Eemax LavAdvantage SPEX55T-ML Multi-Lav Tankless Water Heater | 5.5kW 240V

Product Details

The Eemax SPEX55T-ML is a specialized "Multi-Lavatory" version of the renowned LavAdvantage series. This 5.5kW, 240V unit is engineered to provide hot water to multiple handwashing fixtures simultaneously, making it a favorite for commercial restrooms. The "ML" designation indicates that the unit is factory-calibrated with a maximum temperature setting of 110°F, specifically to comply with ADA and safety codes for public handwashing. By using advanced thermostatic technology, it maintains a precise temperature output even as different sinks are turned on and off, ensuring a safe and consistent experience for all users.

Key Features:

• Multi-Lavatory Optimization: Designed to serve multiple low-flow faucets (up to 3 sensor faucets at 0.5 GPM each) from a single compact unit.
• Factory-Set Safety: The "ML" (Multi-Lav) model is factory-limited to a maximum of 110°F, ensuring immediate compliance with safety regulations and preventing accidental scalding in public spaces.
• Thermostatic Precision: Microprocessor-controlled logic ensures the water temperature remains within $+/- 1^\circ\text{F}$ of the set point, regardless of pressure fluctuations.
• Ultra-Low Flow Activation: Triggers at just 0.3 GPM, ensuring the heater engages even when used with the most efficient water-saving fixtures.
• Mount-Anywhere Design: The compact, durable chassis can be installed in any orientation (360-degree mounting) to accommodate complex under-sink plumbing.

Specifications:

• Power Rating: 5.5 kW
• Voltage: 240V (Can operate at 208V with 4.1kW output)
• Amperage Draw: 23 Amps
• Required Breaker: 30 Amp
• Recommended Wire Size: 10 AWG
• Water Connections: 1/2" NPT
• Factory Set Temp: 110°F (Adjustable 100°F - 110°F)
• Dimensions: 9.75" H x 5.25" W x 3" D

Installation & Maintenance Tips:

• ADA Compliance: Because the temperature is capped at 110°F, this unit is ideal for projects requiring strict adherence to ADA and ASSE 1070 mixing valve standards (always check local codes).
• Circuit Loading: This is a 23-amp unit. Ensure it is on a dedicated 30-amp circuit. For 208V commercial buildings, remember that the "ML" performance will be slightly reduced.
• Parallel Plumbing: When serving multiple sinks, use a manifold or balanced piping to ensure equal flow to all faucets.
• Clean the Screen: Sediment in the inlet filter can prevent the high-sensitivity flow sensor from activating. Inspect and clean the filter every 6-12 months.

Common Uses/Applications:

• Public Commercial Restrooms: The standard choice for malls, airports, and stadiums where multiple users wash hands at once.
• Office Buildings: Efficiently serves a bank of 2 or 3 sensor-operated sinks in a shared washroom.
• Schools & Daycares: Provides the safety-capped temperature control required for child-safe handwashing stations.
• Healthcare Facilities: Reliable, consistent heat for patient room sinks and staff hand-wash areas.

Common Questions:

Q: Can I turn the temperature up to 140°F?

A: No. The "ML" series is specifically designed for handwashing and is capped at 110°F. For higher temperature applications, use the standard **SPEX55T**.

Q: Do I still need a separate thermostatic mixing valve?

A: In many cases, no. Because the SPEX-ML is an ASSE 1070 compliant-capable device that limits the temperature electronically, it often removes the need for an external mixing valve at the sink.

Q: How many sinks can this actually handle?

A: It depends on the flow rate. It can comfortably support two 0.5 GPM faucets simultaneously in most climates, or three ultra-low-flow 0.35 GPM faucets.

The Eemax SPEX55T-ML LavAdvantage is the professional’s answer to safe, multi-user handwashing, delivering code-compliant hot water in a single, high-efficiency package.
