Why Choose an Optima Plus Retrofit
- Hands-free hygiene with infrared sensing and a manual True Mechanical Override (TMO) button for service or courtesy flushes
- Fast install on most exposed Sloan manual valves; use adapter kits where specified for special bodies
- Low maintenance with a factory 72-hour sentinel flush, low-battery LED, and typical battery life of about 3 years at 4,000 cycles/month. Powered by four C-cell alkaline batteries
- ADA-friendly activation with automatic range adjustment to accommodate typical approach distances. Sensor range is about 22–42 inches
- Operates within standard flushometer pressure ranges of 15–80 psi flowing, matched to your fixture’s requirements

Notes
- Side-mount operators do not include the valve body; they retrofit exposed Sloan manual diaphragm valves
- Dual-flush logic automatically delivers a reduced flush on short uses to save water (commonly paired as 1.6/1.1 gpf)
Compatibility Checklist
- Designed for exposed Sloan diaphragm bodies (Royal, Sloan, Regal, Crown). Mounts at the handle location and works on both left- and right-hand sides
- GEM-2 bodies and some third-party valves may require an adapter or a specific gasket
- Always confirm the fixture’s gallon-per-flush (GPF) rating. Select the correct diaphragm/regulator in the valve body, as the retrofit itself does not adjust flush volume
Pro Tips from the ProDryers Team
- Plan batteries and access. C-cells are housed in a pull-out tray; keep spares on hand for high-traffic restrooms and swap proactively when the LED indicates low battery
- Avoid reflective false triggers. Keep the lens clear of mirrors and shiny surfaces directly facing the sensor
- Closet vs urinal setup. Single-flush units can be toggled between closet and urinal modes during setup; dual-flush models are for closets only
- Don’t “open the stop” to chase performance. Always match the valve’s diaphragm/regulator to the fixture’s GPF, confirm pressure, and test for a clean flush
Frequently Asked Questions
What’s in the box?
The kit includes the side-mount sensor operator, sleeve assembly, collar wrench, hex tools, and a battery tray with four C-cell batteries factory installed.
Will it work on both left- and right-hand valves?
Yes. The housing mounts over the handle location on either side of the valve.
Do I need to replace my whole flushometer?
No. These retrofits convert compatible exposed manual valves to sensor activation without replacing the valve body.
How does the dual-flush save water?
It uses presence time to decide between a reduced or full flush, and also provides dedicated buttons for user-selected reduced/full flush when needed.
What’s the operating pressure?
Standard flushometer range of 15–80 psi flowing. Always confirm your fixture’s requirements on site.
