To install the Rinnai CHP3PHAUX 3HP Auxiliary Relay Box, please follow these steps:

1. Before starting the installation, make sure to read the entire installation manual thoroughly to ensure safe and correct use of the appliance.

2. Ensure that the installation is done by an authorized person who is familiar with the manufacturer's instructions, local regulations, and municipal building codes.

3. Prior to installation, inspect the appliance for any damage or discrepancies. If any issues are found, immediately report them to the supplier.

4. The 3-phase auxiliary relay box must be directly connected to a 415 V AC 50 Hz mains power supply. It should be on its own circuit with an isolating switch installed at the switchboard. A secondary isolating switch should also be installed within reach of the box.

5. Connect all ACTIVE, NEUTRAL, and EARTH wires in accordance with the wiring diagram provided in the manual. Ensure that the incoming EARTH wire is securely fixed to the earth post.

6. Wire terminals "3" and "4" to the heat pump using a minimum 0.75mm2 two-core cable. The cable length should be less than 10 meters.

7. Connect all active, neutral, and earth wires directly from the contractor or terminals to the electric tank. Each 3-phase auxiliary relay box typically works with one electric tank. Refer to the electric tank wiring diagram for tank wiring.

8. Once the wiring is complete, double-check all connections to ensure they are secure and properly installed.

9. After installation, the appliance should be commissioned, serviced, and maintained by an authorized person in accordance with the manufacturer's instructions.
