The Sloan Optima® EAF-275 Faucet is an advanced, sensor-activated faucet designed for efficient and hygienic water delivery. This device is engineered to provide a touchless experience, promoting cleanliness and water conservation in various settings. Its core function revolves around an infrared sensor that detects user presence, automatically activating and deactivating water flow, thereby eliminating the need for physical contact with the faucet handles.
The EAF-275 Faucet operates primarily through its integrated sensor assembly, which is available in two versions: one without i.q.-cliq and another with i.q.-cliq functionality. When a user approaches the faucet, the sensor detects their presence, triggering the solenoid valve to open and allow water to flow. Once the user moves away, the sensor no longer detects presence, and the solenoid valve closes, stopping the water flow. This touchless operation is crucial for maintaining hygiene, especially in public or high-traffic environments, as it minimizes the spread of germs.
The faucet incorporates a cap and solar cell assembly, which likely contributes to its power management, potentially extending battery life or providing an alternative power source. Water is dispensed through an aerator spray head, with several options available to suit different flow rate requirements and preferences. These include a 0.5 gpm (1.9 Lpm) VR Aerator Spray Head (pre-03/2011), a 2.2 gpm (8.3 Lpm) Aerator Spray Head, a 2.2 gpm (8.3 Lpm) Laminar Flow Spray Head, and a 0.35 gpm (1.3 Lpm) Multi-Laminar Spray Head. The choice of aerator allows for customization based on water conservation goals or specific application needs.
For installations requiring manual temperature control, the faucet can be equipped with a mixer handle assembly and cartridge. This allows users to adjust the water temperature to their desired level, providing comfort and flexibility. The handle repair kit and handle cap are also available for maintenance of this component.
The water supply to the faucet is managed through flexible supply hoses, and a solenoid valve is the critical component that controls the on/off function of the water flow based on sensor input. Strainers (filters) are integrated into the system to prevent debris from entering and potentially clogging the faucet mechanism, ensuring consistent performance.
The faucet's design also considers installation flexibility, offering trim plates for both 4" center-set and 8" center-set sinks. For specific installation requirements, faucet extension kits are available in different lengths (6 3/4" and 2-1/4"). The 2-1/4" extension kit is particularly noted for raising the faucet outlet height to comply with California Office of Statewide Health Planning and Development regulations, highlighting its adaptability to various building codes and accessibility standards.
The primary usage feature of the EAF-275 Faucet is its touchless activation, which provides a hygienic and convenient user experience. Users simply place their hands within the sensor's detection range, and water flows automatically. This eliminates the need to touch potentially contaminated handles, making it ideal for restrooms, healthcare facilities, and food service areas.
The availability of different aerator types allows for tailored water delivery. For instance, a multi-laminar spray head might be preferred for a softer, splash-free flow, while a higher gpm aerator could be chosen for applications requiring faster water delivery. The optional mixer handle provides manual temperature adjustment, enhancing user comfort, especially in environments where water temperature preferences vary.
The faucet is designed for ease of installation, with components like the faucet mounting kit and various trim plates facilitating integration into different sink configurations. The extension kits further enhance its versatility, allowing for adjustments to faucet height to meet specific design or regulatory requirements.
Maintenance of the EAF-275 Faucet is designed to be straightforward, with clear instructions provided for common issues. A key maintenance feature is the battery replacement process, which is indicated by a red LED flashing when the faucet is in use or stops functioning. The battery replacement kit (CR-P2) is readily available, and the process involves loosening a screw, removing a cap, detaching the battery retainer tab, replacing the old battery with a new 6 Volt Type CR-P2 lithium battery, and then reinstalling the components. The system includes a visual cue (LED flash) during battery installation to confirm proper function.
Troubleshooting guidance is comprehensive, addressing issues such as the faucet not functioning, delivering water uncontrollably, failing to deliver water when the sensor is activated, delivering only a slow flow, not stopping water delivery, or having incorrect water temperature. These guides often point to simple solutions like checking for adhesive labels over the sensor, opening supply stops, cleaning strainers or aerators, or replacing the battery.
For temperature-controlled models, the maintenance guide provides instructions for adjusting supply stops or rotating the mixing valve handle to achieve the desired water temperature.
The faucet's design also incorporates strainers (filters) to prevent clogging, which are user-serviceable. Instructions are provided for removing, cleaning, and reinstalling these strainers, or replacing them if necessary. Similarly, the aerator can be removed, cleaned, and reinstalled to address slow flow issues.
For cleaning the faucet's exterior, specific care instructions are provided to ensure its longevity and appearance. Users are advised to avoid abrasive or chemical cleaners, including chlorine bleach, as these can dull the luster and attack the chrome or decorative finishes. Instead, only mild soap and water should be used, followed by wiping dry with a clean cloth or towel. This gentle cleaning approach helps preserve the faucet's aesthetic integrity.
In cases where more complex issues arise, the manual directs users to contact Sloan Technical Support, ensuring professional assistance is available for troubleshooting and repairs beyond basic user maintenance. This support system is a crucial maintenance feature, providing a reliable resource for resolving persistent problems.
