Repair Parts for Thermostatic Units

The Eemax LavAdvantage is an electric instantaneous water heater designed to provide hot water solutions for various applications, primarily under-sink installations. These heaters are engineered for optimum performance and energy savings, heating cold or preheated water to suitable temperatures for domestic or sanitation use.

Function Description:

The LavAdvantage heater operates by heating water on demand, eliminating the need for a storage tank. It accepts either cold or preheated water and delivers hot water at a user-defined setpoint. The unit is designed to be installed under the sink, as close as possible to the point of use, and ideally below the point of use for best performance. This configuration ensures quick hot water delivery and minimizes energy waste. The heater is equipped with a control panel featuring two buttons ("-" and "+") for easy temperature adjustment and access to advanced functions. It also includes safety features such as an energy cut-off (ECO) and error code displays to ensure safe and reliable operation.

Important Technical Specifications:

The LavAdvantage series offers a range of models with varying electrical and heating capacities to suit different needs. Key specifications include:

Voltage (VAC): Models are available for 120V, 208V, 240V, and 277V electrical systems.
Max Power (kW): Power outputs range from 1.8 kW (SPEX1812T) to 11.5 kW (SPEX012240T) for 240V models, and up to 10 kW (SPEX100T) for 277V models.
Max Current (A): Current draw varies from 11A (SPEX3277T) to 48A (SPEX012240T), depending on the model and voltage.
Minimum Wire Size (AWG): Corresponding minimum wire sizes are specified, ranging from 14 AWG to 6 AWG, to ensure safe electrical installation.
Temperature Range: Standard models can heat water up to a maximum of 140°F (60°C). "S" option models can boost temperatures up to 180°F (82°C) for sanitation applications. "ML" option models are factory-set to a maximum of 110°F (43°C), with a range of 80°F-110°F (27°C-43°C), recommended for hand washing and sensor-type or metering faucets.
Minimum Working Pressure: 30 psi.
Maximum Operating System Pressure: 150 psi.
Optimum Operating Pressure: 35 - 80 PSI (a pressure reducing regulator is required for pressures over 80 PSI).
Fittings: Supplied with brass 3/8" compression fittings compatible with stainless steel flex hose, copper, or plastic pipe.
Aerators: "ML" thermostatic models are designed to deliver a minimum flow of 0.35 GPM to each lavatory, and specific aerators are supplied to ensure maximum heating performance.

Usage Features:

User Interface: The unit features a simple control panel with two buttons ("-" and "+") and a digital display.
Temperature Setting: Users can easily increase or decrease the setpoint temperature by tapping or holding the "+" or "-" buttons.
Advanced Functions: By simultaneously pressing both buttons for 3 seconds, users can access an advanced menu to view parameters such as:
- FLOW RATE (FLO): Displays water flow in GPM or LPM.
- INLET TEMPERATURE (IN): Shows the cold water inlet temperature in °F or °C.
- OUTLET TEMPERATURE (OUT): Shows the hot water outlet temperature in °F or °C.
- POWER FACTOR (PF): Indicates the heater's "working" percentage.
- SOFTWARE REVISION (SR): Displays the software version (for technical service).
Error Codes & Units: A dedicated menu, accessed by holding both buttons for 10 seconds, allows users to view current errors (CE), past errors (PE1-5), and switch between °F/GPM and °C/LPM units (UN). "F0" indicates no errors.
Automatic Display Turn-off: The temperature display turns off after 5 minutes of inactivity and reactivates when water flows through the heater or a button is pressed.
Commissioning Process: A guided commissioning process ensures proper setup, including purging air from the system and a 60-second countdown before heating begins.

Maintenance Features:

Periodic Cleaning: The heater is designed for low maintenance. To maintain consistent water flow, it may be necessary to periodically clean the faucet aerator or the filter screen located in the brass inlet fitting at the heater.
Troubleshooting Guide: The manual provides a comprehensive basic troubleshooting guide with fault codes (e.g., F23 for "No heat," F24 for "Low heat," F33 for "Shorted triac," F34 for "Overvoltage," F36 for "Undervoltage," F38 for "High flow," F47 for "Inlet thermistor failure," F48 for "Outlet thermistor failure," F64 for "Freeze protect," F83 for "Inverted flow"), possible causes, possible outcomes, and reset methods.
Repair Parts: A detailed list of repair parts is provided, including element cartridges, control boards, relays, and energy cut-off (ECO) components, along with their respective part numbers for various models.
Customer Support: Contact information for customer service and technical support is readily available, including phone numbers and email, to assist with any issues or parts inquiries.

The Eemax LavAdvantage is a robust and user-friendly electric instantaneous water heater designed for efficiency, convenience, and reliable hot water delivery in various residential and commercial settings.
