SENSOR MODULE COMPONENT PARTS

ABOUT PRODUCT

• Sloan introduced its Optima Plus® battery powered sensor flushometer in 1992, revolutionizing the flushing of water closets and urinals. In both new construction and retrofit applications, the use of the Optima Plus has become the standard method for many facilities to improve restroom hygiene and ensure handicap accessibility compliance.
• In May, 2003 Sloan introduced the G2 Optima Plus®.
• The G2 Optima Plus® builds on the success of the original product and offers many technological advancements to further improve on performance and reliability expected of sensor activated plumbing. In addition to a new aesthetic design, the G2 Optima Plus® features a new state-of-the-art electronic and optical package and a solenoid operator. The G2 Optima Plus replaces the original Optima Plus® product, which was phased out of production in mid-2003.
• The Sloan G2 Optima Plus® automatic battery powered flushometer relies on an infrared sensor to detect a user and activate a flushing cycle. No physical contact with the flushometer surface is necessary, assuring sanitary protection. G2 Optima Plus® flushometers are ADA compliant devices.
• The flushometer is triggered by means of an active infrared sensor. The Optima Plus® sensor emits a continuous invisible light beam. When a user enters the beam’s effective range, the beam is reflected into the Optima Plus scanner window. The user is now detected. After the user moves out of the effective range of the sensor, a signal is sent to the flushometer solenoid and, after appropriate arming and/or flush delays, the flush cycle is initiated.

BATTERY REPLACEMENT

• When G2 Optima Plus® has approximately 4,000 flushes left, the same red light that appears at start-up will flash four (4) times quickly whenever an object is detected. When this occurs, we recommend changing the batteries as follows:

• When required, replace batteries with four (4) type AA batteries.
  Note: Water does not have to be turned off to replace batteries.

• Loosen the two (2) screws on top of unit. Remove the complete cover assembly. Lift the sensor module from its plate. Unplug the electrical connector from battery compartment cover. Loosen the retaining screw on battery compartment cover and remove battery compartment cover. Install four (4) alkaline type AA batteries exactly as illustrated at right. Install battery compartment cover and secure with retaining screw. Make certain that battery compartment cover is fully compressed against gasket to provide a seal; Do not overtighten. Plug the electrical connector into the battery compartment cover. Reinstall the sensor module onto the plate.

• Reinstall the complete cover assembly onto the plate. Tighten the two (2) screws on top of the unit.

RANGE ADJUSTMENT (ADJUST ONLY IF NECESSARY)

• The Optima Plus has a factory set sensing range:

  • Water Closet Models – 22” to 42” (559 mm to 1067 mm)
  • Urinal Models – 15” to 30” (381 mm to 762 mm)

• The Factory setting should be satisfactory for most installations.

• If the range is too short (i.e., not picking up users) or too long (i.e., picking up opposite wall or stall door) the range can be adjusted.
  Note: Water does not have to be turned off to adjust range.

• Make sure to remove all the non-permanent targets in sensor view area. Push manual override button for 25 seconds. the Red LED in the G2 sensor starts slow blinking. Release the button during the LED blinking. The G2 will enter into distance setting mode. The setting mode will run for one (1) minute.
  IMPORTANT !!!
  WHEN ADJUSTING RANGE FOR URINAL SENSOR, MAKE SURE TO SETUP A PROPER TARGET IN FRONT OF URINAL SENSOR.

TROUBLESHOOTING AND MAINTAINING THE SLOAN G2 OPTIMA PLUS® FLUSHOMETER

IMPORTANT:

• This product contains mechanical and/or electrical components that are subject to normal wear. These components should be checked on a regular basis and replaced as needed to maintain the valve’s performance.
• Never open Control Stop to where the flow from the valve exceeds the flow capability of the fixture. In the event of a valve failure, the fixture must be able to accommodate a continuous flow from the valve.

ATTENTION INSTALLERS:

• With the exception of the control stop inlet,
• DO NOT USE pipe sealant or plumbing grease on any valve component or coupling! To protect the chrome or special finish of Sloan flushometers,
• DO NOT USE toothed tools to install or service these valves. Use our A-50 Super-Wrench™ or other smooth-jawed wrench to secure couplings.
• Regulations for low consumption fixtures (1.6 gpf/6.0 Lpf closets and 1.0 gpf/3.8 Lpf urinals) prohibit use of higher flush volumes.

ELECTRONIC MODULE ASSEMBLY CHART

• The electronic and optical improvements of the G2 Optima Plus® have been incorporated into the electronic modules for use with older Optima Plus products.
• Optima Plus® modules can be identified by color.
• Old style modules are black and have a wire that runs along the side of the unit.
• G2 modules are blue and have a wire only on the back of the unit.
• There are now only two electronic module assembly variations for use with older Optima Plus valves:
  • EBV-146-A-U Urinal
  • EBV-146-A-C Water closet
• This chart cross references the part numbers and code numbers of our new electronic modules over from our old module numbers.
• The modules include the solenoid, inner cover and electronic module.
• These modules are for use with older Optima Plus and Regal Pro® Optima
• Plus® valves only.

BATTERY REPLACEMENT

• When Optima Plus has approximately 4,000 flushes left, the same red light that appears at start-up will flash four (4) times quickly whenever an object is detected. When this occurs, we recommend changing the batteries. On Optima Plus, shut off water and relieve pressure.
• Separate locking ring, cover and diaphragm from electronic sensor module.
• Loosen retaining screw on battery compartment door and remove battery compartment door. Install four (4) AA batteries exactly as illustrated. Install battery compartment door and secure with retaining screw. Make certain that battery compartment door is fully compressed against gasket to provide a seal; do not overtighten.

FLEX TUBE DIAPHRAGM ASSEMBLY

• In early 2003 Sloan introduced the flex tube diaphragm kit into the Optima Plus. This design completely replaced the old Optima Plus diaphragm kit that featured the metal shaft with the quad Ring. This change further improvedthe reliability of the Optima Plus as it replaced a wearable dynamic seal (the Quad Ring) with a non-moving static O-ring seal.
• The flex tube diaphragm kit also features Sloan’s exclusive dual-filter diaphragm. The dual-filter diaphragm helps to protect the valve from waterborne sediment that can cause the valve to stick open and run on. The  dual-filter diaphragm is also made from Sloan’s Permex® synthetic rubbermaterial for resistance against chloramines and other water treatment chemicals.
• The flex tube diaphragm can be used to replace all generations of Sloan Optima Plus® diaphragm kits. The same flex tube diaphragm kits are used in the G2 Optima Plus® valve.

TROUBLESHOOTING GUIDE

IMPORTANT:

• The OPTIMA PLUS® flushometer is engineered for quiet operation. Excessive water flow creates noise, while too little water flow may not satisfy the needs of the fixture. Proper adjustment is made when plumbing fixture is cleansed after each flush without splashing water out from the lip AND a quiet flushing cycle is achieved.
• Never open Control Stop to where the flow from the valve exceeds the flow capability of the fixture. In the event of a valve failure, the fixture must be able to accommodate a continuous flow from the valve.

ATTENTION INSTALLERS: With the exception of the control stop inlet, DO NOT USE pipe sealant or plumbing grease on any valve component or coupling! To protect the chrome or special finish of Sloan flushometers, DO NOT USE toothed tools to install or service these valves. Use our A-50 Super-Wrench™ or other smooth-jawed wrench to secure couplings. Regulations for low consumption fixtures (1.6 gpf/6.0 Lpf closets and 1.0 gpf/3.8 Lpf urinals) prohibit use of higher flush volumes.
