The Elkay EZH2O Refrigerated Surface Mount Bottle Filling Station (series EZ8WS & LZ8WS) is a drinking water appliance designed for indoor use, providing filtered (LZ models) or non-filtered (EZ models) water. It features a bottle filling station with an infrared (IR) sensor for touchless operation and a bottle counter display.
Function Description:
The primary function of this device is to dispense potable water, offering a convenient and hygienic way to refill water bottles. The refrigerated models provide chilled water. The bottle filling station is equipped with an IR sensor that detects the presence of a bottle or hand, initiating water flow. A digital display shows the number of plastic bottles saved, promoting environmental awareness. Filtered models (LZ series) incorporate a water filter to improve water quality, with a filter monitor indicating filter status (Green, Yellow, Red) and capacity.
Important Technical Specifications:
- Water Supply Pressure: The unit is designed to operate with a water supply pressure between 20 psi and 105 psi. For LZ filtered units, a minimum of 40 psi is required to ensure adequate water flow. Pressures outside this range can damage the product and affect performance.
- Electrical Supply: The unit requires a 115 Volt, 60 Hz AC electrical supply. It should be installed on a dedicated 20A fused circuit. A Ground-Fault Circuit Interrupter (GFCI) may be required, and a 20 amp hospital grade GFCI protection device is suggested for optimal performance.
- Water Inlet: The water supply line should be at least 3/8" O.D. unplated copper tube, extending a maximum of 3" (76mm) from the wall. A quarter-turn, installer-supplied shut-off valve is required. A dielectric coupling and a non-metallic strainer are furnished to prevent electrolysis.
- Waste Outlet: The waste outlet must be a minimum of 1-1/4" O.D. for single units, with the pipe extending 2" (50mm) from the wall. A plastic P-trap with a 1-1/4" inlet (installer-supplied) is recommended to isolate the cooler from the building plumbing system.
- Mounting: The unit is a surface-mount design, requiring secure wall support for the hanger bracket. Twelve 7/16" (11mm) bolt holes are used for fastening to the wall for the cooler, and six 7/16" screws for the bottle filler mounting plate.
- Ventilation: Proper ventilation is crucial, requiring a minimum of 6" (152mm) clearance from cabinet louvers to the wall.
- Dimensions: The overall height from the floor to the top of the unit is approximately 53.04 inches (1347mm). The basin height is 34.12 inches (867mm).
Usage Features:
- Touchless Operation: The bottle filler utilizes an IR sensor for hands-free dispensing, enhancing hygiene.
- Bottle Counter: A digital LCD display tracks the number of plastic bottles saved, providing a visual reminder of environmental impact.
- Filter Monitor (LZ Only): For filtered units, an LED light indicates the filter status:
- GREEN: 0-80% of Filter Life or 0-11 Months remaining.
- YELLOW: 80-100% of Filter Life or 11-12 Months remaining (whichever comes first).
- RED: 100% Plus of Filter Life or 12 Months (whichever comes first), indicating the filter needs replacement.
- Adjustable IR Sensor Range: The sensitivity of the IR sensor can be adjusted from 1 (closest to sensor) to 10 (farthest away) through the programming menu, allowing customization based on user preference and installation environment.
- Unit Type Setting: The unit type (refrigerated or non-refrigerated) can be configured in the programming menu.
- Filter Capacity Setting (LZ Only): The filter capacity can be set to 3000 GAL or 6000 GAL in the programming menu, aligning with the installed filter type.
Maintenance Features:
- Filter Replacement (LZ Only): The filter cartridge is easily installed by inserting it into the filter head and rotating clockwise. The filter label should be readable from the front.
- Reset Filter Monitor (LZ Only): After replacing the filter, the filter monitor can be reset through the programming menu, which will illuminate the green LED.
- Reset Bottle Count: The bottle counter can be reset to zero through the programming menu. Note that resetting the count is irreversible.
- Easy Access for Maintenance: The front cover of the cooler and the top cover of the bottle filler are removable, providing access to internal components for installation and maintenance.
- Troubleshooting: The manual provides instructions for checking for water leaks and bleeding air from supply lines after installation.
The manual emphasizes safety with warnings regarding personal injury, property damage, shock, and electrocution hazards. It stresses the importance of reading and understanding all instructions, using proper tools, wearing personal protective equipment (safety glasses, hearing protection, gloves), and ensuring all electrical and plumbing work complies with local codes. Specific warnings include:
- Never using electric power tools around water or wet surfaces.
- Keeping liquids away from electrical cords and power tools.
- Ensuring all related circuit breakers are turned OFF before working on electrical components.
- Testing for live circuits before cutting or drilling into walls.
- Using two people to lift the heavy unit to prevent bodily injury.
- Using a GFCI-protected circuit for power tools and the unit itself.
- Not modifying the supplied power cord or using adapters/extension cords.
- Ensuring proper ventilation to prevent damage to the product.
The Elkay EZH2O bottle filling station is designed for reliable and safe operation when installed and maintained according to the provided instructions.
