4. Installation Guide
4.1 Pre-installation Requirements
Before beginning installation, ensure you have the correct electrical and plumbing setup. This unit requires a dedicated 240V electrical supply with a 1x40AMP Double Pole breaker and 8AWG/2 wires with grounding. Plumbing connections should be 1/2" NPT.
Consider your geographical location and desired hot water flow rate. For northern regions, the unit is recommended for a single faucet (less than 1.2 GPM). In southern regions, it may support two faucets or a shower. Refer to the flow rate guide below to determine if the 8kW unit is suitable for your needs.

It also provides a table of advised flow rates (GPM) at 108°F for an 8kW unit based on inlet temperature, and a guide to calculate simultaneous fixture usage for faucets, sinks, shower heads, bathtubs, dishwashers, and laundry.
4.2 Mounting the Unit
Use the provided mounting template to mark the drilling locations on the wall. Ensure the mounting surface is sturdy and capable of supporting the unit's weight. Securely fasten the mounting bracket using the supplied wall anchors and screws.
