the NORMAL position.
