CHECKING CORRECT GROUNDING
If the power distribution circuit does not have a grounding or the grounding does not comply with specifications, an
A grounding electrode must be installed. The corresponding accessories are not supplied with the Air to Water Heat
pump.
1. Select a grounding electrode that complies with the specifications given in the illustration.
2. Connect the flexible hose to the flexible hose port.

In damp hard soil rather than loose sandy or gravel soil that has a higher grounding resistance.

Away from underground structures or facilities, such as gas pipes, water pipes, telephone lines, and underground
cables.

At least two meters away from a lightning conductor grounding electrode and its cable.
The grounding wire for the telephone line cannot be used to ground the Air to Water Heat pump.
3. Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit.
4. Install a green/yellow colored grounding wire:

If the grounding wire is too short, connect an extension lead, mechanically and wrap it with insulating tape.

(Do not bury the connection).

Secure the grounding wire in position with staples.
If the grounding electrode is installed in an area of heavy traffic, its wire must be connected securely.
5. Carefully check the installation by measuring the grounding resistance with a ground resistance tester. If the resistance
is above the required level, drive the electrode deeper into the ground or increase the number of grounding electrodes.
6. Connect the grounding wire to the electrical component box inside the outdoor unit.
