4. Installation Guide

Important: Installation must be performed by a qualified professional in compliance with all local and national electrical and plumbing codes.

4.1 Pre-Installation Requirements

• Electrical: Requires 240V power supply. A dedicated 1x40AMP Double Pole Breaker is necessary. Use 8AWG/2 wires with Grounding.
• Plumbing: Pipe fittings are 1/2" NPT. Ensure adequate water pressure.
• Location: Choose a wall-mounted location that is easily accessible for maintenance, protected from freezing, and close to the point of use.

4.2 Flow Rate Selection Guide

Determine the appropriate flow rate for your region and desired outlet temperature to ensure optimal performance. Refer to the guide below:

Image 4.1: Flow rate selection guide, including a map indicating typical inlet water temperatures by region and a table detailing gallons per minute (GPM) at 108°F for different inlet temperatures. It also provides GPM estimates for common fixtures.

Steps for Flow Rate Selection:

1. Find Your Location: Use the provided map to identify your region's average inlet water temperature.
2. Check Advised Flowrate: Refer to the table to find the GPM at 108°F for your inlet temperature.
3. Calculate Fixtures: Estimate the total GPM required for fixtures that may run simultaneously to determine if one 8kW unit is sufficient.
